The table that represents a proportional relationship is:

x = -1, -3, -5

y = 1, 3, 5

<h3>Which table represents a proportional relation?</h3>

A proportional relationship is written as:

y = k*x

Where k is the constant of proportionality.

Notice that for equidistant increases in x, we should have equidistant increases on y. Also, proportional relations always have the point (0, 0)

Then the table that represents a proportional relationship is:

x = -1, -3, -5

y = 1, 3, 5

Where the proportional relation is:

y = (-1)*x

When x = -1

y = (-1)*(-1) = 1

When x = -3

y = (-1)*-3 = 3

When x = -5

y = (-1)*(-5) = 5

So the correct option is the second one.

A submarine dives 300 feet every 2 minutes, and 6,750 feet every 45 minutes. Solve for A and

Gelneren [198K]

A: To find the rate in feet per minute, we can use the information given.
Every two minutes, the submarine dives 300 feet. So
$\frac{300feet}{2minutes} = 150 \frac{feet}{minute}$ .
In order to confirm that our rate is correct, we can use the second set of information given.
$\frac{6750feet}{45minutes}$ = $150 \frac{feet}{minute}$ .
Since we know that the rate is 150 feet per minute, we can multiply it by any number of minutes and get the answer of how deep the submarine is. We can use a variable x to represent the number of minutes and y to represent the depth in feet.
$y=150x$
There's our equation.
B: It would be more reasonable to use an equation with the rate feet per minute because it is more accurate since the time interval isn't too big.

Based on your knowledge of taxes, you estimate that your net pay will be 66% of your gross pay. You think you will need $250 per

Sholpan [36]

The gross pay per year is $\fbox{\bf\$19697.6}$ .

Further explanation:

Given:

The net pay is 66% of the gross pay. The net pay per week is $250.

Calculation:

Consider the gross pay as $x$ and net pay as $y$ .

Since the net pay $y$ is 66% of the gross pay $x$ , it can be written as follows:

$\begin{aligned}\frac{{x\times66}}{{100}}&=y\\x&=\frac{{y\times 100}}{{66}}\\x&=1.5151y\\\end{aligned}$

The net pay per week is given as $250.

Substitute 250 for $y$ in above equation.

$\begin{aligned}x&=1.5151\left( {250}\right)\\&= 378.8\,\,{\text{dollar}}\,\,{\text{per}}\,{\text{week}}\\\end{aligned}$

Since, there exist 52 weeks in a year, the gross pay per year is calculated as follows:

$\begin{aligned}x &= 378.8\left({52} \right)\\&= 19697.6\,\,{\text{dollar}}\,\,{\text{per}}\,{\text{year}}\\\end{aligned}$

Thus, the gross pay per year is $19697.6.
