Step-by-step explanation:
This represents exponential decay
Answer:
256 degrees.
Step-by-step explanation:
The figure is a parallelogram so m < 1 = 180-52 = 128 degrees (same side angles).
Also m < 2 = m < 1 (opposite angles of a parallelogram), so their sum is 2*128
= 256 degrees.

Multiply
by 80 and you will get how many boys play video games daily.

44 is the number of boys who play video games daily.
40/3 days, (13.33 days)
Step-by-step explanation:
Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.
10 * 20 = 15x, x = 200/15 = 40/3
Why?
b/c if each pig eats the same amount of food, then the ratio between the number of pigs and days should remain constant.
