scoundrel [369]

She will have to buy 8 jars for her to make a profit of $214

<h3>How to calculate the profit percent</h3>

If Alissa buys 6 jars of honey for $65, then;

Cost price = 6(65) = $390

If she sells 5 jars for $72, the selling price will be:

Selling price = 5(72) = $360

If she is to make a profit od $214

Profit = selling price - Cost price

214 = n(72) - 390
72n = 214 + 390
72n = 604
n = 8

Hence she will have to buy 8 jars for her to make a profit of $214

An experiment involves 16 participants. From these, a group of 4 participants is to be tested under a special condition. How man

zheka24 [161]

Answer:

43,680 ways.

Step-by-step explanation:

We have been given that an experiment involves 16 participants. From these, a group of 4 participants is to be tested under a special condition. We are asked to find the number of groups of 4 participants that can be chosen, assuming that the order in which the participants are chosen is irrelevant.

We will use permutations formula to solve our given problem.

$^nP_r=\frac{n!}{(n-r)!}$

For our given problem $n=16$ and $r=4$ .

$^{16}P_4=\frac{16!}{(16-4)!}$

$^{16}P_4=\frac{16!}{12!}=\frac{16*15*14*13*12!}{12!}=16*15*14*13=43,680$

Therefore, 4 participants can be chosen in 43,680 different ways.

The measure of one angle of a right triangle is 28∘ more than the measure of the smallest angle. Find the measure of the smalles

slava [35]

$\begin{gathered} x=\text{measure of the smallest angle} \\ 90+x+(x+28)=180 \\ 90+x+x+28=180 \\ 90+2x+28=180 \\ 2x+118=180 \\ 2x=180-118 \\ 2x=62 \\ x=\frac{62}{2} \\ x=31 \\ \text{The measure of the smallest angle is 31 \degree} \end{gathered}$
