How many feet long is the shadow of a 15-foot flagpole if a 5-foot woman standing at the base of the flagpole has a shadow that

Vikentia [17]

The height of flagpole is 12.5 feet.

Step-by-step explanation:

Given,

Height of woman = 5 foot

Shadow of woman = 6 feet

Ratio of height to shadow = 5:6

Shadow of flagpole = 15 foot

Height of flagpole = x

Ratio of height to shadow = x:15

Using proportion;

Ratio of height to shadow :: Ratio of height to shadow

$5:6::x:15\\$

Product of mean = Product of extreme

$6*x=15*5\\6x=75$

Dividing both sides by 6

$\frac{6x}{6}=\frac{75}{6}\\x=12.5$

The height of flagpole is 12.5 feet.

What is the k?<br> k + 8/3 = -2

Leto [7]

Step-by-step explanation:

$k + \frac{8}{3} = - 2$

$\frac{3k + 8}{3} = - 2$

Cross Multiplying

$3k + 8 = - 6$

$3k = - 6 - 8$

$3k = 14$

Therefore

$k = \frac{14}{3}$
