First you have to do 440 / 20, which is 22 cents per bottle
Next you have to do 480 / 24, which is 20 cents per bottle
20 < 22, so the 24 ounces of shampoo is the correct answer.
Answer:
15i^2
Step-by-step explanation:
a negative times a positive is a negative and a negative times a negative is positive
-5×-3=15 and i×i=i^2
Answer: 42
Step-by-step explanation:
Let A represents the number of freshmen participated in sports and B represents the number of freshmen participated in clubs.
Then , we have given that
![n(A)=55\\\\n(B)=68\\\\n(A\cup B)=110](https://tex.z-dn.net/?f=n%28A%29%3D55%5C%5C%5C%5Cn%28B%29%3D68%5C%5C%5C%5Cn%28A%5Ccup%20B%29%3D110)
Using formula
![n(A\cup B)=n(A)+n(B)-n(A\cap B)](https://tex.z-dn.net/?f=n%28A%5Ccup%20B%29%3Dn%28A%29%2Bn%28B%29-n%28A%5Ccap%20B%29)
We have,
![110=55+68-n(A\cap B)\\\\\Rightarrow\ n(A\cap B)=123-110=13](https://tex.z-dn.net/?f=110%3D55%2B68-n%28A%5Ccap%20B%29%5C%5C%5C%5C%5CRightarrow%5C%20n%28A%5Ccap%20B%29%3D123-110%3D13)
Now, the number of students are involved in just sports is given by :-
![n(A)-n(A\cap B)=55-13=42](https://tex.z-dn.net/?f=n%28A%29-n%28A%5Ccap%20B%29%3D55-13%3D42)
Hence, 42 students are involved in just sports.

Step-by-step explanation:
(Given)
(Given)
- Perpendicular dropped from the center of the circle to the chord bisects the chord.
- Let the
be r ft.
- Radius of the circle, perpendicular to the chord and half of chord forms a right triangle where r represents the hypotenuse. Thus, by Pythagoras Theorem:
