Help! Ratios and Porportions

1 answer:

SOVA2 [1]2 years ago

We learned that ratios are value comparisons, and proportions are equal ratios. Ratios can be written with colons or as fractions. So, to compare the number of girls to boys in a litter of puppies, we can write 2:4 or 2/4 to say that there are two girls to four boys.

Square ABCD is located on a coordinate plane. The coordinates for three of the vertices are listed below.

Roman55 [17]

ANSWER

B' has coordinates (16,14).

EXPLANATION

The given coordinates of square ABCD are :

A (2,7) , C (8,1),D (2,1)

In order to form a square, the coordinates of B should be: (8,7)

The mapping for dilation with a scale factor 2, about the origin is

$(x,y)\to (2x,2y)$

This implies that:

$B(8,7)\to B'(2 \times 8,2 \times 7)$

When we simplify we get:

$B(8,7)\to B'(16,14)$

Hence B' has coordinates (16,14).
