A student was conducting a study to determine how many pages he would need for the book he is writing. So, he found that the following number of words fit on each type of the following papers using an 11 point font:
Paper Size
Average Number of Words
8.5 inches by 11 inches
800
5.5 inches by 6.5 inches
300
12 inches by 18 inches
1900
The student looks up the word count on his favorite book, if the book has pages that are 5.5 in. x
6.5 in. and 57,978 words how many pages is the book?
Tour

step-by-step explanation:

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
