1.717
Step-by-step explanation:
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
Distribute the number 2.
2*2x= 4x
-1*2= -2
4x-2 is the most you can simplify this.
I hope this helps!

Answer:
see the explanation
Step-by-step explanation:
The given rate is

Create three different rates, that are all equivalent to this rate
<u>First rate </u>
1,440 gallons in 3 hours
Find the units rate
Divide the total volume by the total time

<u>Second rate </u>
960 gallons in 120 minutes
Find the units rate
Divide the total volume by the total time
Convert minutes to hours


<u>Third rate </u>
720 gallons in 1.5 hours
Find the units rate
Divide the total volume by the total time

<em>Convert gal/h to gal/min</em>
Remember that
