Answer:
10
Step-by-step explanation:
find the sum, 8/10 plus 9/100
The answer is 89/100
All we have to do is multiple 110 by 0.20 to get the answer.
If we multiple the two numbers, we get the number 22, so the James family should leave a $22 tip.
By the by, if we combine the two numbers, we get 132, meaning that the James family will spend $132 in total.
Answer:
2 Movements
Step-by-step explanation:
Let us name the tokens
B-For Black Tokens
W-For White Tokens
The initial arrangement is therefore given as:
B-B-B-B-W-W-W-W-W
Since we are allowed to flip three tiles in each turn
First movement: Flip two blacks and one white, we would have:
B-B-W-W-W-W-W-W-B
Second movement: Flip the three black tokens, this would give us:
W-W-W-W-W-W-W-W-W
Therefore, the least number of movements to have all tokens showing the same color is 2.
