Naoya read a book cover to cover in a single session, at a rate of 555555 pages per hour. After reading for 444 hours, he had 33
siniylev [52]

Answer:

<h3>The function formula for the number of pages left to read is given by P(t)=55(10-t).</h3>

Step-by-step explanation:

Given that "Naoya read a book at a rate of 55 pages per hour".

After reading book for 4 hours, he had 330 pages remaining to read.

In 4 hours, Naoya must read is given by

\frac{55}{1hr}\times 4hr ( by given)

=220

<h3>∴ In 4 hours, Naoya must read 220 pages</h3>

From the given there were 330 pages remaining to read at the time,

The total number of pages is given by

=220+330

=550

<h3>∴ The total number of pages is 550 </h3>

For each hour of reading, Naoya reads 55 pages, so the number of pages he finished reading by the "t"th hour is given by 55t

Let P(t) be the number of pages to read where P is a function of time t (measured in hours)

So the number of pages left to read is given by

P(t)=550-55t

P(t)=55(10-t)

<h3>∴ the function formula for the number of pages left to read is given by P(t)=55(10-t).</h3>

Last week Martha read two fifths of an adventure book and this week she has read
shutvik [7]

Answer: Check explanation.

Step-by-step explanation: If she has 140 pages left to read, and completed 2/5 of the book last week, and 1/4 of the book this week, then we have to divide the pages left to read (140) by the fraction of pages she read last week (2/5), and this week (1/4).

When you divide 140 by 2/5 by 1/4, you get 1400. Hope this helped!
