He has to cross them and see which is dominant and then there will be the possibility to combine both
Take the lengths as 2x and 3x.
As per the question,
2x + 3x = 45
5x = 45
So, x = 45/5 = 9
To find the length of 1st segment : 2x = 2 * 9 = 18
And the length of the 2nd segment: 3x = 3 * 9 = 27
Hope this helps! :)
Answer:
A balance and a graduated cylinder.
Explanation:
<u><em>Density</em></u> is the relationship between mass and volume of a substance, the formula is:
ρ
Where m is the substance mass, and v is the volume.
If a student wants to measure the density of seawater, he or she should use a Balance, to measure the mass of the sample. And then use a Graduated cylinder, is a volumetric instrument that allows to contain liquids and then measures the exact volume of the sample.
Once the student obtains the mass and the volume, he/she has to replace the data in the density formula and so obtain the density of seawater.
