You mean '39 is what percent of 12.5 ?'
So, the answer is
39/12.5 × 100
= 3.12 × 100
= 312%
So, 39 is 312% of 12.5.
(The percentage is greater because 39 is greater than 12.5)
Answer:
11 11/18
Step-by-step explanation:
Calculate by breaking to wholes and parts
diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )
Answer:
B = 70
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
40 + 2x-30 + x+20 = 180
Combine like terms
3x + 30 = 180
Subtract 30 from each side
3x+30-30 = 180-30
3x = 150
Divide by 3
3x/3 =150/3
x = 50
We want to find angle B
B = 2x-30
=2(50) - 30
= 100 - 30
= 70
