Answer:
Step-by-step explanation:
From the given picture, it can be seen that the diameter of the sphere = 18 inches
Then, the radius of the sphere =
The volume of the sphere is given by :-
The average number of strokes per hole which is hit by the Clare in a round of mini-golf is 3. Clare's statement is correct.
<h3>What is the average of a group of numbers?</h3>
The average of the group of numbers is the ratio of the sum of all the numbers of the group to the total number of the group.
In a round of mini-golf, clare records the number of strokes it takes to hit the ball into the hole of each green.
She said that, if she redistributed the strokes on different greens, she could tell that her average number of strokes per hole is 3.
The sum of all his stroke is,
Here, the total number of stroke she hit is 9. Thus, the average number of strokes per hole is,
Thus, the average number of strokes per hole which is hit by the Clare in a round of mini-golf is 3. Clare's statement is correct.

14/4
Multiply the denominator and the whole number - 4*3=12
Add the numerator - 12+2=14
Put the answer over the denominator 14/4
Answer:
(There's actually a few ways of solving this, but here's one)
Multiplying the second equation by 2.
EDIT: Because the question says it will eliminate a variable "when combined", implying adding the systems together. The actual correct answer is multiplying the second equation by -2.
(multiplying the second equation by -2 is the actual answer, my apologies)
Step-by-step explanation:
So it's clear that they are referring to the elimination method and not the substitution method for solving systems of equations.
In the elimination method, you subtract 2 equations in the hopes of the elimination of a variable.
If you multiply the second equation, 2x + 6y = 24, by 2, you get, 4x + 12y = 48.
This is helpful because when you subtract this from the first one, you eliminate x.
4x + y = 4
-(4x + 12y = 48)
is
-11y = -44
