Answer: 6
Step-by-step explanation:
The simple harmonic motion equation given in the question is
d=2sin(pi/3t)
The actual equation can be written as
d = A sin (bt )
where "A" is the amplitude and
Period is :
T=2π/(π/3)=6
So period is 6.
Hope I helped.
Answer:
684 Hours.
Step-by-step explanation:
If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.
3420/5 = 684.
(1 / 4) = .25
.25 * 100% = 25%
Uncle Bill ate 25%
Cousin Chris ate 15%
.3 * 100% = 30%
Cousin Timmy ate 30%
Little Dave ate 12%
You ate none.
Cousin Timmy ate the most, 18% of the turkey is left, and 82% of the turkey was eaten.
Defend my work in writing:
I converted my fractions and decimals to percents to find the different percents eaten for each person.
1 meter = 3.2808 feet
1 x 1 x 1 cubic meter = 3.2808 x 3.2808 x 3.2808 cubic feet
1 cubic meter = 35.3134 cubic feet
9 cubic meters = 35.3134 x 9 = 317.8 cubic feet.
