Answer: 810
Step-by-step explanation:
first lets take down the information we were given,
height (h) of the pyramid should be 12 - 9 = 3
base (a) = 9
So we calculate the volume of a square pyramid
V = a²h/3
V = (9² × 3) / 3
v = (81 × 3) / 3
V = 81
now we calculate the volume of the cube using the formula
V = a³
V = 9³
V = 729
NOW to get the volume of the entire figure
we say
volume of square pyramid + volume of cube
81 + 729 = 810
The percentage of deprecation of the car in the third year is 38.59%.
<h3>What is deprecation?</h3>
Depreciation is the decline in the value of an asset as a result of wear and tear.
Deprecation in year 1 = 15%
Deprecation in year 2 = 15% x (100 - 15%) = 12.75%
Deprecation in year 3 = 15% x (85% - 12.75) = 10.84%
Sum of deprecation = 38.59%

Answer:
10 6/8 or 10 3/4
Step-by-step explanation:
Calculate out how many times the denominator goes into the numerator. To do that, divide 86 by 8 and keep only what is to the left of the decimal point:
86 / 8 = 10.7500 = 10
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
86 - (8 x 10) = 6
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
10 6/8
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 86/8 as a Mixed Number is:
10 3/4
I hope I helped! :) :) :)
