The answer is A.
I'm too tired to explain. yadayadayada
Direct variation is y = kx
Inverse variation is y = k/y
if z varies directly with x, then the equation would be z = kx
if z varies inversely with y^2 then the equation would be z = k/y^2. Combining, these two, we have z = kx/y^2
We use the first set of values to find the constant k:
x = 2, y = 5, z = 8:
8 = 2x/25, k = 100. Now we use the second set of values to find z:
x = 4, y = 9, k = 100 and z is unknown:
z = (4X100)/9^2
z = 400/81--> this is your final final answer.

Let me help you,
For this question, you should know that 2 2/4 is equal to 10/4.
So we know that 10/4 is 10 times 1/4.
If Julie has 1/4-cup measuring cup, then she should use her cup 10 times to get 2 2/4 cups of raisins.
Have a good one!

Thanks
Step-by-step explanation:
Hey there!
Since 2 goes into 8, you would simplify. You would get 1 inch and 4 miles. Next, set up a ratio. The ratio is 1 inch: 4 miles. So for every inch on the map, there is 4 miles.
I hope this helps!
