Hoochie [10]

Answer:

<h2>a) 120 ways</h2><h2>b) 6 unique ways</h2>

Step-by-step explanation:

The question will be solved using the permutation formula since are arranging. <u>Permutation deals with arrangement.</u>

If there we are to arrange n objects taking 'r' at a time, this can be done in nPr ways.

nPr = \frac{n!}{(n-r)!}

a) If you therefore have 6 reindeer, Prancer, Rudy, Balthazar, Quentin, Jebediah, and Lancer, and you want to have 3 fly your sleigh. Since they are in a single file line, This can be done in 6P3 number of ways.

6P3 = \frac{6!}{(6-3)!}\\ 6P3 = \frac{6!}{3!}\\ 6P3 = \frac{6*5*4*3!}{3!} \\6P3 = 6*5*4\\6P3 = 120\ ways

b) The number of unique ways to arrange the letters in the word DEN is 3! ways since there are only 3 letters in the word.

3! = 3*2*1

3! = 6ways

Use the triangle to answer the question.Find the value of x. Round to the nearest degree.
AlexFokin [52]

Given:

base = 16

hypotenus = 21

\cos \theta=\frac{base}{hypotenus}

Angle = x

\begin{gathered} \cos x=\frac{16}{21} \\ \cos x=0.76 \\ x=\cos ^{-1}(0.76) \\ x\approx40 \end{gathered}

The value of x is 40 degree.

If the side of a rectangular prism is doubled, how would this affect the area? How about the volume?
professor190 [17]

Answer:

Step-by-step explanation:

The area will be increased by 4 times  and volume will be increased by 8 times

Area of rectangular prism = 2 (lb+bh +hl)

When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)

                                                     = 4 * 2 (lb+bh +hl)

Volume  of rectangular prism = lbh

When sides are doubled,  Volume = 2l * 2h * 2b = 8 lbh

What is rounding for math
Sedaia [141]

Answer:

Step-by-step explanation:

Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.
