Amazon is sold at rupees 99000 after 10% discount and 10% bat on the Marked price find the discount amount and vat amount
Answer:
Here,
SP with VAT = Rs. 99000
Discount = 10%
VAT = 10%
Discount Amount =?
VAT Amount = ?
We know,
SP = "100" /"100 + v% " × SP with VAT
= "100" /"100 + 10 " × 99000
= "100" /"110 " × 99000
= Rs. 90000 ∴ VAT Amount = SP with VAT – SP
= Rs. 99000 – 90000
= Rs. 9000 Again, MP = "100" /"100 – d% " × SP
= "100" /"100 – 10 " × 90000
= "100" /"90" × 90000
= Rs. 100000
∴ Discount Amount = MP – SP
= Rs. 100000 – 90000
= Rs. 10000
Step-by-step explanation:
Here is the list of all formulas on MP, Discount, SP, and VAT.
1. Discount Amount = Discount % of MP
2. Discount % = (Discount Amount)/MP ×100%
3. SP = MP – Discount Amount
4. SP = (100 - d%)/(100 ) × MP
5. MP = 100/(100 - d% ) × SP
6. VAT amount = VAT percent of SP
7. VAT percent = (VAT Amount)/SP ×100%
8. SP with VAT = SP + VAT amount
9. SP with VAT = (100 + v%)/(100 ) × SP
10. SP = 100/(100 + v% ) × SP with VAT
11. MP = (100 × 100)/((100 - d%)(100 + v%)) × SP with VAT
12. SP with VAT = ((100 - d%)(100 + v%))/(100 × 100) × MP
The mean of 14 numbers is 49. Removing one of the numbers causes the mean to decrease to 43. What number was removed?
Answer:
126 was removed.
Step-by-step explanation:
The total before division took place was
Total = mean * 14
mean = 49
Total = 49 * 14
Total = 685
Now you subtract x from the total
685 - x
And divide by 13 [one number is missing]
(685 - x)/13
and the result = 43
(685 - x ) / 13 = 43 Multiply both sides by 13
685 - x = 43 * 13
685 - x = 559 Subtract 685 from both sides
- x = - 126 Multiply by - 1
x = 126

Rona mixes 2 pounds of meat with some chopped vegetables to make a mixture. She divides the mixture into 4 equal portions. Each portion weighs 3 pounds. Which equation and solution shows the total amount of chopped vegetables she used in the mixture?
Answer:
The equation is (2+x) / 4 = 3
Total amount of chopped vegetables = 10 pounds
Step-by-step explanation:
Meat=2 pounds
Vegetables=x
Mixture= 2+x
She divides the mixture into 4 equal portions
(2+x)/4
Each portion weighs 3 pounds
(2+x)/4=3
Solve the equation
(2+x)/4=3
Cross product
(2+x) = 4 × 3
2+x=12
x=12-2
=10
x=10 pounds
Total amount of chopped vegetables = 10 pounds
15 lwholes 5 over 8 % of a number is 555 find the number
Answer:
The number is 3,552
15⅝% of 3,552 is 555
Step-by-step explanation:
15⅝% of a number is 555.
To determine what number it is, let the number be x.
Thus,
15⅝%*x = 555
[tex] \frac{125}{8}*\frac{1}{100}*x = 555 [/tex]
[tex] \frac{125}{800}*x = 555 [/tex]
[tex] \frac{125*x}{800} = 555 [/tex]
Multiply both sides by 800
[tex] \frac{125*x}{800}*800 = 555*800 [/tex]
[tex] 125*x = 444,000 [/tex]
Divide both sides by 125
[tex] \frac{125*x}{125} = \frac{444,000}{125} [/tex]
[tex] x = 3,552 [/tex]
The number = 3,552
15⅝% of 3,552 is 555

55. (a) If alpha and beta are the roots of the equation xsquare+ px+q=0 and beta>alpha find the square of the
difference of the roots in terms of p and q.
Answer:
√(p²-4q)
Step-by-step explanation:
Using the Quadratic Formula, we can say that
x = ( -p ± √(p²-4(1)(q))) / 2(1) with the 1 representing the coefficient of x². Simplifying, we get
x = ( -p ± √(p²-4q)) / 2
The roots of the function are therefore at
x = ( -p + √(p²-4q)) / 2 and x = ( -p - √(p²-4q)) / 2. The difference of the roots is thus
( -p + √(p²-4q)) / 2 - ( ( -p - √(p²-4q)) / 2)
= 0 + 2 √(p²-4q)/2
= √(p²-4q)

