Try it.
8 =? 2*8 - 4
8 =? 16 - 4
8 =? 12
8 is not a solution of the original equation
Try 4
4 = 2*4 - 4
4 = 8 - 4
4 = 4 and yes 4 works.
4 is unique. No other solution will work.
Answer:
pi
Step-by-step explanation:
First find the circumference of a circle with radius 4
C = 2 * pi *r
C = 2*pi*4
C = 8pi
A circle has 360 degrees
Find the fraction of a circle that 45 degrees is
45/360 = 1/8
Multiply the fraction by the circumference
1/8 *8pi = pi
we know that
<u>A rate</u> is a ratio that compares quantities in different units. <u>A unit rate</u> is a rate where the second quantity is one unit
so
In this problem to find the unit rate
Divide $
by ![13\ ounces](https://tex.z-dn.net/?f=%2013%5C%20ounces%20)
![unit\ rate=\frac{5.99}{13}\frac{dollars}{ounce} \\ \\ unit\ rate=0.46\frac{dollars}{ounce}](https://tex.z-dn.net/?f=%20unit%5C%20rate%3D%5Cfrac%7B5.99%7D%7B13%7D%5Cfrac%7Bdollars%7D%7Bounce%7D%20%20%5C%5C%20%5C%5C%20unit%5C%20rate%3D0.46%5Cfrac%7Bdollars%7D%7Bounce%7D%20%20)
therefore
the answer is
the unit rate is equal to ![0.46\frac{dollars}{ounce}](https://tex.z-dn.net/?f=%200.46%5Cfrac%7Bdollars%7D%7Bounce%7D%20)
1 5/8 as a decimal is equal to 1.625 :)
Answer:
i believe the answer is 44
