Answer:
1. 1035 words
2. 21.74 min
Step-by-step explanation:
1. 23 words per min × 45min = 1035 words
2. 500 words/ 23 words per min= 21.74 min
8x2=16, 16 over 3 is roughly 5.33. so 5 is roughly 2/3rds of 8. Use basic cross multiplication
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3
n^-6 * n^3 = n^-3
If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.
n^-3 = n^-3 / 1 = 1/n^3
when the factor moves to the other side of the fraction, the side of the exponent changes.
The answer is 31.832142857.
