Which are the best definitions for theorem, conjecture, and axiom?
A statement that is assumed to be true without proof is a(n)
. A statement that has been shown to be true by vigorous application of logic is a(n)
. A(n)
is a statement that is believed to be true but hasn't been proven.
A statement that is assumed to be true without proof is a(n) Theorem
A statement that has been shown to be true by vigorous application of logic is a(n) ---> Conjecture
A(n) Axiom is a statement that is believed to be true but hasn't been proven.
What's the big difference between a definition and a theorem?A definition is both a precise and a general statement of the significance of a mathematical term.
It does this by laying down all of the characteristics of the word together with the structures that need to be true.
This is how the meaning of the word is defined. A mathematical assertion that can be demonstrated using logically sound mathematical reasoning is called a theorem.

True value received an invoice dated may 08, 2020. the invoice had a $5,800 balance that included $800 freight. terms were 3/10, 2/30, n/60. true value pays the invoice on may 22. what amount does true value pay?
True value received an invoice dated may 08, 2020. the invoice had a $5,800 balance that included $800 freight true value pays the invoice on may 22. then true value pay amount is $4900
Invoice dated 08/may/2020. Amounting to $5,800 which includes $800 freight.
Terms:
3/10 ; 2/30 ; n/60
The term 3/10 means that True value can avail of 3% discount if it pays within 10 days from date of issuance. The 10th day would be 18/may/2020
The term 2/30 means that True value can avail of 2% discount if it pays from the 11th day up to the 30th day from the date of issuance.
may 22 is beyond the 10th day but within the 30 days discount period. True Value can avail of the 2% discount.
5,800 - 800 = 5,000 The freight can't be subjected to discount thus it is deducted from the total invoice amount.
5,000 * 2% = 100
5,000 - 100 = 4900 amount True Value has to pay.

what is the maximum number of balls of clay of radius 2 that can completely fit inside a cube of side length 7 assuming the balls can be reshaped but not compressed before they are packed in the cube?
Answer:
Number of balls of clay: 10
Step-by-step explanation:
The volume of the cube is [tex]$V_{\text{cube}}=7^3=343,$[/tex]
and the volume of a clay ball is: [tex]$V_{\text{ball}}=\frac43\cdot\pi\cdot2^3=\frac{32}{3}\pi.$[/tex]
Since the balls can be reshaped but not compressed, the maximum number of balls that can completely fit inside a cube is
[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor=\left\lfloor\frac{343}{\frac{32\pi}{3} }\right\rfloor.\][/tex]
Approximating with [tex]$\pi\approx3.14[/tex]
We have:
[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor=10.23565228[/tex]
We simplify to get:
[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor\approx10[/tex]
So:

Solve the following...
4x+10=-26
Answer:
x = -9
Step-by-step explanation:
the goal is to get x by itself, so subtract 10 from both sides: 4x=-36
divide both sides by 4: x = -9
|-----4x+10=-26 |
|ANSWER= x=-9-------|
happy fall!
explanation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When we have questions like this, and the x is just THROWN in there, we have to "combine our like terms."
STEP ONE ✨: "How do we do that..if one is on the other side?"
We have to make it disappear. +10-10 equals zero, right? right! So do that!
4x+10=-26
-10
But what we do to one side, we do to the other! Subtract 10 from the numbers on the equal side.
4x+10=-26
-10 -10
-26-10
4x=-36
STEP TWO : What do we do when a number has an X beside it?
Since this number is being multiplied to the x, we have to DIVIDE the 4x by 4, so we just get the x alone. It always works like this. Don't doubt yourself!!
4x=-36
/4 /4
-36/4=-9
x=-9!

