Answer:
1/16
Step-by-step explanation:
Demont made one fourth (
) pound of rock candy
He separates the candy into four sacks equally.
This is done by dividing the total fraction of candy of a pound of candy made by the number of sacks
The fraction of a pound of candy that will be in each sack therefore is:
Therefore, One-Sixteenth of a pound of candy will be in each of the sack.
Answer:
7 feet is the length of the blade of the windmill.
Step-by-step explanation:
We have the equation
h = 7 sin(pi/21t) + 28 ------ eq1
At time 't' = 0, the end of the blade is pointing to the right parallel to the ground meaning it is at the same height as the other end. (Ф = 0°)
So, by calculating the maximum height of this end at Ф = 90°. we can calculate the length of the blade.
Now, we know that a general model equation of a circular simple harmonic motion is represented as : y = A sinωt + k ----- eq2
Where A is the amplitude that is, maximum displacement from mean to maximum position.
ω is the angular frequency.
Comparing eq1 and eq2:
A = 7
so the difference in blades end height at Ф = 0° and Ф = 90° is 7 feet.
Hence, the length of the blade is 7 feet.
5u > 64 - 14
5u > 50
u > 10
