Kayla went shopping for a new pair of sneakers. The listed price of the pair of sneakers was $20, but the price with tax came to $21.80. Find the percent sales tax.

Answers

Hello!

[tex]\large\boxed{9 \%}[/tex]

To find the percent tax, use the equation:

[tex]\text{ \% tax} = \frac{\text{ price after - initial price}}{\text{initial price}}[/tex]

Substitute in the given values:

[tex]\text{ \% tax} = \frac{\text{ 21.80 - 20}}{\text{20}} \\\\\text{ \% tax} = \frac{1.80}{20} = 0.09[/tex]

Multiply by 100 to find the percent tax:

[tex]0.09 * 100 = 9\%[/tex]

You pass the liquid to the next group, and then realize that your teacher wanted an answer in kilograms, not pounds. Complete the explanation of how you can adjust your answer without weighing the liquid again. Then give the weight in kilograms. If necessary, round your answer to the nearest tenth.


only right anwres

Answers

Answer:

7.7 pounds = 3.5 kilograms

Step-by-step explanation:

Given that,

Weight of a gallon of liquid = 7.7 pounds

We need to find weight in kilograms.

We must know the relation between pounds and kilograms and it is as follows :

1 kilogram = 2.20 pounds

or

1 pounds = (1/2.2) kilograms

7.7 pounds = (7.7/2.2) kilograms

= 3.5 kilograms

Hence, 7.7 pounds is equal to 3.5 kilograms.

Answer:

In a quadrilateral ABCD, ∠A = 100°, ∠B = 105° and ∠C = 70°, find ∠D.

Solution:

Here the sum of the four angles

or, ∠A + ∠B + ∠C + ∠D = 360°

We know, ∠A = 100°, ∠B = 105° and ∠C = 70°

or, 100° + 105° + 70° + ∠D = 360°

or, 275° + ∠D = 360°

∠D = 360° - 275°

Therefore,  = 85°

HELP ASAP

Answers

Answer:

Step-by-step explanation:

When the ladder is leaning against the wall, a 30-60-90 triangle is formed. The ladder acts as a 24-foot hypotenuse. Because the height is facing the [tex]30^{\circ}[/tex] angle, the height is half the hypotenuse (30-60-90 rules). If you forget the side rules for a 30-60-90 triangle, simply use basic trig on the right triangle:

solve for the y-intercept. Show your work! Then list the slope-intercept form of the line (-15,-17) (14,10)

Answers

Answer:

The line is y = 27/29x - 88/29The y-intercept is (0, -88/29)

Step-by-step explanation:

Given point:

(-15,-17), (14,10)

Slope-intercept form:

y = mx + b

Use slope formula:

m = (y₂ - y₁)/(x₂ - x₁)m = (10 - (-17))/(14 - (-15)) = 27/29

Use one of the points to find the y-intercept:

y = 27/29x + b10 = 27/29*14 + bb = (29*10 - 27*14)/29b = -88 /29

The line is:

y = 27/29x - 88/29

Answer:

slope for y intercept={10--17)/(14--15)=27/29

The diagram shows information about the final 70 seconds of a car journey. (a) Find the deceleration of the car between 60 and 70 seconds.

Answers

I have attached an image showing the diagram.

Answer:

-2 m/s²

Step-by-step explanation:

From the diagram, in decelerating from between 60 to 70 seconds, it moved from a velocity of 20 m/s to 0 m/s.

Thus, using Newton's first equation of motion, we can find the deceleration;

a = (v - u)/t

Time (t) = 70 - 60 = 10 s

Final velocity (v) = 0 m/s

Initial velocity (u) = 20 m/s

Thus;

a = (0 - 20)/10

a = -20/10

a = -2 m/s²

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

5k + (-7) = 13

Step 2: Solve for k

Simplify equation:                             5k - 7 = 13Addition Property of Equality:          5k - 7 + 7 = 13 + 7Simplify equation:                             5k = 20Division Property of Equality:           5k/5 = 20/5Simplify equation:                             k = 4

Step 3: Check

Plug in k into the original equation to verify it's a solution.

Substitute in k:                    5(4) + (-7) = 13Multiply:                               20 + (-7) = 13Add:                                     13 = 13

Here we see that 13 does indeed equal 13.

∴ k = 4 is the solution to the equation.
