Answer:

10

Step-by-step explanation:

Use the PEMDAS rule.

20 - 3 * 6 + 8

= 20 - 18 + 8

= 20 - 10

= 10

When we carry out the operation 20 - 3 × 6 + 8 the result obrained is 10

The meaning of BODMAS is given below:

The above pattern tells us exactly what sign to carry out 1st when we have more than one signs in an expression.

Based on the cost of her items, if Kim hands over $100, she will get back $9.85.

The total that Kim will pay includes the cost of all three items as well as the sales tax.

The total cost of the three items is:

= Blouse + Skirt + Purse

= 17.16 + 28.19 + 35.14

= $80.49

The total including the sales tax will be:

= Cost + (Cost x Sales tax)

= 80.49 + (80.49 x 12%)

= $90.15

The change she will get is:

= 100 - 90.15

= $9.85

In conclusion, Kim will get a change of $9.85.

Step-by-step explanation:

The perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

The coordinates are given as:

(−4,4), (−4,1), and (−8,−4).

Calculate the distance between the vertices using:

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]

So, we have:

[tex]AB = \sqrt{(-4 + 4)^2 + (4-1)^2} = 3[/tex]

[tex]BC = \sqrt{(-4 + 8)^2 + (1+4)^2} = \sqrt{41[/tex]

[tex]AC = \sqrt{(-4 + 8)^2 + (4+4)^2} = \sqrt{80[/tex]

The perimeter is the sum of the side lengths.

So, we have:

[tex]P = 3 + \sqrt{41} + \sqrt{80}[/tex]

Expand

[tex]P = 3 + \sqrt{41} + 4\sqrt{5}[/tex]

Hence, the perimeter of the triangle is [tex]3 + \sqrt{41} + 5\sqrt{5}[/tex] units

Answer:

2 11/12

Step-by-step explanation:

The average of 2 ⅓ and 3 ½ is 2 ‌11⁄12‌. To find the average, find the sum of the fractions and divide by 2.

2 ⅓ + 3 ½ = ‌7⁄3‌ + ‌7⁄2 = ‌14⁄6 + ‌21⁄6 = ‌35⁄6 or 5 5⁄6

5 5⁄6 ÷ 2 = 35⁄6 × 1⁄2 = 35⁄12 or 2 11⁄12

The average of 2⅓ and 3½ is 2 11/12

2⅓ + 3½ = 7/3 + 7/2 = 14/6 + 21/6 = 35/6 or 5/6

5 5/6 ÷ 2 = 35/6 × 1/2 = 35/12 or 2 11/12

Finding the Average

Average refers to the sum of the values divided by the count. Therefore, the steps to follow to find the average are below:

Add the given values.

Divide the sum by the count of values.

Equation:

(2 1/3 + 3 1/2) / 2 = ?

Solution:

(2 1/3 + 3 1/2) / 2 = ?

* Change the mixed numbers to improper fractions.

= (7/3 + 7/2) / 2

* Add the fractions. Find the LCD.

= (14/6 + 21/6) / 2

= ( 35/6 ) /2

To divide change the sign to multiplication, The give the reciprocal of the second fraction

= 35/6 × 1/2

The table is an illustration of a linear function.

The description of the charges is: A)  The ride requires a $14 initial fee, plus 50 cents per mile driven

The base fee is the charges, when the number of miles is 0

From the table;

y = $14, when x = 0

So, the base fee is $14

Next, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the table, we have:

[tex]m = \frac{16.5 - 14}{5-0}[/tex]

[tex]m = \frac{2.5}{5}[/tex]

[tex]m = 0.5[/tex]

The above means that:

The cost per mile is $0.5 (i.e. 50 cents)

Hence, the description of the charges is: A)  The ride requires a $14 initial fee, plus 50 cents per mile driven

Table:

1: f(x) = 5

2: f(x)= 6

5: f(x) = 9

Points: (1,5), (2,6), and (5,9)

Step-by-step explanation:

1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.

Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.

2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:

Therefore, the points are (1,5), (2,6), and (5,9).
