To find the unit rate of the rain per hour, we do:
3÷6= 0.5
So, the unit rate is 0.5 inch of rain/hour
Sum of an irrational number and a rational number is always irrational. Take for example 1/2 +

. Clearly, 1/2 is rational and its decimal expansion is equal to 0.5, while

is irrational and has a non-repeating, non-terminating decimal expansion. When you add the two, you are obviously going to get a non-repeating, non-terminating decimal expansion, hence the sum is irrational.
108 x 100/75 = 108 x 1.25 = 144
108 is 75% of 144.

3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
Answer:
171
Step-by-step explanation:
Multiply the time by how many copies per minute; 45 seconds is equal to 3/4 of a minute, or 0.75:
4.75 x 36 = 171
171 is your answer
Hope this helps!
