Answer:
$1.27
Step-by-step explanation:
The cost of a unit item can be found by dividing the total amount paid by the total quantity given. In this case, the total quantitu is given as 3.05 pounds and the price is also given.
Since 3.05 pounds cost a total of $3.87 then the cost per pound would be given by dividing the amount paid by the pounds given
$3.87÷3.05=$1.2688524590163 per pound
Rounded off, then 1 pound is approximately $1.27
Answer:
The volume of the sphere is ![V=288\pi\ m^3](https://tex.z-dn.net/?f=V%3D288%5Cpi%5C%20m%5E3)
Step-by-step explanation:
<u><em>The question in English is</em></u>
Calculate the volume in m^3 of the sphere in which the area of one of its maximum circles is 36pi m^2
we know that
The radius of the maximum circle in the sphere is equal to the radius of the sphere
Step 1
Find the radius of the maximum circle
The area of the circle is
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
![A=36\pi\ m^2](https://tex.z-dn.net/?f=A%3D36%5Cpi%5C%20m%5E2)
substitute and solve for r
![36\pi=\pi r^{2}](https://tex.z-dn.net/?f=36%5Cpi%3D%5Cpi%20r%5E%7B2%7D)
Simplify
![36=r^{2}](https://tex.z-dn.net/?f=36%3Dr%5E%7B2%7D)
take the square root both sides
![r=6\ m](https://tex.z-dn.net/?f=r%3D6%5C%20m)
Step 2
Find the volume of the sphere
The volume of the sphere is
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
substitute the value of r
![V=\frac{4}{3}\pi (6)^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%286%29%5E%7B3%7D)
![V=288\pi\ m^3](https://tex.z-dn.net/?f=V%3D288%5Cpi%5C%20m%5E3)
Answer:
$63.45
Step-by-step explanation:
first, find 470% of 15. 470*15=$70.50. then, find 10% of it. 70.50 divided by 10 = $7.05. then subtract it from the new price to get the final price. 70.50 - 7.05 = $63.45
Answer:
20 and 25: 100
