Answer:

1 sheet costs 1.6 cents

Step-by-step explanation:

The total cost of the toner is 40 dollars which is good for 10000 pages.

The cost of 500 sheets of paper is 6.00 dollars or 600 cents

500 sheets / 600 cents = 1 sheet /x         Cross Multiply

500 sheets  x = 600 cents                        Divide by 500

x = 600/500

x = 1.2 cents.

10000 sheets cost 40 dollars. = 4000 cents

1 sheet      costs x

10000/1 = 4000/x                          Cross multiply

10000*x = 1 * 4000                        Divide by 10000

x = 4000/10000

x = 0.4 cents.

Total Cost for 1 sheet = 0.4 cents + 1.2 cents

Total Cost for 1 sheet = 1.6 cents.

Find the output for each input of y = 2x – 1.
Jlenok [28]
1) False. You'd substitute -1 in for x, not y.
2) The scale factor is 1ft=14ft so true.
3) The first is a direct variation since y=6x is true.
4)The airplane would be 132ft in real life.
5) None of the functions made sense with the graph. I didnt really know what "thing" you were talking about on that one.

4. In a large community, 72% of the people are adults, 78% of the people have traveled outside the state, and 11% are adults who
natulia [17]

Answer:

a. The Venn diagram is explained in the attached word file.

0.61                                    

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

                                          Adult(A)        Not Adult (not A)        Total

Travel outside (T)                 610                170                               780

Not Travel outside (not T) 110                110                               220

Total                                 720                280                               1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

5x-2y=-6 3x-4y = -26​
snow_tiger [21]

For this case we must solve the following system of equations:

5x-2y = -6\\3x-4y = -26

We multiply the first equation by -2:

-10x + 4y = 12

We add the new equation with the second one:

-10x + 3x + 4y-4y = 12-26

We have different signs subtracted and the sign of the major is placed:

-7x = -14\\x = \frac {-14} {- 7}\\x = 2

Now we find the value of the variable "y":

3x-4y = -26\\3 (2) -4y = -26\\6-4y = -26\\-4y = -26-6\\-4y = -32\\y = \frac {-32} {- 4}\\y = 8

Thus, the solution of the system is given by:

(x, y) :( 2,8)

Answer:

(x, y) :( 2,8)
