Answer:
12.32 gallons
Step-by-step explanation:
for 14 gallons,
each gallon weighs 8.345 pounds,
therefore 14 gallons =
14 X 8.345
= 116.83 pounds.
14 pounds draining from the tank,
116.83 - 14
102.83 pounds.
to calculate number of gallons remaining,
102.83/8.345
= 12.32 gallons.
Answer:
Step-by-step explanation:
Information that we know about the square:
side length: which can asol be expressed as:
we can use this information to calculate the area by the formula for the area of a square:
we subtitute the side length:
the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:
The exact value of the area of the square is
These questions can be daunting at first, but they're pretty simple to solve.
First, we need to establish a common denominator. We have 2 / 3, 1 / 4, and
-4 / 3. The least common denominator we can get is by multiplying 4 and 3 together to get 12. So we will change the denominator as follows;
2 / 3, 1 / 4, -4 / 3 = 8 / 12, 3 / 12, -16 / 12
Now we can put these back into the equation.
8/12x + 3/12 = -16/12
8x + 3 = -16
It's simple math from here on out, but I'll show the process. What we can basically do now is take away the denominator because it doesn't matter now that it's common.
Subtract 3 from both sides. Now we have 8x = -19
Dividing by 8 on both sides of the equation will get you your answer.
x = -19/8
Hope this helps!
