Question

Jolene is creating a model of a pyramid. The model created will need to be scaled up from the blueprint. If segments DE and AB are parallel, which of the following expressions will help Jolene determine the length of segment AC

Answer 1

To determine the length of segment AC in Jolene's scaled-up model of a pyramid, apply the scale factor to the length of the base segment AB.

Step-by-step explanation:

The length of segment AC can be determined using the proportion in the blueprint scale. In the blueprint, segment AB represents the actual length of the pyramid's base, and segment DE represents the corresponding length in the model. Since segments DE and AB are parallel, we can apply the scale factor to find the length of segment AC. If the scale factor is n, then the length of segment AC can be found using the expression n * AB.

Answer 2

The expression that can help you to determine the length of segment AC would be = AC = CB * CD/CE. That is option A.

How to determine the correct expression for the segment?

To determine the correct expression, the following steps should be taken as follows:

The ratio of the corresponding sides;

CD/AC = CE/CB

make AC the subject of formula;

AC = CD×CB/CE.
