To calculate the volume of a sphere you must use the formula
v=4/3pir^3
The radius (r) is half of the diameter
r=13.5
v=4/3pi13.5^3
v=10305.99
Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)
Answer:
6 miles in 90 minutes
Step-by-step explanation:
Since wendy is walking at a fair constant rate, you would multiply 3x30 to get 90 minutes and you will multiply 2x3 to get 6 miles
Answer:
1. f(x)=x+7
2. f(x)=1.2x
Step-by-step explanation:
1. If f(x+5)=x+12, then substitute
Hence,
Now change t into x:
2. If f(x-5)=1.2x-6, then substitute
Hence,
Now change t into x:
Answer:
Step-by-step explanation:
The top and bottom segments have same length.
a)
- n + n + 19 = 33
- 2n + 19 = 33
- 2n = 33 - 19
- 2n = 14
- n = 14/2
- n = 7
b)
- x + x + x + 3 = 30
- 3x = 30 - 3
- 3x = 27
- x = 27/3
- x = 9
