Answer:
90 meters squared
Step-by-step explanation:
First you multiply 10*4.5=45
Then you multiply 45 and 2 because 1cm=2m
45*2=90
Given that the book value of the automobile that was purchased is 30,000 and is to be depreciated for 3 years using MACRS method of depreciation the value of the automobile at the end of the year is 8,640 dollars. This is computed by summing up the depreciation for the firswt 3 years which is equal to 71.2 per cent less 100 then it will be multiply to 30,000.
Answer:
x = y²
Step-by-step explanation:
Given
x =
and y = 
Note that
x =
=
×
= y²
Thus x = y²
For the first one, to find x, you are going to take that entire side which would equal to 180 and solve. 2x+20+55=180 would then go down to 2x+65=180 once you add the 20 and 55. Then subtract 65 to both sides and divide your final answer 115/2 which is x=57.5. For the second one it’s 4x-2+21=180, then you will subtract 2 from 21 and get 19. After you would subtract 19 by 180 and divide 4 by each side, getting x=40.25 as your final answer.
Answer:
Use the Pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is
where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:

Simplify the equation to get:

Add 16 and 9 to get 25 and take the square root of both sides:

The sqrt of 25 is 5. Therefore, the length of the hypotenuse, or c, is 5.
