Answer:
19,600
Step-by-step explanation:
0-49=50 numbers
n=50
r=3
C(n,r)=n!/(r!(n-r)!)
=50!/(47!)(3!)
C(n,r)=C(50,3)
=50!/(3!(50−3)!)
= 19600
It’s C
You would use cos for this equation
Cos(45)= x/5
5 x cos(45
And when you put that in the calculator you will get that answer C
Answer: 1 pound per $2
Step-by-step explanation:
Imagine this problem as a ratio:
Pounds : Dollars
3 : 6
To simplify this ratio, we see that a common divisor(in fact the only common divisor) is 3.
3/3 : 6/3
1 : 2
Therefore, we get 1 pound per $2
