Answer:
Step-by-step explanation:
speed =65m/mins = 65/60 = 1.083m/s
Time taken to go down,
t = 4485/1.083
= 4141.37 s
Total time gotten = 12 hrs = 12*60*60
= 43200s
Amount of time left to conduct experiment
= 43200-4141.37
= 39058.63s
= 39058.63/3600
= 10.85 hrs
12 divided by 3 is 4
if 2 of each of these is stripped that means 8/12 are striped
1. The formula for calculate the area of a rectangle, is:
A=LxW
A is the area of the rectangle
L is the length of the rectangle.
W is the widht of the rectangle
2. You have that:
-The<span> rectangular Corn Hole area has a width of 5 feet and a length of 10 feet, so:
L1=10 feet
W1=5 feet
- When</span> a uniform amount is added to each side (x), the area is increased to 84 feet². Then, you have a different length (L2) and a different width (W2):
3. The new length is:<span>
L2=L1+x+x
L2=L1+2x
L2=10+2x
4. The new width is:
W2=W1+x+x
W2=W1+2x
W2=5+2x
5. The new area is:
A2=84 feet</span>²<span>
6. Then, you have:
A=LxW
84</span>=(10+2x)(<span>5+2x)
7. When you apply the distributive property, you obtain a quadratic equation:
4x</span>²+30x-34=0
<span>
8. You can solve with by applyin the quadratic formula:
x=(-b±√(b^2-4ac))/2a
a=4
b=30
c=-34
9. Then, the answer is:
x=1 feet

Part 1 : A=1/2 ap P= 2A/a = 1000/10 = 100 ft.
Part 2 : (100 ft.)($7.95/ft) = $795
I'm not sure for part 3.
