Answer:
7) 16 sq units
8) L = 22 cm
Step-by-step explanation:
7) A = 1/2h·(sum of bases)
= 1/2(4)(5+3)
= 2(8) or 16 sq units
8) A (trapezoid) = 1/2(7)(10+12)
= 1/2(22)(7)
= 11(7) or 77 sq cm
To find 'l' in triangle:
A = 1/2·L·7
77 = 7L /2
7L = 154
L = 22 cm
Answer:
420 sq.ft. per hour

Answer:
Principal, P = $23675.90
Step-by-step explanation:
Given the following data;
Interest rate = 2.2 %
Future value = $27000
Time = 6 years
Number of times = 365 days
To find the principal amount, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
Principal, P = $23675.90
