Step-by-step explanation:
124/4 = 31 pages per one fourth of the book
If your brother reads one fourth of the book then he reads 31 pages.
The circle is an illustration of intersecting chords.
The value of x is 4
<h3>How to determine the value of x?</h3>
The given parameters are:
- Chords: jk and lm
- Point of intersection = n
- jn = 3, nk = x, ln = 2, and nm = 6
This means that:
jn * nk = ln * nm
So, we have:
3 * x = 2 * 6
Divide both sides by 3
x = 2 * 2
Evaluate the product
x = 4
Hence, the value of x is 4

Step-by-step explanation:
<u>Vertical Throw</u>
It refers to a situation where an object is thrown verticaly upwards with some inicial speed v_o and let in free air (no friction) until it completes its movement up and finally returns to the very same point of lauch. The only acting force is gravity
The projectile formula is given as
where t is time in seconds, h is the height in feet and v is the speed in ft/sec
We are required to find the time t where h=120 ft, knowing
Rearranging
This is a second-degree equation which will be solved with the formula
Two solutions are obtained
Both solutions are possible because the ball actually is at 120 ft in its way up and then when going down
