Answer:

For every table served, Bradley's pay increases by an average of 4

Step-by-step explanation:

The line of best fit for the graph is y = 4x + 25 ; where, y = total pay and x = tables served

Using the slope intercept relation : y = mx + c ; where, m = slope

y = 4x + 25 ; the slope of the graph is 4

This means the rate of change of x with respect to y is 4 ;

This means for every unit change in x ; y increases by 4

For every table served, total pay increases by 4

Deborah has two paintings in her portfolio and paints three more each week.Kai has twelve paintings in her portfolio and paints
elena-14-01-66 [18.8K]
Well, we can set up these equations like this-
Deborah- 2+3w
Kai- 12+2w
w=number of weeks that pass
Now, we set them equal to each other:
2+3w=12+2w

Solve for w
2-12=2w-3w
-10 = -1w
w = 10
10 weeks. Hope this helped!

A structural steel fabricator cuts 25 pieces each 16.2 centimeters long from a 6.35-meter length
Daniel [21]

Answer: 2.2 meters

Step-by-step explanation:

The data is:

The initial piece is 6.35 meters long.

We cut 25 pieces of 16.2cm each, so in pieces only we have:

25*16.2cm = 405cm

1m = 100cm

Then: 405cm = (405/100) m = 4.05m

And each time that we cut a piece, we have 4mm of waste.

Then we have 25 times the 4mm of waste, this means that the total waste is:

4mm*25 = 100mm

and 1000mm = 1m

100mm = (100/1000) m = 0.1m

So the total amount that was cut is:

4.05m + 0.1m = 4.15m

The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters
