A computer company has a special going in which all customers receive a free monitor and scanner with the purchase of a new comp

uter. It costs the company $393.29 to make each computer, $151.44 to make each monitor, and $46.39 to make each scanner. The computers are then sold, with the free monitor and free scanner, for $1,196.91 each. Approximately how much profit will the company make if 408 customers take advantage of their special? (Round to the nearest 50 dollars.) A. $300,000.00 B. $550,000.00 C. $240,000.00 D. $380,000.00

Answer:

2160

Step-by-step explanation:

Given : At a computer​ store, a customer is considering 10 different​ computers, 6 different​ monitors, 9 different printers and 4 different scanners. We assume that each of the components is compatible with one another and that one of each is to be​ selected. then by Fundamental counting principle , the number of different computer systems possible is given by :-

10x6x9x4= 2160

Hence, the number of different computer systems possible= 2160The Fundamental Counting Principle is a technique in Mathematics to calculate the number of possible outcomes by multiplying the events together .

abruzzese [7]

Answer:

42.9%

Step-by-step explanation:

-42.857142857142854 is the exact number. Rounded to 42.9% thus b: is the correct answer.

Formula:

[(120 - 210) / 210] × 100% = -0.42857142857142855 × 100% = -42.857142857142854%

Use the linear combination method to solve the system of equations. Explain each step of your solution.
Ne4ueva [31]

Answer:

The value of x is - 3  And The value of y = - 2

Step-by-step explanation:

Given equation as :

3 x - 8 y = 7          ......A

x + 2 y = - 7          ......B

<u>Applying Linear combination method :</u>

A linear combination method in which steps are taken to make both equation coefficient as like terms to get the value of variable .

<u>Step 1 </u>

multiply the equation B with 4

I,e 4 × ( x+ 2 y ) = - 7 × 4

or, 4 x + 8 y = - 28       ......C

<u>Step 2</u>

Arrange  equation A and C in column

So , 3 x - 8 y = 7          .

      4 x + 8 y = - 28

<u>Step 3</u>

Add Eq 3 with Eq 1

I.e (   4 x + 8 y ) + (  3 x - 8 y ) = 7 - 28

Or. ( 4 x + 3 x ) + ( 8 y - 8 y ) = - 21

Or,  7 x + 0 = - 21

∴     x =  - \frac{21}{7} = - 3

Put the value of x in eq A ,  to get the value of y

So , 3 × ( - 3 ) - 8 y = 7

Or,  - 9 - 8 y = 7

Or, 8 y = - 9 - 7 = - 16

∴     y =   \frac{- 16}{ 8} = - 2

Hence The value of x is - 3  And The value of y = - 2   Answer

One leg of a 45 - 45 - 90 triangle measures 12 centimeters what is the length of the hypotenuse
adelina 88 [10]
The angles of the triangle are given as to have measures of 45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:

c² = a² + b²

c² = 2a²

4² = 2a²

a = 2√2

Hope this answers the question.

What are the solutions to the equation (x + 2)^2 = 49?
Mekhanik [1.2K]

Answer:

X= 5, -9

Step-by-step explanation:

(X+2)² =49

Expand the bracket,


(X+2) (X+2)= 49

Apply the distributive property;

X(X+2) +2 (X+2) =49

X²+2X+2X+4=49

X²+4X+4=49

Move 49 to the left side of the equation;

X²+4X+4-49=0

X²+4X-45=0

Apply Factorisation method;

Consider the form

a²+bx+c=0  

Find two numbers whose sum is equal to b and whose product is equal to c.
Comparing with our equation;

B =4 and C =45

We can use 9 and -5, this is because ;

9+(-5)=4 and 9*(-5)= 45.

Replace X +4X-45=0 with (X-5) (X+9)=0

Therefore;

X-5=0

X+9=0

Moving to the left side of the equation;

Therefore X= 5 and -9
