Please Help! The graph relates the height of the water in a tank y (in inches) to the volume of the water x (in gallons).

A. Is the relationship proportional?

B. Write an equation of the line and interpret the slope.

C. What is the height of the water in the tank when the volume is 250 gallons?

The graph is attached.

Answers

Answer:

I Believe it is B

Step-by-step explanation:

x=100 and y=6

A. The relationship is directly proportional.

B. The required equation is x = 20y

C. The height of the water is 12.5 inches.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

From the graph, we obtain two pair of points (1, 20) and (2, 40).

∴ Slope(m) = (2 - 1)/(40 - 20) = 1/20.

Now, 40 = 20(2) + b.

b = 0.

So, y = 20x is the required equation.

A. The relationship is directly proportional.

B. The required equation is x = 20y.

C. The height o the water when the volume is 250 gallons is 250 = 20y

y = 12.5 inches.

Jolianne worked half as many hours as Andrew. Jolianne makes $10 per hour and has saved $27. Andrew makes $8 per hour and has no money saved. After getting paid, they have the same amount of money.
Andrew claims that only his table and equation are correct, but Jolianne claims that both tables and equations are valid. Which statement regarding their claims is true?

A.) Andrew is correct because t cannot be used to represent the number of hours Jolianne worked.

B.) Andrew is correct because Jolianne worked half as many hours as he did and he did not work twice as many hours as she did.

C.) Jolianne is correct because if one lets t = hours Andrew worked, then his equation is valid. If one lets t = hours Jolianne worked, then Andrew worked twice as many so her equation is valid, too.

D.) Jolianne is correct because when solving t in her equation, t = hours Jolianne worked, and when solving for t in Andrew’s equation, t = hours Jolianne worked so they are equal.

What is the area of this figure?

Enter your answer in the box.

Answers

The answer is 28 I think

Answer:

400 sq. in.

Step-by-step explanation:

the parallelogram in the figure has an area of 320 sq. in.

and the right triangle at the top right has an area of 80 sq. in.

adding both areas would equal to 400 sq. in.

( if you're wondering,what about the right triangle at the bottom left?Well that triangle actually gives us the height of the parallelogram which is 16.therefore the triangle's area is already found in the area of the parallelogram.As you should know the area to a parallelogram is A=bh ,and the base is 20 so multiplying 16 x 20 that equals 320.Therefore the triangle's area is already found in the area of the parallelogram.)
