Shaniqua starts a bank account with a $120 deposit. By the end of 12 months, she hopes to have saved $900. She knows that she can save $30 per month from her paycheck, but can earn some extra money by tutoring on the weekend. How much extra per month does Shaniqua need to save in order to meet her goal? Select the equation that best represents this situation and solution.

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.

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

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.

Answer:

[tex]8(2x-1)[/tex]

WE used distributive property to generate this expression

Step-by-step explanation:

An equivalent expression for 16x − 8

To get equivalent expression we factor out GCF

[tex]16x--> 2,2,2,2,x[/tex]

[tex]8-->2,2,2[/tex]

Greatest common factor GCF is [tex]2 \cdot 2 \cdot 2 =8[/tex]

We take out GCF 8

16x − 8

[tex]8(2x-1)[/tex]

WE used distributive property to generate this expression

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]

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.

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'.
