A 40-inch TV costs $320 at the
store. The store advertises 20%
off all items in the store. The
sales tax is 6%. What is the sale
price including tax?
Tell me how to do it !!!
Answer:
Solution given:
Marked price of 40 inch TV =$320
discount [d]=20%
tax=6%
selling price including tax =?
we have
discount amount=d% of MP
=[tex] \frac{20}{100} ×320[/tex]=$64
again
selling price =MP - discount amount
=$320-$64=$256
again
tax amount =tax % of selling price
=[tex] \frac{6}{100} ×256[/tex]=$15.36
Now
selling price including tax=tax amount+selling price=$15.36+$256=$271.36
the sale price including tax is$271.36.

could you help me? how do i relate y to x and whats the answer to the bottom question?
Each time x goes up by 5, y decreases by 4
We can say the slope is
slope = rise/run
slope = (change in y)/(change in x)
slope = (-4)/(5)
slope = -0.8
The y intercept is 62 because this is the starting y value. The y intercept always occurs when x = 0.
Because the slope is m = -0.8 and the y intercept is b = 62, we go from y = mx+b to y = -0.8x+62
Therefore, the equation is y = -0.8x+62
This is the same as saying y = (-4/5)x+62 since -4/5 = -0.8
-------------------------
Interpretation:
The slope of -0.8 means that the height drops or decreases by 0.8 thousand feet per minute. Recall that y is in thousands. The phrasing "0.8 thousand" is probably better suited to call this 800 since 0.8*1000 = 800.
So it's probably easier to say "the height drops by 800 feet per minute".
As mentioned earlier, the y intercept is the starting height. The table shows x = 0 pair up with y = 62. Therefore, the starting altitude is 62,000 feet. After this point is when the UAV starts its descent.
Put another way: The cruising altitude was 62,000 feet and afterward the aircraft started its descent.

There is a 25% chance that Dane will make a three-point shot during a basketball game. A random-number generator generated 10 sets of random numbers from 1 to 4. The number 3 represents Dane's making a three-point shot. Look at the table.
Answer:
the 25% chance is wrong, it is actually 20%
Step-by-step explanation:
Based on the table of trials shown in the picture, it seems that the 25% chance is wrong. In the table, there are 10 trials and each one has 5 numbers generated, meaning there are a total of 50 numbers generated. Out of these 50 numbers, only 10 are the number 3. Since 3 is the only number that represents a three-point shot, that would make it a 20% (10 / 50) chance that Dane makes a three-point shot in a basketball game.

Step-by-step explanation:
First, find the probability that you will pull a yellow marble. There are 9 yellow marbles and 22 total, so the probability is 9/22. Then, find the probability that you will pull a green marble. There are 7 green out of 22 so the probability is 7/22. To find the probability of both, multiply them.
9/22 * 7/22 is 63/484

What is the slope of the line that
passes through these two points?
(1, 2)
(2,8)
Remember, given two points.
(X1. yı) rise (y2-yı)
Slope =
(X2- y2) "run (x2-x1)
Simplify your answer completely.
Enter
Answer:
The value of the slope is 6
Step-by-step explanation:
To get the slope of the line, we are going to make use of the slope equation
Mathematically, we have this as;
m = (y2-y1)/(x2-x1)
where (x1,y1) = (1,2) and (x2,y2) = (2,8)
Substituting these values;
m = (8-2)/(2-1) = 6/1 = 6

What is the perimeter of the following figure?
Answer:
13.4 x 2 = 26.8
12.5
HYPOTENUSE:
10^2 + 12.5^2 = 256.25
Square root of 256.25 = around 16
which would equal 256
16 is your hypotenuse.
26.8 + 12.5 + 16 = 55.3 is your perimeter

The following cone has a height of 4 inches and a volume of 12π. What is the radius of the cone? Enter your answer as the correct value, rounded to the nearest tenth if necessary.
Answer:
R= 1.69
Step-by-step explanation:
For this, you just have to remember that the volume of a cone is 1/3hπr² (1/3 times pi times the radius squared). Our volume is 12π, so we plug in 12π into our formula, as well as our height of 4 inches, to solve for the radius, like so:
12π=(1/3)(4)πr²
Now we just do the rest of the math.
12π=(1/3)(4)πr²
12=(1/3)(4)r² (divide both sides by π)
3=1/3r² (divide both sides by 4)
9=r² (divide both sides by 1/3)
3=r (take the square root of both sides).
Therefore, the radius of the cone is 3.

please show work!
Answer:
Not sure, read steps.
Step-by-step explanation:
First do the ()
29 - 6 = 23
6 + 5 = 11
SUBTRACT THE INTEGERS:
23 - 11 = 12
So, 2 x 12 = 24.
After Luca took his dogs for a walk, he gave them 6 dog treats. When Luca's dad got home from work, he gave
the dogs t more treats. All together that day, Luca's dogs got 10 dog treats,
Write an equation to describe this situation.
How many dog treats did Luca's dad give the dogs?
Answer:
Step-by-step explanation:am
Luca gave them 6 treats.
His father gave them t (unknown) treats.
All together, they got 10 treats.
This would be the equation:
[tex]6+t=10[/tex]
To solve, subtract 6 from each side.
[tex]6-6+t=10-6\\t=4[/tex]
Therefore, Luca's father gave the dogs 4 treats.
On a unit circle, the terminal point of Theta is
(Sqrt2/2, sqrt2/2). What is theta
A.
Pi/6
B.
Pi/3
C.
Pi/4
D.
Pi/2
Answer:
C. [tex] \frac{\pi}{4} [/tex]
Step-by-step explanation:
[tex]terminal \: point \: of \: \theta = \bigg( \frac{ \sqrt{2} }{2}, \: \: \frac{ \sqrt{2} }{2} \bigg) \\ \\ \implies \: (x, \: \: y) = \bigg( \frac{ \sqrt{2} }{2} \: \: \frac{ \sqrt{2} }{2} \bigg) \\ \\ \implies \: x = \frac{ \sqrt{2} }{2}, \: \: y = \frac{ \sqrt{2} }{2} \\ \\ \because \tan \theta = \frac{y}{x} \\ \\ \therefore \tan \theta = \frac{ \frac{ \sqrt{2} }{2} }{ \frac{ \sqrt{2} }{2} } \\ \\\therefore \tan \theta =1 \\ \\ \implies \tan \theta =\tan \bigg( \frac{\pi}{4} \bigg) \\ \\ \implies \: \theta \: = \frac{\pi}{4} [/tex]
