Ab is 10. 8 units long if ABC is dilated by a scale factor of k equals 1.3 what is the length of a'b'

Marizza181 [45]

ANSWER

The length of

$A'B'=14.04 \: units$

EXPLANATION

The object length given to us is,

$|AB|=10.8 \: units$

The scale factor of the dilation is,

$k = 1.3$

The image length can be calculated using the formula

$|A'B'| = k \times |AB|$

We substitute the given values into the formula to get,

$|A'B'| = 1.3\times 10.8$

We multiply out to obtain,

$|A'B'| = 14.04 \: units$

At a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men, how many women are there?

Fed [463]

Let 6x represent the men

5x represents the women

The ratio of men to women is 6 to 5 or 6/5

6x / 5x = 1500/ W where W is the number of women

6/5 = 1500/W

W = 1250 women
