cm length of cube, then there will be (4 × 2) = 8 cubes that can occupy the base.
You would times 5.3x96
This would give you 508.8
You would then divide this by 60, since there is 60 seconds in a minute.
So, 508.8/60= 8.48
She would need 8.48 minutes to sign all 96 invitations
I think she made a mistake at step 4 because I know in order to find the mean absolute deviation of a number you must divide as the last step, not subtract and the rest of her work looks correct.
Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
