Answer:
0.0707 radians
Step-by-step explanation:
Given that:
The dimension of the rectangular box is:
length (l) = 20 inches
width (w) = 20 inches
height (h) = 2 inches
The length of the diagonal of the rectangular box is :
The length of the diagonal of the base of the rectangular box is:
If we take a critical look at a rectangular box; we will realize that the diagonal of the base is the adjacent side & diagonal of the box is the hypotenuse of a triangle formed by the rectangular box.
Therefore, the angle between them is :
to radians
Answer:
Step-by-step explanation:
A=pi*d*h
750=pi*d*50
d=750/pi*50
d=4.77479, r=2.38739
or 2.39
To start, determine the amount of time needed to finish the book. Do this by multiplying the amount read at 45 minutes by the total time to read the book (x) and setting it equal to the time read, 45 minutes. This gives you (2/5)x=45. Next, solve for x. (2/5)x=45, multiply both sides by 5, 2x=225, divide both sides by 2, x=225/2 minutes to read the whole book. Now, divide your new time, 70 minutes, by the total time to read a whole book. This gives you 70/(225/2), which you would multiply the top by the reciprocal of the bottom, giving you 70*(2/225), now, you multiply the numerators by each other and the denominators by eath other, getting (70*2)/(1*225)=140/225. Now, you simplify, first by dividing each by 5, 28/45, which is the most simplified it could be. This makes your answer 28/45 of the book read in 70 minutes.
