Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.
The pole is 3 feet from the stake.
To find:
The length of the rope to the nearest tenth of a foot.
Solution:
First draw a diagram according to the given information as shown below.
We know that, in a right angled triangle,
In triangle ABC,
Therefore, the length of the rope is 5.2 foot.
Kinetic energy possessed by moving train is
.
And mass
.
The formula for kinetic energy is
.
Solve for velocity:
Now put in the data:
Answer:
50 pack
Step-by-step explanation:
Number of packs at Costco = 30
Cost of 30 packs at Costco = $10.82
Number of packs at the other place = 50
Cost of 50 packs = $17.25
Cost of one pack when 30 packs are bought
Cost of one pack when 50 packs are bought
It is better to buy the 50 pack.
Difference in the unit prices = .
Lets first divide the deck into shapes, in this case, we will have three.
The first shape, will be the rectangle that represents the lower portion of the deck. Its' dimensions are 12ft x 33ft. 396 Square ft.
Next lets do the upper rectangular section. It has the dimensions of (22ft-12ft)*24ft. 240 Square ft.
Third, we have the last remaining shape, the right triangle. Its' dimensions are 1/2(22ft - 12ft)*(33ft - 24ft). 45 Square ft.
Finally! We can now add the three areas together to get the full figure.
396 Square ft + 240 Square ft + 45 Square ft = 681 Square ft!
