Answer:

C) 2400

Step-by-step explanation:

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

Computers = 10

Printers = 3

Scanners = 5

Telephone = 8

Copiers = 2

Possible outcome = 10 x 3 x 5 x 8 x 2 = 2400

Answer:

$46.2^o$

Step-by-step explanation:

<u><em>The correct question is</em></u>

If b = 9 and c = 13, what is the measure of ∠A? (round to the nearest tenth of a degree)

The picture in the attached figure

we know that

In the right triangle ABC

$cos(A)=\frac{b}{c}$ ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(A)=\frac{9}{13}$

using a calculator

$A=cos^{-1}(\frac{9}{13})=46.2^o$

Answer: $x=\frac{6}{-3y+8}$

Step-by-Step Explanation:

Let's solve for $x$ .

$\frac{x-2}{3y-5} =\frac{x}{3}$

Step 1: Multiply both sides by $3y-5$ .

$x-2=\frac{3xy-5x}{3}$

Step 2: Multiply both sides by $3$ .

$3x-6=3xy-5x$

Step 3: Add $-3xy$ to both sides.

$3x-6+-3xy=3xy-5x+-3xy$

$-3xy+3x-6=-5x$

Step 4: Add $5x$ to both sides.

$-3xy+3x-6+5x=-5x+5x$

$-3xy+8x-6=0$

Step 5: Add $6$ to both sides.

$-3xy+8x-6+6=0+6$

$-3xy+8x=6$

Step 6: Factor out variable $x$ .

$x(-3y+8)=6$

Step 7: Divide both sides by $-3y+8$ .

$\frac{x(-3y+8)}{-3y+8}=\frac{6}{y-3y+8}$

$x=\frac{6}{-3y+8}$

Answer:

$x=\frac{6}{-3y+8}$

PLEASE help me with this question and I WILL love you forever But yeah please help me with the question.And EXPLAIN in words how

Well on this problem recall area of a rectangle is defined by:

A = lw our w = 1/6 and our l = (x + $\frac{2}{3}$ ) we have let 'x' represent our original length.
$(x + \frac{2}{3} )( \frac{1}{6} )= \frac{11}{72}$
$\frac{1}{6} x+ \frac{2}{18} = \frac{11}{72}$
12x + 8 = 11
12x = 11 - 8
12x = 3
x = $\frac{3}{12} = \frac{1}{4}$ So our original length is $\frac{1}{4}$
