Answer:

Hey buddy, here is your answer. Hope it helps you.

Step-by-step explanation:

80/100*72=57.6

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 $y=3x+4$ .

Find 15.75 ÷ 0.25 using a Giant One.

MA_775_DIABLO [31]

15.75 divided by 0.25

In every 1 whole number, there are 4 of 0.25

Now we have 15 as whole number so simply multiply 15 x 4

15 * 4 = 60, there are 60 pieces of .025s in 15.

0.75 has 3 0.25s

Now, let’s add 60 + 3 = 63, the answer is 63.

There are 63 pieces of 0.25 in 15.75.

15.75 / 0.25
