Think Winnie.
The distance a wheel traveled can be determined by using the circumference. The circumference of the wheel is pi meters. (formula is pi * diameter)
So if there were 8000 rotations, then the bus traveled 8000pi meters.
-3/7 is obviously the least because it is a negative number.Then 2/5 because if you think about it if 2/5 is 2 of 5 equal pieces. 2/3 is 2 of 3 pieces.So if you think about a pizza if you cut the pizza into 3 pieces and ate 2 imagine how much you would have left and then think about cutting the pizza into 5 pieces and only eating 2 . Think about that. So the answer in the end is -3/7,2/5, and then 2/3. Hope I helped!
Answer:
well if its 2*5 then its 10 because you have to count by 5's two times and you'll get 10. I hope this helps. :3
Let x = number of 5 cent coins.
Then there are (x+2) 10 cent coins.
Let y = 20 cent coins.
Total coins: x+(x+2)+y = 30
2x+y=28
y = 28-2x (1)
Total value: 0.05x + 0.1(x+2) + 0.2y = 3.80
0.15x + 0.2y + 0.2 = 3.80
0.15x + 0.2y = 3.60 (2)
Substitute (1) into (2).
0.15x + 0.2(28-2x) = 3.60
-0.25x + 5.60 = 3.60
2.00 = 0.25x
8 = x
From (1), obtain y = 28 - 2(8) = 12
Answer: (x+2) = 8+2 = 10
Louise has 10 10-cent coins
Log b 18 = logb 2 * 3 * 3
When multiplying logs, they are added together so:
logb 2 * 3 * 3 = logb 2 + logb 3 + logb 3
Logb 2 is given as 0.4307 and logb 3 is 0.6826
Now we have 0.4307 + 0.6826 + 0.6826 = 1.7959
Logb 18 = 1.7959
