Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Well actually depending on the size, if a small one I would use liters, but if a large ones like Olympics I would use kilolitres.

V = l X w X h
V = 12 X 20 X 14
12 X 7 = 84
84 X 2 = 168
168 X 20 = 3360
The volume of the cooler is 3,360 in³
First of all, to simplify a number/fraction, you must find a common multiple.
Both 12 and 42 is divisible by 6
=
since 6 goes into 12, two times and goes into 42, 7 times. The answer is
when simplified.
Answer:
5:6
Step-by-step explanation:
To find the ratio of side lengths you need to cube root of the ratio of the volumes. The reason you use the cube root is because you are multiplying 3 things together when you find volume.
![\sqrt[3]{\frac{125}{216} } =\frac{5}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B125%7D%7B216%7D%20%7D%20%3D%5Cfrac%7B5%7D%7B6%7D)
5 : 6
