Answer:

0.75 gallons

Step-by-step explanation:

As the statement indicates that Latrell wants the bedroom ceiling to be 85% blue and 15% white and you know that he needs 4.25 gallons of blue which represents the 85%, you can use a rule of three to find the amount that represents the 15% to know the gallons of white that he needs:

4.25 gallons → 85%

          x         ←  15%

x= (4.25*15)/85

x=0.75

According to this, the answer is that if Latrell needs 4.25 gallons of blue, he needs 0.75 gallons of white.

Answer:

Step-by-step explanation:

Diameter = 18cm

18 / 2 = Radius

Radius = 9cm

Formula: A=2πrh+2πr^2

2 x pi x 9 x 0.3 + 2 x pi x 9^2 = 525.90261

Nearest hundredth = 525.90

Answer:189.25 cm  189.3 cm if rounded to one decimal point

Step-by-step explanation:

You need to find the area of the rectangle, then the area of 1/2 the circle.

Rectangle Area =

L x w =

10 x 15 = 150cm

Circle Area =

A=πr^2 =

Diameter = 10, so radius = 5

π(5)^2 = 25π = (25)(3.14) = 78.5

Area of 1/2 Circle = 78.5/2 = 39.25

150 + 39.25 = 189.25 cm

Answer:

-3

Step-by-step explanation:

2x-1=4x+5

-1=2x+5

-6=2x

x=-3

Answer:

x = -3

Step-by-step explanation:

Solve for x:

2 x - 1 = 4 x + 5

Subtract 4 x from both sides:

(2 x - 4 x) - 1 = (4 x - 4 x) + 5

2 x - 4 x = -2 x:

-2 x - 1 = (4 x - 4 x) + 5

4 x - 4 x = 0:

-2 x - 1 = 5

Add 1 to both sides:

(1 - 1) - 2 x = 1 + 5

1 - 1 = 0:

-2 x = 5 + 1

5 + 1 = 6:

-2 x = 6

Divide both sides of -2 x = 6 by -2:

(-2 x)/(-2) = 6/(-2)

(-2)/(-2) = 1:

x = 6/(-2)

The gcd of 6 and -2 is 2, so 6/(-2) = (2×3)/(2 (-1)) = 2/2×3/(-1) = 3/(-1):

x = 3/(-1)

Multiply numerator and denominator of 3/(-1) by -1:

Answer: x = -3

Answer:

At the average rate of making profit, it will take slightly more than 30 hours for the business to reach a profit goal of $500. (30.075)

Step-by-step explanation:

a) It is not clear what linear equation is desired. We are given enough information to write an equation relating the number of bracelets produced by each worker to the time it takes.

Let n represent the number of bracelets Danica produces. Let r represent the number of bracelets Darrelle produces. Let h represent time in hours.

.. r/3 = h/4 ... Darrelle produces 3 bracelets in 4 hours

.. 4r - 3h = 0 ... equation in standard form

.. r = (3/4)h ... equation in slope-intercept form (the intercept is 0)

.. n/5 = h/2 ... Danica produces 5 bracelets in 2 hours

.. 2n - 5h = 0 ... equation in standard form

.. n = (5/2)h ... equation in slope-intercept form

b) We have no idea what special functions were discussed in the course. Of course these equations can be graphed. (2-dimensional equations are easily graphed.)

c) A profit function can be written in terms of the number of bracelets produced. Then it can be solved to find when (h=?) profit is equal to $500.

.. Let p represent the total profit from production of bracelets.

.. p = 10.50*r + 3.50*n ... profit in terms of bracelets produced

.. p = 10.50*((3/4)h) + 3.50*((5/2)h) ... profit in terms of hours, where both work the same hours

.. p = 16.625 h

.. 500 = 16.625 h ... we want to find hours until $500 profit

.. 500/16.625 = h ≈ 30.0752

At the average rate of making profit, it will take slightly more than 30 hours for the business to reach a profit goal of $500.

