A computer costs £927 plus VAT, where VAT is charged 20% find the total cost of the computer

liubo4ka [24]

A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.

The total cost = original cost + VAT

Total Cost = 927 + 20% * 927

20% converts to decimal by moving the decimal 2 units up, so it is 0.2

= 927 + 0.2*927

Multiply to find value of tax

= 927 + 185.4

Add to find the total cost

Total cost = 1112.4 euros

I really don’t understand this and just need an explanation of how to do it.

$\bf ~\hspace{12em}\left( \cfrac{2n}{-3n\cdot -2n^2} \right)^4
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{2n}{-3n\cdot -2n^2}\implies \cfrac{1}{-3n}\cdot \cfrac{2n}{-2n^2}\implies \cfrac{1}{-3n}\cdot \cfrac{2n}{2n\cdot -n}\implies \cfrac{1}{-3n}\cdot \cfrac{2n}{2n}\cdot \cfrac{1}{-n}$

$\bf \cfrac{1}{-3n}\cdot \boxed{1}\cdot \cfrac{1}{-n}\implies \cfrac{1}{-3n\cdot -n}\implies \cfrac{1}{3n^2}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\left( \cfrac{2n}{-3n\cdot -2n^2} \right)^4\implies \left( \cfrac{1}{3n^2} \right)^4\implies \stackrel{\textit{distributing the exponent}}{\cfrac{1^4}{3^4n^{2\cdot 4}}}\implies \cfrac{1}{81n^8}$

What is the distance between (-2,2) and (2,-1) on coordinate plane

lawyer [7]

Answer:

$d=\sqrt(x2-x1)^{2} + (y2-y1)^{2}$

Step-by-step explanation:

1- Identify the x and the y

x1= -2

x2=2

y1= 2

y2= -1

2- solve the equation:

d= $\sqrt\$ (2-(-2)) $^{2}$ + ((-1)-2) $^{2}$

d= $\sqrt$ (4) $^{2}$ + (-3) $^{2}$

= $\sqrt$ 16 + 9

= $\sqrt$ 25

Determine whether the ordered pairs (1,4) and 6,

devlian [24]

Answer:

Not solutions.

Step-by-step explanation:

-5x+6y=-5

6y=-5+5x

6y=5x-5

y=5/6x-5/6

-5/6 is about -0.833

And the slope is 5/6.

So for every x there is 5/6y.

This means (1, 4) won't work cause it's too low.

Also 5/6*6=5. this is too low too.

So they aren't solutions.
