Since it's a regular pentagon, all it's sides are equal so let's solve for x






now let's find the measure of each side, i.e





perimeter = 5 × side length ( for a regular pentagon )


Answer:
First one: 0.4
Second one: 4
Step-by-step explanation:
We find the cube root of 0.064 which is 0.4
In order to find the length of side s, we just cube root 64 because it is 
Compound interest is given by:
A=p(1+r/(100*n))^(nt)
where;
A=future amount
p=principle amount=$35,000
r=rate=10%=0.1
n=number of terms=2
t=time=6
Hence,
A=35,000(1+0.05)^(2*6)
A=35000(1.05)^12
A=$62,854.97
The amount of money after 6 years will be $62,854.97
Complete question :
Wang Yong owes the bank $8500. To repay the debt, he paid a fixed amount back to the bank each month. After 12 months, his remaining debt was $6460. How much did Wang Yong pay each month?
Answer:
$170
Step-by-step explanation:
Given that:
Amount owed = $8500
Fixed amount replayed per month :
Amount left after 12 months = $6460
Amount paid per month :
Total amount paid over 12 months :
$(8500 - 6460) = $2040
Amount paid per month :
$2040 / 12
= $170
