What is a reasonable domain for this situation?

Mathematics

Answer:

B

Step-by-step explanation:

The y-axis shows the number of gallons of water left (with respect to time).

The x-axis shows the time.

Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.

Looking at the choices, that is B, 0 ≤ x ≤ 12

Jaime has 5 over 11 spaceof a project completed while Tim has finished 7 over 13 spaceof the same project.
faust18 [17]

Answer:

a. Tim has completed a greater amount of work.

b. Together they have completed \frac{142}{143} part of two projects.

Step-by-step explanation:

Let us assume that the project on which Jaime and Tim are working has x amount of space.

Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.

Therefore, Jaime has completed \frac{5x}{11} amount of space and Tim has finished \frac{7x}{13} amount of space.

a. Now, (7x) \times 11 > (5x) \times 13

⇒ \frac{7x}{13} > \frac{5x}{11}

Therefore, Tim has completed the greater amount of work. (Answer)

b. Together they have completed (\frac{7x}{13} + \frac{5x}{11}) = \frac{(7 \times 11 + 5 \times 13)}{13 \times 11} x = \frac{142}{143}x amount of space out of 2x amount of space. (Answer)

Find the value of the following expression:<br> (28.5-5. 199-2.<br> )<br> 228
USPshnik [31]
<h2>Answer with step-by-step:</h2>

(28.-5.199-2.)228

<em>Subtract 5.199 out of 28 to get 22.801</em>

(28.-5.199-2.) * 228

<em>Subtract 2 of 22.801 to get 20.801</em>

20.80 1 * 228

<em>Multiply 20.801 and 228 to get 4742.628 </em>

4742.628<em> </em>

<h2>The answer if you need to factor it:</h2>

3*11*19*31*61/2*5^3 = 4742 157/250 = 4742.628
