First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
First, set up a ratio:
The first fraction is the percentage (30% and
are the same thing) and the second is the loan payment (which is equal to the 30 in the first fraction) over their annual income (
).
First you divide $15,680 by 30, then multiply that quantity by 100. The value calculated then replaces
in your second fraction:
Answer: 2/3 = b/ac = d/e
Step-by-step explanation:
This is all I got if I got it right. Is this one of your answers?
The sum evaluates to 144. See the linked question in the comments for details.
What is the Equation for 99÷n=33
You could get this right to solve the equation by the n means that there are a missing number to solve the equation. To solve this equation, the operation you need to use is division because it show's the divide sign. the answer is 99 ÷3=33. N means the missing number is 3.
