Help please? I can’t figure this out

Step-by-step explanation:

surface area=2×area of trapezoid(front and back)+area of base (rectangle)+area of top (area of two rectangles)+area of side rectangle

surface area=2[(8+6+8)/2×7]+(8+6)×6+(8+9)×6+7×6

=2×77+14×6+17×6+7×6

=154+84+102+42

=382 cm²

front is made of rectangle and a triangle.

together they make a trapezoid with parallel sides 14 (8+6) and 8

area of trapezoid=(sum of parallel sides)/2×length of perpendicular between parallel sides (here 7)

=(14+8)/2×7=77

area of two trapezoids (front and back)=2×77=154 cm²

base contains two rectangles (8×6 and 6×6)

area of base=8×6+6×6=48+36=84  cm²

Top contains two rectangles (8×6 and 9×6)

area of top=8×6+9×6=48+54=102 cm²

area of side rectangle=7×6=42 cm²

Total surface area=154+84+102+42=382 cm²

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
