Answer:
73
Step-by-step explanation:
to find the mean you need to add up all grades and divide if by the number of terms you added
(82 + 88 + x) ÷ 3 = 69 (since we don't know the third grade let's call it x)
170 + x = 69 × 3
x = 37
if the digits transposed the the actual grade would be 73
The answer is 5 3/4.............
It is right but what's the full question
- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°
Step-by-step explanation:
Calculate the the total number of the boxes. We can calculate it by counting number of the rows and the number of the columns and then multiplying it.
Total number of rows = 10
Total number of columns = 10
Total boxes = 100
Shaded boxes = 72
We calculate %age by,
=> Selected boxes/Total boxes x 100
=> 72/100 x 100
=> 72%
