An empty number line is a visual tool used to represent numbers and their relative positions. It can be used to compare, order, and perform operations on numbers.
How to learn and understand comparison of numbers?A number with more digits is always greater than a number with fewer digits, according to Rule I.
Rule II states that when two numbers have the same number of digits, we compare the digits starting from the leftmost position until we find an unequal number of digits. Greater numbers are those with more digits.
As far as we are aware, a number with more digits is always greater than one with fewer digits.
The sum of the first two digits is bigger than the sum of the first one.The number with three digits is larger than the number with two or one.A four-digit number has more digits than a three-, two-, or one-digit number.A five-digit number over a four-digit number.

Answer:
D
Step-by-step explanation:
Find an ordered pair (x, y) that is a solution to the equation.
-x+2y=7
(x, y) = (_, _)
To answer this, you get to pick any x-value and then solve for y OR you can pick any y-value and solve for x.
For this one, let's pick x = 3. We'll then substitute 3 in for x in the equation:
- (3) + 2y = 7
and then solve for x:
-3 + 2y = 7
Add 3 to both sides:
2y = 10
Divide by 2 on both sides:
y = 5
This shows that (3,5) is a solution for the equation.
Again, you could pick any x-value and solve for y OR pick any y-value and solve for x. There are an infinite number of solutions.

Assuming a Perfectly Competitive firm has the following cost function: TC = 1000 + 600Q – 10Q2 + 0.05Q3 . Minimum AVC is
Therefore , to calculate the average AVC, use the formula: TC at 0 output is 5, which equals fixed cost (FC) of 5.
How are AVC, AFC, and TC calculated?The fixed cost per unit of output is known as the AFC, and the variable cost per unit of output is known as the AVC. We previously stated that Bob's Bakery can produce 100 loaves with FC = 40, VC = 500, and TC = 540. ATC = TC/Q = 540/100 = 5.4 as a result. Additionally, AVC = 500/100 = 5 and AFC = 40/100 = 0.4.
Here,
Total cost is equal to total fixed cost plus total variable cost, or TC.
In order to obtain the VC at each output, we must first subtract 5 from the TCs for all subsequent output levels.
AVC is now equal to VC divided by Q.

Using Squeeze/Sandwich Theorem,
Calculate the limit of : lim [(x,y) -> (0,0)] (3 . x^2 . y / (x^2 + y^2))
Using Squeeze theorem, the limit of the function is 0
What is the LimitThe Squeeze Theorem states that if f(x,y) <= g(x,y) <= h(x,y) for all x,y in a region around (x0,y0) and lim (x,y)->(x0,y0) g(x,y) = L, then lim (x,y)->(x0,y0) f(x,y) = lim (x,y)->(x0,y0) h(x,y) = L.
We can use the Squeeze Theorem to find the limit of the given function by finding two other functions that bound it and have known limits as (x,y) approaches (0,0).
We can see that
(x^2+y^2)/(x^2+y^2) <= 3x^2y/(x^2+y^2) <= (3xy)/(x^2+y^2)
As x,y approaches 0, the first inequality approaches 1 and the second one approaches 0, so the limit of the given function is also 0.
Therefore, lim [(x,y) -> (0,0)] (3 . x^2 . y / (x^2 + y^2)) = 0.

b) Three interior angles of an n-sided polygon are 136', 138' and 146'. The remaining angles are 165' each. Find the value of n.
By solving a linear equation we will see that the polygon has 19 sides.
How to find the number of sides of the polygon?Remember that for a polygon of n sides, the sum of the interior angles is equal to:
(n - 2)*180°
Here we also know that 3 angles are:
136°, 138°, and 146°
And the rest of the angles (n - 3) angles are of 165° each.
Then the sum of the interior angles gives:
136° + 138° + 146° + (n - 3)*165°
And that must be equal to the expression above, so we can write the linear equation:
136° + 138° + 146° + (n - 3)*165° = (n - 2)*180°
420° + n*165° - 495° = n*180° - 360°
n*165° - 75° = n*180° - 360°
360° - 75° = n*180 - n*165
285° = n*15°
285°/15° = n
19 = n

