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.

The local farms market sells peppers at five for 4.75 what is the constant of proportionality
Answer:
4.75
Step-by-step explanation:
Each pepper or product of pepper costs $4.75
So the unit rate is 4.75/pepper
The unit rate is considered as the slope of the line, or also known as the constant or proportionality. As the Number of peppers increase, the price increases proportionally.
The constant of proportionality is 4.75

Explain what is Translation, Rotation, and Reflection.
Answer:
A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.
A rotation means turning around a center.
A reflection is a transformation representing a flip of a figure.
Answer:
See below!
Step-by-step explanation:
Translation: "Sliding": moving a shape without rotating or flipping it.
The shape still looks exactly the same, just in a different place.
Rotation: A circular movement.
Rotation has a central point that stays fixed and everything else moves around that point in a circle.
A "Full Rotation" is 360°
Reflection: Coordinate plane: A point reflected across the x or y axis, or x and y axis.
Coordinate plane, Shapes: A shape that is reflected across the x or y axis, or x and y axis. (Staying at the same coordinates).
Slopes: A slope that is reflected across the x or y, or x and y axis.

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
Can someone please help me out with this ??? I’d appreciate it so much
Answer:
(0, 1)
Step-by-step explanation:
So with the 2 equations you can either choose which to start with but you need to make the X or Y the opposite from the other equation.
1.
4x + 2y = 2 --> 1( 4x + 2y = 2)
3x - y = -1 --> 2( 6x - 2y = -2)
--
6x + 4x = 10x
2y - 2y = 0 (forced to get rid of)
2 - 2 = 0
Left with:
10x = 0 (Divide both sides by 10 to get X alone)
x = 0
-----------------------------------------------------------
(Choose any ORIGINAL equation)
4x + 2y = 2
4(0) + 2y = 2 (substitute)
Left with:
2y = 2 (divide both sides by 2 to get Y alone)
y = 1
-------------------------------------------------------------
Optional:
Chose the other equation (the oposite from above)
Substitute X and Y in 3x - y = -1
3(0) - (1) = -1
Left with: -1 = -1 (check)

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°.

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 )

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.
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
