<h3>Answer: 32</h3>

Explanation:

If a set has n items inside it, then there will be 2^n different subsets. This includes the original set itself (since any set is a subset of itself).

Here we have n = 5 items in the given set, so there are 2^5 = 32 different subsets.

For more information, I recommend looking up the term "power set".

* 4. A circle is divided into ten equal sectors.

Fiesta28 [93]

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

$= {360}^{0} \div 10$

$= {36}^{0}$

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

$= \frac{1}{n} \times 2\pi \times r$

$= \frac{1}{10} \times 2\ \frac{22}{7} \times 50$

$= 31.42 \: in$

If there is a maximum of 4,000 hours of labor available per month and 300 ping-pong balls (x1) or 125 wiffle balls (x2) can be p

andrey2020 [161]

Answer:

b. 300x1 + 125x2 < = 4,000

Step-by-step explanation:

Maximum of 4,000 hours

This means that the the total amount of labor has to be of at most 4,000, that is:

$T \leq 4000$

300 ping-pong balls (x1) or 125 wiffle balls (x2) can be produced per hour of labor

The total amount of labor is:

$T = 300x1 + 125x2$

Uniting the two equations:

$T \leq 4000$

$300x1 + 125x2 \leq 4000$

And thus the correct answer is given by option b.
