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.
Which number has the greatest value
1. Use both methods to find the distance between the points on the number line.
Method A: Count the number of units between the points.
Method B: Take the absolute value of the difference of the two numbers.
When taking the absolute value, show that the greater number or the lesser number can be the subtrahend (the number subtracted).
To find the distance between two points on the number line, we can use two methods. The first is by counting the number of units between the two points, and the second is by taking the absolute value of the difference of the two points. Both methods lead to the same result.
Explanation:We will use two methods to find the distance between two points on a number line.
Method A: This involves simply counting the number of units between the two points. For example, if the points are 3 and 8 on the number line, you count the units between these points: 4, 5, 6, and 7. Thus, there are four units between the points 3 and 8.Method B: This method involves taking the absolute value of the difference of the two numbers. In the same example, to find the distance between 3 and 8, first subtract one from the other (e.g., 8 - 3 or 3 - 8). You get 5 or -5. Then take the absolute value of these numbers, which makes negative numbers positive, and therefore both 5 and -5 become 5. So the distance between the points 3 and 8 is 5.From both methods, we can see that the distance between the two points on the number line, whether you count the units or take the absolute value of their difference, is the same.

Jane has 38 marbles of the same shape and size in a box. The colors and amounts of the marbles are shown below:
•14 white marbles
•9 gray marbles
•15 blue marbles
Without looking in the box, Jane takes out a marble at random. She then replaces the marble and takes out another marble from the box. What is the probability that Jane takes out a gray marble in both draws?
9/38x8/37 =72/1406
9/38+8/37 =637/1406
9/38+9/38 =684/1444
9/38x9/38 =81/1444
Answer:
The correct option is D. 9/38x9/38 =81/1444
Step-by-step explanation:
Total number of marbles in the bag = 38
Number of white marbles in the bag = 14
Number of gray marbles in the bag = 9
Number of blue marbles in the bag = 15
We need to find the probability that Jane takes out a gray marble in both draws
[tex]\text{Probability that Jane draws gray marble in first draw = }\frac{9}{38}[/tex]
Given that : Then Jane replaces the marble for the second draw
[tex]\text{Probability that Jane draws gray marble in second draw = }\frac{9}{38}[/tex]
[tex]\text{Probability that Jane draws gray marble in both draws = }\frac{9}{38}\times \frac{9}{38}[/tex]
[tex]\text{Probability that Jane draws gray marble in both draws = }\frac{81}{1444}[/tex]
Therefore, The correct option is D. 9/38x9/38 =81/1444

Atticus wants to buy of a square yard of wrapping paper. The paper costs $2.40 per square yard. How much will Atticus spend on the wrapping paper?
a.$1.60
b.$4.80
c. $7.20
d. $9.20
Final answer:
Atticus will spend $4.80 on the wrapping paper.
Explanation:
To find out how much Atticus will spend on the wrapping paper, we need to multiply the cost per square yard by the number of square yards desired.
Given that Atticus wants to buy a square yard, we multiply by to get.
Therefore, Atticus will spend $4.80 on the wrapping paper, which corresponds to option b.

Given ABCDEF ≅ GHIJKL . What is the measure of ∠K ? Enter your answer in the box. m∠K = blank °
Hello! Let me help!
Answer: 114
Step-by-step explanation: So, I gave you an answer, but how is it right? If you see between ABCDEF and GHIJKL there is ≅. That means congruent, and or equal (identical.)
So, looking at ABCDEF, the fifth letter is E. Then look at the other one, the fifth one is K. Which, K is what we're trying to figure out. Well, if the angles are congruent all letters are equal to the other letters. So, Look for E on the left-hand shape. WOAH! What does it show over top of the letter?! Oh! It's 114. Which means.
The answer means E ≅ K. Which also means. E ≅ 114. and! 114≅K.

multiply using partial products . Record the products 56x 32
Final answer:
To multiply 56 by 32 using partial products, break down the numbers into their place values, multiply each component, and add the partial products to get the final product, which is 1792.
Explanation:
To multiply 56 by 32 using the method of partial products, you break down each number into its place value components and then multiply each component of the first number by each component of the second number before adding all the products together.
First, break down 56 into 50 and 6.
Second, break down 32 into 30 and 2.
Multiply each part of 56 (50 and 6) by each part of 32 (30 and 2) separately:
50 x 30 = 1500
50 x 2 = 100
6 x 30 = 180
6 x 2 = 12
Finally, add all these partial products together:
1500 + 100 + 180 + 12 = 1792
The product of 56 and 32 using partial products is 1792.

What is a fraction ?
A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.
The fraction given is [tex]5\frac{1}{6}[/tex] . This is a form of mixed fraction.
We know that the mixed fraction is written in form [tex]r\frac{x}{b}[/tex] and to change it in form a/b we need to multiply b with r , and then add it with x , which is equal to a , and then divide it by b.
i.e.,
Here , r = 5 , x = 1 and b = 6
So , b × r = 30 and when added with x = 1 , we get :
a = b × r + x = 31
dividing it by b we get :
a/b = 31/6
It is fraction in form a/b.
Therefore , the given mixed fraction [tex]5\frac{1}{6}[/tex] can be expressed in the form [tex]\frac{a}{b}[/tex] as equal to [tex]\frac{31}{6}[/tex].

the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of the water when the pipe has a diameter of 1.5 inches.
Answer:
The height of water is 7.3 inches, when diameter of pipe is 1.5 inches.
Step-by-step explanation:
We are given the following information in the question:
[tex]f(h) = 2d + 4.3[/tex]
where f(h) is a function for height of water and d is the diameter of pipe in inches.
We have to calculate height of water when d = 1.5 inches.
Putting d = 1.5 in the above equation, we get:
[tex]f(h) = (2\times 1.50)+ 4.3 = 7.3[/tex]
Hence, the height of water is 7.3 inches, when diameter of pipe is 1.5 inches.
The attached image shows the graph for the given equation.

is the product of 7 negative numbers and 8 positive numbers a positive number or a negative number
The product of 7 negative numbers and eight positive numbers will be harmful. This is because the result of multiplying an odd number of negative numbers is negative. The outcome remains negative when this negative number is multiplied by positive numbers.
Explanation:The result of multiplying even numbers of negative numbers will be positive while multiplying odd numbers of negative numbers will be negative. In this case, as there are seven negative numbers, the multiplied result of these seven will be negative. However, when you multiply this negative number by eight positive numbers, the final impact will be negative since any number (except 0), when multiplied by a negative number, results in a negative number. So, the product of 7 negative numbers and eight positive numbers will be negative.
