She can shake everyone's hand by 9/10 hands in 3 minutes.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Glurpina is a polymorph alien and can grow extra limbs.
She has 3 hands and can shake everyone's hand at the alien conference in 10 minutes.
She can shake everyone's hand by 3 hands in 10 minutes.
She can shake everyone's hand by 1 hands in 10 / 3 minutes.
She can shake everyone's hand by how many extra hands in 3 minutes.
= 3/ 10 x 3
= 9/10
Thus, She can shake everyone's hand by 9/10 hands in 3 minutes.

Hello!
As you can see, 22 is the opposite angle. We are looking for the adjacent angle. Let's just call it x. Using SOH CAH TOA, we see that the tangent is the opposite divided by the adjacent side. Let's use that.
tan54≈1.38
This gives us the equation below.
1.38=22/x
Let's solve this equation for x.
1.38x=22
x=22/1.38
x=15.94
Therefore, the length of the shadow is about 15.94 meters.
I hope this helps!
The answer is 1432 x 54 = 77,328
Step-by-step explanation:
for given cone:
h = 3 ft, r = 3 ft
Let l be the Slant height of cone.
![\therefore \: l = \sqrt{ {h}^{2} + {r}^{2} } \\ = \sqrt{ {3}^{2} + {3}^{2} } \\ = \sqrt{9 + 9} \\ = \sqrt{2 \times 9} \\ \therefore \: l= 3 \sqrt{2} \: ft \\ \\ total \: surface \: area \: of \: cone \\ = \pi \: r(l + r) \\ = 3.14 \times 3(3 \sqrt{2} + 3) \\ = 9.42 \times 3( \sqrt{2} + 1) \\ = 28.26 \times (1.414 + 1) \\ = 28.26 \times 2.414 \\ = 68.21964 \\ \approx \: 68.2 \: {ft}^{2}](https://tex.z-dn.net/?f=%20%5Ctherefore%20%5C%3A%20l%20%3D%20%20%5Csqrt%7B%20%7Bh%7D%5E%7B2%7D%20%20%2B%20%20%7Br%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%7B3%7D%5E%7B2%7D%20%2B%20%20%7B3%7D%5E%7B2%7D%20%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B9%20%2B%209%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B2%20%5Ctimes%209%7D%20%20%5C%5C%20%20%20%5Ctherefore%20%5C%3A%20l%3D%203%20%5Csqrt%7B2%7D%20%20%5C%3A%20ft%20%5C%5C%20%20%5C%5C%20total%20%5C%3A%20surface%20%5C%3A%20area%20%5C%3A%20of%20%5C%3A%20cone%20%5C%5C%20%20%3D%20%5Cpi%20%5C%3A%20r%28l%20%2B%20r%29%20%5C%5C%20%20%3D%203.14%20%5Ctimes%203%283%20%5Csqrt%7B2%7D%20%20%2B%203%29%20%5C%5C%20%20%3D%209.42%20%5Ctimes%203%28%20%5Csqrt%7B2%7D%20%20%2B%201%29%20%5C%5C%20%20%3D%2028.26%20%5Ctimes%20%281.414%20%2B%201%29%20%5C%5C%20%20%3D%2028.26%20%5Ctimes%202.414%20%5C%5C%20%20%3D%2068.21964%20%5C%5C%20%20%5Capprox%20%5C%3A%2068.2%20%5C%3A%20%20%7Bft%7D%5E%7B2%7D%20)
