Lbs : 4, 8, 12, 16
cost : 6, 12, ?, 24
12 lbs would cost u $ 18 because the apples cost (6/4) = 1.50 per lb
The relation is a function.
Step-by-step explanation:
As there is only one y-value for every x-value, this is a function

If a ratio of skiers and snumboarders is 1:2, and if there are 1250 snowboarders more than skiers, it means that is that there 2500 snowboarders and 1250 skiers.
How to check it? 2500 is 1250 more than 1250 and the ratio is still 1:2 (there are two times more snowboarders than skiers). Both conditions are fulfiled, so it's correct.
We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:
We need to solve for x, so let's isolate it:
So,
x = 10.2 units
