answer : am/b
Step-by-step explanation:
the rate of copying packets = a/b
each packet (a) contains *m* pages
total number of pages in all books together is =a×m
so the rate of copying of pages = a×m/b
Answer:
All except complementary angle.
Step-by-step explanation:
Complementary angles equal 90 degrees.
Answer: The mean is <em>14</em> and the median is <em>14.5</em>
Step-by-step explanation:
To find the mean, add up all of the numbers in the series and divide by the amount of numbers in the series. In this case, the answer comes out to 14.
For the median, you put the numbers in order of least to greatest, as they are listed in the question. You then cross out a number from the left, then a number from the right, one at a time until you are left with either one middle number, or in this case two middle numbers. In this case you are left with 13 and 16. You then find the average of the two middle numbers, which in this case is 14.5
Hope this helps!
Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
