Answer:
<h2>The price should be either $3 or $20.</h2>
Step-by-step explanation:
The relationship between the number of calculators sold, x and the price p is given by two equations. R reffers the revenue of the company.
- x = 2300 - 100p.
- R = xp or, 6000 = xp or,
.
Now, <u>putting the value of the second equation in first equation</u>, we get
.
The price is either $3 or $20.
To answer this question you will convert the mixed number into an improper fraction. To do this you have to understand that The two wholes in the mix number each equal 3/3. This would give you 6/3 for the two wholes. Add the 6/3 to the 2/3 that are there in the fraction, and you will have 8/3. the quotient(answer to a division problem) is 8/3 as a fraction.
The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
