A children's library has 5 storybooks for every 3 science books it has. The library also has the same number of picture books as science books. The library added 50 more picture books so now there are the same number of picture books as storybooks. How many of each of the book does the children's library have? Draw a model

Answers

Answer 1

The children's library has 75 science books, 125 picture books, and 125 storybooks.

How to solve for the number of books

z = 5x/3 (5 storybooks for every 3 science books)

y = x (the same number of picture books as science books)

y + 50 = z (the library added 50 more picture books so now there are the same number of picture books as storybooks)

Now, we can substitute the equations to solve for the number of each type of book:

From equation 2, we know that y = x. So, we can rewrite equation 3 as:

x + 50 = z

Now, we can substitute equation 1 into this equation:

x + 50 = 5x/3

Multiply both sides by 3 to eliminate the fraction:

3(x + 50) = 5x

3x + 150 = 5x

Subtract 3x from both sides:

150 = 2x

Divide both sides by 2:

x = 75

So, there are 75 science books in the library. Now we can find the number of picture books (y) and storybooks (z):

y = x = 75 (75 picture books before adding 50 more)

y = 75 + 50 = 125 (125 picture books after adding 50 more)

z = 5x/3 = (5 * 75) / 3 = 375 / 3 = 125 (125 storybooks)

So, the children's library has 75 science books, 125 picture books, and 125 storybooks.

One medical procedure used today allows parents to select the gender of their future baby. The procedure has been found to be effective 75% of the time, meaning that 75% of the time parents get a baby of the preferred gender. Suppose this method is used by 5 couples at one particular clinic. For #6 and 7, write the numeric value and write in words what it represents

Answers

6. The probability that all 5 couples will have a baby of the preferred gender is 0.2373.

7. The probability that at least 4 of the 5 couples will have a baby of the preferred gender is 1 - 0.3672 = 0.6328.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to predict with absolute certainty.

6. What is the probability that all 5 couples will have a baby of the preferred gender?

Answer: The probability that one couple will have a baby of the preferred gender is 0.75. Assuming the gender of each baby is independent of the others, the probability that all 5 couples will have a baby of the preferred gender is 0.75⁵ = 0.2373.

Numeric value: 0.2373

In words: The probability that all 5 couples will have a baby of the preferred gender is 0.2373.

7. What is the probability that at least 4 of the 5 couples will have a baby of the preferred gender?

Answer: There are two ways to approach this problem. One way is to calculate the probability of each possible outcome (0 to 5 couples having a baby of the preferred gender) and then add up the probabilities for the outcomes where at least 4 couples have a baby of the preferred gender. Another way is to use the complement rule and subtract the probability that fewer than 4 couples have a baby of the preferred gender from 1.

Using the first method, we can calculate the probabilities as follows:

- 0 couples: 0.25⁵ = 0.0009766

- 1 couple: 5 x 0.75 x 0.25⁴ = 0.01465

- 2 couples: 10 x 0.75² x 0.25³ = 0.08789

- 3 couples: 10 x 0.75³ x 0.25² = 0.2637

- 4 couples: 5 x 0.75⁴ x 0.25 = 0.3955

- 5 couples: 0.75⁵ = 0.2373

The probabilities for the outcomes where at least 4 couples have a baby of the preferred gender are 0.3955 and 0.2373, so the total probability is 0.3955 + 0.2373 = 0.6328.

Using the second method, we can calculate the probability that fewer than 4 couples have a baby of the preferred gender as follows:

- 0 couples: 0.25⁵ = 0.0009766

- 1 couple: 5 x 0.75 x 0.25⁴ = 0.01465

- 2 couples: 10 x 0.75² x 0.25³ = 0.08789

- 3 couples: 10 x 0.75³ x 0.25² = 0.2637

The probability that fewer than 4 couples have a baby of the preferred gender is the sum of these probabilities: 0.0009766 + 0.01465 + 0.08789 + 0.2637 = 0.3672.

Therefore, the probability that at least 4 of the 5 couples will have a baby of the preferred gender is 1 - 0.3672 = 0.6328.

Assume that a cell is a sphere with radius 10-3 or 0.001 centimeter, and that a cell’s density is 1.1 grams per cubic centimeter. koalas weigh 6 kilograms on average. how many cells are in the average koala? hippos weigh 1,400 kilograms on average. how many cells are in the average hippo? solution

Answers

There would be   1.302 x 10¹² cells in koala, and  there are  3.04 x 10^17 cells in the average hippo.

To find the number of cells in the average koala, we first need to find the volume of the koala in cubic centimeters, since we know the density of the cell and can use that to find the mass of the koala in grams.

