Answer: y = (1/8)x + 3.625

Step-by-step explanation:

slope: y = mx + b

change from 3 to 4 is 1, this is our rise

change from -5 to 3 is 8, this is our run

1/8 = m

this is a really bad explanation but I know that

1/8 is equal to 0.125.

since there are 5 spaces from (-5,3) to the y axis, and that the slope is 1/8, i can multiply 1/8 x 5 to get 5/8.

5/8 =.625

since the x intercept is in between 3 and 4, it is 3.625.

3.625 = b

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%. By what percent must t
Sergeu [11.5K]

Answer: 28 %

Step-by-step explanation:

Let, Initially,

V be the volume of construction work

r be the productivity of labor  

n be the number of days

x be the number workers.

Thus,  V  = r × n × x   ------------(1)      

Now, According to the question,

The volume of construction work was increased by 60% but the productivity of labor increased by only 25%.

Therefore,

Final volume of the work = 160% of V = 1.6 V

Final productivity = 125% of r = 1.25 r

Also, the time is same in both conditions,

Final time taken = n

Let y be the number of people after changes.

Thus, 1.6 V = 1.25 r × n × y -----(2)

Dividing equation (1) by equation (2)

We get, y = 1.60 x/1.25

Thus, the changes in the number of workers

= \frac{(\frac{1.60x}{1.25}-x) }{x}\times 100

= 0.28 × 100

= 28 %
