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.
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.
Hope this helps.

2 people share 3 chocolate bars equally. Each chocolate bar is the same size.
About how much chocolate does each person get?
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 hope you understand.Help me to answer this pls
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?
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°.

Graph the line that passes through the points (0,-5) and (-5,_6)
Answer:
Step-by-step explanation:
First find the slope(m) between (0,-5) and (-5,-6)
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{-6-(-5)}{-5-0}[/tex] = [tex]\frac{-1}{-5}[/tex] = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex]x -5
I attached the graph. I used desmos.

the y-intercept, if the equation is written in slope-intercept form (y=mx+b) is represented by the 'b' and will be written as an ordered pair with an x-value of zero
Test Direction: Find the measure of <s. Write the answer on the space provided.
Answer:
16. 40°
17. 40°
18. 50°
19. 45°
20. 135°
Step-by-step explanation:
16. angles opposite to each other are equal
17. 180 - 140 = 40
18. 90 - 40 = 50
19. 65 + 70 = 135
180 - 135 = 45
20. 145 + 80 = 225
360 - 225 = 135

Calculate the equation of the following line.
Answer:
point-slope form: [tex]y+1=\frac{-3}{2}(x-3)[/tex]
slope-intercept form: [tex]y=\frac{-3}{2} x+\frac{7}{2}[/tex]
Step-by-step explanation:
find the slope of the line using two points on the graph, and then you can get your equation in point-slope form. if you need it in slope-intercept form, you can re-arrange your point-slope form equation.
hope this helps :)

Find the missing length of the longer leg in the
30° – 60° – 90° triangle.
short leg = 2
a 2v3
b7v2
с 67
d 475
Answer:
A) 2√3Step-by-step explanation:
Side ratios of 30°-60°-90° triangle:
a : b : c = 1 : √3 : 2Given:
a = 2Find b:
2 : b = 1 : √3b = 2*√3/1b = 2√3Correct choice is A
So
We know the ratio
x:y:z=30:60:90=1:√3:2Now
x=2
So
2:y=1:√3y=2√3And
2:z=1/2z=4Option A

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 %
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
