Answer:

8. yes

9. no

10. yes

Step-by-step explanation:

8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).

9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.

10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.

The population of Cincinnati is 301,305 people. If 28.7% of people in Cincinnati live poverty, how many people live in poverty

IRINA_888 [86]

Answer:

86,475<em> </em>people live in poverty.

Step-by-step explanation:

We are given that the Total Cincinnati population is $X_{TOT}=301,305$ people.

We want to find the $28.7$ % of the Total population that lives in poverty. To do so we can use:

$X_{POV}=\frac{28.7}{100}X_{TOT}$

where $X_{POV}$ is the amount of people that live in poperty. Plugging in values and solving we have:

$X_{POV}=\frac{28.7}{100}301,305 \\X_{POV}=0.287*301,305\\X_{POV}=86,474.535$

However since here we are referring to number of people (i.e. population) we can not accept any irrational values so we need to round up our value so that

$X_{POV}=86,475$ people live in poverty in Cincinnati.
