Answer:

  1 2/3

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.

The value of x from the expression is,

⇒ x = 1/4 (Y - 3)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ Y = 4x + 3

Now, We can solve the expression for the value of x as;

⇒ Y = 4x + 3

Subtract 3, we get;

⇒ Y - 3 = 4x + 3 - 3

⇒ Y - 3 = 4x

Divide by 4;

⇒ (Y - 3) / 4= 4x/4

⇒ (Y - 3)/4 = x

⇒ x = 1/4 (Y - 3)

Step-by-step explanation:

The expression that indicates the amount of water, in gallons, in the swimming pool after m minutes is 1600 + 25m.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

In this case, there are already 1,600 gallons of water in a swimming pool and water is filling the pool at a rate of 25 gallons per minute.

Let m = number of minutes

The expression will be:

1600 + (25 × m)

Answer:

Option (2)

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Point A is the midpoint of side XZ and point B is the  midpoint of side YZ.

Triangle XYZ is cut by line segment AB. Point A is the midpoint of side XZ and point B is the midpoint of side YZ. The length of XY is (5x - 7), the length of AB is (x + 1), and the lengths of XA and ZA are (2x - 2). The lengths of YB and BZ are congruent.

What is AX ?

2 units

4 units

6 units

8 units

From the figure attached,

XYZ is a triangle having A and B as the midpoints of the sides XZ and YZ.

By the theorem of midpoints,

AB = [tex]\frac{1}{2}\text{(XY)}[/tex]

Since AB = (x + 1) and XY = (5x - 7)

(x + 1) = [tex]\frac{1}{2}(5x-7)[/tex]

2x + 2 = 5x - 7

5x - 2x = 2 + 7

3x = 9

x = 3

Therefore, side AB = 3 + 1 = 4 units

Side XY = (5x - 7)

             = 15 - 7

             = 8 units

Side XA = 2(x - 1)

              = 4 units

Therefore, Option (2) will be the answer.

Answer:

y ----> the total cost

we know that

Observing the table

1) For the interval of x equal to ----> [0,12]  (close circle both points)

The domain is all whole numbers greater than or equal to 0 visits and less than or equal to 12 visits

The value of y is

y=5x+15

For x=0 ----> y=$15

For x=12 ----> y=5(12)+15=$75

The range is the interval ----> [15,75] (close circle both points)

All real numbers greater than or equal to $15 and less than or equal to $75

2) For the interval of x equal to ---->(12,16] (open circle at left and close circle at right)

The domain is all whole numbers greater than 12 visits and less than or equal to 16 visits

The value of y is

y=4x+32

For x=12 ----> y=4(12)+32=$80

For x=16 ----> y=4(16)+32=$96

The range is the interval ----> (80,96] (open circle at left and close circle at right)

All real numbers greater than $80 and less than or equal to $96      

3) For the interval of x equal to ---->(16,24] (open circle at left and close circle at right)

The domain is all whole numbers greater than 16 visits and less than or equal to 24 visits

The value of y is

y=3x+42

For x=16 ----> y=3(16)+42=$90

For x=24 ----> y=3(24)+42=$114

The range is the interval ----> (90,114] (open circle at left and close circle at right)

All real numbers greater than $90 and less than or equal to $114

The graph that represents the total monthly cost at the gym as a function of the number of visits in a month is shown by option A)

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Based on the number of visits each month, a gym provides three different levels of membership.

Let the monthly visits be 'a' and the overall expense be 'b'. The following will be the appropriate graph showing the total monthly cost of the gym as a function of monthly visits:

A) For the interval of a = [0,12]

The value of b is given by:

b = 5a + 15

when a = 0 in the above equation.

b = $15

when a = 12 in the above equation.

b = 60 + 15

b = $75

The interval of b = [15,75]

B)

For the interval of a = [12,16]

The value of b is given by:

b = 4a + 32

when a = 12 in the above equation.

b = 48 + 32

b = $80

when a = 16 in the above equation.

b = 64 + 32

b = $96

The interval of b = [80,96]

C)

For the interval of a = [16,24]

The value of b is given by:

b = 3a + 42

when a = 16 , we get

b = 48 + 42

b = $90

when a = 24 in the above equation , we get

b = 72 + 42

b = $114

The interval of b = [90,114]

Hence , the graph is represented by graph A

Answer: 48 minutes

Step-by-step explanation:

If there are 7 people painting 7 walls, we can assume that 1 person is painting 1 wall. Altogether they can each paint in 48 minutes.

