Circumference = 2πr = 27 cm
= 2 × 3.14 × r = 27
= 3.14 × r = 27/2
so, r = [tex]\frac{27}{2}[/tex] × [tex]\frac{1}{3.14}[/tex] = 4.2 cm
I don’t understand this at all please help

A hoodie is on sale for $48. This sale price is 80% of the original price. What was the original price of the hoodie?
Answer: 60 dollars
===============================================
Work Shown:
x = original price
y = sale price
The sale price is always smaller than the original price, so y < x.
The equation linking the two variables is
y = 0.8x
since 80% = 80/100 = 0.8
We know the sale price is $48, which means y = 48. This leads to:
y = 0.8x
0.8x = y
0.8x = 48
x = 48/0.8
x = 60
The original price was $60
Note: since the sale price is 80% of the original price, this must mean that we have a 20% discount (100% - 80% = 20%)
I need help with number 5, and 6.
Please and thank you.
Answer:
5 - 1 year
6 - 738.92
Step-by-step explanation:
5: 260 = 250(1.04)^t
Divide both sides by 250, and we get 1.04. So t must be 1.
6: x + 45 = x(1.03)²

Step-by-step explanation:
Determine which function has a greater change of rate.
Be sure to show work as well.
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change

What's the square root of 64 times 3
Answer:
24
Step-by-step explanation:
Answer:
About 13.86
Step-by-step explanation:
64 x 3 = 192
[tex]\sqrt{} 192[/tex] = 13.8564064606
If you were asking what [tex]\sqrt{64}[/tex] multiplied by 3 was, that answer would be 24. I read it as if you were asking what [tex]\sqrt{64 x 3}[/tex] is. :)

Answer:

Step-by-step explanation:
We are asked to find a slope whilst given a graph.
To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.
So based on what I see, I can see (1, 1) and (2, 5).
The rise over run is as followed :
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
2 and 1 meaning the first and second number within the coordinate, so substitute :
[tex]\frac{5 - 1}{2 - 1}[/tex]
[tex]\frac{4}{1}[/tex]
Divide :
[tex]4[/tex]
4 is our slope.

A car dealership pays $8,350 for a car. They markup the price by 17.4% to get the retail price. What is the retail price of the car at this dealership?
Answer:
I belive its $9,802.9

$8,350 x 0.174 ( 17.4 ÷ 100)
= $1,452.9
$8,350 + $1,452.9 = $9,802.9
