Answer:

x = 1

Step-by-step explanation:

When you subtract the smallest number from the biggest number, the answer is called the range. Here the largest number is 21. The smallest is 3. Then the range should be 18. But since it's 20. This mean that x is 1. Because 21 - 1 will equal 20, making 20 the range. So the correct answer is 1.

levacccp [35]

Hello,

As said T is the point of intersection of f and g, this means that there are only one point and that k=+1.

So dom f= $R ^{+}_0$ (x>0)

Determine the unit rate of the following.<br> 240 hours of homework in 8 weeks.

astra-53 [7]

Answer: $30\ \frac{hours}{week}$

Step-by-step explanation:

In order to solve this exercise it is important to remember that a "Rate" is defined as a ratio that compares two different but related quantities.

Then, "Unit rate" tell us how many units of the first quantity corresponds to one unit of the second quantity. Therefore, the second quantity is equal to 1.

According to the information given in the exercise, you know that the number of hours of homework in 8 weeks is 240 hours.

Then, in order to determine the Unit rate (the number of hours per week), you need to divide 240 hours by 8 weeks.

Through the procedure explained above, you get the that the number of hours per week is the following:

$unit\ rate=\frac{240\ hours}{8\ weeks}\\\\unit\ rate=30\ \frac{hours}{week}$

(Notice that it is $30\ hours\ per\ week$ )
