Answer:
31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%
33) 0.34 x 100=34%
35) we do the inverse to turn it back into
a decimal which will be 0.36
36) 16.24÷100=0.6424
Answer:
x = 8
Step-by-step explanation:
The sum of the measures of two complementary angles is 90°.
m<C + m<D = 90°
5x + 7x - 6 = 90
12x = 96
x = 8

Kindly check explanation
Step-by-step explanation:
Given that:
Cost of owning and operating a printer :
Purchase Cost = $100
Printing per per page = $0.05
Thus, owning and operating cost :
Purchase cost + (Printing per page * number of pages)
Number of pages = p
100 + 0.05p
Service cost :
Amount per page = 0.25
Total revenue = cost per page * number of pages
Total revenue from service =. 0.25p
The equation :
100 + 0.05p = 0.25p ; is the owning and operating cost = total revenue
It gives the equation to calculate the number of pages at which total revenue equals owning and operating cost.
100 + 0.05p = 0.25p
100 =0.25p - 0.05p
100 = 0.20p
p = 100/0.2
p = 500
When number of pages equals 500; the owning and operating cost is equal to the revenue made.
