The question involved the concept of combination because the order of the friends being picked are not considered. There are a total of 8 friends and 5 out of them are picked.
8C5 = 56
Therefore, there are 56 ways.

It's also 52 If I got it wrong I'm so sorry but I'm good at angles
Step-by-step explanation:
John Is Correct. We Know That 18 / 3 = 6, Then We Need To Multiply By 2 minutes. It Will Take Exactly 12 minutes.
Answer:
Step-by-step explanation:
The compounding formula for this is
where A(t) is the amount after all the compounding is done, P is the initial investment, r is the interest rate as a decimal, n is the number of times the interest compounds per year, and t is the time in years. For us, our n is 2, since the money compounds every 6 months, and 6 months goes into 1 year 2 times. Our formula then is:
which simplifies a bit to
which simplifies a bit more to

Raise 1.06 to the power of 18 and then multiply the 2 numbers together:
A(t) = 823(2.854339153) so
A(t) = 2349.12
Answer:
12
Step-by-step explanation:
The area of a triangle is calculated with the following formula:
(b: base, h: height (or legs))
We can use this formula to find the length of the other leg:
30 =
multiply both sides with 2 to get rid of fraction
60 = b*h one of the leg's length is given as 5 so
60 = 5*h divide both sides by 5
12 = h is the length of the missing leg.
