Zielflug [23.3K]

1 board that is 10 feet long and make that into 6 table legs. Take the amount we have over the amount we want, so 10 over 6 which is 1.6666667 feet which is the longest each leg can be for a 10-foot board.

Answer:

<em>16.5 gallons per minute.</em>

Step-by-step explanation:

The given table is:

$\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50 \\ 1.5 & 24.75 \\ 2 & 33 \\\end{tabular}\end{center}$

We are given this linear function in the form of table.

Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.

We can use slope intercept form to find the equation.

$y=mx+c$

Slope of a function:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50$

$m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5$

This slope is the constant of proportionality.

i.e. the rate at which the number of gallons are changing per minute.

So, the answer is <em>16.5 gallons per minute.</em>

Answer:

BC = 60

Step-by-step explanation:

3X + X = 80 <---- X = BC

3X + X = 4X

4X = 80 <---- DIVIDE BOTH SIDES BY 4

4X ÷ 4 = X

80 ÷ 4 = 20

20 × 3 = 60
