Final answer:
You can tell that the first digit of the quotient of 2,874 divided by 3 is in the hundreds place by using estimation and recognizing that 287 (the first three digits) is greater than 3 multiplied by 100, thus ensuring the quotient reaches the hundreds place.
Explanation:
To determine if the first digit of the quotient of 2,874 divided by 3 is in the hundreds place before actually dividing, we can use an estimation technique. Estimation helps us to predict the placement of the quotient's digits without doing the full calculation. For the divisor 3 to produce a number in the hundreds place, it must be able to go into the first three digits of the dividend (here, 2,874).
We look at the thousands and hundreds places of the dividend. Since the number 2,874 has a 2 in the thousands place, we know 3 cannot be divided into 2 to give us a number in the hundreds place. But when we include the next digit in the hundreds place, we have 287, which is greater than 3 imes 100. Therefore, we can say that 3 will go into 287 at least 100 times, making the first digit of the quotient in the hundreds place.
This estimation is further validated by the recognition that the number in the hundreds place of 2,874 (which is 8) is more than twice 3, and therefore, dividing it by 3 will definitely yield a number greater than 100 but less than 1,000.

Answer:
Option d) [tex](4-x^5)(16+x^{10}+4x^5)[/tex]
Step-by-step explanation:
We are given the following in the question.
[tex]64-x^{15}[/tex]
We have to factorize the given expression.
Using the algebraic identity:
[tex]a^3 - b^3 = (a-b)(a^2+b^2+ab) = (a-b)^3 +3ab(a-b)[/tex]
[tex]64-x^{15}\\\\(4)^3 - (x^5)^3\\\\(4 - x^5)(4^2 + (x^5)^2 + 4x^5)\\\\(4-x^5)(16+x^{10}+4x^5)[/tex]
Hence, the factors of given expression is given by option d) [tex](4-x^5)(16+x^{10}+4x^5)[/tex]
The average rate of change from x = 0 to x = 15 is about −4.667. How does the average rate of change from x = 0 to x = 20 compare to this number?
Suppose that the height of the slide is 2 feet, when x = 20. What is the average rate of change over the entire slide?
The average rate of change over the entire slide is -0.05.
The average rate of change from x = 0 to x = 15 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 15.
The slope of the secant line is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (-2 - 15)/(15 - 0)
= -17/15
= -1.133
The average rate of change from x = 0 to x = 20 is calculated by finding the slope of the secant line that intersects the graph of the function at x = 0 and x = 20.
The slope of the secant line is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (2 - 15)/(20 - 0)
= -13/20
= -0.65
The average rate of change from x = 0 to x = 20 is smaller than the average rate of change from x = 0 to x = 15.
This is because the slope of the secant line is getting closer to 0 as the interval gets larger.
If the height of the slide is 2 feet when x = 20, then the average rate of change over the entire slide is:
m = ([tex]y_2[/tex] - [tex]y_1[/tex])/([tex]x_2[/tex] - [tex]x_1[/tex])
= (2 - 1)/(20 - 0)
= -1/20
= -0.05
The average rate of change over the entire slide is also negative, but it is much smaller than the average rate of change from x = 0 to x = 15.
This is because the slope of the secant line is getting closer to 0 as the interval gets larger.

You buy 8 packs of markers with 20 markers in each pack. You already had 10 markers. Which equation shows how to calculate the total number of markers, m, you have?
Answer: [tex]m= 8(20)+10[/tex]
Step-by-step explanation:
Given : The number of markers in each of 8 pack = 20
Then, the number of markers in 8 packs = 8 x 20 = 8(20)
Also, You already had 10 markers.
Then, the total markers you have now = Number of markers in 8 packs+ 10
= 8(20)+10
If we denote the total number of markers be 'm'.
Then, the required equation will be :-
[tex]m= 8(20)+10[/tex]
Hence, the equation shows how to calculate the total number of markers, m, you have : [tex]m= 8(20)+10[/tex]

Is the system of equations is consistent, consistent and coincident, or inconsistent? y=4x−4 y=−4x+4 Select the correct answer from the drop-down menu.
If a system has exactly one or infinite number of solutions then it will be a consistent system.
So, we can solve the given system of equation to get the answer.
y=4x−4 ................(1)
y=−4x+4...............(2)
After equating both the equations we will get,
4x-4= -4x+4
4x-4+4x=4 (Adding 4x to each sides).
8x-4=4
8x=4+4 (Adding 4 to each sides).
8x=8
8x/8=8/8 ( Dividing each sides by 8).
x=1
Now pluging x=1 in equation (1). So,
y=4x−4
=4(1)-4
=4-4
=0
Hence the solution of the given system is (1, 0) which also means that the two equations is intersecting at a point(1,0).
So, the given system is consistent and coincident.
Answer:
The answer is " Consistent And Independent"
Why? :
When 2 Lines intersect at one point it means it Consistent and Independent
and When the Lines are the same exact thing its Consistent and Dependent
But, when 2 lines don't intersect at all its inconsistent. :)