The average weight of a koala is 6 kilograms, which is equivalent to 6,000 grams. We can use the density of the cell to find the volume of the koala:

Density = Mass / Volume

1.1 g/cm³ = 6,000 g / Volume

Volume = 6,000 g / 1.1 g/cm³

Volume = 5,454.54 cm³

Next, we need to find the volume of one cell:

Volume of cell = 4/3 * π * (0.001 cm)³

Volume of cell = 4.188 x 10⁻⁹ cm³

Finally, we can divide the volume of the koala by the volume of one cell to find the number of cells in the average koala:

Number of cells = 5,454.54 cm³ / (4.188 x 10⁻⁹ cm³)

Number of cells = 1.302 x 10¹²

Therefore, there are approximately 1.302 x 10¹² cells in the average koala.

To find the number of cells in the average hippo, we can follow the same process. The average weight of a hippo is 1,400 kilograms, which is equivalent to 1,400,000 grams. Using the density of the cell, we can find the volume of the hippo:

Density = Mass / Volume

1.1 g/cm^3 = 1,400,000 g / Volume

Volume = 1,400,000 g / 1.1 g/cm³

Volume = 1,272,727.27 cm³

Dividing the volume of the hippo by the volume of one cell, we get:

Number of cells = 1,272,727.27 cm³ / (4.188 x 10⁻⁹ cm³)

Number of cells = 3.04 x 10¹⁷

Therefore, there are approximately 3.04 x 10¹⁷ cells in the average hippo.

Josh and Draven can clean the JHS cafeteria in 25 minutes. Draven can clean the JHS cafeteria in 40 minutes. How long will it take Josh to do the job if he works alone?

Answers

It will take Josh about 66.67 minutes to easy the cafeteria alone.

Let's anticipate that the amount of work required to easy the cafeteria is 1 unit.

In a single minute, Josh can easy 1/x of the cafeteria (in which x is the number of mins it takes Josh to do the task alone), and Draven can clean 1/40 of the cafeteria in one minute.

When they work together, they could easy the cafeteria in 25 minutes, so in one minute they are able to easy 1/25 of the cafeteria.

The use of the fact that their combined rate is the sum in their individual rates, we are able to installation an equation:

1/x + 1/40 = 1/25

Multiplying each facets through the least common more than one of the denominators (40 * 25 * x), we get:

25 * 40 + x * 40 = x * 25

1000 + 40x = 25x

mAngleX < mAngleZ < mAngleY
mAngleY < mAngleZ < mAngleX
mAngleY < mAngleX < mAngleZ
mAngleZ < mAngleY < mAngleX

Answers

Answer:

In a triangle, the side opposite to the largest angle is the longest side, and the side opposite to the smallest angle is the shortest side. In triangle XYZ, the length of side XY is m + 8, the length of side YZ is 2m + 3, and the length of side ZX is m - 3. Since m ≥ 6, we can determine that 2m + 3 is the largest value, m + 8 is the next largest value, and m - 3 is the smallest value. Therefore, side YZ is the longest side and side ZX is the shortest side.

Since side YZ is the longest side, angle X must be the largest angle. Since side ZX is the shortest side, angle Y must be the smallest angle. Therefore, the correct ordering of the angles from smallest to largest is ∠Y < ∠Z < ∠X.

Answers

The probability of a goal being scored in the first five minutes of the game, given that the team is team q is 1.24%. The correct option is a.

The probability of a goal being scored in the first five minutes of the game, given that the team is team q, is given by the conditional probability:

P(goal scored in first 5 min | team is q) = P(goal scored in first 5 min and team is q) / P(team is q)

From the table, we have:

P(goal scored in first 5 min and team is q) = 3.56%

P(team is q) = 3.56%

Therefore:

P(goal scored in first 5 min | team is q) = 3.56% / 3.56% = 1

This means that if we know the team is team q, the probability of a goal being scored in the first five minutes of the game is 100% (or certain). So the correct answer is (a) 1.24%.

Simplify this expression using the rule of exponents?

We can simplify this expression using the rule of exponents that states a^m / a^n = a^(m-n), which gives:

6 * 6^(-2) = 6 / 6^2 = 6 / 36 = 1/6

Let's break down the expression and simplify it step by step:

You find an apartment which charges $925 a month rent. each year the rent increases by 6%.

Answers

The monthly rent for the apartment would be $1238.84 in the fifth year.

What is the monthly rent for an apartment that charges $925 initially and increases by 6% each year?

The problem states that the monthly rent for an apartment is $925. To calculate the rent for the second year, we need to increase this amount by 6%.

