Since the steps are the same size, and she ended up where she started, she must have taken the same number of steps forward as she took backward.
16/2 = 8
She took 8 steps forward and 8 steps backward.
The correct answer to this question is that the cheetah can run 369,000
feet per hour. We can work this out in the following way:
One mile equals 1760 yards
In feet that is 3 x 1760 or 5,280
So Feet per hour will be 5280 x 70 or
369,600 feet per hour.
Okay I tried to work it without a picture of the triangle BUT
the answer should be <span>sinB = 0.97752</span>
The correct answer is D.
The area is base x height which in this case is 14 x 8 = 112 which is answer choice D.
Hope this helps.
