Bas_tet [7]
I think the question is asking for the cost (C) when we already know that the sell price (S) is $24

C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents

A beach ball has a mass of 5 g and a volume of 20 cm3. What is the object's density? A. 4 g/cm3 B. 100 g/cm3 C. 0.25 D. g/cm3 4
Triss [41]
<h2>Hello!</h2>

The answer is:

C.  0.25\frac{g}{cm^{3} }

<h2>Why?</h2>

The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:

Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}

So, the correct options is C.  0.25\frac{g}{cm^{3} }

Have a nice day!

Use a net to find the lateral area and the total surface area of the cereal box.
ziro4ka [17]
To find the lateral area you will find the area of all 4 faces that are perpendicular to the base.

You will multiply the side by the length (front/back) and the side by the width (sides).

12 x 8 = 96
12 x 2 = 24
120 square inches x 2 = 240 square inches

The lateral area is 240 square inches.

The area of the base is 8 x 2 = 16 square inches.

16 x 2 = 32 square inches

240 square inches + 32 square inches = 272 square inches is the surface area.
