Whats the density of an object with the length of 5.0 cm a height of 3.0 and width of 15.0 cm and a mass of 24 grams
Sphinxa [80]

Answer:

The density of the object is 0.1067 grams per cubic centimeter. (Rounded off to 4th decimal)

Step-by-step explanation:

Density = [Mass/Volume]

Here we have been given the dimensions of the object.

Volume = Height * Width * Length

Volume = 3.0cm*15.0cm*5.0cm

             =225cm^{3}

Now we can substitute the Mass and the Volume to the density equation.

Density = [Mass/Volume]

             =\frac{24grams}{225cm^{3} }

             =0.1067 grams per cubic centimeter. (Rounded off to 4th decimal)

Write an equation for the proportional relationship. Can you compare these two tables?
Viktor [21]

Answer:

Y=1.88x

Step-by-step explanation:

x1=2 x2=3, y1=3.76 y2=5.64

(2, 3.76) (3, 5.64)

m(slope) =5.64-3.76/3-2

m=1.88

y-3.76=1.88(x-2)

y-3.76=1.88x-3.76

Y=1.88x

A power bill can be defined as a utility bill issued by a power utility company (provider) to illustrate the amount of energy (electricity) consumed by a customer.

Power bills usually show the following informations;

2. The Kilowatt hours of electricity used: this represents the amount of electricity that was used by the consumer in the previous month.
