It would take her 45 mins to grade 2 stacks or 3/4 of an hour.
The value at the end of the year is 100% - 20% = 0.80 of the value at the beginning of the year. After 4 years of multiplying by this factor, the value is
$17,500·0.80⁴ = $7,168
No her estimate is to low because if you multiply 15.5 by 12 you get 186
Answer:
base of the triangle = 12 m
Explanation:
Area of the triangle = 1/2 * base * height
We are given that:
area = 54 m^2
height = 9 m
Substitute in the equation to get the base as follows:
Area of the triangle = 1/2 * base * height
54 = 1/2 * base * 9
108 = 9*base
base = 12 m
Hope this helps :)
76.
If the number after the decimal is below five, you round down. If the number is above five, you round up. 76 is your answer.
