Answer:
98
Step-by-step explanation:
Average is the sum of all data points divided the number of data points.
In this specific situation, the average test score, 91, is equal to the sum of Molly's four individual test scores divided by the number of test Molly had, 4.
(( 86 + 87 + 93 + x) / 4) = 91
86 + 87 + 93 + x = 91/4
86 + 87 + 93 + x = 364
x = 364 - 93 - 87 - 86 = 98
Answer:
12 - 4
3 - 1
18 - 6
Step-by-step explanation:
This is simply a matter of pluggin in the method, so let's do it shall we?
It wants you to put the a third of each number, so you'll divide each number by three to get what the third is!
VISUAL REPRESENTATION:
12÷3 = 4
3÷3 = 1
18÷3 = 6
The volume of the cylinder that has a radius of 7 ft and a height of 5 ft in the geometry will be 769.7 ft³.
<h3>How to illustrate the geometry?</h3>
It should be noted that the volume of a cylinder is given as:
= πr²h
where,
π = 3.142
r = radius = 7
h = height = 5
Therefore, the volume will be:
= πr²h
= 3.142 × 7² × 5
= 3.142 × 49 × 5
= 769.7 ft³
