Step-by-step explanation:
14/y=112/72
simplify 112/72 into 14/9
14/y=14/9
y=9
Answer: 
Step-by-step explanation:
In the given picture , the line is parallel to the y- axis and passing through (-2,2) and (-2 , -3).
The equation of line parallel to y-axis (has slope undefined) is given by
x= a , where a is the point on x-axis through which the line is passing .
For the given graph , the line is passing through x = -2.
Therefore , the equation of the given line =
Hence, the correct answer =
For number 4 subtract 32.56 - 29.40 and the answer should be 3.16.
The number of minutes it will take 5 machines to make 15 widgets is 90 minutes
Given that :
The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.
Using the variation protocol defined :
Let :
n = number of widgets made
n = number of widgets made m = number of machines used
n = number of widgets made m = number of machines used t = time taken
Hence, from joint variation :
t α n α 1/m
t = kn/m
Where k = constant of proportionality :
Solving for k
When t = 10, n = 5, m = 15
10 = (k × 5) / 15
15 × 10 = 5k
150 = 5k
k = 150 / 5
k = 30
Equation becomes :
t = 30n/m
Solve for t ;
When m = 5 ; n = 15
t = (30 × 15) / 5
5t = 450
t = 450 / 5
t = 90
Hence, it will take 90 minutes.
