The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel. A graph titled Water Supply with number of days on the x-axis and gallons of water left on the y-axis. A line goes through points (6, 33) and (15, 15). What does the y-intercept represent?

Answers

Answer:

its c i guess i thought it was B because it says the amount of water that remains in the water barrel remains means what is left and initially means at first so i guess its C

Step-by-step explanation:

please rate and give me a thanks if you wanna get more answers

Here, we are required to determine what the y-intercept represents.

The equation of a line is given by;

y = mx + c.

where m = slope

and c = y-intercept.

Since the y-axis represents the Gallons of water left in the tank.

The y-intercept represents the point which corresponds to when x = 0.

In this case, the y-intercept represents the amount of water that is initially in the water barrel. i.e 45gallons of water.

Point C ∈ AB and AB=18 cm. The distance from C to A is 3 cm. shorter than the distance from C to B. Find AC and CB.

Answers

Answer:

AC=7.5 cm

CB=10.5cm

Step-by-step explanation:

Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm

Answers

The answer is 324,000 cm3.

Smaller rectangle:

L x W x H
120 x 30 x 30 = 108000


Taller rectangle:

L x W x H
120 x 30 x 60 = 216000

216000 + 108000 = 324, 000 cm3

Answer:

Step-by-step explanation:

upper block:

length (l) = 120 cm

Width (w) = 30 cm

Height (h) = 60 cm

Volume of upper block = l * w * h

                                      = 120 * 30 *60

                                     = 216,000 cm³

Lower Block

l = 120 cm

w = 30 cm

h = 30 cm

Volume of lower block = 120 * 30 * 30

                                      = 108,000 cm³

Volume of steps = 216,000 + 108,000 = 324,000 cm³
