How Long Is The Book?

550 pages.

Its 550 pages, because if you know that he reads 55 pages an hour, then you can multiply the number of pages her reads in an hour by 4 hours. That's 220. Then he will still need 330, just add them together and you will get 550.

How Long Did It Take Naoya to read the entire book?

10 hours.

You know it takes him 4 hours to read 220, and you also know there's 550 pages. And you also know, he can only read 55 pages an hour, so just divide 550 ÷ 55.

1. 550 pages left

55×4=220+330=550

2. 10 hours

330÷55=6+4=10

The equation line l is given by the equation y= 7/4x+3. line m goes through the point ( –1,4) and is perpendicular to line l whi

mr_godi [17]

We determine line m as follows:

*First, by theorem we have the following:

$m_1=-\frac{1}{m_2}$

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

$m_1=-\frac{1}{\frac{7}{4}}\Rightarrow m_1=-\frac{4}{7}$

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

$y-y_1=m_1(x-x_1)$

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:
