A and B can do a work in 3 days but A working alone takes 4 days. In what time will B do it if he works alone?

zalisa [80]

Answer:

Let B have x days work:

A + B = 3 days

1/4 + 1/x = 1/3

1/3 - 1/4 = 1/x

1/12 = 1/x

x = 1 / (1/12)

x = 12

B takes 12 days

I do not know if this is right

What is the slope of the line? A) -1/3 B) 1/3 C) -3 D) 3

Vladimir79 [104]

Answer:

Hey there!

A simple way to think about slope is rise over run. Between any two points on this line, the rise is 3, and the run is -1.

3/-1=-3, so the slope is -3.

Let me know if this helps :)

Given the figure below and that segment VW is the midsegment ΔRST, what is m∠WVR?

jolli1 [7]

Answer:

∠WVR = 156

Step-by-step explanation:

Angles in triangle add up to 180 - SEE ATTACHMENT - LEFT TRIANGLE

∴ ∠SRT + RST + RTS = 180

∴ ∠SRT + 109 + 47 = 180

∠SRT = 24

Alternate Angle Theorem - SEE ATTACHMENT - RIGHT TRIANGLE

∠SRT = 180 - ∠WVR

24 = 180 - ∠WVR

24 - 180 = - ∠WVR

-156 = - ∠WVR

∠WVR = 156
