A spinner is separated into 4 equal pieces, as shown below:

kakasveta [241]

Getting black is 1/4 of the percentage, and spinning it 10 times gives us 10/40, because there are 40 possible colors to land on when u spin it 10 times. The last spin, is just like any other time you spin it. just because it's the last spin, doesn't make the black sector greater. So the answer is 1/4 or 25%.

If I have 85 dollars and I have to split it between 7 people, what is the most I can spend on each person?

pashok25 [27]

Each person will get 12 dollars

Step-by-step explanation:

Given

Total amount = 85 dollars

Total people = 7

As it has to be divided among 7 people, the total amount will be divided by 7

So,

Each person will get:

$=\frac{85}{7}\\= 12.14$

Rounding off to nearest whole number

12 dollars each with 1 dollar remaining

Hence,

Each person will get 12 dollars
