Step-by-step explanation:
well 1.35 so when you round if its 50 you would round up and if its any lower you round down.
Answer:
![4.9\%](https://tex.z-dn.net/?f=4.9%5C%25)
Step-by-step explanation:
we know that
To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area
Let
x ----> the area of the hole
y ----> the area of the playing game
so
![P=\frac{x}{y}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![y=16\ ft^2](https://tex.z-dn.net/?f=y%3D16%5C%20ft%5E2)
<em>Find the area of the hole</em>
The area of the circle (hole) is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
----> the radius is half the diameter
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![A=(3.14)(0.5)^{2}](https://tex.z-dn.net/?f=A%3D%283.14%29%280.5%29%5E%7B2%7D)
![A=0.785\ ft^2](https://tex.z-dn.net/?f=A%3D0.785%5C%20ft%5E2)
<em>Find the probability</em>
![P=\frac{x}{y}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![x=0.785\ ft^2](https://tex.z-dn.net/?f=x%3D0.785%5C%20ft%5E2)
![y=16\ ft^2](https://tex.z-dn.net/?f=y%3D16%5C%20ft%5E2)
substitute
![P=\frac{0.785}{16}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B0.785%7D%7B16%7D)
![P=0.0491](https://tex.z-dn.net/?f=P%3D0.0491)
Convert to percentage
![0.0491*100=4.91\%](https://tex.z-dn.net/?f=0.0491%2A100%3D4.91%5C%25)
Round to the nearest tenth
![4.9\%](https://tex.z-dn.net/?f=4.9%5C%25)
Answer:
2 * 2 * 2 * 2 * 2 * 2, 4 * 16, 8 * 8.
Step-by-step explanation:
To make this easier, let's find the values of all the answers.
2^6 = 64.
So now we compare the values.
6 * 6 * 6 * 6 * 6 * 6 = 46656.
2 * 2 * 2 * 2 * 2 * 2 = 64.
2 * 6 = 12.
4 * 16 = 64.
12 * 12 = 144.
8 * 8 = 64.
