Answer:

Step-by-step explanation:

The diameter of each curved path is 200 feet. Since the two curved semi circular paths are equal, they would form a circle. It means that the distance around the two semi circular paths would be the circumference of the circle. Formula for determining the circumference of the circle is π × diameter. It becomes

200 × 3.14 = 628 feet

Total distance around the track would be

300 + 300 + 628 = 1228 feet

5280 feet = 1 mile

1228 feet = 1228/5280 = 0.23 mile

If he runs around the track exactly 15 times, it means that the number of miles covered is

0.23 × 15 = 3.45 miles

Since he will collect $4.50 for every mile he runs, the amount of money that he collected is

4.5 × 3.45 = $15.5

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?

mina [271]

Answer:

The volume of the dilated prism is $86.4ft^3$ .

Step-by-step explanation:

The original prism has base area $5ft^2$ and a height of $10ft$ .

The volume of the original prism is $v=5\times 10=50ft^3$ .

The prism is dilated by a scale factor of $k=\frac{6}{5}$ .

To find the volume of the dilated prism, we multiply the volume of the original prism by $k^3=\frac{216}{125}$ .

$V=\frac{216}{125} \times 50ft^3$

$\Rightarrow V=86.4ft^3$

If M (4.2) is the midpoint of AB and A (-5, -3), find the coordinates of B.

loris [4]

Given:

M(4,2) is the midpoint of AB and A(-5, -3).

To find:

The coordinates of B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

M(4,2) is the midpoint of AB and A(-5, -3).

$M=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)$

$(4,2)=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)$

On comparing both sides, we get

$4=\dfrac{-5+a}{2}$

$8=-5+a$

$8+5=a$

$13=a$

And,

$2=\dfrac{-3+b}{2}$

$4=-3+b$

$4+3=b$

$7=b$

Therefore, the coordinates of point B are (13,7).
