Answer:
138 degrees
Step-by-step explanation:
angle 42 and angle D make a an angle of 180 degrees so inorder to find to D we should subtract 42 from 180
The number of trucks needed is an illustration of rates
The number of trucks needed is 42
<h3>How to determine the number of trucks</h3>
The size of the backfill is given as: 243 CY
A truck can load up to 162 CF
So, the number of trucks needed is calculated as:

Convert CY to CF

Solve

Approximate

Hence, 41 trucks are needed

Answer:80
Assume the number to be 400 for instance,
10% of 400 increased = 400 + ( 10/100 × 400 )
= 400 + 40 = 440
The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
Write the number out:
ex) 2 dots on number 3 so write number 3 twice and etc
3,3,4,5,5,5,6,8,8
find the middle number
5 is the middle number so it’s the median
