Answer:

Step-by-step explanation:
The correct question is
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Let
x -----> the time in hours
y ----> the number of pages left to read
we know that
The linear equation in point-slope form is equal to

In this problem we have
----> is negative because the linear function is decreasing

substitute




Answer:
The checkbook balance is $178 .7.
Step-by-step explanation:
As given
Sherry had an ending balance $ 125.36, outstanding deposits of $153.53, and outstanding checks of $100.19.
Thus
Checkbook balance = Ending balance + Outstanding deposits - Outstanding checks
Putting the values in the above
Checkbook balance = $ 125.36 + $153.53 - $100.19
= $ 278.89 - $100.19
= $ 178.7
Therefore the checkbook balance is $178 .7.
Answer:
51*pi or 160.221
Step-by-step explanation:
total volume = volume of a cone + volume of a cylinder
total volume = 1/3* pi*r^2* height(of cone) + pi* r^2 *height(of cylinder)
total volume = 1/3 * pi * 3^2 * 5 + pi * 3^2 * 4
total volume = 51*pi = 160.221
Answer:

Step-by-step explanation:
Since, By the given diagram,
The side of the inner square = Distance between the points (0,b) and (a-b,0)


Thus the area of the inner square = (side)²


Now, the side of the outer square = Distance between the points (0,0) and (a,0),


Thus, the area of the outer square = (side)²

Hence, the ratio of the area of the inner square to the area of the outer square

199.
the z score for the 90th percentile is 1.28, so you can solve the equation

which gets you the 199
