In calculating
the average score, add the scores of each person and then divide it by the
number of scores present. In this problem, Tony has forty seven points for five
different quizzes. You are required to calculate for the average score of Tony.
The formula is A = T/n, where A is the average score, T is the score, and n is
the number of quizzes.
A = T/n
A = 47/5
<u>A = 9.4</u>

Therefore, Tony has an average of 9.4 points in five different
quizzes. </span>

The side length of the square concrete slab if the area is increased by 25% is 5feet
The formula for calculating the area of a square is expressed as:
A = L² where:
L is the side length of the square
Given the area of the square concrete slab = 20 square feet
20 = L²
L =√20
If the area is increased by 25%, new area will be:
An = 20 + (0.25*20)
An = 20 + 5
An = 25 sq.ft
Get the new length
An = Ln²
25 = Ln²
Ln = √25
Ln = 5feet
Hence the side length of the square concrete slab if the area is increased by 25% is 5feet

Answer:
B)8
Step-by-step explanation:
That is the right answer because when y=12, x=-6
12/-6 = -2
This means that x = y/-2
or y = x * -2
-4 * -2 = 8
