Answer: Tunnel tent.
Step-by-step explanation:
The tent which has the minimum area requires less nylon to manufacture,
Since, the area of Pup tent = Area of 3 square each having side 8 ft + Area of 2 equilateral triangle having side 8 ft
= ![3 \times ( 8^2 ) + 2\times \frac{64\sqrt{ 3} }{4}](https://tex.z-dn.net/?f=3%20%5Ctimes%20%28%208%5E2%20%29%20%2B%202%5Ctimes%20%5Cfrac%7B64%5Csqrt%7B%203%7D%20%7D%7B4%7D)
= ![192+ 2\times \frac{64\sqrt{ 3} }{4}](https://tex.z-dn.net/?f=192%2B%202%5Ctimes%20%5Cfrac%7B64%5Csqrt%7B%203%7D%20%7D%7B4%7D)
= ![192+ 32\sqrt{ 3}](https://tex.z-dn.net/?f=192%2B%2032%5Csqrt%7B%203%7D)
= ![247.425625842\approx 247.43\text { square ft}](https://tex.z-dn.net/?f=247.425625842%5Capprox%20247.43%5Ctext%20%7B%20square%20ft%7D)
Now, the area of tunnel tent = Area of square having side 8 ft + total Area of half cylinder having radius 4 ft and height 8 ft
= ![8^2 + \frac{1}{2} [ 2\pi\times 4(4+8)]](https://tex.z-dn.net/?f=8%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%5B%202%5Cpi%5Ctimes%204%284%2B8%29%5D)
= ![64 + \pi\times 48](https://tex.z-dn.net/?f=64%20%2B%20%5Cpi%5Ctimes%2048)
= ![64 + 3.14\times 48](https://tex.z-dn.net/?f=64%20%2B%203.14%5Ctimes%2048)
= ![214.72\text { square ft}](https://tex.z-dn.net/?f=214.72%5Ctext%20%7B%20square%20ft%7D)
Since, 214.72 < 247.43
Thus, Tunnel tent requires less nylon to manufacture.
Using: A^2+b^2=c^2
A&b= (√10)^2=10
10+10=c^2
20=c^2
(take the square root of 20)
c=2√5
Your answer is D
Answer:
Step-by-step explanation:
The first answer is that the sale price is 25% cheaper its a dumb question.
The second answer is the 2nd option because it states that sale prices are 30% of the original. For example if you had a $100 item it would cost you 30% of that original price. But if you went to the first store it would cost you $70 dollars because its 30% off of the original price.