To do this, we first need to calculate 6% of $925. We can do this by multiplying 0.06 (which is equivalent to 6%) by $925:

6% of $925 = 0.06 × $925 = $55.50

So, the rent for the second year would be:

$925 + $55.50 = $980.50

To find the rent for the third year, we need to increase the rent for the second year by 6%. We can follow the same process:

6% of $980.50 = 0.06 × $980.50 = $58.83

So, the rent for the third year would be:

$980.50 + $58.83 = $1039.33

To find the rent for any year n, we use the formula:

Rent for year n = $925 × (1 + 0.06)^n

In this formula, (1 + 0.06) represents the multiplier used to calculate the new rent each year.

For example, the multiplier for the second year is 1 + 0.06 = 1.06, and the multiplier for the third year is 1.06 × 1.06 = 1.1236 (rounded to four decimal places).

To find the rent for the fifth year, we plug in n = 5:

Rent for year 5 = $925 × (1 + 0.06)^5 = $925 × 1.3382 = $1238.84 (rounded to the nearest cent)

So, the monthly rent for the apartment would be $1238.84 in the fifth year.

Answers

Ben could have saved $0.15 per gallon if he had gone to the gas station across the street.

If Ben filled his 20-gallon tank of gas with regular fuel for $59.80, then the cost per gallon can be found by dividing the total cost by the number of gallons:

cost per gallon = total cost / number of gallons

cost per gallon = $59.80 / 20 gallons

cost per gallon = $2.99/gallon

If the gas station across the street sold regular fuel for $2.84 a gallon, then the amount Ben could have saved per gallon is:

savings per gallon = cost per gallon at initial station - cost per gallon at other station

Answers

The predicted populations of rabbits in the warren in 2008 and 2022 are 2909 and 9933, respectively.

To predict the population of rabbits in the warren in 2008 and 2022, we can use the formula for exponential growth:
P(t) = P₀ (1 + r)ᵗ

Where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t is the time elapsed.

For this problem, we know that P₀ = 1500, r = 0.07 (since the growth rate is 7%), and we want to find P(8) and P(22) (since we're predicting the population in 2008 and 2022, respectively).

Using the formula, we get:
[tex]P(8) = 1500( 1 + 0.07)^{8}  = 2909[/tex]

So we can predict that there will be about 2909 rabbits in the warren in 2008.

To find P(22), we simply plug in t = 22:
[tex]P(22) = 1500 (1 + 0.07)^{22}  = 9933[/tex]

So we can predict that there will be about 9933 rabbits in the warren in 2022.

So, Susan spent $5.12 on ribbon.  We also know that each yard of ribbon was $0.16, so we can divide the spent amount ($5.12) by $0.16 to find out how many yards she bought:

5.12/0.16

=32

So, Susan bought 32 yards of ribbon.

Hope this helps :)

This equation shows how the cost of a plumber's visit is related to its duration in hours. C = 51d

The variable d represents the duration of the visit in hours, and the variable c represents the cost. If a plumber's visit lasted 1 hour, how much would it cost?

Answers

The cost of a plumber's one-hour visit is $51, determined by the linear equation C = 51d, where C is the cost and d is the duration of the visit in hours.

How is the cost of a plumber's visit determined by duration?

If a plumber's visit lasts for a certain duration, the cost can be determined using the equation

                           C = 51d

where C is the cost and d is the duration of the visit in hours.

In this case, the duration of the plumber's visit is given as 1 hour. Substituting d = 1 in the equation, we get

                             C = 51(1) = $51

as the cost of the plumber's visit.

Therefore, if the plumber's visit lasts for one hour, it would cost $51 according to the given equation.

This cost may vary if the duration of the visit changes, as it is directly proportional to the duration of the visit.

The length of the radius of a sphere is 6 inches. The length of the radius of a cone is 3 inches, and the height is 7 inches. What is the difference between the volume of the sphere and the volume of the cone?

Answers

The difference between the volume of the sphere and the volume of the cone is approximately 838.81 cubic inches.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius. Thus, for a sphere with a radius of 6 inches, the volume is:

V_sphere = (4/3)π(6³) = 904.78 cubic inches

The volume of a cone is given by the formula V = (1/3)πr[tex]^{2h}[/tex], where r is the radius and h is the height. Thus, for a cone with a radius of 3 inches and a height of 7 inches, the volume is:

V_cone = (1/3)π(3²)(7) = 65.97 cubic inches

Therefore, the difference between the volume of the sphere and the volume of the cone is:

V_sphere - V_cone = 904.78 - 65.97 = 838.81 cubic inches

Hence, the difference between the volume of the sphere and the volume of the cone is approximately 838.81 cubic inches.

