The expression (5+23) is correctly described as a simple addition, resulting in a sum of 28. It exemplifies the basic operation of adding two numbers together, an essential mathematical skill.
Explanation:The phrase that correctly describes the following expression (5+23) is simple addition. This expression simply requires adding the two numbers within the parentheses, leading to an answer of 28. Unlike complex expressions that involve multiple operations and rules such as the distributive property or the order of operations (parentheses, exponents, multiplication and division, and addition and subtraction), this expression only requires basic addition.
The concept of addition is fundamental in mathematics, allowing for the combining of two or more numbers to find their total. Such operations are building blocks for more complex arithmetic and algebraic tasks.
It's also important to note that the order in which numbers are added does not change the sum, a principle known as the commutative property of addition.
Tom went on a bike ride to the store 3 miles away if it took Time 1/2 hour to get there in 2/3 of an hour to get back what was his average rate of speed miles per hour for the entire trip
In order to achieve the times that he did in going to and from the store, Tom went at an average speed of 5.14 miles per hour.
The store was 3 miles away which means that the distance of the entire trip is:
= Distance going + Distance coming
= 3 + 3
= 6 miles in total
The time he took was:
= Time going + Time coming
= 1/2 hours + 2/3 hours
= 0.5 + 0.67
= 1.17 hours
His average speed for the entire journey is:
= Distance / Time
= 6 / 1.17
= 5.14 miles per hour
In conclusion, Tom's average speed was 5.14 miles per hour.

List three numbers that are divisible by 3, 4 and five
To find numbers divisible by 3, 4, and 5, we need to find common multiples of these three numbers. One example is 30, and other possible numbers include 60 and 90.
Explanation:When we need to find numbers that are divisible by 3, 4, and 5, we can look for numbers that are common multiples of these three numbers. In other words, we need to find numbers that can be divided evenly by 3, 4, and 5 without any remainder. Let's take a look at the first few numbers and see if they satisfy this condition.
15: 15 is divisible by 3 (15 ÷ 3 = 5), divisible by 5 (15 ÷ 5 = 3), but not divisible by 4 (15 ÷ 4 = 3 remainder 3), so it is not a solution.20: 20 is not divisible by 3 (20 ÷ 3 = 6 remainder 2), not divisible by 4 (20 ÷ 4 = 5 remainder 0), but divisible by 5 (20 ÷ 5 = 4), so it is not a solution.30: 30 is divisible by 3 (30 ÷ 3 = 10), divisible by 4 (30 ÷ 4 = 7 remainder 2), and divisible by 5 (30 ÷ 5 = 6), so it is a solution.From our analysis, we found that the number 30 is divisible by 3, 4, and 5. We can list two more numbers by finding common multiples of these three numbers.

How is mode different from the median?
Suppose you have developed a scale that indicates the brightness of sunlight each category in the table is five times brighter than the category above it for example a day that is dazzling is five times brighter than a day that is radian how many times brighter is a dazzling day then a dim day
Dim=2
Illuminated=3
Radiant=4
Dazzling=5
Answer:
Basicly all you do is Multiply Dazzling 4 times by 5, so 5*5*5*5 and your answer is 125.
EXAMPLE ;
IF it was 2 times brighter you would count the catagories. There are 4. So you would do 2*2*2*2 and you answer is 16.

1. If one letter is chosen at random from the word combed, what is the probability that the letter chosen will be a "d"?
2. The sides of number cube have the numbers 2,4,8,9,4, and 7. If the cube is thrown once, what is the probability of rolling a 7?
3. A bag contains 12 red marbles, 10 green marbles, 2 yellow marbles, 19 blue marbles, and 9 purple marbles. What is the probability of pulling out a green marble?
Answer:
Probability that the chosen letter is d is [tex]\frac{1}{6}[/tex]Probability of rolling a 7 is [tex]\frac{1}{6}[/tex]Probability of picking a green is [tex]\frac{5}{21}[/tex]Step-by-step explanation:
Probability of choosing d in the word "combed"Given:
Alphabet: d
Word: combed
First, we note down the length of the word "combed";
The length is 6 characters
The we check the number of occurrence of d in the word "combed"
Occurrence of d = 1
Probability is then calculated as;
Probability of choosing d = [tex]\frac{Number of Occurrence}{Total Observation}[/tex]
By Substitution; Probability = [tex]\frac{1}{6}[/tex]
Probability of rolling a 7 in a cube of side numbers 2,4,8,9,4, and 7Given:
Roll number = 7
Sample Space= {2,4,8,9,4, 7}
Sample Size, n(S) = 6
We check the number of occurrence of 7 in the sample space
Number of occurrence = 1
Probability is then calculated as;
Probability of rolling a 7 = [tex]\frac{Number of Occurrence}{Sample Size}[/tex]
By Substitution; Probability = [tex]\frac{1}{6}[/tex]
Probability of pulling out a green marbleGiven
Red = 12
Green = 10
Yellow = 2
Blue = 19
Purple = 9
Total = 12 + 10 + 2 + 19 + 9 = 42
Probability of picking a green marble is then calculated as;
Probability of choosing d = [tex]\frac{Number of Green}{Total}[/tex]
By Substitution; Probability = [tex]\frac{10}{42}[/tex]
Probability = [tex]\frac{5}{21}[/tex]

Which of the following would be equivalent to 11 to the 8th power over 11 to the 3rd power?
A)11 to the 7th power over 11 to the 7th power
B)11 ⋅ 114
C)11 to the 0 power over 11 to the 5th power
D)110
Option: B is the correct answer.
[tex]B)\ 11\cdot 11^4[/tex]
Step-by-step explanation:We are given a numerical expression as:
11 to the 8th power over 11 to the 3rd power.
i.e. mathematically it is given by:
[tex]\dfrac{11^8}{11^3}[/tex]
Now, we know that if the numerator and the denominator terms are power terms such that both the terms are of same base then the resultant is the same base and the exponent of the base is: exponent of numerator minus exponent of denominator.
i.e.
[tex]\dfrac{a^m}{a^n}=a^{m-n}[/tex]
Here we have:
[tex]a=11,\ m=8\ and\ n=3[/tex]
Hence, we get:
[tex]\dfrac{11^8}{11^3}=11^{8-3}[/tex]
i.e.
[tex]\dfrac{11^8}{11^3}=11^5[/tex]
Now, this could also be written as:
[tex]\dfrac{11^8}{11^3}=11\cdot 11^4[/tex]
( since,
[tex]a^m\cdot a^n=a^{m+n}\\\\i.e.\\\\11^1\cdot 11^4=11^{4+1}=11^5[/tex] )

the left and right page numbers of an open book are two consecutive integers whose sum is 329. Find these page numbers.
Follow below steps:
The student is seeking to find two consecutive integers whose sum is 329. This is a mathematics problem and involves understanding of even and odd numbers as well as basic algebra. Since the numbers are consecutive, we can represent them as n and n + 1. The sum of these numbers given in the problem is 329, so we have the equation n + (n + 1) = 329.
Solving this equation:
Combine like terms: 2n + 1 = 329
Subtract 1 from both sides: 2n = 328
Divide both sides by 2: n = 164
Thus, the two consecutive page numbers of the book are 164 and 165
