This is a chemistry problem btw. But, either way, the formula for density is mass per unit of volume. To solve for volume, bring the D over to get M/D = V
(327g)/(1.05g/ml) is the equation. Grams cancel and you’re stuck with 311.428571mL. That isn’t your answer tho, because that isn’t the right amount of sig figs. We have two figs at the least so the right answer would be 311.42 or 311.43mL. We want it in scientific notation, so move the decimal place between 3 and 1. That’s two spots to the left, so the power would be 2. C is your right answer
My chem professor told me to round to even instead of rounding up all the time. Either way, the hundreds place is always a percent error of plus or minus 0.01
Answer:
D if car's length is 180 and not 108
Step-by-step explanation:
Truck is 75% longer than the car implies that the length of the truck is 175% (100+75 = 175) of the length of the car.
175/100 × 108
= 189 inches
None of the above
If we take the car's length to be 180 inches, then
175/100 × 180 = 315 inches
Is there more to the questions or is this all of it?
