Answer:
Step-by-step explanation:
Density of copper = 9.86 g / cm^3 = 9860 kg / m^3
= 9.86 x 1 / 1000 kg / cm^3 = 9.86 / 1000 Kg / cm^3
= 0.00986 kg / cm^3
= 9.86 x 1 / 1000 kg (1 / 100 m)^3
= 9.86 x 1000000 / 1000 kg / cm^3
Mass "m" = 9860 kg / m^3
thus the mass of copper in solid form is m = 9860 kg / m^3
We divide 100 with 7
100:7=14(2)
so there are left 2 cubes
right answer is b

Answer:
90
Step-by-step explanation:
- change mixed number to improper fraction 22 1/2 = 22*2+1/2 = <u>45/2</u>
- now flip numbers on the second fraction 1/4 = 4/1
- now you can multiply across 45*4 and 18*2 = 180/2
- and simply so its 90
