Density = Mass / volume is the original equation.
If we change it to solve for mass:
Mass = (Density)(volume)
Plug in the numbers:
M = (2.70 g/cm^3)(6.0cm^3) = 16.2 g
Hope that helps! :)
First, we need to figure out 10% of fifteen.
So, we multiple 15 by 10% (or 0.1 in simpler terms).
That gives us 1.5, which is our mark-up price.
So, finally we add the markup price to the original price to obtain the selling price.
1.5 + 15 = 16.5

A rational number is defined as a number that can be written
as a ratio of whole numbers. If it can't then it isn't.
Answer:
$3474.25
Step-by-step explanation:
Use the compound amount formula A = P(1 + r)^t. Here r is the rate as a decimal fraction and is -0.15. t represents the number of y ears. P is the initial value of the car.
Then: A = ($15,000)(1 - 0.15)^9, or
A = ($15,000)(0.85)^9 = $3474.25
