Answer:
Mass of liquid: 20.421g
Density= 1.0109405940594 g/mL
Explanation:
Mass of liquid
To find mass of liquid you take the mass of beaker + liquid (171.223g) and subtract it from the Mass of beaker (beaker without the water). The difference is the answer.
171.223g - 150.802g = 20.421g
Density
To find density you use the formula Mass/Volume. Take the Volume given, and the mass of the liquid you just found.
20.421mL/20.421g = 1.0109405940594 g/mL
Answer:
3 2/3 ft to the right
Explanation:
The picture of the question in the attached figure N 1
To better understand the problem see that attached figure with letters N 2
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
In this problem
Triangle A.D.F is similar to Triangle B.D.E ----> by AA Similarity Theorem
so
we have
substitute
solve for E.D
E.D is the length of the shadow
so
The person should move to the right x feet
convert to mixed number
