Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20
= 62.831 in
Answer:
100
Step-by-step explanation:
Because if 50 percent of x is 50 than x = 100
Answer: The answer is 315.
Answer:
Let n represent the number of months after Tina would save the same amount using either option.
400 + 30n = 100 + 50n
400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality
400 = 100 + 20n Combine like terms.
400 − 100=100 + 20n − 100 Subtraction Property of Equality
300 =20n
300
20
=
20n
20
15 months=n
After 15 months, Tina will save the same amount using either option.
400 + 30(15)=100 + 50(15)
400 + 450=100 + 750
850 = 850
After 15 months, Tina will save $850 with either option.
