What is the perimeter of ABC with vertices at A (-11,4) B(-7,8) and C (-4,4)

Alborosie

Answer:

Step-by-step explanation:

Using the distance formula,

$AB=\sqrt{(-11-(-7))^{2}+(4-8)^{2}}=\sqrt{16+16}=4\sqrt{2}\\AC=\sqrt{(-11-(-4))^{2}+(4-4)^{2}}=7\\BC=\sqrt{(-7-(-5))^{2}+(8-4)^{2}}=\sqrt{4+16}=2\sqrt{5}\\\\$

So the perimeter is $4\sqrt{2}+7+2\sqrt{5}$

Anmol got 60 marks out of 80 marks in mathematics what percent marks did he get

Kay [80]

Answer:

75%

Step-by-Step Explanation:

There are two ways to go about this.

1) We can simply put it as a fraction = 60/80.

Then since a fraction sign also means division, we divide 60 by 80 = 0.75

Then to change a decimal into a percentage, we multiply by 100% = 75%

So our answer is 75%

2) We can simply it after it is put into a fraction = 60/80 = 3/4

It should be common knowledge that 3/4 is 75% depending on what grade you are in.

But there you have it, whichever way you prefer, the answer is always 75%.
