You're going to set up a proportion. % over 100 = is over of. You're looking for the percent so that's your x. X over 100=7 over 25. Cross multiply to get 25x=700. Divide both sides by 25 and your answer is 28%

A car is traveling at a speed of 81 miles per hour. What is the car's speed in feet per second? How many feet will the car trave
qaws [65]

1 mile = 5280 feet

81 * 5280 = 427680 feet per hour

 1 hour = 3600 seconds

427680 / 3600 = 118.8 feet per second


118.8 * 15 = 1782 feet in 15 seconds

I need help.. with thissss
damaskus [11]

9514 1404 393

Answer:

  7.06

Step-by-step explanation:

This triangle can be solved a couple of ways. In the end, they amount to the same thing.

1) The area is ...

  A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base

Using GE as the base, the height (DF) is ...

  A = (1/2)(17)(DF)

  2(60)/17 = DF = 120/17

  DF ≈ 7.06

__

2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...

  (long side)/(hypotenuse) = DE/GE = DF/DG

  DF = DG(DE/GE) = 8(15/17) = 120/17

  DF ≈ 7.06

15 squares + 15 squares =30  then you times 2.25 times 30 to get 67.5 the you do the other side 11 squares + 11 squares=22 squares then you times 22 squares by 2.25 and you get 49.5 then you add the 67.5+49.5=117
