Answer:
a) We are given the length of both legs. We need to find the hypotenuse.
b) 40^2 + 71.5^2 = X^2
c) 40^2 + 71.5^2 =
1600 + 5,112.25 = 6,712.25 in.
d) 6,712 inches
Step-by-step explanation:
Answer:
59.7%
Step-by-step explanation:
A of Circle = 50.24 sq. inches
A of Rectangle = 30 sq. inches
30 ÷ 50.24 × 100 = 59.71%
Not so sure though
Answer:
1st problem: b) 
2nd problem: c) 
Step-by-step explanation:
1st problem:
The formula/equation you want to use is:

where
t=number of years
A=amount he will owe in t years
P=principal (initial amount)
r=rate
n=number of times the interest is compounded per year t.
We are given:
P=2500
r=12%=.12
n=12 (since there are 12 months in a year and the interest is being compounded per month)

Time to clean up the inside of the ( ).


----------------------------------------------------
2nd Problem:
Compounded continuously problems use base as e.

P is still the principal
r is still the rate
t is still the number of years
A is still the amount.
You are given:
P=2500
r=12%=.12
Let's plug that information in:
.
If this were to be graphed, the independent variable would be the price of the ticket for the rides. The dependent variable would be the total cost.
The fair admission is not a variable because it is a constant price for every single person who goes into the fair.
The problem asks to use y to represent the total cost and x to represent the number of ride tickets. In order to fully write out the equation, we have to figure out what the fair admission costs.
43.75 = 1.25(25) + b
*b represents the fair admission
Multiply 1.25 by 25
43.75 = 31.25 + b
Subtract 31.25 to find what b costs.
12.50 = b
The fair admission costs $12.50.
Solution: y = 1.25x + 12.50

use pythagoeron theorem
9^2-7^2=x^2
x^2=32
x=4
