Write the product using exponents -3/7×3/7×3/7<br>​
zlopas [31]

Answer:

-(\frac{3}{7})^3

Step-by-step explanation:

Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.

-1 * (\frac{3}{7})^3= -1 * \frac{3}{7} *  \frac{3}{7} * \frac{3}{7}

We then multiply by -1 to (3/7)^3 to get the exact answer.

-(\frac{3}{7})^3

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%.