If there are 20 people painting 20 walls, it would also equal 48 minutes because each person can paint in that time.

Answer:

137 minutes.

2 hrs and 17 minutes

Step-by-step explanation:

The painting of each wall takes 6.85 minutes.

48 / 7 = 6.85.

therefore if there are 20 walls, it must take 20 people 2 hrs and 17 mins

20 x 6.85 = 137minutes.

Step-by-step explanation:

Because the addition property of equality is: The property stating that adding the same number to both sides of an equation does not change the equation.

Equations are used to represent equal expressions

The equivalent equation of y + 4 = 100 is 4 + y = 100

The equation is given as:

y + 4 = 100

Rewrite the equation as follows:

4 + y = 100

Answer:

The confidence interval that is likely to contain the percent of all students nationwide who are only children is (0.1505,0.2554)

Step-by-step explanation:

Total number of students = n = 226

We are given that 20% reported being "only" children (no siblings).

Number of students being "only" children (no siblings) [tex]= 20\% \times 226=\frac{20}{100} \times 226=45.6\sim46[/tex]

So, x = 46

[tex]p=\frac{x}{n}=\frac{46}{226}=0.203[/tex]

Z at 95% is 1.96

Formula for confidence interval for sample proportion :

[tex]CI=p \pm Z \times \sqrt{\frac{p(1-p)}{n}}[/tex]

Substitute the values in the formula :

[tex]CI=0.203 \pm 1.96 \times \sqrt{\frac{0.203(1-0.203)}{226}}\\CI=(0.1505,0.2554)[/tex]

Hence  the confidence interval that is likely to contain the percent of all students nationwide who are only children is (0.1505,0.2554)

Answer:

[tex]w=8cm\\h=18.75cm[/tex]

Step-by-step explanation:

Let:

[tex]w=Width\\h=Initial\hspace{3}height\\h_m=Modified\hspace{3}height\\\\Where:\\\\h_m=h-3[/tex]

The area of the cardboard can be calculated using the formula to find the area of a rectangle:

[tex]A=w*h[/tex]

The area of the new cardboard would be:

[tex]A=w*h_m\\\\Where:\\\\w=8\\h_m=h-3\\A=126[/tex]

So:

[tex]126=8*(h-3)\\\\126=8h-24[/tex]

Solving for h:

[tex]126+24=8h\\\\150=8h\\\\h=\frac{150}{8} =\frac{75}{4} =18.75cm[/tex]

Therefore, the dimensions of the initial cardboard are:

[tex]w=8cm\\h=18.75cm[/tex]

Translation:

Sea:

[tex]w=Ancho\\h=Altura\hspace{3}inicial\\h_m=Altura\hspace{3}modificada\\\\Donde:\\\\h_m=h-3[/tex]

El área de la cartulina se puede calcular usando la fórmula para encontrar el área de un rectángulo:

[tex]A=w*h[/tex]

El área de la nueva cartulina sería:

Entonces:

[tex]126=8*(h-3)\\\\126=8h-24[/tex]

Resolviendo para h:

[tex]126+24=8h\\\\150=8h\\\\h=\frac{150}{8} =\frac{75}{4} =18.75cm[/tex]

[tex]? cup of sugar=1 cup of flour[/tex]

so crisscross them and finally you'll get

1/3*4/3=4/9

For 1 cup of flour, 4/9 cups of sugar is needed.

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -

A : B ∷ C : D

AND

A x D = B x C

Product of extremes equal to product of means.

Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.

Now -

For 1/3 cup of sugar = 3/4 cup of flour is needed.

For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.

Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.
