Three boys cut out hundredths decimal models. Derrick does not shade any of his models. Ari shades half of one model. Wesley shades two models and one tenth of another model. What decimal represents the amount each boy shades?

The fractional amount of the model shaded by each of the boys are :

The size of each model cut out = 1/100 = 0.01

DERRICK :

ARI :

WESLEY

Therefore, the amount shaded by each of the boys represented as a decimal are :

Derrick's value = 0

Ari's value = 0.5

Wesley's value = 2.1

Explanation:

Derrick doesn't shade anything, so his value is 0.

Ari shades half of one model, so 1/2 = 0.5 is his value

Wesley shades 2 full models, plus 1/10 = 0.1 of another one, leading to 2+0.1 = 2.1 as his value.

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
