Answer:
because u just do 3 x 65 then you divide by 10 two times
Step-by-step explanation:
Discussing interest starts with the principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.
Simple One-time Interest
I = P0r
A = P0 + I = P0 + P0r = P0(1 + r)
The equation would be X +21+ 2X +17+ 2X +17 equals 180 when solved you get X equals 25

Answer:
18.73 feets
Step-by-step explanation:
Given that:
Horizontal distance between ground and foot of flagpole = 7 feets
Lenght of wire = 20 feets
The height of the flagpole, h can be obtained using Pythagoras :
Adjacent = sqrt( hypotenus² - opposite²)
Height of flagpole = sqrt((length of wire)² - (horizontal distance between ground and flagpole)²)
Let height of flagpole = h
h = sqrt(20² - 7²)
h = sqrt(400 - 49)
h = sqrt(351)
h = 18.73 feets
