I don't know? I think 4 or 5, but its a guess. I don't know how to actually figure it out? I don't know if use a ratio or proportion?
The ratio: 5 : 3 : 2
5 + 3 + 2 = 10
5 / 10 = 0.5 = 50 % peanuts
3 / 10 = 0.3 = 30 % walnuts
2 / 10 = 0.2 = 20 % cashews
0.3 * 12 = 3.6
Answer c
Thank you!
It is C
0.3 * 12 = 3.6
idk ik this dont help but yeah idk
To figure out how many cups of walnuts are needed to make 12 cups of the party mix, you would use the given ratio.
The ratio states that the mixture should be made up of peanuts, walnuts, and cashews in a 5:3:2 ratio by volume.
To find the amount of walnuts needed, you need to determine the proportion of walnuts to the total mixture.
First, add up the total number of parts in the ratio: 5 + 3 + 2 = 10.
Next, calculate the fraction that represents the proportion of walnuts: 3/10.
Finally, multiply the fraction by the total amount of the mixture (12 cups) to find the number of cups of walnuts needed: (3/10) * 12 = 3.6 cups.
So, the answer is not exactly 4 or 5 cups, but it is between 3 and 4 cups. Therefore, the correct option is c) 3 and 4.
