Aisha is spending a week at her family's cottage and wants to read her favourite book, which is 400 pages long. A) If she reads one page every 36 seconds, how many hours will it take her to read her book? B) Suppose Aisha only reads from 10:15 a.M. To 2:10 p.M., and from 7:20 p.M. To 9:00 p.M. Each day, starting on Monday. On what day and at what time will she finish reading her book? C) Aisha decides to read a second book that is 350 pages in length, starting right after finishing her first book. If she continues to read at the same speed, then when will she finish her second book?
Answer:
A) 4 hours
B) 7:25 PM on the same Monday.
C) 12:10 PM on Tuesday.
Step-by-step explanation:
Given that:
Number of pages in the first book = 400
A) Time taken to read each page = 36 seconds
To find the number of hours taken to finish reading the book, we need to first find the number of seconds taken to finish reading the book.
Time taken by Aisha to finish reading 400 pages = 400 [tex]\times[/tex] 36 = 14400 seconds
3600 seconds = 1 hour
14400 seconds = [tex]\frac{1}{3600}\times 14400[/tex] hours = 4 hours
B) Reading timings of Aisha :
1st time = 10:15 AM to 2:10 PM i.e. a duration of 3 hours and 55 minutes
2nd time = 7:20 PM to 09:00 PM i.e. a duration of 1 hour and 40 minutes
4 hours are taken to read this book.
So, it will require 5 more minutes after the 1st reading time.
Therefore, Aisha will finish reading at 07:25 PM on same Monday.
C) Second book has 350 pages.
Time taken to read 350 pages = [tex]\frac{350\times 36}{3600}[/tex] = 3.5 hours
She starts reading at 07:25 PM on Monday.
Up to, 9 PM, a duration of 1 hour and 35 minutes will be utilized for reading the second book.
A total of 1 hour and 55 minutes more will be required.
Therefore, the second book reading will be finished at 12:10 PM on Tuesday.

Petra jogs 2 miles in 24 minutes. At this rate, how long would it take her to jog 12 miles?
Answer:
144 minutes or 2 hours and 24 minutes
Step-by-step explanation:
12 miles divided by 2 miles = 6
24 * 6 - 144
So the final answer is 144.
Answer: 144 minutes
Step-by-step explanation:
If she can run 2 miles in 24 minutes and she needs to run 12 miles you need to multiple 24 and 6 ( You get a six because 24 minutes is for TWO miles. So you need to split the 12 in half.)

Look at the angle. Which description is true?
It's less than 90°
It's equal to 90°
It's greater than 90°. HELP ASAP
Answer:
Less than 90 degrees
Step-by-step explanation:If it were equal to 90 degrees it could make a perfect square as the angle and if its more it would be open wide i guess im a bad explainer sorry
Hence , Option B is correct. It is less than 90 degrees.
What is an Angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
How To Solve:Observe the given figure. A perfect Right Angle is in the shape "L"(or opposite/mirror L also). One can measure or construct it using a protractor.
If the L seems to be bent inwards , then its an acute angle and if the L is bent outwards, then it is an obtuse angle.
From the given figure it can be concluded that the angle formed is an acute angle and hence its is less than 90 degrees.

A plane is going to fly 300 miles at a planned speed of 530 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time

300
T(W) =
530-W
I need help with the bottom part. What does t(110) mean I’m this situation etc.
Answer:
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
Step-by-step explanation:
Given
[tex]w = headwind[/tex]
[tex]T = time[/tex]
Model:
[tex]T(w) = \frac{300}{530 - W}[/tex] -- This was not properly presented in your question
Required
What does T(110) means
First, we calculate T(110):
Substitute 110 for w in [tex]T(w) = \frac{300}{530 - W}[/tex]
The expression becomes
[tex]T(110) = \frac{300}{530 - 110}[/tex]
[tex]T(110) = \frac{300}{420}[/tex]
[tex]T(110) = 0.714[/tex] -- approximated
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

Answer:
m = 2, c = -8.
Step-by-step explanation:
The general form of a straight line equation is
y = mx + c where m = the slope and c is the y-intercept.
We are given the line
y = 2x + 4
Comparing this with the general form we see that the slope of this line = 2 and the y-intercept C is 4.
Now the given line y = mx + c is parallel to y = 2x + 4 which means that their slopes are the same so we conclude that m = 2.
Now we need to find the value of c which is the y intercept of y = mx + c.
Consider the points A and B:
A is the point where the line y = 2x + 4 intersects the x axis so y = 0 at this point , So substituting in the equation:
0 = 2x + 4
-4 = 2x
x = -2.
So the point A is (-2, 0)
B is the point where y = 2x + c cuts the x axis so here y = 0:
0 = 2x + c
2x = -c
x = -c/2.
Now we are given that the 2 intercepts are 6 units apart, so:
-c/2 - (-2) = 6
-c/2 + 2 = 6
-c/2 = 4
-c = 8
c = -8.
