What is a rational number and how do you know?
What is the equation to Pi in math?
By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference of a circle is equal to pi times the diameter (c = πd).

Answer:
For the first section, you write the algebraic expression or equation that goes with the statement.
For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.
For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.
For the third section, replace the c values for 3 and the d values for 5.
For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers
For the last section, combine like terms and explain each step.

State the domain of f•g. Then find f•g, including any additional restrictions necessary on the domain of the composition
Answer:
Answer is option A
Step-by-step explanation:
The required function [f o g(x)] is -7/√(x + 3).
The domain of the function [f o g(x)] > - 3.
What is a function?A function is the relation between two sets. The first one is called domain and the second one is called range.
Given, f(x) = - 7/x
g(x) = √(x + 3)
Therefore, f o g(x)
= f[g(x)]
= f[√(x + 3)]
= -7/√(x + 3)
Now, the domain of f o g(x) > - 3.

Rena's grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown. A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent. How much will Rena have in this account after 4 years? Enter the correct answer in the box.
Answer:
$3,955
Step-by-step explanation:
Given that:
Initial deposit = $3500
Simple rate of interest = $3.25%
Number of years = 4
Simple interest = (principal * rate * time)
Principal = Initial deposit = $3500
Interest = $3500 * 3.25% * 4
Simple Interest = $455
Amount that will be in account after 4 years :
$3500 + $455 =$3955

Write and solve an inequality that represents the number of ride tickets, she can purchase.
(5 points)
Step-by-step explanation:
30-7=23 dollars remained
let x be the tickets number
so 0.75*x=23
x=23/0.75
x=31 at least.
Find the error and explain what the correct step should be
Answer:
m = 12, the error was that the student did not divide both sides by -. so they got the incorrect answer
Step-by-step explanation:
okay, so you want to get m
because m is divided by 3, to counter it, you multiply both sides by three
-m/3 = -4
-m/3 times 3 =-4 times 3
because 1/3 times 3 =1, and -4 times 3 = -12, you get
-m = -12
then, divide both sides by - (because you want positive m)
and you get m = 12
the error was that the student did not divide by the negative, so in the end, their sign was wrong.

Angela lives 0.6 mile from the park. It takes her hour to walk her dog to the park. How quickly are Angela and her dog walking in miles per hour?
Answer:
0.6 miles an hour
Step-by-step explanation:
since it takes her 0.6 miles to walk an hour and an hour to walk 0.6 miles.
0.6 = 3/5
Answer: 0.1 miles per hour
Since an hour has 6 10-minute segments, divide by 6.
0.6 ÷ 6 = 0.1
Your answer should be 0.1 miles per hour.
So, Angela and her dog are walking at 0.1 miles per hour.
Hope this helps!
Which of the following expression are equivalent to -11/4?
Answer:
B
Step-by-step explanation:

Water is flowing from Tower #1 to Tower #2 in the diagram below at a rate of 20 gallons per minute. Initially, Tower #1 contained 1650 gallons and Tower #2 contained 570 gallons. (a) How many gallons does each tower contain after 5 minutes? Show your work. (b) Let m be the number of minutes it takes for the two towers to contain the same number of gallons. Set up and solve an equation for m. PLEASE HELP
Answer:
Tower 1=1550 gal after 5 min
Tower2=470 gal after 5 minutes
Step-by-step explanation:
Answer:
Step-by-step explanation:
After 5 minutes, the amount of water that has flowed is ...
(20 gal/min)(5 min) = 100 gal
That amount has flowed out of Tower #1, so it now has ...
1650 -100 = 1550 . . . gallons in Tower #1
That amount has flowed into Tower #2, so it now has ...
570 +100 = 670 . . . gallons in Tower #2

A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?
Answer:
[tex]\huge\boxed{\texttt{480 miles}}[/tex]
Step-by-step explanation:
We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.
We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form [tex]\frac{miles}{hours}[/tex] .
[tex]\frac{720}{6}[/tex]
We can now make another ratio where we use a variable for the miles flown in 4 hours.
[tex]\frac{x}{4}[/tex]
Since the ratios are equal, we can create an equation.
[tex]\frac{720}{6}=\frac{x}{4}[/tex]
To find the value of x, let's cross multiply.
[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]
So the plane flew 480 miles in 4 hours.
