Width = 5x
length = 7x

Perimeter = 10x + 14x = 24x = 96cm
x = 96/24 = 4cm

width = 5x = 20cm
length = 7x = 28cm

Area = (20cm x 28cm) = 560 cm²

Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hour
gtnhenbr [62]

Solution: Emanuel earns $13 per hour. Also he earns a commission of 5% on all cars he sells.

Number of hours Emanuel worked last month = 40 hours

He sold cars worth $120,000.

Therefore, the total earning of Emanuel is:

13 \times 40 + 5\% of 120,000

520 + \frac{5}{100} \times 120,000

520+6000

6520

Hence, last month Emanuel made $6520, including his hourly pay and commissions.

A gold earring has a mass of 4.5 grams and a density of 18 grams per cubic centimeter. Calculate its volume
White raven [17]
Density = mass/volume
Plug in your Provided Values
v=volume
18g/cm^3 = 4.5g/v. Multiple both sides by v
v(18g/cm^3) = 4.5g Divide both sides by 18g/cm^3.

v = 4.5g/(18g/cm^3) Your grams cancel out leaving 4.5/18 cm^3 as your volume which is also. .25 cm^3.
Hope this helps!
