A certain ride at an amusement park requires that children be at least 50 inches tall but no more that 65 inches tall. Which of the following absolute values best represents this restriction, where h represents height?
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.
Also, I just did it.

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

There are some people in a cinema.
3/5 of the people in the cinema are children
For the children in the cinema,
Number of girls:number of boys = 2:7
Their are 170 girls in the cinema
Work out the number of adults
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]

10 miles ² = blank amount of feet ²
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.

Which equation represents a proportional relationship? Oy=2(x + 1) Oy=2 o y = 4x + 3 o y = 32x y
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
What is a proportional relationship?A proportional relationship usually has the form:
y = kx
Where:
y = dependent variable k = constant of proportionality x = independent variableIn this equation: y = 32x
y = dependent variable 32 = constant of proportionality x = independent variableTo learn more about proportional relationship, please check: https://brainly.com/question/1266676

Sum of the radius of the base and height of a cylinder is 21 cm and the curved surface area of the cylinder is 616 sq.cm,find the total surface area of the cylinder.
Please help me!
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.

Please answer this correctly without making mistakes
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

What is the perimeter of this triangle?
(-4,5)
(8,5)
(8,-4)
A. 36 units
В.
39 units
33 units
D
42 units
Answer:
Perimeter of triangle = 12 + 9 + 15
= 36 units
Therefore, option A is correct.
Step-by-step explanation:
The given points
(-4, 5)(8, 5)(8, -4)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.

A nursery owner buys 9 panes of glass to fix some damage to her greenhouse. The 9 panes cost $22.95. Unfortunately, she breaks 2 more panes while repairing the damage. What is the cost of another 2 panes of glass?
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! :)
