Answer:
15 gallons
Step-by-step explanation:
So the easiest way to solve this one is basic reasoning. It's easy to find 3/4 of a number if you know what 1/4 is.
20/4 = 5, or 1/4 of 20 = 5
3/4 is 3 times as much as 1/4, so 5(3)=15
Or, you can solve using a proportion
3 x
_ = _
4 20
(those are fractions)
Cross multipy
3 (20) = 4x
60 = 4x
Divide both sides by 4 to isolate the variable
15 = x
The final way to solve this is by converting the decimal to a fraction. 3/4 = 0.75
20 x 0.75 = 15
Answer:
-0.3125
Step-by-step explanation:
Subtract 3.5 from both sides
4t = -1.25
Divide both sides by 4
t =. -0.3125
The angle between the legs of length 16 and 18 has measure 90 + 55 = 145 degrees.
Now use the law of cosines: it says satisfies
and solving for gives
so the answer is C.
You could simply turn them into decimals.
3.4 - 2.8
Which is .6 or as a fraction 6/10 or simplified 3/5
Answer:
your answer is 1
Step-by-step explanation:
when you work with negative numbers, you have to work backwards.
