the largest alligator ever caught in Mississippi weighed 727 pounds?
The answer is false. The alligator caught in Mississippi actually weighed 766.5 pounds.
The largest alligator ever recorded and taken in the state of Mississippi weighed 727 pounds. This is an exceptional case, as alligators usually weigh less.
Explanation:Yes, the largest alligator ever recorded and caught in the state of Mississippi weighed 727 pounds. This monumental creature stands as a testament to the potential size that members of the alligator species can achieve under optimal conditions. It's always imperative to understand that different species have varied weight standards, and this is no exception when it comes to alligators. While 727 pounds may seem extraordinarily large, it's important to note that it is an extreme and not the norm for the species.

The expression −7x + x³ −6 + x² written in standard form is x³ + x² −7x −6.
Standard form for polynomials is written from the highest degree to the lowest degree of the variables. So, the given expression −7x + x³ −6 + x² should be rearranged as follows:
Identify the term with the highest exponent, which is x³.
Then order the remaining terms by decreasing powers of x: x² comes next, followed by −7x.
Finally, position the constant term at the end, which is −6.
Putting it all together, the polynomial in standard form is x³ + x² −7x −6.

Rafael is taking a test that contains a section of 12 true-false questions. How many of the possible groups of answers to these questions have exactly 8 correct answers of false? a. 425 c. 500 b. 495 d. 515
Answer: 495
==============================================================
We want exactly 8 correct answers of false, so we want exactly 4 correct answers of true. In short, we want something like FFFF FFFF TTTT. Because the sequence of T values is shorter than the F values, this means it's a lot easier to count out the number of ways to pick the true responses, rather than the false responses.
Consider we have 4 slots: A, B, C, D
In slot A, we can pick the number 1 through 12 to represent getting a T
For slot B, we have 11 choices because we can't reuse whatever we picked for slot A
Then for slot C we have 10 choices
Finally, slot D has 9 choices
Multiply those values out: 12*11*10*9 = 11,880
If order mattered, then we'd be done with the problem. However, order does not matter. This is because a sequence like {1, 2, 3, 4} is the same as {1,2,4,3}. The only thing that matters is that we have the numbers in the same group. We can rearrange any given group however we want.
Note that there are 4! = 4*3*2*1 = 24 ways to arrange any individual group of four items. So we have to divide the previous result 11,880 by 24 and we get: 11880/24 = 495 which is the answer
If you wanted, you can use the nCr combination formula to get this same answer. You would use n = 12 and r = 4

the volume of a cube is 64 cubic inches. what is the length of one side?
To solve for the volume of the cube, you must use the formula:
Volume = a³
"a" being an edge.
Plug in 64 for Volume
64 = a³
Note the equal sign. What you do to one side, you do to the other. Cube root both sides
∛64 = ∛a³
a = ∛64 = 4
4 inches is your answer
hope this helps
To find the length of one side of a cube with a volume of 64 cubic inches, take the cube root of the volume, which results in a side length of 4 inches.
The volume of a cube is found by cubing the length of one of its sides since a cube's sides are all equal in length. For a cube with a volume of 64 cubic inches, you can find the length of one side by taking the cube root of 64.
Steps to determine the length of one side of the cube:
Understand that the volume of a cube (V) is equal to the side length (s) cubed: V = s³.Since the volume is 64 cubic inches, set up the equation 64 = s³.Take the cube root of both sides of the equation to find s:What is the measure of each exterior angle for a regular nonagon
The sum of the exterior angles of any polygon is 360 degrees. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees. its my best guess
In a regular nonagon, each exterior angle measures 40 degrees.
A regular nonagon is a polygon that has nine sides of equal length and nine interior angles of equal measure.
To determine the measure of each exterior angle for a regular nonagon, you can follow these steps. Recall that a nonagon is a polygon with nine sides. The sum of the exterior angles of any polygon is always 360 degrees.
Divide the sum of the exterior angles (360 degrees) by the number of sides in the nonagon (9) to find the measure of each exterior angle.
Calculate: 360 degrees ÷ 9 = 40 degrees.
Therefore, each exterior angle in a regular nonagon measures 40 degrees. This means that if you were to extend one side of a regular nonagon outward, the angle formed between that extended side and the adjacent side would measure 40 degrees.

Answer:
32.48 and 32.50 is the numbers which are more than 32.46 and less than 32.56 and there difference is 0.02
Step-by-step explanation:
We have given two numbers 32.46 and 32.56
We have to find two numbers which are greater than 32.46 but less than 32.56
The number 32.48 is greater than 32.46 and less than 32.56
And other number 32.50 is greater than 32.46 and less than 32.56
Now we have to find the difference of these two numbers
So difference = 32.50 - 32.48 = 0.02
The two numbers that are greater than 32.46 and less than 32.56 are 32.48 and 32.54.
The difference between the two numbers is 0.06.What is the difference of your two numbers?

find a counter example to following bad definition: a square has four right angles
a flat figure with 4 equal straight sides and four right angles
Answer: Hello there!
We want to find a counterexample to: "a square has four right angles" then we need to find a figure that has four right angles and is not a square.
A first example can be a cross (two segments that cut each other and are perpendicular), but let's think in a geometric shape.
Think on a square that in the middle of each side has a small semicircle; this shape still has four right angles but is not more a square.
There you have two counterexamples of the definition given.

What is the smallest 3-digit number that has 2, 3, and 7 among its prime factors?
Answer: 126
Step-by-step explanation: You would just find the LCM (2, 3, 7) and get 42. But since you need a 3-digit number, list the multiples of 42, like so: 42, 84, 126, 168, 210...
As you can see, 126 is the smallest 3-digit number that has 2, 3, and 7 among its prime factors.
The smallest 3-digit number that has 2, 3, and 7 among its prime factors is 126.
Explanation:
The smallest 3-digit number that has 2, 3, and 7 as its prime factors can be calculated by multiplying the prime factors together. In this case, it's 2 x 3 x 7, which equals 42. This is a 2-digit number, but we're looking for
3-digit
number. The next multiple of 42 (42 x 3) gives us 126, which is a 3-digit number. So, the

Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.
So instead it should be 0÷(-7)=0
Helen's assertion that division by 0 results in 0 is incorrect. Her error lies in a fundamental mathematical principle: division by zero is undefined in arithmetic.
How to determine Helen errorDividing any number by 0 is mathematically impossible and not meaningful. It does not yield a value of 0 or any other number because the concept is not valid in standard arithmetic. When you attempt to divide by 0, you encounter mathematical inconsistency and contradiction.
In mathematics, there are well-defined rules and operations for manipulating numbers, and division by zero does not adhere to these rules.

he saves $860 per month
calculate each of his outgoings
rent = [tex]\frac{1}{4}[/tex] × $3600 = [tex]\frac{3600}{4}[/tex] = $900
food = [tex]\frac{2}{5}[/tex] × $3600 = [tex]\frac{2(3600)}{5}[/tex] = $1440
activities = [tex]\frac{1}{9}[/tex] × $3600 = [tex]\frac{3600}{9}[/tex] = $400
savings = $3600 - ( 900 + 1440 + 400 ) = $860
To add the fractions we must make the denominators = 180.
45/180 + 72/180 + 20/180 = 137/180
Expense Total = (137/180) * 3,600 = $2,740
