Answer:
C. 18:30
Step-by-step explanation:
Divide the y values (games played) by the x values (games won) to find your ratio. The ratio across each of these pairs is 1.666667...
Using the ratio provided, 18:30, divide 30 by 18.
30/18 = 1.666667...
It's a match!
Therefore, the answer is C. 18:30
Answer:
Correct
Step-by-step explanation:
When you type 1/3 into a calculator it should give you something along the lines of .333333334. If you continue to round, eventually you will get 1.
Answer:
50% of 1/3: 1/2 x 1/3 = 1/6
75% of 1/2: 3/4 x 1/2 = 3/8
Step-by-step explanation:
50% = 1/2
50% of 1/3: 1/2 x 1/3 = 1/6
75% of 1/2: 3/4 x 1/2 = 3/8
I'm pretty sure it's 1/10 because it is one out of ten instead of one out of 12 ya feel
Direct variation is y=kx where k is a constant
the fiest way to see if it is direct or not, is if x increases, then y increases as well,
then we see if y=kx is valid, basically if we have a constant of variation
the first one x increase and y increase
see if same constant
y=kx
-4.5=-3k
1.5=k
so
see next one
-1 and 3
-3=-1(k)
-3=-1(1.5)
-3=-1.5
false
not it
2nd is increase and y decrease, so not direct variation
3rd is x is same but y increase so nope
4th is x increase and y increase, now test the constant
-7.5=-3k
2.5=k
-1 and -2.5
-2.5=-1k
-2.5=-1(2.5)
-2.5=-2.5
true
answer is last option
