A is correct.
Why? After opening the brackets we can see the equation as
Answer:
15
Step-by-step explanation:
Pythagorean theorem states that the hypogenous of a right triangle is
. The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.
a = 9
b = 12
so,

The equation for decreasing a price by 20% is
original price x 0.8 = sale price
Here, we can fill in the sale price so
original price x 0.8 = 51.44
This can be rearranged to show:
51.44 ÷ 0.8 = original price
So the original price was $64.30
Answer = B - $64.30
Answer:1/16
Step-by-step explanation:1/4= .25
Divide .25 by 4( for the four students) = .0625
.0625 is equivalent to 1/16
Answer:
146°
Step-by-step explanation:
Blue angle: 34°: 180 (sum of angles in a triangle) - 92 - 54 = 34
x = 180 (flat angle) - 34 = 146°
