The length of the marker is 130 millimeters (130mm).
Given:
A marker length is 0.13 m
Convert this length to millimeters!
or we can write as follow, let's say the length in mm is x
in the above calculation we can cancel the meter (m) unit because it is both on the top and bottom.
The most common metric unit of length use in Standar International kilometer (km), meter (m), centimeters (cm) and millimeter (mm). Explanation in converting them can be seen in the illustration below.

The formula of a circumference is:
r - radius
or
d - diameter
We have d = 12cm. Substitute:
One-fourth of the circumference:
Madame Curie had kg of radium at the beginning.
Madame Curie used ²/₅ kg for experiment
Radium left = 1¹/₄ kg
Question:
How much radium did she have at first?
The amount of radium that Madame Curie had at first :
= Radium for experiment+ the amount of radium left
we can do the additional if the denominator is the same, if not we need to find a common denominator, in this problem, the common denominator for 5 and 4 is 20, so the equation would be:
we change the mixed fraction into an improper fraction
So, at first, Madame Curie had 1 of radium

Answer: She invested $34100 at 10% and $68200 at 6%.
Steps:
Let x1 be the amount invested at 6%, x2 the amount at 10%
After one year the simple interest is amount * (interest rate).
The total interest after one year:
7502 = x1 * 0.06 + x2 * 0.10
and we know that x1 = 2*x2
7502 = 2* x2 * 0.06 + x2 * 0.10 = 0.22 * x2
x2 = 34100
x1 = 2*34100=68200
