Answer:
9g/mL
Step-by-step explanation:
The density of something is mass/volume and the density of something never changes, no matter how much or how little there is of it.
We know that the mass of Cu (copper) is 45g and its volume is 5.0mL.
density = 45g/5.0mL
Plug that into a calculator and you'll get your answer.
Answer:
true
Step-by-step explanation:
Answer:
First should get $220, other two should get $140 each.
Step-by-step explanation:
The ratio of hours the friends worked is 11:7:7. Say that they are paid 11x, 7x, and 7x respectively, therefore:
11x + 7x + 7x = 500
25x = 500
x = 20 so the first friend should get 11 * 20 = $220 and the other two should get 20 * 7 = $140 each.
