You are ordering pizzas. The pizza cost $18. The sales tax is 6%, and you give a 15% tip. What is the total?
Answer:
$21.94
Step-by-step explanation:
I'm not sure how many pizzas were ordered, but let's say you just got one large pizza that was $18.
First, the sales tax - 6%
$18 + 6% = $19.08
Then you give a 15% tip.
$19.08 + 15% = $21.94
A band that will be the opening act for a concert charges a $500. 00 flat fee as well as 10% of all profits from ticket sales. If the band earns $1,200, how much was made in total ticket sales for the show?.
Using the profit concept to find the ticket sale, then the money made in ticket sales for the show is $7000.
What is profit?The money that you gain by selling something.
Given
A band that will be the opening act for a concert charges a $500 flat fee as well as 10% of all profits from ticket sales.
They earned the profit will be
1200 - 500 = 700
They earned a profit is $700.
$700 is 10% of ticket sales. Then the money made in total ticket sales for the show will be
[tex]\rm Ticket\ Sale = \dfrac{700}{0.1}\\\\Ticket\ Sale = 7000[/tex]
The money made in total ticket sales for the show is $7000.

Answer:
A. 1.06
B. $6,784
Step-by-step explanation:
I = A - P = $384.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 6400(1 + (0.06 × 1)) = 6784
A = $6,784.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.

If ⅙ of a roll of wallpaper covers ¼ of the wall. How many rolls of paper are needed to cover 4 walls?
Answer:
if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6
we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls
If three times a number is increased by 24, the result is 16 less than seven times the same number. Find the number.
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10

Step-by-step explanation:
A triangle has vertices at (−2, −2), (−2, −5), and (−4, −5). The triangle is translated 2 units to the right and rotated 90° clockwise about the origin. What are the coordinates of its image?
( , ), ( , ), ( , ) → ( , ), ( , ), ( , ),
Step-by-step explanation:
translated (shifted) 2 units to the right (positive x direction) creates the points
(-2 + 2, -2) = (0, -2)
(-2 + 2, -5) = (0, -5)
(-4 + 2, -5) = (-2, -5)
and now we rotate these points 90° clockwise around the origin.
that means a positive x turns into a negative y, a negative y into a negative x, a negative x into a positive y, and a positive y into a positive x.
and a 0 just trades places.
therefore,
(0, -2) becomes (-2, 0)
(0, -5) becomes (-5, 0)
(-2, -5) becomes (-5, 2)
so, overall
(-2, -2) becomes (-2, 0)
(-2, -5) becomes (-5, 0)
(-4, -5) becomes (-5, 2)

• The middle angle is triple the smallest angle..
a) write an equation to model the relationship
b) solve the equation and then determine the measure of each angle. Sketch the triangle and label the angle measures.
Answer:
a) a +8a +3a = 180°
b) 15°, 45°, 120°

o.
To finish his construction, Zahid needs to draw segments DF,V, and
The joining of each three, two penultimate points on the circumference
of the circle, without intersection gives an equilateral triangle.
Response:
The segments that Zahid needs to draw are; DF, BF, and BDHow can the equilateral triangle be constructed from the given construction on the circle?The assumption can be taken that, the steps used to construct the
equilateral triangle inscribed in the circle by marking along the
circumference of the circle at 6 points using the radial length.
Therefore;
The lengths of the chords formed by joining a marked points to another point such that one marked point is between the two are equal.
Which gives;
The length of the chord, DF = The length of the chord, BF = The length of the chord, BD
Given that the joining DF, BF and BD forms a triangle, and DF = BF = BD, we have;
