If the price of an item is $20.00 with a sales tax of 4%, the total cost of the item is $20.80.

The total cost involves adding the price and the sales tax amount.

We can compute the total cost by determining the sales tax factor using the sales tax rate as follows:

The price of the item = $20.00

Sales tax = 4% = 0.04 (4/100)

The sales tax factor = 1.04 (1 + 0.04)

Thus, the total cost, including the price and the sales tax, is $20.80 ($20 x 1.04).

Answer:

8/9

Step-by-step explanation:

Solving

Step 1: Find the LCM of the denominators 2, 9, and 6:

Step 2: Convert each fraction into an equivalent decimal with denominator as 18.

Step 3: Add the fractions.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

8/9

Step-by-step explanation:

Take LCM of denominators 2, 9 & 6 = 18

1/2

[ 18/2 = 9 ]

Multiply 9 to both numerator and denominator,

1/2 * 9/9

= ( 1*9 )/( 2*9 )

= 9/18

2/9

[ 18/9 = 2 ]

Multiply 2 to both numerator and denominator,

2/9 * 2/2

= ( 2*2 )/( 9*2 )

= 4/18

1/6

[ 18/6 = 3 ]

Multiply 3 to both numerator and denominator,

1/6 * 3/3

= ( 1*3 )/( 6*3 )

= 3/18

( The denominator need to be same in order to add the fractions )

1/2 + 2/9 + 1/6

= 9/18 + 4/18 + 3/18

= ( 9 + 4 + 3 )/18

= 16/18

16 = 2*8

18 = 2*9

16/18

= ( 2*8 )/( 2*9 )

= 8/9

Answer:

square:48

triangle:16

circle:6.28

Step-by-step explanation:

square: b x h = base * height

triangle: 1/2 x bh = 1/2 x base x height

circle: 3.14 x r square = 3.14 x 4 x 1/2

4 because is radius square = 2 x 2 = 4

The expression that can be used to represent the total money earned is $12x - $15.

The first step is to determine the total amount earned this wek. This can be determined by multiplying the earnings per hour by the total hours/

Total earnings = $12 ×x = $12x

Answer:

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

Here is how to approach the problem:

We see that all our restrictions for all four answer choices are relatively the same with a couple of changes here and there.
One way to eliminate choices would be to look at which restrictions don't match the graph.

At x<-5, there is a linear function that does have a -2 slope and will intersect the x axis at -7. The line ends with an open circle, so any answer choice with a linear restriction of x less than or equal to -5 is wrong. This cancels out choices C and D.

Now we have two choices left.

For the quadratic in the middle, the vertex is at (-2,6) and the vertex is a maximum, meaning our graph needs to have a negative sign in front of the highest degree term. In our case, none of our quadratics left are in standard form, and instead are in vertex form.

Vertext form is f(x) = a(x-h)^2 + k.

h being the x-coordinate of the vertex and k being the y-coordinate.

We know that the opposite of h will be the actual x-coordinate of the vertex, so if our vertex is -2, we will see x+2 inside the parenthesis. This leaves option A as the only correct choice.

Answer:

  x = 15

Step-by-step explanation:

The solution to any problem is found by making use of the relations you know between the parts of the problem. Here, values of x relate to the arc measures around a circle. The relation you know is the sum of the arcs around a circle is 360°. Using this relation, you can write the equation ...

  7x° +4x° +6x° +7x° = 360°

The equation can be solved for x by making use of the rules of algebra.

  24x = 360 . . . . . . . . . . . . . . divide by °, collect terms

  x = 15 . . . . . . . . . . . . . . . . divide by 24