_____

If you work out the timing of when bracelets are finished, assuming they are made at a constant rate, you find that there will be 23 of Darrelle's bracelets and 76 of Danica's bracelets finished in 30 hours and 40 minutes. These will yield a profit of $507.50. After another 8 minutes, Danica will have finished bracelet 77 to add another $3.50 to the profit total.

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan15° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{20}{x}[/tex] ( multiply both sides by x )

x × tan15° = 20 ( divide both sides by tan15° )

x = [tex]\frac{20}{tan15}[/tex] ≈ 74.6 ft ( to the nearest tenth of a foot )

Answer:

[tex](x-7)(x-7)[/tex]

Step-by-step explanation:

We begin with the given quadratic expression:

[tex]49-14x+x^2[/tex]

Just for my own ease, I will rewrite this in descending order of powers

[tex]x^2-14x+49[/tex]

In order to factor this expression, we need to look for two numbers that meet the following criteria.

When they are added together, you get [tex]-14[/tex]

When they are multiplied together, you get [tex]49[/tex]

A simple way to find our answer is to begin with the product of multiplication and list each of the numbers that can be multiplied together to get us our given result

To get 49, we could multiply

1 and 49

-1 and -49

7 and 7

-7 and -7

Now, we can just add both of these terms together to see while one gives us our desired result

[tex]1+49=50\\-1-49=-50\\7+7=14\\-7-7=-14[/tex]

As you can see, -7 and -7 were the two values that gave us -14.

This means that they are the terms within our factor.

Therefore, our factored form would be [tex](x-7)(x-7)[/tex]

Answer:

(7 - x) (7 - x)

Step-by-step explanation:

First, I'm multiplying 49 by the co-efficient of x(1) to get 49. Then I'm going to see what factors of 49 add up to -14. Those are -7 and -7.

Next, I'm going to rewrite this polynomial:

49 - 7x - 7x + x^2

Then, I group them into two groups:

49 - 7x

&

-7x + x^2

Then, I factor them out:

49 - 7x = 7 (7 - x)

-7x + x^2 = -x (7 - x)

After that, I take the outer coefficients and put them in parenthesis:

7 (7 - x)

&

-x (7 - x)

= (7 - x)

Finally, I put both of our grouped parenthesis together:

(7 - x) (7 - x)

Answer:

True

Step-by-step explanation:

Example: sqrt(5) (which decimals continue forever) will mean that if you did 5+sqrt(5) it would still have those decimals.

Answer:

True. By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal, so the result is irrational.

Answer:

b = 3Vh

Step-by-step explanation:

When they ask to solve for b, you are essentially rearranging the equation so that b is alone on one side.

V = 1/3bh

(V)(3) = (1/3bh)(3)

3V = bh

(3V)/h = (bh)/h

3Vh = b

b = 3Vh

168.75ft

Step-by-step explanation:

We can just multiply by the scale

2.25*75=168.75

The actual height of the tree is 168.75 ft.          

The height is defined as the measurement of the distance of an object from the base to the top.

Here, Given

Height of tree (in drawing) = 2.25 inches

Scale is given ; 1 inch = 75 ft.

       so, 2.25 inches = 2.25 X 75 ft.

                                  ≈ 168.75 ft.

Thus, the actual height of the tree is 168.75 ft.

Step-by-step explanation:

Given: A solution contains 4.3 grams of salt per liter.

To find: Amount of salt in 11 liters of the solution

Solution:

Amount of salt in 1 liter of the solution = 4.3 grams

So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams

Hence, 11 liters of the solution contains 47.3 grams of salt.

Answer:

q = 15

Step-by-step explanation:

→First, add 18q to both sides:

-15 - 18q = -20q + 15

-15 = -2q + 15

→Subtract 15 from both sides:

-30 = -2q

→Divide both sides by -2:

15 = q

We first want to get q on its own then solve like shown:

-15-18q=-20q+15

Now add 15 to both sides and add 20 q to both sides.

2q=30

Now divide 30 by 2.

q=15
