17 boys, 21 girls
ratio is : 17:21 or 17/21
Answer:
300 m/min
Step-by-step explanation:
Using the general formula of d = rt, where d = distance, r = rate and t = time, we can solve for the missing variable (r, or speed). Given Tara's distance of 1600 m and her total time of 5 minutes and 20 seconds, first convert her time into just minutes:
5 
5
1600 = r(16/3)
Multiply both sides by reciprocal of 16/3: 3/16(1600) = r(16/3)(3/16)
Solve for 'r': 300 meters per minute
Answer:
Step-by-step explanation:
Question 18:
arc SRQ = 360° - 98° - 115° = 147°
y = 147°/2 = 73.5°
arc SPQ = 98° + 115° = 213°
x = 213°/2 = 106.5°
Sorry, I don't know how to answer 19.
Answer:
<u>There would be 11 books in each stack, to have the same number.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Books in stack 1 = 15
Books in stack 2 = 9
Books in stack 3 = 9
2. If the books were rearranged so that the stack had the same number of books how many books would be even?
Total books = Books in stack 1 + Books in stack 2 + Books in stack 3
Total books = 15 + 9 + 9
Total books = 33
Total books/Number of stacks = Number of books per stack to be the same
33/3 = Number of books per stack to be the same
<u>Number of books per stack to be the same = 11</u>
1+3+5+7+103=119. I hope this is what you were asking for! :)
