A) A = 40m + 300
b) 820 = x12 + 100
x = 60
B = 60m + 109
Answer:
135 square feet.
Step-by-step explanation:
A triangular prism. The rectangular sides are 8 feet by 2.5 feet, 8 feet by 6 feet, and 8 feet by 6.5 feet. The triangular sides have a base of 2.5 feet and a height of 6 feet.
The prism has two triangular faces and three rectangular faces.
So, the surface area of the prism will be
= 15 + 20 + 48 + 52
= 135 square feet. (Answer)

72.5m/hr
Step-by-step explanation:
Divide 870 by 12 to represent how many miles David drove in 1 hour.
David drove 72.5 miles per hour.
First we need to calculate annual withdrawal of each investment
The formula of the present value of an annuity ordinary is
Pv=pmt [(1-(1+r)^(-n))÷(r)]
Pv present value 28000
PMT annual withdrawal. ?
R interest rate
N time in years
Solve the formula for PMT
PMT=pv÷[(1-(1+r)^(-n))÷(r)]
Now solve for the first investment
PMT=28,000÷((1−(1+0.058)^(−4))
÷(0.058))=8,043.59
The return of this investment is
8,043.59×4years=32,174.36
Solve for the second investment
PMT=28,000÷((1−(1+0.07083)^(
−3))÷(0.07083))=10,685.63
The return of this investment is
10,685.63×3years=32,056.89
So from the return of the first investment and the second investment as you can see the first offer is the yield the highest return with the amount of 32,174.36
