The total cost for a bucket of popcorn and 4 movie tickets is $56. The total cost for the same size bucket of popcorn and 6 movie tickets is $80. Which equation represents the relationship between y, the total cost of the popcorn and movie tickets, and x, the number of movie tickets that are purchased

Answers

y+4x=56
y+6x=80

I think these are the two equations that should be used to solve for 'y' and 'x'!!

What is an equation of the line that passes through (0,8) and (4,0)?

Answers

Answer: y=-2x+8

Step-by-step explanation:

To find the slope of the line, you would use $(y_(2)-y_(1) )/(x_(2) -x_(1) )$ . With the 2 points we are given , we can plug it into this equation to find the slope.

$(0-8)/(4-0) =(-8)/(4) =-2$

Now we know the slope is -2. To find the y-intercept, we know that the x value is 0. We are given that one of the points is (0,8). That means 8 is our y-intercept.

The final equation we get is y=-2x+8.

Answer:

y= -2×+8

Step-by-step explanation:

find m(slope)

y2-y1 over x2-x1

substitute using (0,8) and (4,0)

m=-2

y=mx+b

substitute x and y to find b using either (0,8) or (4,0)

0=-2(4) + b

0= -8 +b

0+8= -8+8 +b

8=b

y=-2x+8

According to the EPA, about 40 million U.S. tons of hazardous waste is produced each year. If individual household waste makes up 1.6 million tons of this waste, what percent of the total hazardous amount produced is household waste? A. 0.04% B. 0.03% C. 0.25% D. 2.5% E. 4%

Answers

Answer:

C.0.25%

Step-by-step explanation:

40/1.6=25

Then convert to percentage value by moving the decimal 2 places to the left.

25 turns into 0.25.

What is the median for the set of data?
6,7,10,12,12,13

Answers

The median for this set of data is 11.

Work is provided in the image attached.

the median is 11 because to find the median you rank the numbers from least the greatest, but in this case there are two middle numbers 10 & 12, so to get the median you add 10+12=22 which equals 22 the divide it by 2 which now makes it 11. and that's you answer
