Answer:
Step-by-step explanation:
The systems of equations are
Let us assume the rate of the current be c
Now actual speed against the current is (15 - c)
And, the actual speed with the current is (15 + c)
Here we applied the time formula i.e. distance by speed
Also the upstream time - downstream time = 4
Now the equations are
Answer:
18
Step-by-step explanation:
Just divide both sides by - 64
1st part: 3x9x3
2nd part: 3x6x9
3rd part: add the product of those two steps
you have to break it down into two rectangular prisms and find the volume of each and then add
Answer:
A
Step-by-step explanation:
ok so pretend the 2.00 was just 2 so whats 8 divided by 2? 4 right so if we test that witht he other problems its the same so its A
Hope this helps!!!! :D
Step-by-step explanation:
given,radius =5 m
height =8 m
now, v=pi×r^2×h
=(3.14×5^2×8)m^3
=628m^3
therefore the volume is 628m^3 is the answer
