3. Find any three rational numbers between 1/2 and 3/2
Answer:
[tex] \frac{2}{3} \\ \\ \frac{2}{2} \\ \\ \frac{4}{3} [/tex]
Step-by-step explanation:
I hope that is useful for you :)
Answer:
For example 1/1, 2/3 and 4/3
Step-by-step explanation:
There is a great way to generate rational numbers between other rational numbers using:
[tex]\textrm{If:~~~~~~} \frac{a}{b} < \frac{c}{d}\vspace{7pt}\\\textrm{Then:~} \frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}[/tex]
So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.
(1+3)/(2+2) = 1/1, so we got our first rational number.
Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2
(1+1)/(2+1) = 2/3
(1+3)/(1+2) = 4/3
We could also look for a number between 1/2 and 2/3 and find
(1+2)/(2+3) = 3/5
And so on, so forth :)

x= 30 y=25
x=16 y=21
x= 32 y= 26
Answer:
the last one
Step-by-step explanation:
32+26=58
32-26=6
Answer:
The first number is 32 and the second is 26
Step-by-step explanation:
Let the two numbers be represented by x and y
1) x + y = 58
2) x - y = 6
x = 6 + y, we'll use put this in the first equation.
x + y = 58
6 + y + y = 58
6 + 2y = 58
2y = 58 - 6
2y = 52
2. 2
y=26, now let's find x, again use the first equation
x + y = 58
x + 26 = 58
x = 58 - 26
x = 32

The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?
An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,
V ∝ h(r²)
Also, k is the constant of proportionality, therefore, the equation now can be written as,
V = k×h×r²
Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, there are 20 students in a drama club,
5 of them will leave in next year, and d students will join,
We are asked to construct an expression to represent the total number of students in the drama club next year.
So, the present number of students in the club = 20
After next year = 20-5 = 15
After the joining = 15+d
Hence the expression showing the number of students in the drama club the next year is 15+d.
