Answer:

Nina's rate is 12.7059 miles per hour (answer rounded up to four decimal places).

Step-by-step explanation:

Nina can ride her bike 63,360 feet in 3400 sec

1 mile = 5,280 feet

How many miles = 63,360 feet ?

Its 63,360 feet ÷ 5,280 feet × 1 mile = 12 miles

Nina's rate is 12 miles per 3400 seconds

1 hour = 3600 seconds

So in 1 hour, Nina rides \frac{3600}{3400} × 12 miles = 12.7059 miles (rounded up to four decimal places)

Nina's rate is 12.7059 miles per hour (answer rounded up to four decimal places).

How do I solve question 13 and 14?
xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\

if counting the sequence from a_{0} then a_{4} is 17, but if

a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\

counting from a_{1}, then a_{4} is 13.

14.

a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28
