Answer:
A mass weighing 16 pounds is attached to a spring whose spring constant is 25 lb/ft. What is the period of simple harmonic motion?
Step-by-step explanation:
Let the number of 30 pound boxes represented by =x
Let the number of 20 pound boxes be represented by =y
As given, there are 64 boxes so equation is:
or ..... (1)
Total weight is 1400 pounds so equation becomes
...............(2)
Plug in the value of in 2nd equation
and
Hence, the number of boxes for delivery that weigh 20 pounds is 52.

Answer:
44 degrees and 46 degrees.
Step-by-step explanation:
If one angle is x degrees then its complementary angle is 90 - x degrees.
x is 2 degrees less than (90 - x) degrees so:-
(90 - x) - x = 2
90 -2x = 2
2x = 88
x = 44
the other angle = 90 - 44 = 46 degrees.
