Answer:360
Step-by-step explanation:
-5.8 - (-8.4)
When we multiply two negatives they become a positive. In this situation, where there is no other number, you can assume there's basically a 1 in that place.
-5.8 - 1(-8.4) would be just as correct. (If this helps visually clarify anything.)
So we take that -1 and multiply it by that -8.4. Multiplying 1 against anything leaves it the same, so we just need to change the sign. Two negatives make a positive.
-5.8 + 8.4
Now we add these together.
This gives us our final answer of 2.6
Let the volume of the cylinder be V cubic meters, the diameter be d meters and the height be h meters.
Now we can write the formula for the volume as follows:

Rearranging the formula, the height becomes:
Answer: x = 9/5 or x = 1 4/5
Step-by-step explanation:
2/9 x = 2/5
2/9 * 9/2 * x = 2/5 * 9/2
x = 2/5 * 9/2
x = 9/5 = 1 4/5
