Answer:
9 cm
Step-by-step explanation:
Total surface area of a cube =486 cm²
We know that the surface area of the cube
=6l²
Therefore,
6l ²
=486
l² =81
l =9 cm
We are given the formula
H=L²<span> / f*c
where
</span>H = <span>maximum focus range/hyperfocal distance
</span><span>L = focal length of the lens
f = setting on the camera to reduce or enlarge the aperture
c = diameter of the circle of least confusion
We are to express the equation with the focal length on the left side.
So,
H f c = L</span>²
L = √Hfc
Answer:
4.2
Step-by-step explanation:
Because 1/5 has to be converted into the 100 as the denominator and the number you are supposed to have for the numerator so it can be easier and 4 is the whole number so it doesnt need to be in the equation.
1/5
X
20= 20/100 so now all you have to do is make that a decimal since it hasnt got to 100 or past it and you have your answer
Blaaaa you die.
Honestly I have no idea
