Answer:
6^ (-15) = x
Step-by-step explanation:
6^-8 = blank 6^7
6^-8 = x* 6^7
Divide each side by 6^7
6^-8 / 6^7 = x 6^7 / 6^7
6^-8 / 6^7 = x
Since the bases are the same, we can subtract the exponents
6^ ( -8-7) = x
6^ (-15) = x
Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
