a. Adding the same number to two numbers produces the same result. Example: 4 + 3 = 7, 7 + 3 = 10, b. Commutative Property: Order does not matter. Example: 4 + 7 = 7 + 4.
The Density Property of Real Numbers states that between any two real numbers, there are an infinite number of other real numbers. This means that for any two real numbers, no matter how close or far apart they are, there is always a third number between them. An example of this property would be if we have two numbers, 4 and 7. If we add 3 to each of these numbers, we will get the same result. 4 + 3 = 7, and 7 + 3 = 10. This shows that no matter what two real numbers we pick, there will always be a third number between them, and when we add the same number to both of them, we will get the same result. Another property of numbers is the Commutative Property, which states that the order of the numbers doesn’t matter when performing certain operations. For example, when adding two numbers, 4 + 7 = 7 + 4. This means that it doesn’t matter which number comes first when adding. This property applies to other operations as well, such as multiplication, division, and subtraction.

henry's score on an accounting exam placed him in the 85th percentile in the class. what percentage of students scored higher than henry?
15% of the students scored higher than Henry on the accounting exam.
What is percentiles?
Percentiles are a measure of the relative standing of a value within a set of values. The nth percentile is a value such that n% of the values are less than or equal to that value.
So, if Henry's score is in the 85th percentile, it means that 85% of the scores in the class are less than or equal to his score.
Therefore, 100% - 85% = 15% of the scores in the class are higher than Henry's score. So, 15% of the students scored higher than Henry on the accounting exam.

The perimeter of the 6-sided shape given the length and width of the rectangle is 48 cm
What is the perimeter of the 6-sided shape?The perimeter of a rectangle= 2(length + width)
Length of the rectangle= 7 cm
Width of the rectangle= 5 cm
The perimeter of a rectangle= 2(length + width)
= 2(7 + 5)
= 2(12)

Using the graph of the function, the value of f(4) is 6.
How to find the value of f(4) of the graph?A function is an expression that shows the relationship between the independent variable and the dependent variable. A function is usually denoted by letters such as f, g, etc.
The set of inputs is called the domain of the function, and the set of outputs is called the codomain. A function maps each input to exactly one output, so it is also sometimes referred to as a mapping.
Using the graph, the value of f(4) can be found by checking for the value y when x = 4. Check the attached image.

Determine the experimental probability of not selecting a heart.
P(not heart) = 9%
P(not heart) = 10%
P(not heart) = 67.5%
P(not heart) = 77.5%
Step-by-step explanation:
a probability is always the ratio
desired cases / totally possible cases
in our experiment the totally possible cases for pulling not a heart is 40.
7 + 11 + 9 + 13 = 40
in that experiment we see that out of these 40 pulls we got 9 hearts. and therefore 40 - 9 = 31 non-hearts.
so, the experimental probability for not pulling a heart is
31/40 = 0.775 = 77.5%

i am equivalent to 5/6 . the sum of my numerator and my denominator is 44. the sum of the digits in my denominator is 6. what fraction am i?
The fraction that satisfies the problem is 20/24.
Equivalent fractions are fractions that have the same value, but different numerators and denominators.
If the fraction is equivalent to 5/6, then the numerator and denominator of the fraction is a multiple of 5 and 6, respectively.
Let x be the factor
fraction = 5x / 6x
If the sum of my numerator and my denominator is 44, then:
5x + 6x = 44
11x = 44
x = 4
fraction = 5x / 6x = 20/24

Step-by-step explanation:
All the real solutions of f(x) = 0 are 4, -2, and -5. We know y = f(x) and f(x) = 0. So, we can conclude that y = 0. When y = 0, it means there isn't a point that moves up or down the y axis (vertically). The point would only move horizontally. When looking at the points on the x-axis, we see 4, -2, and -5. Those are on the x-axis and haven't moved vertically. So, the coordinates for those points would be 4, 0, -2, 0, and -5, 0. Remember, y = 0, and 4, -2, and -5 all have a zero in the y value. Therefore, the answer is 4, -2, and -5.

The new mandated change is, grade 4N's physical education class will end at 2:23 PM.
Physical education for grade 4N typically lasts 30 minutes and begins at 1:43 PM and concludes at 2:13 PM (2:13 PM - 1:43 PM).
Let's assume that the newly required adjustment extends the end of the class by 10 minutes, making the time change (c) 10 minutes.
Adding the time modification to the existing end time will yield the new end time:
2:13 PM + 10 minutes = 2:23 PM

Given that the length of the candle on day 1 is 18 inches, we have:
L = 18
And the length of the candle on day 5 is:

what is linear equations ?In math, a linear equation one of that of the form y=mx+b. The slope is B, and the una is m. As y and x are variable, the previous statement is frequently referred to as a "system of equations with 2 variables." Bivariate linear equations are logistic equations with two or more variables. Formulas can be found in various locations, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When such an equation has had the structure y=mx+b, where m represents the slope and b its y-intercept, it is known to as being linear. A model formula is said to be cubic if its solution seems to have the form y=mx+b, wherein m stands for the gradient and b for the y-intercept.
3x + 4y = 38
x + y = 12 ( Multiply by -3)

a pyramid is 860 ft high (due to erosion, its current height is slightly less) and has a square base of side 7740 ft. find the work needed to build the pyramid if the density of the stone is estimated at 168 lb/ft .
The work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone.
The work needed to build the pyramid can be calculated by using the formula Work = Area x Height x Density. The area of the base of the pyramid can be calculated by using the formula Area = Side^2, where Side is the length of the side of the square base. In this case, the side of the square base is 7740 ft. So, the area of the base is 7740^2 ft^2. The height of the pyramid is 860 ft (due to erosion, its current height is slightly less). The density of the stone is estimated at 168 lb/ft. So, the work needed to build the pyramid is calculated by multiplying the area of the base by the height and the density of the stone, like this: Work = 7740^2 ft^2 x 860 ft x 168 lb/ft = 9.76 x 10^9 lb-ft.
