Answer: 5
Step by step:
Take 72-27=45
then 45/9=5
First, subtract 18 from 21.96.
21.96 - 18 = 3.96
That is the amount it was increased by.
Now, to find the percent increase, divide 3.96 by 18.
3.96 ÷ 18 = 0.21444
In percents, that is equal to 21.444%.
The large fruit smoothie is 21.444% larger.

Step-by-step explanation:
the scaling ratio is 12/20 = 3/5.
this always applies only to one-dimensional distances, lengths.
the perimeter is calculated as the sum of individual lengths. so while each length is scaled by the same ratio, also the sum is then scaled by that ratio.
p_old = a + b + c
p_new = ra + rb + rc = r(a + b + c) = r×p_old
so, the ratio for the perimeter is also 3/5.
for the area this is a bit different, as an area is always calculated by multiplying 2 lengths (other unscaled factors can be ignored for that consideration of relative change), and that means the scaling ratio has to be multiplied in twice.
a_old = a × b
a_new = ra × rb = r² × a×b = r² × a_old
so, the ratio for the area is
(3/5)² = 9/25
Answer:
See, this is what i do not get. equations like this. People now in days would just by faster internet speed. Why would we need to know this if we will never ever get to use this in our life. Also you could just call the internet cable person. This makes absolutely no since at all. Also who even uses Netflix anymore?
