Answer:
7 units
Step-by-step explanation:
Given that :
house is at (−4, 10). Her school is at (−4, 3)
House location = (-4, 10)
School location = (-4, 3)
Distance from house to school (d) :
Distance between two points :
x = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
x1 = - 4 ; y1 = 10 ; x2 = - 4 ; y2 = 3
d = sqrt[(-4 - (-4))^2 + (3 - 10)^2]
d = sqrt[(-4 + 4)^2 + (-7)^2]
d = sqrt(0 + (-7)^2)
d = sqrt(49)
d = 7 units
Choice b would be correct since the slope of the line is negative !
Answer: Number of hours they all will take is
Step-by-step explanation:
Since we have given that
Number of hours Walter and Bill takes to do the job = 4 hours
Number of hours Tom alone takes to do the job = 3 hours
We need to find the number of hours takes them together to decorate the room.
Work done by Walter and Bill =
Work done by Tome =
total work done by three is given by
Hence, Number of hours they all will take is
