Answer:
Chiara has 2 penny coins and 24 nickel coins
Step-by-step explanation:
Let
p ----> the number of penny coins
n ---> the number of nickel coins
Remember that
Chiara has 26 coins that equal 34 cents
so
isolate the variable x
----> equation A
34 cents=$0.34
Multiply by 100 both sides
isolate the variable x
-----> equation B
Create a table to guess
assume different values of n and determine the value of p in equation A and equation B
The solution is when the value of p in the equation A must be equal to the value of p in equation B
1) For n=1
equation A
equation B
2) For n=2
equation A
equation B
therefore
The solution is (2,24)

Answer:
The volume of the sphere is
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
we have
substitute and solve for r
Simplify
take the square root both sides
Step 2
Find the volume of the sphere
The volume of the sphere is
substitute the value of r
