Answer:
Step-by-step explanation:
The ratio of adult to children is determined by number of adult / number of children.
We want to determine the three ratios that are equivalent to 2 adults 5 children. So we will divide each of the given number of adults and children.
1) 8 adults 20 children = 8/20 = 2/5
2) 5 adults 8 children = 5/8
3) 20 adults 50 children = 20/50 = 2/5
4) 4 adults 10 children = 4/10 = 2/5
So the three ratios that are equivalent to 2 adults 5 children are
8 adults 20 children,
20 adults 50 children and
4 adults 10 children

Answer:
A. I can't quite see the question, but I'm pretty sure it's A
Step-by-step explanation:
Sin(A) = 1/3
Sin^2(A) + Cos^2(A) = 1
(1/3)^2 + cos^2(A) = 1
1/9 + cos^2(A) = 1
cos^2(A) = 1 - 1/9
cos^2(A) = 8/9
cos(A) = √(8/9)
√8 = √(2 * 2 * 2) = 2√2
√9 = 3
cos(A) = 2√2/3
If a divides c,
then 'a' is a factor of 'c'.
Also,
If 'b' divides c,
then 'b' is also a factor of 'c'
therefore,
'a' and 'b' are factors of 'c'
Hence, a and b divides 'c'
so, c = a*b
and ab will also divide c.
Hence, proved.
