Find the coordinates of the midpoint of the segment whose endpoints are H(2, 1) and K(10, 7).

marishachu [46]

Midpoint = $( \frac{X1+X2}{2} , \frac{Y1+Y2}{2} )$

Mdpt = $( \frac{2+10}{2} , \frac{1+7}{2} )$
= $( \frac{12}{2} , \frac{8}{2} )$

= (6, 4)

That is your midpoint.

Mia and Holly can clean their room in 20 min, working together. Mia, working alone, can do the job in 30 min. How many minutes w

Sindrei [870]

Answer:

Option B. is correct

Step-by-step explanation:

Let $x$ denotes time taken by Mia alone to clean the room and $y$ denotes time taken by Holly alone to clean the room.

As Mia and Holly can clean their room in 20 min, working together,

$\frac{1}{x}+\frac{1}{y} =\frac{1}{20}\,\,\,...(i)$

Also,

Mia, working alone, can do the job in 30 min.

So,

$\frac{1}{x}=\frac{1}{30}\,\,\,\,\,...(ii)$

Put (ii) in (i)

$\frac{1}{30}+\frac{1}{y}=\frac{1}{20}\\\frac{1}{y}=\frac{1}{20}-\frac{1}{30}\\\frac{1}{y}=\frac{3-2}{60} \\\frac{1}{y}=\frac{1}{60}$

Therefore,

Holly can clean the room alone in 60 minutes.

Option B. is correct
