When David first got a job, his annual income was $20,000. He worked hard and got more experience. After 8 years, he realized th
at his average increase in pay was about $4,000 every year. Which scatter plot represents this situation?
1 answer:
Answer:
The equation would be:
y= 4,000(x-1)+20,000
y= annual income
x= number of years
With this you can find the points for the scatter plot:
x=1 y= 20,000
x=2 y= 24,000
x=3 y= 28,000
x=4 y= 32,000
x=5 y= 36,000
x=6 y= 40,000
x=7 y= 44,000
x=8 y= 48,000
The scatter plot that represents this situation is attached.

It costs $ 3.4 to fill the hot tub
<h3><u>Solution:</u></h3>Given that, You are putting a rectangular hot tub on your back porch
The rectangular hot tub is of shape cuboid
<em><u>The volume of cuboid is given as:</u></em>
It is 6 feet long, 5 feet wide, and 3 feet deep
Therefore,
length = 6 feet
width = 5 feet
height = 3 feet
<em><u>Thus volume of rectangular hot tub is:</u></em>
Thus volume of rectangular tub is
Convert feet to gallons
We know that,
1 cubic feet = 7.48052 gallon
Therefore,
90 cubic feet = 7.48052 x 90 = 673.247
Thus gallons of water tub can hold is 673.247 gallons
Given that it costs $ 5 per 1000 gallons
1000 gallons = $ 5
Therefore,
1 gallons = $
<em><u>Find for 673.247 gallons</u></em>
673.247 gallons =
Thus it costs $ 3.4 to fill the hot tub
