What do you need help on? Just post the question.
Answer:
66 minutes, or 1 hour and 6 minutes.
Step-by-step explanation:
let us first do the rectangular aquarium:
8 x 10 = 80
80 x 14 = 1120
now the second box
23 x 25 = 575
575 x 33 = 18975
we can divide the boxes volume:
18975/575 = 33
so all we have to do is times 33 by 2 which equals:
66 minutes, or 1 hour and 6 minutes.
Answer:
4. Divide both sides by l.
Step-by-step explanation:
You are trying to find out the answer for "w" so you need to get it alone on one side. Because "l" and "w" are multiplied together, you will have to divide "l" from both sides in order to get "w" by itself.
I really don't know how toowrk it out on paper, I'm afraid. I just looked at it, and somehow knew that the answers are 7 and 9.
