Answer:
2.5 seconds since the first ball was hit.
Step-by-step explanation:
The equations that model the heights are:
When the balls meet, both heights are equal, therefore:
-16t² + 56t = -16t² + 156t - 248
-16t² + 56t + 16t² - 156t + 248 = 0
- 100t + 248 = 0
248 = 100t
248/100 = t
t = 2.48 ≈ 2.5
First, let’s find how much she spent on monthly operating costs.
5250-4500=750
Then, because all 5 months have been consistent, we can divide by 5
750/5=150
The answer is C
Surface area is area you get from a shapes net.
A net is an unfolded 3d shape.
To find the surface area you use the equation
For this cylinder, the answer would be around 659.73
23) 17/30
41) 3/10 because 3/10 + 7/10 = 10/10 or 1.