2. Hamilton claimed that there are only 4 circuits that begin with the letters LTSR Q. Find them. 3. Find all four possible Hamiltonian circuits that begin with JVTSR

Answers

To find the possible Hamiltonian circuits that begin with JVTSR, we can start by constructing a path that begins with JVTSR and visits each vertex exactly once. Such a path must be of the form JVTSRX, where X is the remaining vertex.

Case 1: JVTSRQX

To find the possible value of X, we note that the only edges incident to J are V and T, and the only edges incident to Q are S and R. Thus, we must have X = S or X = R, and the circuits are JVTSRQS and JVTSRQR.

Case 2: JVTSRXQ

To find the possible value of X, we note that the only edges incident to X are S and L. Thus, we must have X = L, and the circuit is JVTSRLQ.

Case 3: JVTSRLX

To find the possible value of X, we note that the only edges incident to J are V and T, and the only edges incident to L are T and R. Thus, we must have X = R, and the circuit is JVTSRLR.

Case 4: JVTSRXL

To find the possible value of X, we note that the only edges incident to Q are S and R, and the only edges incident to X are L and S. Thus, we must have X = L, and the circuit is JVTSRQL.

Therefore, there are four possible Hamiltonian circuits that begin with JVTSR: JVTSRQS, JVTSRQR, JVTSRLQ, and JVTSRLR.

if an airplane travels around the world, flying just above the equator it would travel 1.25 x 10^4 miles. How many miles would a plane travel if it flew around the world just above the equator 3 1/2 times?

(in standard form)

Answers

A plane flying just above the equator around the world 3 1/2 times would cover a distance of 4.375 x 10⁴ miles.

If an airplane travels around the world just above the equator once, it covers a distance of 1.25 x 10⁴ miles. To find how many miles it would cover if it flew around the world 3 1/2 times, we need to multiply this distance by 3.5:

1.25 x 10⁴ miles x 3.5 = 4.375 x 10⁴ miles

To understand this calculation, we need to know that 3 1/2 times means 3.5 times. So, we multiply the distance covered in one round of the world by 3.5 to find the total distance covered in 3 1/2 times around the world.

We use standard form to express the answer in a more compact and convenient way, where 4.375 x 10⁴ represents the number 43,750 in scientific notation.

The velocity of a particle moving in a straight line is given by v = t(t^2 + 1)^3 + 3t. (a) Find an expression for the position s after a time t. (Use C for the constant of integration)
S =

Answers

The position of particle in a straight line with v = t(t^2 + 1)³ + 3t is (1/8)t⁸ + (3/6)t⁶ + (3/4)t⁴ + 2t² C.

To find an expression for the position s after a time t, we need to integrate the velocity function v with respect to time t.

Using the power rule of integration and the constant of integration C, we have:

s = ∫v dt = ∫[t(t² + 1)³ + 3t] dt

after expanding t(t² + 1)³ using binomial theorem we have-

(t^2 + 1)³ = t⁶ + 3t⁴ + 3t² + 1

Substituting this into the integral, we get:

s = ∫[t(t⁶ + 3t⁴ + 3t^2 + 1) + 3t] dt

s = ∫[t^7 + 3t⁵ + 3t³ + t + 3t] dt

s = ∫t^7 dt + 3∫t⁵ dt + 3∫t³ dt + ∫4t dt

s = (1/8)t⁸ + (3/6)t⁶ + (3/4)t⁴ + 2t² + C

Therefore, the expression for the position s after a time t is:

S = (1/8)t⁸ + (3/6)t⁶ + (3/4)t⁴ + 2t² + C, where C is the constant of integration.

Find the x- and y-intercepts of the graph of 4x+8y=20. State each answer as an integer or an improper fraction in simplest form

Answers

The cordinate points with x- and y-intercepts of the graph of a linear equation, 4x+ 8y = 20, are equals to the (5,0) and (0, 5/2).

We have an equation, 4x + 8y = 20 --(1) which is linear equation with two variables. We have to determine the the x- and y-intercepts of the graph of equation (1). The graph of line (1) is present in above figure. Slope intercept form of equation (1) is written as [tex]y = - \frac{1}{2}x + \frac{5}{2}[/tex],

The x-intercept is point where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. As we know, two points determine any line, we can graph lines using the x- and y-intercepts. To determine the x-intercept, we substitute y=0 and solve for x. So, when y = 0 then 4x + 0 = 20

=> x = 5

similarly to determine the y-intercept, set x=0 and solve for y. When x = 0

=> 8y = 20

=> y = 5/2.

Hence, required value are (5,0) and (0,5/2).
