Answer:

Step-by-step explanation:

Use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-7 - 5)^2 + (-7 - 9)^2}\\d = \sqrt{(-12)^2 + (-16)^2}\\d = \sqrt{144 + 256}\\d = \sqrt{400} = 20$

Answer:

The area is $28\ m^{2}$

Step-by-step explanation:

I assume that the figure is a square

The area of a square is equal to

$A=b^{2}$

where

b is the length side of the square

In this problem we have

$b=2(\sqrt{7})=2\sqrt{7}\ m$

substitute in the formula

$A=(2\sqrt{7})^{2}$

$A=28\ m^{2}$

after allowing 20 percent discount on the marked price of a radio 15 percent vat is levied on it , if its price become rs 22080

Kamila [148]

Answer:

Step-by-step explanation:

Hello, let's say that the price was P, a real number.

After 20% discount it become P - 20% * P = P* (1-20%) = P * (1 - 0.2)

= P * 0.8

And then we take 15% for the VAT, the new price become P * 0.8 * ( 1 + 15%)

= P * 0.8 * 1.15

And this is equal to 22080, so

P * 0.8 * 1.15 = 22080

and the amount of the VAT is P *0.8 * 0.15

$=\dfrac{22080}{1.15}*0.15=2880$

Hope this helps.

Thank you.
