Sarah's arm if 20 inches long. If Sarah swings her arm in a circle, what will the diameter of the circle be?
Answers
When Sarah swings her arm, she swings from the shoulder which acts as the center of a circle. The length of her arm is the radius of the circle. If her arm is 20 inches long, then the diameter of the circle is twice that or 40 inches.

The cost per book is $3.41 thus the cost of buying 7 books will be $23.87 maintaining the given ratio.
What are the ratio and proportion?
The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
For example, a/b, where a will be the numerator and b will be the denominator.
As per the given,
The book fair had a sale where 6 books were $20.46.
Cost per book = 20.46/6 = $3.41
To buy 7 books,
The cost of buying 7 books at $3.41 per book will be,
⇒ 3.41 × 7 = $23.87
Hence "The cost per book is $3.41 thus the cost of buying 7 books will be $23.87 maintaining the given ratio".

Part B:-while she was a member of the club , susan paid a total of $105.75. how many videos did she rent?
Answers
0.75 per video so
total cost = iniation fee+0.75 times number of videos or
total cost=12.75+0.75 times v
0.75 times v=0.75v so
total cost=12.75+0.75v
if total cost=105.75 then subsitute
105.75=12.75+0.75v
subtract 12.75 from both sides
93=0.75v
multiply both sides by 100 to clear decimal
9300=75v
divide both sides by 75
124=v
she rented 124 videos
A:total=12.75+0.75v
B:124 videos

7 x 7 = 49 area of square.
The radius of the circle is half the diameter. 7 cm/2 = 3.5
A = 3.14 × 3.5 cm × 3.5 cm = 38.465
Finale step. Subtract the area of the circle from the area of the square.
49 cm^2 −38.465 cm^2 = 10.535 or round to 10.54 cm^2
D. 10.54
