The formula of the surface area of the rectangular prism is equal:
A=2(wl+wh+lh)
where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
A=2\cdot(5\cdot8+5\cdot9+8\cdot9)=2\cdot(40+45+72)=2\cdot157=314\ m^2

How much money would need to be deposited into an account earning 5.25% interest compounded annually in order for the accumulate
scoundrel [369]
Answer provided by our tutors

P = the principal


t = 25 years the time in years


r = 0.0525 or 5.25% annual rate


m = 1 compounding periods per year


i = 0.0525 or 5.25% interest rate per period


n = t*m = 25 total number of compounding periods


A = $75,000 future value


A = P(1 + i)^n


P(1 + i)^n = A


P(1 + 0.0525)^25 = 75000


by solving we find:


P = $20,869.34

A cell phone that regular costs $780 is on sale for 15% off. What is the total cost of the phone if you have to pay 5.5% sales t
Alex_Xolod [135]

Answer:

$700

Step-by-step explanation:

Step one:

Given data

Regular cost of cell phone= $780

discount = 15%

tax = 5.5%

Step two

Let us compute the discounted amount

= 15/100*780

=0.15*780

=$117

hence the selling price is

=780-117

=$663

Also, the tax-deductible is

=5.5/100*663

=0.055*663

=$36.465

The total cost of the phone will be

=663+36.465

=699.465

=$700 to the nearest cent
