Can someone help me with the first 3 as it is my first time doing it ? <br> I need help
Fed [463]

You problem is you don't have any problem. You have a bunch of formulas for the perimeter and area of some shapes.

As for using the formulas, usually you're given all but one of the variables and you can solve for the remaining one.

Notice how the triangle result doesn't have area as a function of a, b and c. That's called Heron's formula and is usually not taught to secondary school students. I don't like to teach it either because Archimedes' Theorem is so much better:

The sides a,b,c and area S of a triangle satisfy

16S^2 = (a+b+c)(-a+b+c)(a-b+c)(a+b-c) = 4a^2b^2-(c^2-a^2-b^2)^2 = (a^2+b^2+c^2)^2 - 2(a^4+b^4+c^4)

What is the probability of picking a card that is neither a club nor a 2 nor a 3?
I am Lyosha [343]

The amount of cards that isn't a club, 2, or 3 is 33 cards if we have a 52 card deck.

So our probability is 33/52

To get that to a percentage we need to change that to a decimal. To do that, we divide 33 by 52. If we do that we get 0.635 if we round to the nearest thousandth.

To change that to a percentage we multiply that by 100

0.635 times 100 equals 63.5

So the probability of picking a card that isn't a club, 2, nor 3 is 63.5%
