The volume is given as V = Lwh = 20 m^3.
Since the base is a square then V = L²h = 20 m^3
Rearranging, we have L = √(20/h).
For the metal frame:
8√(20/h) + 4h ==> [8 is multiplied to √(20/h) because there are 8 sides measuring L, and 4 is multiplied to h because there are 4 sides that have measure h.]
9[8√(20/h) + 4h]
=72√(20/h) + 36h = Cost of metal frame
For the glass:
Area of one square base = L² = 20/h
Area of one rectangular side = h√(20/h)
Area of 4 rectangular sides = 4h√(20/h)
10[20/h + 4h√(20/h)] = Cost of glass
C = 72√(20/h) + 36h + 10[20/h + 4h√(20/h)]
(take note, we did not multiply 10 to the terms because 10 dollars is per unit area and not unit length.)
12% of 16.50 = 1.98
16.50 + 1.98 = $18.48
Answer:
$17,999.10
Step-by-step explanation:
Let x represent the amount the bank will lend.
x = $19,999(1 -10%) = 0.90($19,999) = $17,999.10
The bank is willing to lend $17,999.10 on the car.
2149 x 25/100 = 537.25
1st year - 214 - 527.25 = 1611.75
2nd year - 1611.75 x 25/100 = 1208.81
3rd year - 1208.81 x 25/100 = 906.60
Ans : 906.60
Answer:
none of the above
Step-by-step explanation:
the answer is -3/4
