c.9 3/8
d.3 6/20

Answer:

|h-57.5| less than or equal to 7.5

Step-by-step explanation:

Since the question states that a child must be 50 and 65 inches, plug in values that are within this range and determine which answer choice gives a TRUE relationship. Choose 60 for h.

Answer:

$5.10 For the 2 extra panes

Step-by-step explanation:

So 9 pained are 22.95

22.95/9=2.55

Since 2 panes are broken

2.55*2

that is 5.1

or $5.10

Answer:

$5.20

Step-by-step explanation:

First, we need to work out how much 1 pane is.

So $22.95÷9=$2.55

Then you times it by 2

So $2.55×2=$5.20

I hope this helps! :)

Answer:

1st option, (2x, 2y)

Step-by-step explanation:

If we select any random point on Figure S, let's just say the upper right hand corner of the arrow at (2,3), and compare that to the same point but on Figure T, it is now (4,6). By just looking at the two points, we can see that the x and y values of the point we chose from Figure S had to be doubled to get to that point but in Figure T

Answer:

[tex]y=\frac{1}{2} x-8[/tex]

Step-by-step explanation:

Slope-intercept form is organized in the form y=mx+b, where m is the slope and b is the y-intercept.

Because we're already given the values, we just have to plug them into the equation.

[tex]y=mx+b\\y=\frac{1}{2} x+(-8)\\y=\frac{1}{2} x-8[/tex]

To graph this equation, first plot a point at (0, -8). This is because the y-intercept is -8, meaning that the line crosses the y-axis when y=-8.

Then, plot the next point using the slope. The slope is equal to the rise/run of the line, or the number of units the line travels upwards / the number of units the line travels to the right. Because the slope is 1/2, we know that for every 2 units a point travels to the right, it goes up by 1 unit.

Answer:

1213 tablespoons

1 teaspoon

Step-by-step explanation:

This answer is my interpretation of what the question is asking, it could be wrong.

This question says, one has 2426 tablespoons, and 2 teaspoons of a substance. If one were divided that quantity in half, how much of that substance could they have. So essentially, all one needs to do is divided 2426 by 2, and divide 2 by 2.

2426 ÷ 2 = 1213

2 ÷ 2 = 1

Answer:

25% change

Step-by-step explanation:

(15 - 12) / 12 = 3/12 = 1/4 = 0.25

Answer:

Step-by-step explanation:

To convert square miles to square feet, multiply the square mile value by 27878400. For example, to convert 10 square miles to square feet, multiply 10 by 27878400, that makes 278784000 sq ft is 10 sq mi.

Answer:

y=32x shows a proportional relationship.

Step-by-step explanation:

We need to find an equation that shows the proportional relationship.

If x and y are proportional to each other, it will look like,

y = mx

Where

m is constant of proportionality

Out of 4 option, option (4) is y=32x, it shows the proportional relationship where the value of m is equal to 32.

The equation that represents a proportional relationship is y = 32x

A proportional relationship usually has the form:

y = kx

Where:

In this equation: y = 32x

Answer:

[tex]Adults = 510[/tex]

Step-by-step explanation:

Given

[tex]Children = \frac{3}{5}[/tex]

[tex]Girls:Boys = 2 : 7[/tex]

[tex]Girls = 170[/tex]

Required

Determine the number of adults

First, we need to calculate the number of children

[tex]Girls:Boys = 2 : 7[/tex]

Given that: [tex]Girls = 170[/tex]

Substitute 170 for Girls in [tex]Girls:Boys = 2 : 7[/tex]

[tex]170 : Boys = 2 : 7[/tex]

Convert to fraction

[tex]\frac{170}{Boys} = \frac{2}{7}[/tex]

Cross Multiply

[tex]Boys * 2 = 170 * 7[/tex]

Divide both sides by 2

[tex]Boys = \frac{170 * 7}{2}[/tex]

[tex]Boys = \frac{1190}{2}[/tex]

[tex]Boys = 595[/tex]

So, the number of children are:

[tex]Children = Boys + Girls[/tex]

[tex]Children = 595 + 170[/tex]

[tex]Children = 765[/tex]

Next, we calculate the number of people in the cinema.

