Astrid is looking for a job at a call center. Call center A offers her $15 per hour and call-center B offers her $.25 per minute

mr_godi [17]

Answer: They are the same

Step-by-step explanation: We convert both to $ per hour. Call center A is $15 per hour. Call center B is $.25 per minute. .25 per minute means $1.00 every 4 minutes. There are 15 4 minutes in an hour so they both offer the same wage.

Write an equation in slope-intercept form for the line that passes through (1,9) and (3,5).

kozerog [31]

Answer:

The answer to your question is y = -2x + 11

Step-by-step explanation:

A (1, 9)

B (3, 5)

- Find the slope

$m = \frac{y2 - y1}{x2 - x1}$

$m = \frac{5 - 9}{3 - 1}$

$m = \frac{-4}{2}$

m = - 2

- Find the line equation

y - y1 = m (x - x1)

y - 5 = -2(x - 3)

y - 5 = -2x + 6

y = -2x + 6 + 5

y = -2x + 11

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
