Find the ratio AP/PB for 100 points ASAP

shtirl [24]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

To find the ratio of AP/PB, find the distance between A and P, then P and B.

Distance between A(-5, 6) and P(1, 4):

$AP = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$A(-5, 6) = (x_1, y_1)$

$P(1, 4) = (x_2, y_2)$

$AP = \sqrt{(1 -(-5))^2 + (4 - 6)^2}$

$AP = \sqrt{(6)^2 + (-2)^2}$

$AP = \sqrt{36 + 4} = \sqrt{40}$

Distance between P(-1, 2) and B(1, -2):

$PB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$P(1, 4) = (x_1, y_1)$

$B(13, 0) = (x_2, y_2)$

$PB = \sqrt{(13 - 1)^2 + (0 - 4)^2}$

$PB = \sqrt{(12)^2 + (-4)^2}$

$PB = \sqrt{144 + 16} = \sqrt{160}$

$\frac{AP}{PB} = \frac{\sqrt{40}}{\sqrt{160}}$

$= \frac{\sqrt{40}}{2\sqrt{40}}$

$= \frac{1}{2}$

Sarah’s mom took 3 hours to clean, but when Sarah helped, it took them 2 hours to clean. How many hours will it take Sarah to cl

Aleonysh [2.5K]

Answer:

<em>It takes them 1.875 hours.</em>

<em></em>

<em>Step-by-step explanation:</em>

<em></em>

<em>Here, the job is cleaning the house.</em>

<em></em>

<em>Mom does 1 job in 3 hours.</em>

<em></em>

<em>In 1 hour, mom does 1/3 of the job.</em>

<em></em>

<em>Dad does 1 job in 5 hours.</em>

<em></em>

<em>In 1 hour, dad does 1/5 of the job.</em>

<em></em>

<em>Mom and dad working together do the job in x hours.</em>

<em></em>

<em>In 1 hour, mom and dad together do 1/x of the job.</em>

<em></em>

<em>1/3 + 1/5 = 1/x</em>

<em></em>

<em>5/15 + 3/15 = 1/x</em>

<em></em>

<em>8/15 = 1/x</em>

<em></em>

<em>8x = 15</em>

<em></em>

<em>x = 15/8 = 1.875</em>

<em></em>

<em>Answer: It takes them 1.875 hours.</em>
