. Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?
Answer:
$1023.74
Step-by-step explanation:
Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?
Step 1
We find the new price after the discount.
Discount = % Discount × Current price
= 30% × $1299.99
= $389.997
The new discounted price =
$1299.99 - $389.997
= $909.993
Step 2
We calculate the Sales tax
The city Joan lives in has a 12.5% sales tax.
Hence,
The sales tax =
12.5% × $909.993
= 12.5/100 × $909.993
= $113.749125
Step 3
The total cost of the TV is calculated as:
Sales Tax + Discounted price
= $113.749125 + $909.993
= $1023.742125
Approximately = $1023.74
The total cost of the TV = $1023.74

Simplify the following expression.
3(2x+7)
is this right!? correct answer only!! ANSWER ASAPPP i put -2/8
Answer:
Yes, but can be simplified to [tex]-\frac{1}{4}[/tex]
Step-by-step explanation:
Since slope is the formula to determine the equation of a line, we use,
[tex]\frac{rise}{run}[/tex]
In this sense, we can see that the rise is -2
The run, or how far along the x-axis the line goes until it reaches its desired point is 8.
Although you are correct in the [tex]-\frac{2}{8}[/tex], don't forget to use your GCF to determine how low the fraction can go. (GCF or greatest common factor of 2 in this case) to get [tex]-\frac{1}{4}[/tex]
I hope this answer finds you well, and I would be happy to help you again in the future! :D

A square has two lengths, (6x-1)cm and (4x+6)cm.
What is the length of one side of the square, the answer must be written in the form, side=.......cm
9514 1404 393
Answer:
side = 20 cm
Step-by-step explanation:
We assume the two given lengths are sides of the square, so are equal to each other.
6x -1 = 4x +6
2x = 7
We could find x = 3.5, but we can use 2x, too.
(2)(2x) +6 = 2(7) +6 . . . find the side length
4x+6 = 20 . . . . the side length of the square
__
side = 20 cm

The parabola y-- (x – 3)2 + 6 has its focus at (3, 1). Determine and state the equation of the directrix.
Answer: you got to Find the focus of a parabola given its equation. If you have the equation of a parabola in vertex form , then the vertex is at and the focus is . Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

A jar contains only pennies, nickels, dimes, and quarters. There are 16 pennies, 29 dimes, and 24 quarters. The rest of the coins are nickels. There are 96 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
Answer:
the answer is 67 coins are not Nickels
Step-by-step explanation:
29+24+16=67 so there is 27 Nickels in the jar

whats the question
ill edit the answer in you put the question
Answer:
m∠3 = 78
Step-by-step explanation:
Okay, since a triangle has 3 sides, we only need to find the measure of m∠3.
A triangle is made up of 180 degrees, so we can make an equation with 180 as what the equation is equal to.
Since m∠1 = 70, and m∠2 = 32, we will add those together with a variable x,
70+32+x=180
70 plus 32 is 102.
102+x=180
To get 102 to the other side we need to do the opposite of addition, which is subtraction.
180-102=78
So the answer is 78.

A 156-inch board is cut into two pieces. One piece is three times the length of the other. Find the
length of the shorter piece.
The shorter piece is inches long.
Answer:
The shorter piece is 39 inches long.
Step-by-step explanation:
ratio = 3 : 1
3+1=4
156/4 = 39
just to check:
39 x 3 = 117 (the lenght of the longer piece)
117 + 39 =156

What is the measure of angle x?
Answer:
43
Step-by-step explanation:
Since right angles are 90 degree. 90 - 47 = 43
It looks mirrored, so I am guessing the 47 degree is also at the bottom.

Answer:
y = 2x - 3
Yes, your answer is correct.
Step-by-step explanation:
First, find the slope of the two points by using the slope formula:
y2 - y1
m = -------------
x2 - x1
13 - 5
m = -------------
8 - 4
8
m = ------- = 2
4
To find the y-intercept, plug in values into the slope-intercept formula:
y = mx + b
Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):
5 = (2) (4) + b
5 = 8 + b
-3 = b
b = -3
So, putting everything into the slope intercept formula:
y = 2x - 3
The box office at a theater is selling tickets for a series of rock concerts. So far, they have sold 53 balcony tickets and 94 general admission floor tickets for Friday's show, for a total of $4,482 in receipts. For Saturday's show, 53 balcony tickets and 47 general admission floor tickets have been sold, equaling $3,354 in receipts. How much does each ticket cost?
The box office sold 360 tickets to a concert at
the college. The total receipts were $4,170. General
admission tickets cost $15 and student tickets cost $10.
How many of each kind of ticket was sold?
Answer: 114 general admission tickets and 246 student tickets were sold.
Step-by-step explanation:
Let x represent the number of general admission tickets that were sold.
Let y represent the number of student tickets that were sold.
The box office sold 360 tickets to a concert at the college. It means that
x + y = 360
General admission tickets cost $15 and student tickets cost $10. The total receipts were $4170. It means that
15x + 10y = 4170- - - - - - - - -1
Substituting x = 360 - y into equation 1, it becomes
15(360 - y) + 10y = 4170
5400 - 15y + 10y = 4170
- 15y + 10y = 4170 - 5400
- 5y = - 1230
y = - 1230/-5
y = 246
x = 360 - y = 360 - 246
x = 114
Answer:
Step-by-step explanation:
Subtract 2nd equation from the first
53b+94g-53b-47g=4482-3354
47g=1128
g=24, using this value in 53b+94g=4482 gives you
53b+94(24)=4482
53b+2256=4482
53b=2226
b=43
So general admission tickets cost $24 and balcony tickets cost $43.
Joshua has a 32 ounce flavored water. He drinks 30 ounces. Enter the percentage of ounces Joshua has left of his flavored water. Round here answer to the nearest hundredth.
Answer: 6.25%
Step-by-step explanation:
From the question, we are informed that Joshua has a 32 ounce flavored water and that he drinks 30 ounces.
The amount of water he has left will be:
= 32 - 30
= 2 ounces
The percentage of ounces Joshua has left of his flavored water will then be:
= 2/32 × 100
= 1/16 × 100
= 6.25%
