Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V = (3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 = (3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
1. A 1.0 minute
Range can be calculated by subtracting 3.0 mins - 2.0 mins = 1.0 minute.
2. D. 4
Joel was faster than Gunner in meets 1, 2, 3 and 4.
3. B. 1.75 minutes
Gunner has consistent improvement at intervals of 0.25 minutes per meet. Subtracting 2.0 mins by 0.25 mins we get 1.75 minutes.
What is the number? With out the number, I don’t know
Answer:
Step-by-step explanation:
Let x represent the amount invested at 6%. Then the amount invested at 12% is 4x+249. Sherrie's interest is ...
0.06x +0.12(4x +249) = 988.92
0.54x + 29.88 = 988.92
0.54x = 959.04
x = 959.04/0.54 = 1776
4x+249 = 7353
__
Sherrie invested $1776 at 6% and $7353 at 12%.
7/8 is closest to 1 and 4/9 is closest to 0
