Initially, 1/4 of the tank was filled.
After adding 12 gallons, it was 3/4 full.
Increase in fuel filled portion =
So 2/4 of the tank = 12 gallons
1/4 of tank = 12 ÷ 2 = 6 gallons
4/4 of tank = 6×4 = 24 gallons
____________________
Portion remaining to be filled =
Fuel needed = 1/4 × 24 = 6 gallons
So you need 6 more gallons to fill the tank
Answer: 80
Step-by-step explanation: multiple b(3) with everything its next to, then add it all up
Considering that the square root of 9 is of 81 and of 10 is of 100, we have that the expression that has a value between 9 and 10 is given by:
B.) √89
E.) ![\sqrt[3]{750}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B750%7D)
F.) ![\sqrt[3]{999}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B999%7D)
<h3>How the square root of a number is used to solve this question?</h3>
We suppose numbers n and m, with square roots given, respectively, by n² and m².
Then, the square roots of all numbers between n² and m² have values between n and m.
In this problem, the square roots are given by:
Hence, the square root of all values between 82 and 99 are values between 9 and 10, thus option B is correct.
As for the cubic root, we apply the same logic and have that:
Hence options E and F are also correct, as the values between 730 and 999 have cubic roots between 9 and 10.
