Answer:
third and the first one
Step-by-step explanation:
Answer:
b. 5:3
c. 20:12 or 20 cups of flour and 12 eggs
d. 10 cups of flour
e. 9 eggs
Step-by-step explanation:
b. take one point from each number line and simplify it (example 15:9) and simplify it so you get your ratio of (5:3)
c. our ratio for one batch of cookies is 5:3 so mulitply 4 on both sides to find 4 batches of cookies
d. look at your numberline that represents number of eggs, 6 aligns with the number 10 on the numberline that shows "flour in cups" making your answer 10 cups of flour.
e. same thing as the problem before look at your numberline that shows cups of flour (which in this problem its 15) and see where that aligns on the "number of eggs" numberline above.
I would say 50 because 50 is between 40 and 60 50 is half of 100 so that is why I would say 50
I'll just make a manual computation on how 1 member recruits his members until week 5. Then multiply the sum by 2.
old new
1: 1
2: 1 x 3 = 3 ⇒ 1 3 *only new members recruit 3 more
3: 3 x 3 = 9 ⇒ 4 9
4: 9 x 3 = 27⇒ 13 27
5: 27 x 3 = 81 ⇒ 40 81
40 + 81 = 121. Total number of members under 1 founding member.
121 x 2 founding members = 242 total number of members within 5 weeks.
