Answer:
12
Step-by-step explanation:
you can pack one pack in 20 min
there are three 20 min in one hour
multiply three times the four hours and you get 12
We Know that in geometry the Cos/Sin = Cotangent. And the abbreviation for this is cotø
Answer:
Sugar = 0.8 lb
milk = 0.6 lb
Flour = 2.6 lb
Step-by-step explanation:
Firstly, we add the ratios = 3 + 4 + 13 = 20
For milk, we have 3/20 * 4 = 12/20 = 0.6 lb
For sugar l, we have 4/20 * 4 = 16/20 = 0.8 lb
For flour = 13/20 * 4 = 52/20 = 2.6
Answer:
It takes 1 second for the tape to reach the ground.
Equation to use:
As explain above, the initial position s 16 ft, there is no initial velocity, so , and the acceleration of gravity is 32 ft/s^2, and should be considered negative [as pointing down in the y-direction], so the equation simplifies to:
In order to find the tima it takes it to hit the ground, we simple solve the equation for t when y(t) = 0 (the tape has reached the ground (zero height in the y-direction):
We select the positive time (+1 second) which is what makes physical sense, since a negative value in time would mean time before the tape was dropped.
So the answer is: It takes 1 second for the tape to reach the ground.
The answer to this question would be D.
