Mathematics

Bond [772]2 years ago
6 0

Answer:

2 days

Step-by-step explanation:

Understanding :

  • Number of men is inversely proportional to the number of days taken to complete a job
  • 6 men take 5 days to complete 1
  • Now the number of men is 15

Solving :

  • Rate of change of men ∝ 1/Rate of change of days
  • 15/6 ∝ 1/(d/5)
  • 2.5 = 5/d
  • d = 2 days

What is the slope of the line?
Katyanochek1 [597]

Answer:

1

Step-by-step explanation:

slope (k) is the rise over run of the line

a way of finding the slope if you have two dots of the line is:

k \:  =  \frac{y2 - y2}{x2 - x2}

here the dots that belong to the line that you can most easily see are:

A(-6,0)

B(0,6)

by inserting the values into the euquation you get:

\frac{6 - 0}{0 - ( - 6)}  =  \frac{6}{6}  = 1

good luck with your maths solving
