Answer:
9 inches on the map represents 396 miles.
Step-by-step explanation:
Here let's convert 44 miles to inches.
44 miles is 2787840 inches.
So according to the map, 1 inch = 2787840 inches.
We need to multiply both of these values by 9 to find out how many miles 9 inches represents.
1 inch = 2787840 inches
1 * 9 inches = 2787840 * 9 inches
9 inches = 25090560 inches.
Then convert back to miles.
25090560 inches = 396 miles.
That means, 9 inches on the map represents 396 miles.
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
