Answer:
C
Step-by-step explanation:
(a)
2 : 4 ( divide both values by 2)
= 1 : 2
3 : 6 ( divide both values by 3 )
= 1 : 2
Thus 2 : 4 = 3 : 6
(b)
3 : 9 ( divide both values by 3 )
= 1 : 3
Thus 1 : 3 = 3 : 9
(c)
4 : 6 ( divide both values by 2 )
= 2 : 3 ≠ 3 : 2
(d)
10 : 2 ( divide both values by 2 )
= 5 : 1
Thus 5 : 1 = 10 : 2
We are given that 8 oz of milk requires 15 oz of flour.
To know the amount of flour needed for 15 oz of milk, we will simply use cross multiplication as follows:
amount of flour needed = (15*15) / (8) = 28.125 oz
I've actually just learned this. We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. And using my calculator the square root of x^2 is just x. And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18.
Answer:
When the two values are different
Step-by-step explanation:
Like in an inequality equation.
For example:
The answer would be anything greate than or equal to 30, but you would need to find x. The number line would be very useful
Hope this helps
