I have 7 hundreds blocks, 5 tens blocks, and 8 ones blocks. I use my blocks to model two 3-digit numbers. What could my two numbers be?
Molly lives in Denver, Colorado. Her house is approximately 5,220 feet above sea level. Parker lives in Bombay Beach, California. His house is approximately 175 feet below sea level. Determine the difference between the elevations.
since one is below and one is above, just add the two together for the total distance between them
5220 + 175 = 5,395 feet between them
How do you find square roots? Example: Square root of 441.
The basics ones, like 25 (5) are easy but is there a formula for higher numbers?
-_- please explain, not just answer the Example.
Final answer:
The square root is a value that produces a specified quantity when multiplied by itself. For perfect squares like 441, the square root is an integer like 21. For non-perfect squares or higher numbers, use a calculator or raise the number to the 0.5 power.
Explanation:
Finding Square Roots
Finding the square root of a number involves identifying a value that, when multiplied by itself, gives the original number. For perfect squares like 25, the square root is an integer (in this case, 5). However, for higher numbers, especially those that are not perfect squares, you may need to use a calculator or apply the long division method for finding square roots. Additionally, understanding the concept of exponents helps simplify square roots. For instance, raising a number to the power of 0.5 is the same as taking the square root:
x2 = √x
To find the square root of 441, recognize that it is a perfect square, as 21 multiplied by 21 results in 441. Therefore, √441 = 21. For more complex numbers, a calculator's square root function, or the y* button to raise the number to the 0.5 power can be used. If you're working with roots beyond square roots, such as fourth roots, you could raise the number to the power of 0.25 or take the square root twice sequentially.

Name the property the equation illustrates.
–2.1 • 1 = –2.1
Identity Property of Multiplication
Inverse Property of Multiplication
Multiplication Property of –1
Identity Property of Addition
Solution: The correct option is option first, i.e., [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.
Explanation:
The correct option is first option : Identity Property of Multiplication.
Reason for correct option:
According to the identity property of multiplication, the product of a number and the identity element is equal to that number. The identity element for multiplication is 1.
Let x be any real number, then by identity property of multiplication [tex]x\cdot1=x[/tex].
Therefore, [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.
Reason for incorrect option:
According to the inverse property of multiplication, the product of number and inverse is equal to 1. In the given equation the result is not 1.
In the given equation the number is multiplied by 1 instead of -1. So, multiplication property of -1 is not the correct answer.
In the given equation multiplication property is used and there is no need of any addition property.
Hence, only first option is correct and [tex]-2.1\cdot 1=-2.1[/tex] by the Identity Property of Multiplication.

Write an expression that represents "the product of 12 and n".
The expression 'the product of 12 and n' can be written as 12n in mathematics. The word 'product' refers to the result of multiplication, thus the phrase means 12 multiplied by n.
In mathematics, an expression that represents 'the product of 12 and n' would be written as 12n.
In this expression, 12 is a constant and n is a variable.
The expression is saying to multiply 12 by whatever value n has. For instance, if n is 2, the value of the expression 12n would be 24 because 12 times 2 equals 24.
The word 'product' in math usually refers to the result of multiplication.
Therefore, the phrase 'the product of 12 and n' means '12 multiplied by n'.

A restaurant buys eggs in cases of 15 dozen eggs per case. The owner of the restaurant specializes in omelettes. He ordered three cases of eggs per day just for omelettes if H only contains four eggs, how many hours can be made from three cases of eggs?
135 omelettes can be made from three cases of eggs.
To find out how many omelettes can be made from three cases of eggs, we first need to calculate the total number of eggs in three cases.
Each case contains 15 dozen eggs, and since a dozen is 12 eggs, one case contains [tex]\(15 \times 12 = 180\)[/tex] eggs.
So, three cases would contain [tex]\(3 \times 180 = 540\)[/tex] eggs.
Now, if each omelette requires four eggs, we can find out how many omelettes can be made:
[tex]\[ \text{Number of omelettes} = \frac{\text{Total number of eggs}}{\text{Number of eggs per omelette}} \][/tex]
[tex]\[ \text{Number of omelettes} = \frac{540}{4} \][/tex]
[tex]\[ \text{Number of omelettes} = 135 \][/tex]
In the formula C=prn, p stand for ____?
A. Percent
B. Price Per Item
C. Promotion
D. Period
Answer: p is price per item, the correct option is B
Step-by-step explanation:
Here we may have the comission equation, wich stands for how much a part (the store, the employe, etc) gets for every sale.
comission = price*number of sales*percent of comission
C = p*r*n
where p is the price, r is the rate of comission (a number smaller than one) and n is the number of items sold.
Then, we have that p = price per item.