[tex]Children = \frac{3}{5} * People[/tex]

Substitute 765 for Children

[tex]765 = \frac{3}{5} * People[/tex]

Make People the subject.

[tex]People = \frac{765 * 5}{3}[/tex]

[tex]People = \frac{3825}{3}[/tex]

[tex]People = 1275[/tex]

If 3/5 are children, then 2/5 are adults.

So:

[tex]Adults = \frac{2}{5} * 1275[/tex]

[tex]Adults = \frac{2* 1275}{5}[/tex]

[tex]Adults = \frac{2550}{5}[/tex]

[tex]Adults = 510[/tex]

Given:

Sum of the radius of the base and height of a cylinder = 21 cm

Curved surface area of the cylinder = 616 sq.cm

To find:

The total surface area of the cylinder.

Solution:

Let r be the radius of the base and h be the height of the cylinder.

Sum of the radius of the base and height of a cylinder = 21 cm

[tex]r+h=21[/tex]

[tex]h=21-r[/tex]           ...(i)

Curved surface area of the cylinder is

[tex]CSA=2\pi rh[/tex]

Curved surface area of the cylinder = 616 sq.cm

[tex]2\pi rh=616[/tex]

[tex]2(\dfrac{22}{7})r(21-r)=616[/tex]

[tex]44r(21-r)=616\times 7[/tex]

[tex]21r-r^2=\dfrac{616\times 7}{44}[/tex]

[tex]21r-r^2=14\times 7[/tex]

[tex]0=98-21r+r^2[/tex]

[tex]0=98-14r-7r+r^2[/tex]

[tex]0=14(7-r)-r(7-r)[/tex]

[tex]0=(7-r)(14-r)[/tex]

[tex]r=7,14[/tex]

Using (i), for r=7, h=14 and for r=14, h=7.

Total surface area of the cylinder is

[tex]A=2\pi r(r+h)[/tex]

For r=7 and h=14,

[tex]A=2(\dfrac{22}{7})(7)(7+14)[/tex]

[tex]A=44(21)[/tex]

[tex]A=924[/tex]

For r=14 and h=7,

[tex]A=2(\dfrac{22}{7})(14)(14+7)[/tex]

[tex]A=88(21)[/tex]

[tex]A=1848[/tex]

Therefore, the total surface area of the cylinder is either 924 sq.cm or 1848 sq. cm.

Answer:

Perimeter of triangle = 12 + 9 + 15

                                   = 36 units

Therefore, option A is correct.

Step-by-step explanation:

The given points

From the table, it is clear the side containing the line segment joining the points (-4, 5) and (8, 5) is a straight horizontal line.

Thus, the length of the horizontal distance from the points (-4, 5) and (8, 5) will be:

8-(-4) = 12 units

From the table, it is clear the side containing the line segment joining the points (8, 5) and (8, -4) is a straight vertical line.

Thus, the length of the vertical distance from the points (8, -4) and (8, 5) will be:

5-(-4) = 9

Now, finding the length of the side containing the segment (8, -4) and (-4, 5) using the formula:

[tex]\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]=\sqrt{\left(-4-8\right)^2+\left(5-\left(-4\right)\right)^2}[/tex]

[tex]=\sqrt{\left(-4-8\right)^2+\left(5+4\right)^2}[/tex]

[tex]=\sqrt{12^2+9^2}[/tex]

[tex]=\sqrt{144+81}[/tex]

[tex]=\sqrt{225}[/tex]

[tex]=\sqrt{15^2}[/tex]

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]

[tex]=15[/tex]

We know that the Perimeter of a rectangle is the length of all the sides of the triangle. Therefore, combining all the lengths of the line segments

Thus,

Perimeter of triangle = 12 + 9 + 15

                                   = 36 units

Therefore, option A is correct.
