The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?

A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile

Answers

Answer:

A. d = 25; the unit rate is 25 miles per gallon

Step-by-step explanation:

The point (1, d) on the graph represents (x, y), where,

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.

Which equation shows a slope of 2/3 and a y-intercept of (0,-2) ?

Answers

Answer:

Y=2/3x -2

Step-by-step explanation:

Slope 2/3

Y intercept -2

The equation which has a slope of 2/3 and a y-intercept of (0, -2) is; 2x -3y = 6

Slope and y-intercept of straight line equations

From line geometry, it follows that the slope of a given straight line is the rate of change in variable y due to a change in variable x.

Hence, the resulting equation is;

2/3 = (y -(-2))/(x-0)

By cross-multiplication;

3y + 6 = 2x.

Your restaurant bill comes to $46.27. Estimate a 10% tip.

Answers

If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.

What is percentage?

Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.

How to calculate percentage?

We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.

Tip=Bill*10/100

=46.27*10/100

=4627*10/100*100

=46270/10000

=$4.627

Hence if the bill of the restaurant is $46.27 then tip will be $4.627.
