I don't know the real answer, but I think it is C. (I am sorry if I am wrong).
4. 24 because 30-6=24
6. 18 because 8+10=18
8. 97 because 32+65=97
3,000 + 800 + 90 + 7 + 0.003
Answer:
6.87 g/mL
Step-by-step explanation:
The density of an object can be found by dividing the mass by the volume.

We know that the aluminum occupies a volume of 12.7 milliliters and weighs 87.3 grams. Therefore, the mass is 87.3 g and the volume is 12.7 mL.

Substitute the values into the formula.

Divide 87.3 g by 12.7 mL

Round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 7 in the hundredth place.

The density of the aluminum is about 6.87 grams per milliliter.
