Answer:
314 cm ^ 2
Step-by-step explanation:
First do, 3.14 x 20 ^ 2
3.14 x 20 ^ 2 = 1,256
Then do, 1,256/4
1,256/4 = 314
Why 4?
This part of the circle is 1/4 of the entire circle.
What does ^ mean?
It's just a way to say to the power of on a computer.
Hope this helps! :)
The keyword is "sum" which tells you x, y, and z are being added. One half of the sum means that the sum of the three numbers is going to be divided by 2.
x + y + z
------------

Let's call bicycles 'b' and unicycles 'u'
Note that bicycles have 2 tires, and unicycles have 1 tire.
We can make two equations:
b = u + 8
2b + 1u = 46
Solving the first equation for u, we get:
u = b - 8
Plug that equation into the second, and we get:
2b + (b - 8) = 46
Subtract 2b on both sides.
1(b - 8) = 46 - 2b
Basically, I used b and your question used n.
The correct answer is: D. 1(n - 8) = 46 - 2n.
Is it subtract 228? if so then 3-5 equals -2. -2-8 equals -10. -10-228 equals -238
Answer:
The simple interest is $300.
Step-by-step explanation:
<em>Find the Interest amount.</em>
I: Interest ?
P: Principle Amount $2500
R: Rate 6% = .06
T: Time Period (in years) 2 Years
<em>Convert into equation to find Simple Interest</em>
I = Prt
I = (2500)(.06)(2)
<em>Calculate</em>
I = 300
