Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = \frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}

By substituting the given values in the question,

Total number of pages read by Davida = 28\frac{1}{2} = \frac{57}{2}

Time taken by Davida = 45 minutes

Since, 1 minute = \frac{1}{60} hours

Therefore, 45 minutes = \frac{45}{60}=\frac{3}{4} hours

Rate of reading = \frac{\frac{57}{2}}{\frac{3}{4} }

                          = \frac{57}{2}\times \frac{4}{3}

                          = 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.

Let's evaluate the ratio test:

\dfrac{a_n}{a_{n-1}}=\dfrac{3^{n+1}}{3n+1}\cdot\dfrac{3(n-1)+1}{3^n}=\dfrac{3\cdot3^n}{3n+1}\cdot\dfrac{3n-2}{3^n} = \dfrac{9n-6}{3n+1}

The limit as n \to\infty of this quantity is 3, which is more than 1. So, the series diverges.

Answer:

24.997 cm

Step-by-step explanation:

Find the diameter:

7(2) = 14 cm

Find the circumference:

C = \pi d

C = \pi (14)

C = 43.988

Divide the circumference by 4:

43.988/4 = 10.997

(This is the length of the curved side)

Add length to the other 2 sides:

7 + 7 + 10.997 = 24.997
