Answer:

It will take 8 minutes

Step-by-step explanation:

3 hours 28 minutes = how many minutes

3 hours * 60 minute/hour = 180 minutes

3 hours 28 minutes =180 +28 = 208 minutes


We can use proportions to solve

26 miles               1 mile

---------------    =   --------------

208 minutes           x minutes

Using cross products

26 * x = 208 *1

26x = 208

Divide by 26

26x/26 = 208/26

x = 8

It will take 8 minutes

Please help on two math questions. I don’t understand how to do them.

When you represent intervals on the number line, you're including full dots, excluding empty dots, and you're considering numbers highlighted by the line.

In the first case, you've highlighted everything before -2 (full dot, thus included), and everything after 1 (empty dot, excluded). So, the set would be

x\leq -2 \lor\ x>1

or, in interval notation,

(-\infty,-2]\cup (1,\infty)

In the second case, you are looking for all numbers between -3 and 5. This interval is symmetric with respect to 1: you're considering all numbers that are at most 4 units away from 1, both to the left and to the right.

This means that the difference between your numbers at 1 must be at most 4, which is modelled by

|x-1|\leq 4

where the absolute values guarantees that you'll pick numbers to the left and to the right of 1.

Find the measure of a central angle that intercepts an arc of 81.5 cm in a circle whose radius is 16.3 cm.
Paul [167]

Answer:

5 rad

Step-by-step explanation:

Recall that the length of an arc of circumference is given by the formula:

Arc\,Length=\theta\,*\,radius, where \theta is the subtended angle [in radians] from the circumference's center.

Therefore in this case, you know the arc length (81.5 cm), and the radius (16.3 cm), and can solve for the angle \theta using the above equation as shown below:

Arc\,Length=\theta\,*\,radius\\81.5\,cm = \theta\,*\,16.3\,cm\\\frac{81.5}{16.3} = \theta\\\theta=5\,rad
