The Associative Property allows you to "regroup" addition and multiplication problems. You can group this problem in two other ways,
(8 + 4) + 3 and (8 + 3) + 4.

Step-by-step explanation: ¯\_(ツ)_/¯
Answer:
The circle length is 90*pi which should be 3.14
So the circle length is 282.6
The central angle is 90 degree which is 1/4 part of 360 degree
From the theory of arc, the arc length should also be 1/4 part of circle length.
So the answer should be 1/4 * 282.6 = 70.65
Becasue it should be to the nearest tenth, so the answer should be 70.7
Step-by-step explanation:
It will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
<h3>How to determine the time to hit the ground?</h3>
The function is given as:
h = –.025t^2 + 4t + 50
Set h = 0.
So, we have:
–.025t^2 + 4t + 50 = 0
Using a graphing calculator, we have:
t = -11.652 and t = 171.652
Time cannot be negative.
So, we have:
t = 171.652
Hence, it will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
