Concept: Area
[tex]area = \pi {r}^{2} [/tex]We are given area hence 78.5 square meters We want the radius so we isolate[tex]78.5 = \pi {r}^{2} [/tex]Isolate for r to get r= 4.99 or 5 square units approximatelyAnswer:
Step-by-step explanation:
use the area of a circle formula
A=pi r^2
78.5= pi r^2
78.5/ pi =r^2
24.9873..=r^2
[tex]\sqrt{24.9873}[/tex] = r
4.9987...=r in meters , pretty close to 5

Which graph represents the function y = x – 2? A coordinate plane with a line passing through (0, negative 3) and (2, 0). A coordinate plane with a line passing through (0, 2) and (2, negative 1). A coordinate plane with a line passing through (0, negative 2) and (3, 0). A coordinate plane with a line passing through (0, 1.5) and about (2.25, 0).
Answers
The graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).
None of the given options is correct
The given equation is:
y = x - 2
Find the x-intercept by making y = 0 and finding the corresponding x-value
y = x - 2
0 = x - 2
x = 2
The line y = x - 2 passes through the point (2, 0)
Also, find the y-intercept by making x = 0 and finding the corresponding y-value
y = x - 2
y = 0 - 2
y = -2
The line passes through the point (0, -2)
Therefore, the graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
Suppose Salesmen A and B have the same number of sales and earn the same amount in Week 4 of this month. How many sales must they both have had?
sales
Answers
Answer: 12
Explanation: x will be the number of sales the sales man had. so this is the equation 65x = 40 +300
65x -40x = 25x
25x = 300 then divide by 25
25 25
x = 12
Choose the statement that tells how the area of the reduced design compares to the area of the original design.
Group of answer choices
The area of the reduced design is the same as the area of the original.
The area of the reduced design is 1/4 of the area of the original.
The area of the reduced design is 1/2 of the area of the original.
The area of the reduced design is 4 times greater than the area of the original.
Answers
The original is 5cm, the reduced is 2.5cm
2.5/5 = 0.5 = 1/2
Area is a square measurement, so the area of the reduced image would be the scale squared, which would be 1/2^2 which = 1/4
The answer is:
The area of the reduced design is 1/4 of the area of the original.

here, we have,
given that,
The scale of a map is 2 in = 7 feet.
so, we get,
if 2=7feet
let, the required distance = x
then, we have,
11=?(x)
