Answer:
7/8 = 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8
7/8 = 1/8 + 6/8
7/8 = 4/8 + 3/8
7/8 = 5/8 + 2/8
Step-by-step explanation:

Answer:
In order to answer this you would need to use this equation: <em>A = πr² </em> (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is <em>A = πr² </em>
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for <em>A = πr² .</em>
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :<em>A = π10.35² </em>
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n
Answer:
The rock remains in the air for t = 3.832 s
Step-by-step explanation:
To easily solve this equation, we can graph the equation with a calculator and see the interval for which the rock remains in the air.
(There is a minor problem with the equation, the last term should be 120 to model the 120 ft building)
h(t)= -16t^2 -30t + 120
Please see attached picture for the graph.
The time it takes for the ball to hit ground can be found by making
h(t) = -16t^2 -30t + 120 = 0
In the graph this point is equal to
t = 3.832 s
h(t) = 0
