what is the formula to calculate VAT percentage

Answers

Answer:

Take the gross amount of any sum (items you sell or buy) – that is, the total including any VAT – and divide it by 117.5, if the VAT rate is 17.5 per cent. (If the rate is different, add 100 to the VAT percentage rate and divide by that number.)

Answer:

divide by 117.5 if the rate different, add 100 to the percentage and divide by the number therefore multiply by 100 to get the total

The puppy needs to catch a train that is moving at 8km/hr. she is 100 meters away and running at 10km/hr. How far will the train have traveled before the puppy is able to jump on?

Answers

8000/3600 = 20/9, 10000/3600 = 25/9, 100/ (25/9-20/9) = 180 seconds 180 * 20/9 = 400 meters

The rabbit will jump on the train after the train moves 0.4km

The given parameters are:

[tex]d = 100m[/tex] -- distance between the puppy and the train

[tex]s_1 = 8km/hr[/tex] -- the speed of the train

[tex]s_2 = 10km/hr[/tex] --- the puppy's speed

Required

The distance where the puppy catch up with the train

First, we calculate the relative speed (rs) of the puppy to the train

[tex]rs =s_2 - s_1[/tex]

[tex]rs =10km/hr - 8km/hr[/tex]

[tex]rs =2km/hr[/tex]

Calculate the time to catch up with the train using:

[tex]Time = \frac{Distance}{Speed}[/tex]

[tex]t = \frac{100m}{2km/hr}[/tex]

Convert km to m

[tex]t = \frac{100m}{2*1000m/hr}[/tex]

[tex]t = \frac{100m}{2000m/hr}[/tex]

[tex]t = 0.05hr[/tex]

Calculate the distance to catch up with the train using:

[tex]Distance = Speed * Time[/tex]

[tex]d= s_2* t[/tex] --- speed of the train multiplied by the time

So, we have:

[tex]d = 8km/hr * 0.05hr[/tex]

[tex]d = 8km * 0.05[/tex]

[tex]d = 0.4km[/tex]

Christine said that y =√16x is a horizontal stretch by a factor of 1/16. Amanda said that it is a vertical stretch by a factor of 4. Who is correct and why?

Answers

Answer:

y = [tex]\sqrt{16}[/tex] x

that is equal to  y = 4x

[tex]\sqrt{16}[/tex] = 4

when graphing (x,y) the x is the horizontal value of the point (east west)

and the y in the vertical (north south) ....

if you have y = x it would be a 45 degree line that goes from the lower left to the upper right....

8.94 m
7.21 m
6.93 m
4.47 m

Answers

Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - [tex]a^2 + b^2 = c^2[/tex]. Use leg 1 as a, leg 2 as b, and the third side as c.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

[tex](4)^2 + (4*2)^2 = c^2[/tex]

Now, we use the Order of Operations to find [tex]c^2[/tex]...

[tex]4^2+8^2=c^2\\16+64=c^2\\80=c^2[/tex]

Now, we find the square root of [tex]c^2[/tex] to find c...

[tex]\sqrt{80} =8.94[/tex]

So, the length of the third side is 8.94 m.

Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan.
How old is Ishaan now?

Answers

Answer:

Ishaan is currently 15 years old.

Step-by-step explanation:

Let B represent Ben's current age and I represent Ishann's current age.

Ben is four times as old as Ishaan. In other words:

[tex]B=4I[/tex]

Six years ago, Ben was six times as old as Ishaan. In other words:

[tex]B-6=6(I-6)[/tex]

Solve for I. Substitute:

[tex](4I)-6=6(I-6)[/tex]

Distribute:

[tex]4I-6=6I-36[/tex]

Subtract 4I from both sides and add 36 to both sides:

[tex]2I=30[/tex]

And divide both sides by two. Hence:

[tex]I=15[/tex]

Ishaan is currently 15 years old.

Answer:

Age of Ishaan = 15 years

Step-by-step explanation:

Let Ishaan's age = x years

Age of Ben = 4 * x = 4x years

6Years ago:

Age of Ishaan = x - 6

Age of Ben = 4x - 6

6 years ago, Ben was 6 times as old as Ishaan

So, Age of Ben = 6 * Ishaan's age

     4x - 6 = 6 *(x-6)

4x - 6 = 6x - 36

Add 36 to both sides

4x - 6 + 36  = 6x  

4x + 30 = 6x

Subtract '4x' from both sides

30 = 6x - 4x  

30 = 2x

2x = 30

Divide both by 2 sides

x = 30/2

x = 15

Dan invests £18790 into his bank account. He receives 5.9% per year simple interest. How
much will Dan have after 2 years? Give your answer to the nearest penny where appropriate.

Answers

Answer: £21007.22

Step-by-step explanation:

First, find the interest amount using the formula SI = (P × R × T) / 100.

SI = interest amount P = principle amount = £18790R = interest rate(in percentage) = 5.9T = time(in years) = 2

SI = (P × R × T) / 100 = (18790 × 5.9 × 2)/100 = 221722/100 = £2217.22

The total amount = principle amount + interest amount

= £18790 + £2217.22 = £21007.22

Answers

Step-by-step explanation:

If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:

3x - 7 = 5(x - 5) and

3x - 7 = 5x - 25 and

18 = 2x so

x = 9. Now we sub that into the expression for AB (or DE since they're the same length):

3(9) - 7 = 20

Both AB and DE measure 20 units.

if the distance from one base to the other is 10 mm long and each triangle is 0.5 mm thick how many triangles would it take to fill up the prism

Answers

Answer:

2. 20

Step-by-step explanation:

2. The distance from one base of the prism to the other base of the prism, d = 10 mm

The thickness of each triangle to be used to fill the prism, t = 0.5 mm

The number of triangles needed, n, is therefore;

[tex]n = \dfrac{d}{t}[/tex]

Where;

d represents the distance between the bases of the prism, t, represents the thickness of each triangle, and n represents the number of triangles it would take to fill up the prism

Therefore;

[tex]n = \dfrac{10 \, mm}{0.5 \, mm} = 20[/tex]

The number of triangles it would take to fill up the prism, n = 20
