A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 55 ​seconds, th
True [87]

Answer:

y=3x+4

Step-by-step explanation:

Let y be the amount of water in the bottle x seconds after the faucet was turned on.

We have been given that the gauge on the bottle indicates that it contains 19 ounces of water after it has been filling for 5 seconds. After it has been filling for 11 ​seconds, the gauge indicates the bottle contains 37 ounces of water.

We have two points on the line (5,19) and (11,37).

Let us find slope of the line passing through these points.

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{37-19}{11-5}

m=\frac{18}{6}

m=3

We will write our required equation in slope-intercept form y=mx+b, where, m represents slope and b represents the y-intercept.

Let us find y-intercept by substituting m=3 and coordinates of point (5,19) in slope intercept form.

19=3\cdot 5+b

19=15+b

19-15=15-15+b

4=b

Therefore, our required equation would be y=3x+4.

Howard bought 3/5 pounds of granola. He divided the granola evenly among 4 friends. How much granola did each friend get?
Alex17521 [72]

Answer:

(0.75) is the amount that each freind has.

Step-by-step explanation:

We see that Howard did NOT purchase not one pound of granola. Its only 60% of a pound. Therefore we'd do 60% divided by 4 and therefore get .75%. Each freind ate .75% of that granola.
