Answer:
Weighted average is the average of a set of numbers, each with different associated “weights” or values. To find a weighted average, multiply each number by its weight, then add the results.
Step-by-step explanation:
We set up a proportion: 63/?= 28/100
Cross multiply: 28*?= 63*100
⇒ ?= 63*100/28= 225
28% of 225 is 63.
Information given to us:
10 4/5 total cake batter
18 cupcakes
First, we need to find the improper fraction of 10 4/5, which is 54/5. Now we can divide 54/5 by 18. Answer: every cupcake will use 3/5 cup.
Answer:
10
Step-by-step explanation:
1. The area of triangle is = (A*h)/2, where h is the height grounded on side A.
