Answer:
- A - 4
- B - 1
- C - 3
- D - 2
Step-by-step explanation:
The volume of a given tank is the product of its dimensions. The number of cubic inches in 1 gallon is 231, so dividing the volume by that number converts the volume to gallons. From there, you need to figure what is meant by "the volume of water each can hold."
Tank A holds (36 in)(18 in)(12 in)/(231 in^3/gal) ≈ 33.66 gal. We could describe it as a 30-gallon tank.
Tank C holds (30 in)(12 in)(12 in)/(231 in^3/gal) ≈ 18.70 gal. The nearest offered value is 20 gallons, but we know that tank will not hold 20 gallons.
Apparently we're to choose the nearest available answer, not one that actually makes any mathematical sense. Our choices for the matching are shown above.

In the spreadsheet, the volumes are rounded to the nearest 5 gallons. If we were to go by volume the tank would actually hold, Tank C would be a 15-gallon tank.
Answer:
The first four terms are 3,9,27,81
Step-by-step explanation:
<u>Step :-1</u>
Given first term of sequence is
Given 'n' t h term is .............(1)
here we put n = 2 in equation (1)
..............2
put in equation (2)
put n=3 in equation (1)
put n= 4 in equation (1)
The first four terms of the sequence is
3 , 9, 27 , 81 ....this is geometric sequence
a =3 and ratio term is r =3
