Pls help me solve please show how you got the answer pls help

3/2 cm^2 or 1.5 cm^2

Step-by-step explanation:

Remark

This is another one of those very poorly design questions where a lot is taken for granted. There is nothing to show the the black square has an area of 1/4 square cm. or the white square is 1/2 cm^2. You are left to speculate, and you should never have to guess a dimension from a diagram.

That said here are the assumptions

White square area = L * W

L = 1 (which comes from 1/2 of 2)

W = 1/2

Area = 1 * 1/2 = 1/2

There are two them them so their area = 1

The black squares are 1/2 * 1/2 = 1/4 square cm. There are two of them so their total area = 1/2 square cm.

Total of the white and black squares = 1 + 1/2 = 1 1/2 or 3/2 square cm.

c is the answer

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
