For part a:
Archimedes' principle states that the buoyancy force acting on an immersed object is equal to the weight of the fluid displaced. Because half of W displaces the water, the force must also equal half of W.
So the answer is c] (1/2) ×W.
For part b:
For an object to float entirely above water, the density of that object has to be greater or equal to the density of the water (1.00 g/cm³). So for half of it to lie below the waterline, it must be half as dense (0.5 g/cm³).
So the answer is e] 0.5 g/cm³.
Hope this helps!
Answer:

Step-by-step explanation:
Any polynomial will have degrees of variable in integers and the degrees would be always positive.
It is conventional to write standard forms of polynomials in the descending powers of x.
i.e. we write for cubic polynomial the term containing x cube, and for power 5 polynomial, the term containing power 4, next power 3, thus strictly in descending order.
The given polynomial is

This is a polynomial because all x have powers in positive integers.
But this is not in standard form as highest degree of 4 is not the first term
Let us rearrange according to powers of m
We get

as standard form
Answer: 
Step-by-step explanation:
Given the following system of equations:

In order to solve the System of equations, you can use the Substitution method. The steps are:
1. You can solve for "x" from the second equation:

2. Substitute the equation obtained into the first original equation:

3. Now you must solve for "y":

4. Substitute the value of "y" into the equation
and evaluate:

Then, the solution is:

Answer:
221g
Step-by-step explanation:
561g divided by 33cm is how much 1 cm of rope would be so then you multiply that amount by 13
The fraction that has a numerator of 44 is 1.5 i belive that or 3.7
