Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
Answer:
<u>3 batches of biscuits.</u>
Step-by-step explanation:
For one batch of biscuits, Mito uses 1/4 cup of flour to coat the countertop and the rolling pin.He also uses 2 1/2 cups of flour for each batch of biscuits he bakes
When he uses 7 3/4 cups of flour
Let the number of batches = x
convert the given data to decimal:
2 1/2 = 2.5 and 1/4 = 0.25 and 7 3/4 = 7.75
So, the equation representing the problem is:
2.5 x + 0.25 = 7.75
Solve for x
2.5x = 7.75 - 0.25 = 7.5
x=7.5/2.5 = 75/25 = 3
<u>So, the number of batches of biscuits = 3 batches.</u>
