Answer:
Step-by-step explanation:
1). Let the circumference C and area A of the circle are proportional,
C ∝ A
C = kA
Here k = proportionality constant
k = [tex]\frac{C}{A}[/tex]
From the given table,
For C = 25 cm, A = 50 cm²
Then the value of k = [tex]\frac{25}{50}[/tex]
k = [tex]\frac{1}{2}[/tex]
For C = 50 cm, A = 201 cm²
k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]
In both the cases proportionality constant is giving the different values.
Therefore, Circumference and Area of the circular objects are not proportional.
2). If A = [tex]\frac{1}{2}\times r\times C[/tex]
Then this equation will be true for all the values of r and C given in the table.
For r = 4 cm and C = 25 cm
A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²
For r = 8 cm and C = 50 cm
A = [tex]\frac{1}{2}\times 8\times 50[/tex]
A = 200 cm²
True for all values of 'r' and 'C'.

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?
Answers
Answer: i think it is 46.38 %
Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)
Answer:
38.3%
Step-by-step explanation:
We have two equations to find the answer.
1. Discount = OG Price * Discount by 100%
2. Final Price = OG Price - Discount
So fill in the first equation :
Discount = 28.99 * 38.3/100
Discount = 28.99 * 0.38
Saved = $11.10
Now for the second equation :
Final Price = 28.99 - 11.10317
Final Price = $17.89
Therefore the discount is 38.3%

Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50

What is the slope of this line?
Answers
Answer:
A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .
A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .
If a line is horizontal the slope is zero. This is a constant function.
If a line is vertical the slope is undefined (see below).
