Answer:
1
Step-by-step explanation:
First, you would divide 65 by 2 and you would get 32.5. Then, You would subtract 32 from 40 to get 8. Finally you would subtract 8 by 1995 to get your answer for what year was john exactly half his fathers age and that year would be 1987. Your welcome :)

Step-by-step explanation:
The equation that does not assign one value to y is
and the points that do not represent a function is (c)
<h3>The equation that does not assign one value to y</h3>
To do this, we simply make y the subject of formula.
So, we have:
![\frac 5y = 7x + \frac{10}{2y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B10%7D%7B2y%7D)
Simplify
![\frac 5y = 7x + \frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B5%7D%7By%7D)
Subtract 5/y from both sides
![0 = 7x](https://tex.z-dn.net/?f=0%20%3D%207x)
Rewrite as:
![x = 0](https://tex.z-dn.net/?f=x%20%3D%200)
This means that the value of x is 0 irrespective of the value of y
Hence, the equation that does not assign one value to y is ![\frac 5y = 7x + \frac{10}{2y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B10%7D%7B2y%7D)
<h3>The points that do not represent a function</h3>
For a set of point to represent a function, the points must represent a one-to-one or many-to-one relationship.
From the list of options, option (3) represents a one-to-many relationship.
This is so because one x value has 3 y values
Hence, the points that do not represent a function is (c)

Answer:
9 inches.
Step-by-step explanation:
Fun question! The length of a space diagonal for a cube is ![\sqrt{3*sidelength^2}](https://tex.z-dn.net/?f=%5Csqrt%7B3%2Asidelength%5E2%7D)
Thus, the first cube has a side diagonal of ![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
The next cube would have a side diagonal of 3
The third cube would have a side diagonal of ![3\sqrt{3}](https://tex.z-dn.net/?f=3%5Csqrt%7B3%7D)
And the fourth cube would have a side diagonal of 9.
Since the fifth cube has a side length equal to the side diagonal of the fourth cube, it should be 9 inches.
