Answer:
√2
Step-by-step explanation:
Solving the given expression step by step:
![\frac{\sqrt{36} }{\sqrt{18} } = \frac{6}{3\sqrt{2} }\ \ \ [\because \sqrt{36} = 6 \ and \ \sqrt{18} = 3\sqrt{2}] \\ = \frac{3 \times 2}{3\sqrt{2} } = \frac{ 2}{\sqrt{2} }= \sqrt{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B36%7D%20%7D%7B%5Csqrt%7B18%7D%20%7D%20%3D%20%5Cfrac%7B6%7D%7B3%5Csqrt%7B2%7D%20%7D%5C%20%5C%20%5C%20%5B%5Cbecause%20%5Csqrt%7B36%7D%20%3D%206%20%5C%20and%20%5C%20%5Csqrt%7B18%7D%20%3D%203%5Csqrt%7B2%7D%5D%20%5C%5C%20%3D%20%5Cfrac%7B3%20%5Ctimes%202%7D%7B3%5Csqrt%7B2%7D%20%7D%20%3D%20%5Cfrac%7B%202%7D%7B%5Csqrt%7B2%7D%20%7D%3D%20%5Csqrt%7B2%7D)
We rationalize denominator and change it into a simpler form as soon as possible.
Answer:
.643
Step-by-step explanation:
just put it in the calc and round
X-3y, x=3, y=-2
(3)-3(-2)
(3)+(3*2)
3+6=9
The answer is $6.85
Every day she puts in .33 cents.
So 6 days is $1.98
1.98+4.87=6.85

Answer:
New length is 3 3/20 ft.
Step-by-step explanation:
The total board is 2 5/8 feet long. And since 5/6 of a foot is trimmed off, that means each piece of wood is 5/6 feet.
We can now set up an equation like this ---> 5/6 ⋅ x = 2 5/8
Now we're going to simplify ---> 5/6 ⋅ x = 2 5/8
5/6 ⋅ x = 21/8
(multiply both sides by 6)
5x = 63/4
(divide both sides by 5)
x = 63/20
x= 3.15
So, the new length is 3.15 feet long, or 3 3/20 in mixed fraction.
