Answer:
6:22
Step-by-step explanation:
4:55 + 1:27 = 6:22
The formula is V=Bh
You'd get the base (it's a circle so you'd have to do A=pie*radius square)
Once you find the base, you mutliply it by the height
Negative exponets are like normal ones
ex. 2^-2=-4 another way to do it 2^-2=2^2 with a - so you can do 2^2=4 add the - and it becomes -4.
5.5x+13.5y=40
x+y=5.8
x=5.8-y
5.5(5.8-y)+13.5y=40
31.9-5.5y+13.5y=40
8y=8.1
y=1.0125 or about 1.0 hours
x=4.7875 or about 4.8 hours