Gabriel wants to solve the equation 5/8 m=25. What step should he do to get m by itself on one side of the equation?
Final answer:
To solve the equation 5/8 m = 25, Gabriel needs to multiply both sides of the equation by the reciprocal of 5/8, which is 8/5, to isolate m on one side. The result after simplification is m = 40.
Explanation:
To solve the equation 5/8 m = 25, Gabriel needs to isolate the variable m on one side of the equation. He should start by multiplying both sides of the equation by the reciprocal of the fraction that is multiplied by m, which is 8/5. Here's the step-by-step process:
Multiply both sides of the equation by 8/5 to cancel out the 5/8 on the left side:
(8/5) × (5/8) m = (8/5) × 25
Simplify the left side by canceling out the common factors in the fraction:
1 m = (8/5) × 25
Next, multiply the number 25 by 8/5 to find the value of m:
m = 25 × (8/5) = 40
Thus, the solution to the equation is m = 40.

Jamal drew the function below. Which explains whether or not his function is linear?
A. It is linear because it has a constant rate of change.
B. It is linear because it does not have a constant rate of change.
C. It is not linear because it has a constant rate of change.
D. It is not linear because it does not have a constant rate of change.
Answer:
A. It is linear because it has a constant rate of change.
Step-by-step explanation:
A straight line graph is possible between two variables x and y only if there is a constant rate of change
y = mx+b is the equation of a straight line in general and here we find rate of change of y with respect to x is constant m which does not depend on x or y.
In other words, throughout the domain a straight line has constant slope.
Here we find that the graph given is a straight line.
Hence option A is suitable answer
A. It is linear because it has a constant rate of change.

Ellen is drawing two polygons one of the polygons has 3 more angles than the other what shape could she be drawing
Answer:
Step-by-step explanation:
The attachment shows different types of polygons.
Now depending on these we have following five possibilities:
Case 1: Triangle and hexagon
If first polygon is triangle with three angles, the second will have 6 angles and the second polygon will be hexagon.
Case 2: Quadrilateral and heptagon
If first polygon is quadrilateral with 4 angles, the second will have 4+3 =7 angles and the second polygon will be heptagon.
Case 3: Pentagon and Octagon
If first polygon is pentagon with 5 angles, the second will have 5+3=8 angles and the second polygon will be octagon.
Case 4: Hexagon and Nonagon
If first polygon is hexagon with 6 angles, the second will have 6+3=9 angles and the second polygon will be nonagon.
Case 5: Heptagon and Decagon
If first polygon is Heptagon with 7 angles, the second will have 7+3=10 angles and the second polygon will be decagon.
Depend on the possibilities, which figure Ellen is drawing.
What is polygon?A closed, two-dimensional form with straight line segments is called a polygon. It does not have three dimensions. A polygon has flat surfaces throughout. A polygon must have three sides at a minimum. Only at its terminal must each side of a line segment cross another line segment. Depending on a polygon's number of sides.
Given Ellen is drawing two polygons one of the polygons has 3 more angles than the other,
Now, based on these, there are the five options listed below:
Case 1: Hexagon and triangle
If the first polygon is a triangle with three angles, the second polygon will be a hexagon with six angles.
Case 2: Heptagon and quadrilateral
If the first polygon has a quadrilateral shape and four angles, the second polygon will have four plus three more angles, making it a heptagon.
Pentagon and Octagon in Case 3
If the first polygon has a pentagon shape with five angles, the second will have an octagon shape with five plus three equals eight angles.
Hexagon and Nonagon in Case 4
If the first polygon has a hexagon shape and 6 angles, the second will have 6 + 3 = 9 angles and be a nonagon.
Heptagon and Decagon in Case 5
if the initial polygon is a hexagon, then The first polygon has 7 angles, the second has 7+3=10 angles, and the third is a decagon.
Hence the shape of polygon depend on these possibilities.

A. $829.23
B. $884.56
C. $807.81
D. $876.09
Answer:
B . $ 884.56
Step-by-step explanation:
Since, monthly payment formula of a loan,
[tex]P=\frac{PV(\frac{r}{12})}{1-(1+\frac{r}{12})^{-12t}}[/tex]
