How the sales tax calculator works
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.

What is the arc measure of minor arc AB on circle P in degrees?
Answer:
AB = 74°
Step-by-step explanation:
Minor arc AB is equal to the measure of the central angle APB , then
∠ APB = 360° - 286° = 74° , thus
minor arc AB = 74°
Arc measure of minor arc AB on circle P = 74 degrees
In the given circle,
Arc measure of major arc = 286 degree
Since we know that,
Measure of complete circle = 360 degree
Therefore,
Angle of minor sector = 360 - 286
= 74 degree
We also know that,
A circle sector is a segment or component of a circle made up of an arc and its two radii. A circle's sector can be compared to the form of a pizza slice. A sector is generated when two circle radii meet at both ends of an arc. An arc is merely a part of the circle's circumference.
Since,
Angle of sector = measure of arc
Hence,
Measure of minor arc = 74 degree.

Answer:
x ≥ -6
Step-by-step explanation:
The arrow is directing towards the right, in which the line contains number greater than -6. Moreover the circle on top of -6 is closed, proving that it is 'greater than or equal to'. (if it was greater than, the circle on top of the number would be open; the inner part of the circle wouldn't be shaded)
A bookmark has an area of 14 square centimeters and a perimeter of 18 centimeters. What are the dimensions of the bookmark?
Answer:
2 x 7
Step-by-step explanation:
a * b = 14
2a + 2b = 18
(a * b)/b = 14/b Dividing both sides by b
a = 14/b
Substitute a in the perimeter equation
2(14/b) + 2b = 18
28/b + 2b = 18
2b - 18 + 28/b = 0
Multiply both sides by b
2b^2 - 18b + 28 = 0
Divide both sides by two
b^2 - 9b + 14 = 0
The Factors of 14 include -2 and -7 which add up to -9
(b - 2) * (b - 7) = 0
This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.

Victor wants to buy fertilizer for his yard. The yard is 45 feet by 55 feet. The direction on the bag of fertilizer say that one bag will cover 1,250 square feet. How many bags of fertilizer should Victor buy to be sure that he covers the entire yard? 2 SEE ANSWERS
Answer: 2 bags
Step-by-step explanation:
First find the area of the yard.
The area given the units would be:
= Length * Width
= 45 * 55
= 2,475 ft²
Victor needs enough fertilizer to cover 2,475ft² but each bag covers only 1,250 ft².
The number of bags needed is therefore:
= 2,475 / 1,250
= 1.98
= 2 bags

True or false: if two parallel lines are cut by a transversal, each pair of alternate angles are congruent?
Answer: True.
If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles .

A baseball is hit in the air. Its height above the ground is described by the function
Ht=-16t^2+45t+5, where H(t) represents the height in feet of the ball t seconds after it is hit. To the nearest hundredth of a second, for how much time will the ball be in the air? Find algebraically.
help guys plz i suck at math, also step by step is needed Branliest is the reward like always
Answer:
2.9195
Step-by-step explanation:
To find the time we need to equate the function the zero and solve for t:
[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]
Using the general formula we have that:
[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]
then:
[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]
Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.

a) 1 foot
b) 5 feet
c) 96 feet

The x value of the vertex (highest point in this case) is found via -b/2a:
-80/-32 = 2.5
Plug 2.5 into the function:
h(2.5) = -16(2.5)² + 80(2.5)

Find the Equation of the lines.
A stock can go up, go down, or stay unchanged. How many possibilities are there if you own 3 stocks?
Answer:
There are 27 different possible outcomes.
Step-by-step explanation:
Assuming that you have 3 different stocks:
First, we need to find the number of events and the number of possible outcomes for each event.
Here we can assume that each one of the stocks is a event, and the number of possible outcomes for each one are:
Stock 1: 3 options (up, down, stay)
Stock 2: 3 options (up, down, stay)
Stock 3: 3 options (up, down, stay)
The total number of possible outcomes is equal to the product of the numbers of options for all the events.
Then the total number of possibilities is:
C = 3*3*3 = 27
If the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle, then what is cos(θ)?
Answer
cos(θ) = –313√(13)
Step-by-step explanation:
There is a rule we are to establish first to get the answer right.
If the terminal side of an angle θ in standard position intersects a unit circle A(x, y), then cos(θ) = x and sin(θ) = y.
Therefore, given that the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle:
cos(θ) = –313√(13)
What is the surface area of this triangular pyramid?
Answer:
48.25
Step-by-step explanation:
This is because when finding the area of a triangle it is known as base times height then divide by 2 and since the base is a triangle, multiply 4.3 times 5 which is 21.5 and divide by 2 which is 10.75 and for the top since its also a triangle multply 5x5 which is 25 divide by 2 whicih is 12.5, but there is 3 of them so multiply by 3 and you get 37.5, then add 37.5+10.75 to get 48.25 cm^2

The base of a rectangular pyramid is 13 inches long and 12 inches wide.
The height of the pyramid is 8 inches. What is the volume of the
pyramid?
Answer:
Area = 1/2 (Base) (Height)
Area = 1/2 (12 in) (8 kn)
Area = 1/2 (96 in)
Area = 48 in^2
Volume = (Area) (Length)
Volume = (48 in^3) (13 in)
Volume = 624 in^3
Answer:
V=L•W•H
3=13·12·8
3=416
=416³
Step-by-step explanation:
Finding the Volume of a Rectangular Pyramid
Your overall formula for finding the volume of these multi-faceted shapes is V = (l x w x h) / 3. Basically, your first step is finding the area of the base by multiplying length by width. Once you determine the area of the base, multiply that by the height.The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height.
If the cube has a side length s, then each pyramid has an s by s base and height s/2, and its volume is 1/6 the volume of the cube, which is 1/3 base times height. ... They are congruent, so have volume 1/3*base*height as the base is a square the side of the cube and the height is the side of the cube as well.Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.#CarryOnLearning

Can someone help me with this. Will Mark brainliest.
Answer:
The lines are perpendicular.
Step-by-step explanation:
If the lines are parallel, then the slopes are equal
If the lines are perpendicular, then the slopes are negative reciprocals
If neither of the above occur, then the lines are neither parallel or perpendicular.
y = 2x + 3 is in slope-intercept form, so the slope = 2
2y + x = 6
Solve for y: 2y = -x + 6
y = -1/2(x) + 3 so the slope = -1/2
2 and -1/2 are negative reciprocals, so the lines are perpendicular.
Note: Negative reciprocals have a product of -1. 2(-1/2) = -1
