When I divided 4/7, I got .5714285714 then I divided 13/20, and I got .65 so I would say 4/7 I believe.
When I divided 1/4, I got .25 then I divided 1/6, and I got .1666666667 so I would say 1/4 I believe.
When I divided 5/6, I got .8333333333 then I divided 2/3, and I got .6666666667 so I would say 5/6 I believe.
I definitely hope this helps you, I tried my best! XO
A is the correct answer
(to find diagonal of a square , you can get help from Pythagorean Theorem)

good luck
Answer:
Minimum surface area =
Step-by-step explanation:
We are given that
Width of container=x cm
Length of container=2x cm
Volume of container=
We have to find the minimum surface areas that this container will have.
Volume of container=



Surface area of container=
Because the container does not have lid
Surface area of container=

Differentiate w.r.t x


Substitute 





Again differentiate w.r.t x

Substitute x=3.4

Hence, function is minimum at x=3.4
Substitute x=3.4
Then, we get
Minimum surface area =
In order to find the angle θ, in <u>radians</u>, whose<u> tangent</u> is
you have to follow those steps
Step 1
Using a<u> calculator</u>
Find the angle θ

Remember that
the angle θ belong to the second quadrant
so
Angle θ=
Step 2
Convert degrees to <u>radians</u>
we know that


therefore
the answer is
the angle θ is
