First man mows the lawn in 6 hours so he mows 1/6 of the lawn per hour

Second man mows at 1/4 lawn per hour

Third man mows at 1/3 lawn per hour

The total of the three: 1/6 + 1/4 + 1/3 = 2/12 + 3/12 + 4/12 = 9/12 = 3/4 of a lawn per hour.

1 lawn / 3/4 lawn per hour =  1 and 1/3 hours all together.

Answer: 1 and 1/3 hours

the slope of the line that passes through the points (-2,y) and (-5,7) is -2/3. what is the value of y?
Iteru [2.4K]

Answer:

5

Step-by-step explanation:

slope = rise/run = (7-y)/(-5-(-2)) = -2/3

3(7 -y) = -2(-3) . . . . . multiply by 3(-3)

7 -y = 2 . . . . . . . . . . . divide by 3

7 -2 = y = 5 . . . . . . . . add y-2

The value of y is 5.

eimsori [14]

Answer:

x=60

Step-by-step explanation:

20 points! I will mark brainliest
IceJOKER [234]

Answer:

the shortest distance is the distance from a point to a line that make 90° .

so AC is the shortest distance.

<h3>step by step explanation</h3>
  • then we have the find the distance between point A and C.
  • to find that we use the distance formula .

d^2=(-3-1)^2 + (-3--1)^2

=(-4)^2 + (-2)^2

=16 + 4

=20

d=√20

this is the distance between point A and point C.

Describe the slope of the line of best fit
Aliun [14]

Answer:

The graph represent a scatter plot between variable A on the horizpntal line and the variable B on the vertical line.

A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.

As shown by graphinf a line through the maximum number of points, balancing about an equal number of points above and below the line, we can deduce that:

<u>The line of best fit drops from left to right, so the variables have a negative correlation. </u>
