Answer:
C. 154 in
Step-by-step explanation:
The radius of any circle is 1/2d (d is the diameter). So, our radius here is
r = 1/2(14)
r = 7
The area of a circle is A = (pi)(r^2)
We can approximate pi=3.14 and plug in everything we know to solve
A = (pi)(r^2)
A = (3.14)(7^2)
A = (3.14)(49)
A = 153.86
We can round that to 154 and that's your answer
Answer: The concentration of the mixture is 0.5 p % .
Step-by-step explanation:
Given: 5 gallons of p% boric acid is mixed with 5 gallons of water.
Amount of boric acid = p% of 5 gallons
![=\dfrac{p}{100}\times5\text{ gallons}= 0.05p\text{ gallons}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7Bp%7D%7B100%7D%5Ctimes5%5Ctext%7B%20gallons%7D%3D%200.05p%5Ctext%7B%20gallons%7D)
Total solution : 5 +5 = 10 gallons
then, the concentration of the mixture = ![\dfrac{\text{Amount of boric acid in solution}}{\text{Total solution}}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BAmount%20of%20boric%20acid%20in%20solution%7D%7D%7B%5Ctext%7BTotal%20solution%7D%7D%5Ctimes100)
![=\dfrac{0.05p}{10}\times100\\\\=0.5p](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B0.05p%7D%7B10%7D%5Ctimes100%5C%5C%5C%5C%3D0.5p)
Hence, the concentration of the mixture is 0.5 p % .
Thank you kind sir
The purpose of life is to learn and pass on what you have learned. We all started out a cell. That cell then became two. All throughout time people have learned and passed
on their knowledge. There is no real purpose to life except to learn and then pass on. From birth to death we learn and pass it on and in years, later on, we will know more and more. Never stopping this cycle. Until we know too much and the world ends from the power and fighting of the powers of human exists.