Answer:
[tex]\boxed {\boxed {\sf y=3}}[/tex]
Step-by-step explanation:
We are asked to find y, a missing side in a triangle.
1. Special Triangle RulesThis triangle is special. There is a 30-degree angle and a right angle or 90 degree angle, the unlabeled angle is 60 degrees. This is a 30-60-90 triangle so the sides are always in a specific relationship.
The side across from the 30-degree angle is a, the hypotenuse is 2a, and the side across from the 60-degree angle is √3 a.
y is across from the 30 degree angle, so it is equal to a. However, we have to find a. We are given one side that measures 6. It is the hypotenuse because it is across from the right angle. Therefore, it is equal to 2a.
2a= 6a is being multiplied by 2. Divide both sides by 2 to solve for a.
2a/2= 6/2 a= 6/2 a=3y is across from the 30-degree angle, so it is equal to a or 3.
2. Trigonometric Functions
We can also solve using the 3 main trigonometric functions.
sinθ= opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ= opposite/adjacenty is opposite the 30-degree angle and 6 is the hypotenuse, and we will use sine.
[tex]sin \theta= \frac{opposite}{hypotenuse}[/tex]
[tex]sin (30)= \frac{y}{6}[/tex]
y is being divided by 6. The inverse operation of division is multiplication. Multiply both sides by 6 to solve for y.
[tex]6 * sin(30)= \frac{y}{6} *6[/tex]
[tex]6 * 0.5 = y[/tex]
[tex]3= y[/tex]
The missing side, y , is equal to 3.

Maggie drew lines of best fit for two scatter plots, as shown. Which statement best describes the placement of the lines Maggie drew?
Answer:
B. Only line B is a well-placed line of best fit.
Step-by-step explanation:
A good line of best fit is a line drawn to represent, as much as possible, all data points. As long as the data points are clustered along the line, and are not farther from each other, the line is a best fit for such data points.
Therefore, from the two lines drawn by Maggie, Line B seems to be the only well-placed line of best fit, as virtually all the data points are clustered along the line, compared to Line A. Line A only runs across 2 data points. The rest data points are scattered far apart from the line.
Therefore, the statement that best describes the placement of the line of best fit drawn by Maggie is: "B. Only line B is a well-placed line of best fit."
Answer:
Only line B
Step-by-step explanation:
Line A is too low on the graph to be best fit for the plot

At a tanning salon, customers are charged \$10 for their first visit in a calendar month and \$6 for each visit after that in the same calendar month. In the last calendar month, 100 customers visited the salon, of which 30 made a second visit, and 10 made a third visit. All other customers made only one visit. If those visits were the only source of revenue for the salon, what was the revenue for the last calendar month at the salon
Answer:
The salon would've made $1,240.
Step-by-step explanation:
Think of the customers as the numbers and the visits as variables. Then the equation would look something like this:
Revenue = 100(first visit) + 30(second visit) + 10(third visit)
And now, we just solve:
r = 100(10) + 30(6) + 10(6)
r = 1,000 + 180 + 60
r = $1,240

Answer:
(3/2, 0, 1)
Step-by-step explanation:
From 2x+y=3 we have => y=3-2x
From 2y-4z=-4 we have -4z=-2y-4 => z=1/2y+1 => z=1/2 (3-2x) +1 => z=5/2-x
Plug in y & z to find x
2x−y+3z=6 => 2x+(3-2x)+3(5/2-x)=6 => 2x+3-2x+15/2-3x=6 => 21/2-3x =6 => x=3/2
plug in x to find y
2x+y=3 => 2(1.5) + y =3 => y=0
plug in y to find z
2y -4z =-4 => 2(0)-4z=-4 => -4z=-4 => z=1
A number y satisfies y 24th power - 256 = 0. What equation does the number x =y to the 4th power satisfy?
We conclude that the equation x = y^4 satisfies x = 256.
What does the equation x = y^4 satisfy?
First, we know that:
y^4 - 256 = 0
With this equation, we can find the value of y, it will give:
y^4 = 256
Then:
y = 256^(1/4) = 4
Now if we have the equation x = y^4, we can write:
x = y^4 = 256
x = 256
We conclude that the equation x = y^4 satisfies x = 256.

Explanation:
The 3^0 in the denominator is equal to 1. Any nonzero number raised to an exponent of 0 is always 1. So this equation x^0 = 1 is true when x is nonzero.
This allows us to simplify to the equation 3^x = 1/81
Note how 81 = 3^4. Taking the reciprocal of 81 means the exponent goes from positive to negative. So 3^(-4) = 1/81. The rule is x^(-k) = 1/( x^k ). We could use logarithms to solve 3^x = 1/81.