Answer:
Mean: [tex]14 \frac{11}{207}[/tex]
Median: 14.5
Mode: 6, 13, and 15
Step-by-step explanation:
We will start by arranging these numbers from smallest to greatest to get the median and mode:
6, 6, 11, 12, 13, 13, 14, 15, 15, 17, 19, 20, 22, 24
To get the mode, we will look. There are two 6, 13, and 15. So those three are our modes. Then, since there are 14 numbers, we will split the list in half and find the average of the two most inward numbers. We get:
6, 6, 11, 12, 13, 13, 14 15, 15, 17, 19, 20, 22, 24
Our two most inward numbers are 14 and 15, so we add the two together and then divide by 2, giving us:
14 + 15 = 29/2 = 14.5
So our median is 14.5.
Finally, we will add up all the numbers together, then divide by 14 to get our mean. We get:
6 + 6 + 11 + 12 + 13 + 13 + 14 + 15 + 15 + 17 + 19 + 20 + 22 + 24 = 207
Then we divide by 14:
[tex]\frac{207}{14} = 14 \frac{11}{207}[/tex]
So, our median is [tex]14 \frac{11}{207}[/tex].

If the brain volumes (cm³) of 20 brains have a mean of 1085.2 cm³ and a standard deviation of 125.6 cm³. For such data: it is significantly low for a brain because 1386.4 cm³ is less than the upper limit.
How to find the lower and upper limits?Mean = 1085.2 cm³
Standard deviation = 125.6 cm³
Hence,
Lower limit = Mean - 2 x Standard deviation
Lower limit =1085.2 - 2 x 125.6
Lower limit =1161.2 - 251.2
Lower limit =910
Upper Limit = Mean + 2 x Standard deviation
Upper Limit = 1161.2 + 2 x 125.6
Upper Limit =1161.2 +251.2
Upper Limit =1412.4
The limit of values is from 910 to 1412.4.

A population of pea aphids doubles every week. The population begins with 300 individual pea aphids. In how many weeks will the population reach 9,600 individuals?
Answer:
To find out how many weeks it will take for the pea aphid population to reach 9,600 individuals, we need to determine how many times the population needs to double to reach that number.
We can use logarithms to find this out. Using the rule log(A) / log(B) = log(A) to base B, we can calculate the number of times the population needs to double.
log(9600) / log(2) = log(9600) to base 2 = 9.98
So the population needs to double 9.98 times.
Since the population doubles every week, it will take 9.98 weeks for the population to reach 9,600 individuals.

Answer: 5 weeks
Step-by-step explanation: Based on the information given, let's conduct an equation. It'd look something like this:
300 * [tex]2^{x}[/tex] = 9600
Now, we need to "reduce" the greatest common factors on both sides of the equation. This is so we can find the value of "x" It should look like this:

16 People fit comfortably in a 8 feet by 9 feet area. Use this value to estimate the size of a crowd that is
5 feet deep on both sides of the street along a 2-mile section of a parade route.
Answer:
Step-by-step explanation:
It is impossible to accurately estimate the size of the crowd without knowing how many people are standing in each foot of space. However, if we assume that 16 people fit in a 9 ft x 8 ft area, then we can estimate the size of the crowd in a 2-mile section of the parade route that is 5 feet deep on both sides of the street.
Assuming a 5-foot deep crowd on both sides of the parade route, we can estimate that there would be 40 feet of crowd on one side of the parade route and 40 feet of crowd on the other side of the parade route. This means that there would be a total of 80 feet of crowd across the 2-mile parade route.
Using the assumption that 16 people fit in a 9 ft x 8 ft area, we can estimate that there would be 1280 people across the 2-mile parade route (80 feet x 16 people). This is a rough estimate, as it does not account for the gaps between people, which would likely reduce the total number of people in the parade route.

Winston leaned a 32-foot ladder against the side of a building. The
base of the ladder is 3 feet from the base of the building. The top of
the ladder is 15 feet from the top of the building. How tall is the
building? Provide an answer accurate to the nearest tenth of a foot.
Answer:
the building is approximately 28.3 feet tall, accurate to the nearest tenth of a foot.
Step-by-step explanation:
The height of the building can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the building is the hypotenuse, and the base of the ladder and the top of the ladder form the other two sides.
The height of the building can be found using the following formula:
h = √(32^2 - 15^2)
h = √(1024 - 225)
h = √(799)
h ≈ 28.3 ft
