Corresponding sides have the same ratio.
(2a -5)/25 = 18/30
2a -5 = 25*18/30 = 15
a = (15 +5)/2 = 10
(3b +1)/15 = 30/18
3b +1 = 15*30/18 = 25
b = (25 -1)/3 = 8
a = 10
b = 8
Answer:
Step-by-step explanation:
The formula for finding the Volume of a Cylinder is 3.14(pie)r2 (radius squared) multiplied by H (height)
In order to solve this we must first,
Subtract both sides of the equation by 10,
y-10=1/2x
Now we have to multiply both sides by 2 so that only x is left.
2y-20=x
Therefore, x=2y-20
Answer:
13.5 Minutes
Step-by-step explanation:
First you divide 128 by 3 to get the WPM (Words Per Minute) that gets you an average speed of 42.66 WPM so you then divided the total amount of words (576) by 42.66 to get the answer of 13.5 Minutes or to type 576 words.
