Answer:This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).

Step-by-step explanation: If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).

Basically what this assignment sais is to write a function, input the data and write input and output as an ordered pair.

f(x)=3.75x

Where f(x) equals y and 3.75 times x is cost of number of gallons x.

So we have:

f(x)=12\Longrightarrow 12=3.75x \\ 12=3.75x\Longrightarrow x=\dfrac{12}{3.75}=3.2

So the ordered pair is in a form of:

(x, f(x))\Longleftrightarrow(x,y)

We have x is 3.2 and y is 12. So the ordered pair is:

\boxed{(3.2, 12)}

Hope this helps.

The table shows the number of cups of water required when cooking different amounts of rice.
Harman [31]

<u>Answer-</u>

<em>The amount of water is the dependent value.</em>

<u>Solution-</u>

Plotting the graph from the given data points, it comes out to be a straight line with positive slope. So, both the variables i.e amount of rice and amount of water are in a linear relationship. They are directly proportional to each other.

As the amount of rice increases, the water needed to cook the rice also increases. Plotting a graph taking amount of rice in abscissa and amount of water in ordinate, a straight line was obtained.

Here, amount of rice is the independent variable and amount of water is dependent variable as it depends on the amount of rice.

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at
stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

E = PIt

  • E is the amount of interest earned.
  • P is the principal(the amount of money invested).
  • I is the interest rate(yearly, as a decimal).
  • t is the time, in years.

In this problem:

  • Borrowed $2,700, thus P = 2700
  • Interest rate of 3.5%, thus I = 0.035
  • From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is t = \frac{423}{365} = 1.2685

Thus, the interest paid was of:

E = PIt = 2700(0.035)(1.2685) = 119.87

$119.87.
