The sales tax for an item was $26.60 and it cost $380 before tax. Find the sales tax rate. Write your answer as a percentage.

Answers

Answer:

7% sales tax

Step-by-step explanation:

Given the following question:
Sales tax = $26.60
It costs $380 before tax

In order to find the answer, we simply find a random percentage of the original cost before tax.

[tex]\frac{7\times380}{100} =2660\div100=26.6=26.60[/tex]
7% sales tax rate.

Find the missing length of the longer leg in the
30° – 60° – 90° triangle.
short leg = 2
a 2v3
b7v2
с 67
d 475

Answers

Answer:

A) 2√3

Step-by-step explanation:

Side ratios of 30°-60°-90° triangle:

a : b : c = 1 : √3 : 2

Given:

a = 2

Find b:

2 : b = 1 : √3b = 2*√3/1b = 2√3

Correct choice is A

So

We know the ratio

x:y:z=30:60:90=1:√3:2

Now

x=2

So

2:y=1:√3y=2√3

And

2:z=1/2z=4

Sorry, I am just dum, What would be the area of this triangle? It is in demos and that last line underlined was just added to complete the triangle or else there would be no bottom line for the triangle.

Answers

Answer:

A = 5 units²

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = AC = 5 and h = AB = 2 , then

A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 2.5 × 2 = 5 units²

To convert celsius to Fahrenheit:

To convert Fahrenheit to celsius:

To convert kelvin to celsius:

To convert Fahrenheit to kelvin :

The parking garage at the airport has 4750 empty parking spaces and 250 full parking spaces. What percent of the spaces in the garage are empty write your answer using a %

Answers

Answer:

I'd say around 95% or 94.737%

Step-by-step explanation:

4750 - 250 = 4500

4750/250 = 1/19

1/19 = 0.052 or close to 5%

4750 x 94.737% = 4500.0075

2 people share 3 chocolate bars equally. Each chocolate bar is the same size.
About how much chocolate does each person get?

Answers

Answer:

1.5 Pieces

Step-by-step explanation:

If you divide 3 chocolate bars by 2 people it will evenly be distributed by 1.5

Answer:

Just divide it.

Step-by-step explanation:

Take each bar height as 10. There are 3 bars. So the total height is 30. But there is 2 persons, so dividing it will result 15. So according to this assumed answer, I will say you will have to do this :

Give one bar to each of them and the bar should be divided in half, provided that  two parts should be there as well as both parts of it should be 5 in height.

So, the upper part was an assume. This time, you mentioned no heights, so I will do it with equation process.

(meaning of each variable)

people = x

chocolate bar = 3

2x ( since 2 people) = 3 ( three chocolate bars )

2x=3

x=3/2

x=1.5 ( one and half )

i) How do you find the sum of the angle measures of any convex polygon?

ii) If the polygon is regular, how do you find the measure of each interior angle in the polygon?

iii) How do you find the sum of the exterior angle measures of any convex polygon?

iv) If the polygon is regular, how do you find the measure of each exterior angle in the polygon?

Answers

Answer:

1) The sum of interior angles of a convex polygon is equal to (n-2) × 180°, where 'n' is the number of sides of the polygon.

2) A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.

4) Irrespective of the number of sides of a regular polygon, the measure of each exterior angle is equal and the sum of the measure of all the exterior angles of the regular polygon is equal to 360°.
