The answer is the second option: T<span>wo places left.
Therefore, the complete text is: "</span>To obtain the number of centimeters from a distance measured in meters, move the decimal point Two places left ".
<span>
The explanation is:
1 meter has 100 centimeters, then, if you have a distance of 45.55 centimeters and you want to know this value in meters, you need to divide it by 100 or, in others words, you need to </span>move the decimal point two places left:
<span>
=(45.55 centimeters)(1 meter/100 centimeters)
=(45.55x1)/100
=0.4555 meters

21x is 21x im glad that I can help you
Answer:
680.. that is if we are only doing 4 weeks = a month but yeah :)
Step-by-step explanation:
What's the problem about geometry? Which section?
The magnification is 0.54
Given,
The distance between object and concave lens, u = -21 cm
Focal length of the concave lens, f = -25 cm
Let m be the magnification.
m = v/u
Here v is the position of image.
We have to find v first.
By using lens equation we can determine v.
That is,
1/f = 1/v – 1/u
So,
- (1/25) = 1/v – (-1/21)
- (1/25) = 1/v + 1/21
1/v = - (1/25) – 1/21
1/v = (-25 – 21) / (21 x 25)
1/v = - (46/525)
Therefore v = - (525/46)
v = -11.41 cm
Now we have to find magnification, m.
m = v/u
= (-11.41) / (-21)
= 0.54
Here magnification is 0.54
