Answer
Find out the ratio represented the number of yellow balls to red balls .
To proof
Let us assume that the number of yellow balls be x.
As given
There are 20 balls in a bag.
Ten of the balls are red, 4 are green, and the rest are yellow.
than the equation becomes
x + 10 + 4 = 20
x = 20 - 14
x = 6
therefore the number of yellow balls be 6 .
Now find out the ratio between the the number of yellow balls to red balls .
the number of yellow balls be 6 .
the number of red balls be 10 .
solving
Therefore the ratio of the the number of yellow balls to red balls is 3 :5 .
Option (d) is correct .
Hence proved

Answer:
f(x) = 3x2
Step-by-step explanation:
I think the given the scatter plot is missing and it is my attachment for your question.
My answer:
f(x) = 3x2, it is a parabolic pathway. a =3 (positive) so the line is going up.
The other options are straight lines so they are wrong.

Answer:
12
Step-by-step explanation:
Maybe you want the equivalence ...
1 : 4 = 3 : 12
(Multiply both reduced ratio numbers by 3.)
