Annapurna suppliers sold construction materials at Rs. 497200 to Sagarmatha suppliers
making 10% profit and adding 13% VAT. Find the cost price of the Annapurna suppliers.
Sagarmatha suppliers spent Rs 10000 for transportation cost and made Rs. 30000 profit and
levied local tax Rs. 20000 and sold to constructor. Find the additional VAT applicable amount
and the final price with VAT​

Answers

Step-by-step explanation:

annapurna suppliers to sagarmatha suppliers ,

SP = (100+10)%of 497200

=110/100 * 497200

SP = RS. 546920

VAT 1 = 13% OF 546920

= RS. 71099.6

SAGARMATHA SUPPLIERS TO CONSTRUCTOR,

CP=RS.546920

TC=RS.10000

PROFIT =RS. 30000

LT =RS. 20000

SP = RS. 60000

VAT=13%

VAT 2 = 13% OF 60000

= RS. 7800

final price with VAT = 7800+ 546920+71099.6

=RS. 625819.6

Final cost is 36463.6 and VAT end profit is 3646.36.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given

Material cost = 497200

10% profit = [tex]\frac{10}{100}[/tex] × 497200

= 49720

13% VAT = [tex]\frac{13}{100}[/tex] × 49720

= 6463.6

Hence, Final cost  = 6463.6 + 10000 + 20000

= 36463.6

VAT end profit = [tex]\frac{10}{100}[/tex] × 36463.6

= 3646.36

Hence, Final cost is 36463.6 and VAT end profit is 3646.36.

Find the length of DE using the distance formula. d =

Answers

Answer:

d = 10units

Step-by-step explanation:

The question is incomplete. Find the complete question attached

The formula for calculating the distance between two points is expressed by the formula;

d = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinate points (-4, 2) and (4, -4)

d = √(4-(-4))²+(-4-2)²

d = √(4+4)²+(-6)²

d = √(8)²+(-6)²

d = √64+36

d = √100

d = 10

Hence the distance between the points DE is 10units

Step-by-step explanation:

The type of graph or function is called Cubic Function

The type of graph is represented by the equation of y = a(x-h)³+k

Thus our equation for the graph is

Please help very urgent! :)

Answers

Answer:

y = - 0.05x - 1.9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

y = 20x ← is in slope- intercept form

with slope m = 20

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{20}[/tex] = - 0.05 , thus

y = - 0.05x + b ← is the partial equation

To find b substitute (2, - 2) into the partial equation

- 2 = - 0.1 + b ⇒ b = - 2 + 0.1 = - 1.9

y = - 0.05x - 1.9 ← equation of perpendicular line

a)

A sequence is defined by the term-to-term rule such as

[tex]U_{n+1}=U^3_n+2[/tex]

Given that

[tex]U_0=-3[/tex]

Substituting n = 0 to determine u₁

[tex]U_{0+1}=U^3_0+2[/tex]

[tex]U_1=U^3_0+2[/tex]

substituting [tex]U_0=-3[/tex]

b)

[tex]U_{n+1}=U^3_n+2[/tex]

Substituting n = 1 to determine u₂

[tex]\:U_{1+1}=U^3_1+2[/tex]

substituting [tex]U_1=-25[/tex]

[tex]U_2=\left(-25\right)^3+2[/tex]

Megan ran 9/12 of a mile and skips a 12th of a mile around the track how far around the track did Megan go in total use the benchmarks fraction 1/2 1 and 0 to help you estimate each answer before you solve

Answers

Answer:

She went a total of 5/6 of a mile around the track

Step-by-step explanation:

Here, we want to calculate the distance around the track travelled

So the total distance covered will be;

9/12 + 1/12 = 10/12 = 5/6

Bill charges $12 per hour for a plumbing job. Write the equation that shows the relationship between the numbers of hours Bill work's,h, and the amount of money he makes, m?

Answers

Answer:

m = 12h

Step-by-step explanation:

Since Bill charges $12 per hour, it implies for every hour he charges $12. Therefore, the amount of money he makes, m, is dependent on the number of hours he works, h. The higher the number of hours, the more his money. And vice versa.

So that;

m = 12h

Thus if Bill works for 6 hours, his amount of money would be;

m = 12 (6)

   = 72

m = $72

Bill would make $72 after working for 6 hours.

The graph shows the amount of money left after buying video games. Find the slope of the line

Answers

Answer:

It’s -20

Step-by-step explanation:

The slope of the line is m = -20.

What is the slope?

The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.

Note that the graph passes through points (2,80) and (4,40).

The formula for the slope of a line passing through the points (x₁,y₁) and (x₂,y₂) is:

m = (y₂-y₁)/(x₂-x₁)

Substitute the points (x₁,y₁) = (2,80) and (x₂, y₂) = (4,40) into the above equation:

m = (40 - 80)/(4 - 2)

m = -40/2

m = -20

Hence, the slope of the line is m = -20.

Which polynomial function f(x) has a leading coefficient of 1, roots4, 2, and 9 with multiplicity 1, and root-5 with
multiplicity 3?

Answers

Answer:

[tex]x^6-88x^4-142x^3+1695x^2+2350x-9000[/tex]

Step-by-step explanation:

In order to solve this function, we must first start by writting the factors of the polynomial. We can do so by including the given zeros, and the leading coefficient. So we get:

[tex]f(x)=1(x-4)(x-2)(x-9)(x+5)^{3}[/tex]

and now we can expand this by multiplying the given parenthesis, so we get:

[tex]f(x)=(x^2-2x-4x+8)(x-9)(x^3+3(5)x^{2}+3(25)x+125)[/tex]

[tex]f(x)=(x^2-6x+8)(x-9)(x^3+15x^{2}+75x+125)[/tex]

[tex]f(x)=(x^3-9x^2-6x^2+54x+8x-72)(x^3+15x^{2}+75x+125)[/tex]

[tex]f(x)=(x^3-15x^2+62x-72)(x^3+15x^{2}+75x+125)[/tex]

[tex]f(x)=x^6+15x^5+75x^4+125x^3-15x^5-225x^4-1125x^3-1875x^2+62x^4+930x^3+4650x^2+7750x-72x^3-1080x^2-5400x-9000[/tex]

10. What fraction describes how much more of the trail Callie hiked than Jon hiked?

Answer:

9. 1/10

10. 3/10

Step-by-step explanation:

9. What fraction describes how much more of the trail Jon hiked than Andrea hiked?

This is calculated as the number of miles Jon hiked - The number of miles Andrea hiked

1/2 - 2/5

= The Lowest Common Denominator is 10

= [(5 × 1) - (2 × 2)] /10

= [5 - 4] /10

= 1/10

The fraction that describes how much more of the trail Jon hiked than Andrea hiked is 1/10

10. What fraction describes how much more of the trail Callie hiked than Jon hiked?

This is calculated as the number of miles Callie hiked - The number of miles Jon hiked

4/5 - 1/2

= The Lowest Common Denominator is 10

= [(4 × 2) - (1 × 5)] /10

= [8 - 5] /10

= 3/10

The fraction describes how much more of the trail Callie hiked than Jon hiked is 3/10
