Answer:

2 g/cm³

Step-by-step explanation:

The volume is not given, so find that first:

2 cm x 3 cm x 2 cm = 12 cubic cm = V

Mass is given: m = 24 g

Using the density formula, solve:

d = m/V

d = 24 g/12 cubic cm

d = 2 g/cubic cm

Orlov [11]

Answer:

8696.10

Step-by-step explanation:

If a car depreciates by 7% each year, this means that 7% of its value that year is subtracted from its previous value. In other words, you can multiply its value by (1-0.07)=0.93.

$12500\cdot 0.93^5\approx 8696.10$ . Hope this helps!

If the question is how much Cody will jog to save ratio 4miles:3 miles
The ratio is $\frac{3}{4}$
We can just multiply 1 miles by ratio to see how much Cody will jog, so
$1* \frac{3}{4} =\frac{3}{4}$ miles
The result is $\frac{3}{4}$ miles

Answer:

$60

Step-by-step explanation:

So from the question, we need to find the fixed amount for the tv's. So we have to make an equation, and don't forget to add the extended warranties:

11(x + 25) = 935

x will represent a tv, and the 25 is the extended warranty for a tv, since the questions states 11 tv's with warranties is 935, the equation will look like that. Now lets slove:

11(x + 25) = 935

multiply

11x + 275 = 935

subtract 275 from both sides

11x = 660

divide both sides by 11

x = 60, each tv is $60
