Answer:
a. 53.68
b. 53.53
Step-by-step explanation:
a. Step 1: Approximate the value for :
Since is close to (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.
The expression becomes 6(7.9)+2π
Step 2: Approximate the value for 2π
Since π is approximately 3.14, 2π is approximately 6.28.
The expression becomes 6(7.9)+6.28
Step 3: Use order of operations
6(7.9)+6.28=47.4+6.28=53.68
b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value
The approximation 53.68 is decently close to the actual value, so no minor math errors were made.

Answer:
m=17
Step-by-step explanation:
$15 minus $0.14(# minutes) = $12.62
15 - .14m = 12.62
.14m = 15 - 12.62
.14m = 2.38
m = 2.38/.14
m = 17 minutes
Answer:
The amount of money is 60$
Step-by-step explanation:
Given, Principal, P = $40
Rate, R = 10%
Time, T = 5 years
We have to calculate the amount A = S.I + P
⇒
= 20
Hence, Amount = S.I + P
= 20 + 40 = 60$
