If she jogs 1/2 miles in 1/10 hours, we need to find how much she jogs in 1 hour. Since the amount of time (1/10h) went up 10 times (10 * 1/10 = 1) then the distance must’ve also increased 10 times (since time and distance are proportional — the more time she jogs, the more distance she covers) and since 10 times 1/2 is 10/2, which is 5, then we can say she jogs 5 miles per hour.

In the figure above, square ABCD and triangle EFG have the same areas. If AB =6 and EG =8, what is the height o triangle EFG?
lawyer [7]

Answer:

The height of triangle EFG is 9 units

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the area of a square ABCD

The area of a square is equal to

A=b^2

where

b is the length side of the square

we have

b=AB=6\ units

substitute

A=6^2=36\ units^2

step 2

Find the height of triangle EFG

The area of triangle EFG is equal to

A=\frac{1}{2}(b)(h)

where

b is the base of triangle

h is the height of triangle

we have

b=EG=8\ units

A=36\ units^2 ---> area of triangle EFG is the same that the area of square ABCD

substitute the given values in the formula

36=\frac{1}{2}(8)(h)

solve for h

36=4h\\h=9\ units

therefore

The height of triangle EFG is 9 units
