Answer:
volume of the sphere is V=1766.25 
Step-by-step explanation:
step:1
<u>The volume of the sphere formula is V=
</u>
<u>step:2</u>
Given radius of the sphere r=7.5 ft
substitute given radius r=7.5 ft value in volume of the sphere formula
\\
V=\frac{4(3.14)(7.5)^{3} }{3}[/tex]
V=1766.25 
Final answer is V=1766.25 
Answer:
B. cost(time)
Step-by-step explanation:
In the information given above, you can eliminate choices "A," and "D," since they're just using the cost of a repair and the time the mechanic works. This leaves us with either "B," or "C." The correct answer is "B," because the cost of the repair depends on whatever is inside the parenthesis (the time).
You can use prime factorization to find the GCF of a set of numbers. This often works better for large numbers, where generating lists of all factors can be time-consuming.
Here’s how to find the GCF of a set of numbers using prime factorization:
* List the prime factors of each number.
* Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
* Multiply all the circled numbers.
The result is the GCF.
For example, suppose you want to find the GCF of 28, 42, and 70. Step 1 says to list the prime factors of each number. Step 2 says to circle every prime factor that’s common to all three numbers (as shown in the following figure).
As you can see, the numbers 2 and 7 are common factors of all three numbers. Multiply these circled numbers together:
2 · 7 = 14
Thus, the GCF of 28, 42, and 70 is 14.
