The sales tax on this printer is $20.94

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

Given that, the price of a printer is $349.00 having a 6% sales tax.

Sales tax = 6% of $349.00

$349.00 x 0.06 = $20.94

Hence, the sales tax on this printer is $20.94

Answer:

a: [tex]\$ 14[/tex] or [tex]14[/tex] dollars

b: [tex]\$0.57[/tex] or [tex]57[/tex] cents

c: [tex]\$14.57[/tex] or [tex]14[/tex] dollars and [tex]57[/tex] cents

Step-by-step explanation:

a: We have [tex]2[/tex] [tex]\$5[/tex] bills, which have a total value of [tex]2*5= \$10[/tex]. We also have [tex]4[/tex] [tex]\$1[/tex] bills, which have a total value of [tex]4*1= \$4[/tex]. Adding these up gives us  [tex]10+4= \bf \$14[/tex] or [tex]\bf 14[/tex] dollars for the total value of the bills.

b: Remember that a quarter is worth [tex]\$0.25[/tex], a nickel is worth [tex]\$0.05[/tex], and a penny is worth [tex]\$0.01[/tex]. Therefore, [tex]2[/tex] quarters are worth [tex]2*0.25=\$0.50[/tex], [tex]1[/tex] nickel is worth [tex]1*0.05=\$0.05[/tex], and [tex]2[/tex] pennies are worth [tex]2*0.01=\$0.02[/tex]. Adding these up gives us [tex]0.50+0.05+0.02=\bf \$0.57[/tex] or [tex]\bf 57[/tex] cents for the total value of the coins.

c: We know that the total value of the bills is [tex]\$ 14[/tex] (or [tex]14[/tex] dollars) from Part A and the total value of the coins is [tex]\$0.57[/tex] (or [tex]57[/tex] cents) from Part B. Therefore, we have [tex]14+0.57=\bf \$ 14.57[/tex] in total or [tex]\bf 14[/tex] dollars and [tex]\bf 57[/tex] cents.

Answer:

4/5

Step-by-step explanation:

Find 2 defined points like (-2,0)(3,4) in other to reach the point (3,4) from (-2,0) it moves 5 times front and 4 times up  

Up is Y value

Front is X value

To solve it is adding the value that you get from moving it in this case

5 front X equals to 5

4 up Y equals to 4

Then is 4/5

because the formula is Y/X

Answer:

10 and 7 are the numbers

Step-by-step explanation:

Let the number be x and y, ATQ, x+y=17 and x-y=3, solving it we will get x=10 and y=7

The sum of two numbers is 17 and their difference is 3.

Let's define the two numbers as x and y.

Sum of two numbers is 17

x + y = 17

Their difference is 3

x - y = 3

-----------------------------------------

Solve for x

x + y = 17

x = 17 - y

now that we have x, substitued x into x - y = 3

x - y = 3

17 - y - y = 3

17 - 2y = 3

-2y = -14

y = 7

we have y, 7, now let's substitue that into one of the equations to find x

x - y = 3

x - 7 = 3

x -7 + 7 = 3 +7

x = 10

the numbers are 10 and 7

Step-by-step explanation:

x + y + n = 576

When something is 25% larger than something else, the effect is the same as multiplying by 1.25. Let's try it with an example

20 + (25/100)* 20 = 20 + 500/100 = 20 + 5 = 25. Now if you multiply 20 * 1.25 you get 25 which is just what you should get.

n = 1.25(x + y)                    Divide by 1.25

n / 1.25 = x + y                   Substitute n / 1.25 for x + y in the above equation    

n/1.25 + n = 576                Multiply everything by 1.25  

n + 1.25n = 576*1.25         Combine the left to get 2.25

2.25 n = 576 * 1.25           Divide by 2.25

n = 576*1.25 / 2.25    

n = 320

Answer:

If it's parallel, then it has the same slope.

Find the slope from the two coordinates and compare the slope to see which ones are right.

Answer:

18245

Step-by-step explanation:

We have to use L.C.M,

L.C.M(20,24,32,38)

2|20,24,32,38

2| 10 ,12 ,16 ,19

2| 5 , 6 , 8 , 19

2| 5 , 3 , 4 , 19

2| 5 , 3 , 2 , 19

L.C.M = 2 x 2 x 2 x 2 x 2 x 2 x 5 x 3 x 19

          = 18240

Now for each case remainder is 5,

So the number is 18240+5

=> 18245

The coordinates of the image of J (−5, −1) after the translation (x, y) → (x − 2, y) will be (−7, −1). Then the correct option is D.

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

The rule of the translation is given below.

(x, y) → (x − 2, y)

The coordinates of the image of J (−5, −1). Then the location of the point J after the translation will be

(x, y) → (x − 2, y)

(−5, −1) → (−5 −2, −1)

(−5, −1) → (−7, −1)

The coordinates of the image of J (−5, −1) after the translation (x, y) → (x − 2, y) will be (−7, −1). Then the correct option is D.

Answer:

y = 3 for 0 <= x < 4

y = 7 for 8 <= x < 12

y = 9 for 12 <= x < 16

y = 11 for 16 <= x < 20

x represents the number of years of employment.

for example, when x = 4, the employee has been there a full 4 years and is entitled to an additional 2 dollars wage to make the total wage equal to 3 + 2 = 5.

your graph stops at x = 16 because that's the number of years being considered.

at x = 16, the wage will be 11 dollars.

the closed circle indicates the value of y is valid at that value of x.

an open circle indicates the value of y is not valid at that value of x.

for example, when x = 4, y = 3 is not valid anymore, but y = 5 is.

on the 16th year of employment, the employee is entitled to an additional 2 dollars wage and starts earning at a wage of 11 dollars.

at employment (x = 0), the employee starts earning a wage of 3 dollars.

at 4 years (x = 4), the employee starts earning a wage of 5 dollars.

at 8 years (x = 8), the employee starts earning a wage of 7 dollars.

at 12 years (x = 12), the employee starts earning a wage of 9 dollars.

at 16 years (x = 16), the employee starts earning a wage of 11 dollars.

x represents a full year of employment.

y represents the wage the employee is entitled to earn.