Ella walks to the art store at 2mph, but returns home at 4 mph. If her total walking time is 1/2 an hour, how far away is the art store? Express your answer as a fraction.
The distance of art store from Ella's house is 2/3 miles or 0.67 miles.
It is a question of time, speed and distance.
It is given in the question that Ella walks to the art store at 2mph, but returns home at 4 mph.
Also, the total time taken by Ella to cover the journey is 1/2 an hour.
We have to find the distance of art store from Ella's house.
Let the distance from Ella's house to art store be d miles.
We know that,
Speed = distance/time
Time = distance/speed
Hence, we can write,
time = d/2 (walking to the art store from from)
Also,
time = d/4 (walking to home from the art store)
Hence,
d/2 + d/4 = 1/2
3d/4 = 1/2

Median is the number that is at the center of the dataset that is arranged in either ascending or descending order.
Median of Class 1 = (86 + 90) / 2 = 88
Median of Class 2 = (84 + 87) / 2 = 85.50
Median of Class 3 = (76 + 80) / 2 = 78
Mode is the number that occurs most frequently in a dataset.
Standard deviation is used to calculate the average variation of a dataset.
Standard deviation = [tex]\sqrt{\frac{(x - u)^{2} }{n} }[/tex]
Where:
x = number in the dataset u = mean n = total numbers in the dataset.Standard deviation of Class 1 = 18.81

Dante buys candy that costs $7 per pound. He will spend at least $42 on candy. What are the possible numbers of pounds he will buy? Use p for the number of pounds Dante will buy. Write your answer as an inequality solved for p
Answer:
p [tex]\geq[/tex] 6
Step-by-step explanation:
If one pound costs $7 and he's going to spend at least $42, then he will buy at least as many pounds as what costs $42.
42 divided by 7 equals 6, so he will buy at least 6 pounds of candy.
Three consecutive positive odd integers such that 5 times the square of the
middle integer exceeds the product of the other two by 488.
By letting the smallest integer equal x, set up and solve a quadratic equation
to find the middle integer.
A solution by trial and improvement will not be accepted.
An analogous equation can be created by factoring a quadratic equation. 5x^2 = (x-2) * (x+2) + 488 can give integers 9, 11,13.
What is a quadratic equation?In algebra, quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as
[tex]{ax^{2}+bx+c=0}[/tex]
where a 0 and x denotes an unknown and a, b, and c denote known numbers, Since there is no ax2 term, the equation is linear (and not quadratic) if a = 0 (and b 0). The coefficients of the equation, denoted by the numbers a, b, and c, are the quadratic coefficient, linear coefficient, and constant or free term, respectively.
The roots or zeros of the expression on the left-hand side of the equation are the values of x that fulfill the equation. There can only be two solutions to a quadratic problem. One claims that a problem is a double root if there is just one solution. There are either two real solutions, one real double root, two complex solutions that are complex conjugates of one another, or two real solutions if all the coefficients are real values. If complex roots are included, a quadratic equation will always have two roots; a double root counts as two. An analogous equation can be created by factoring a quadratic equation.
According to the formula, if 5x2 = x2 - 4 + 488, then 5x2 = x2 + 484.
For 4x2 = 484, subtract x2 from each side, resulting in x2 = 121.
For x = 11, square root each side.
TEST: 5*121 = 9*13 + 488, so 605 is equal to 117 plus 488.
The middle odd number, x, is equal to 11.
The figures are 9, 11, and 13.

The matchings are:
3x - y = -5 ⇒ table C.
x - 3y = 12 ⇒ table A.
3x - y = -2 ⇒ table D.
2x - 3y = 9 ⇒ table B.
How to match each equation to the correspondent table?The first equation we have is:
3x - y = -5
Evaluating in x = 0, we have:
3*0 - y = - 5
y = 5
So we have the point (0, 5).
Evaluating in x = -2 we get:
3*-2 - y = -5
6 + y = 5
y = 5 - 6 = -1
So we have the point (-2, -1)
The only table with that point is table C, so we conclude that it is the correct option.
2) The second equation is:
x - 3y = 12
Evaluating in x = 0 we get:
0 - 3y = 12
y = 12/-3 = -4
So we have the point (0, -4)
if x = 3 we have:
3 - 3*y = 12
-3*y = 12 - 3 = 9
y = 9/-3 = -3
So we have the point (3, -3)
The only table with these two points is table A, so that is the correct one.
3) The next equation is:
3x - y = -2
The tables left are B and D.
Now, let's evalaute this equation in x = 3.
3*3 - y = -2
9 - y = -2
9 + 2 = y
11 = y
So we have the point (3, 11)
Notice that on table B,the value associated to x = 3 is y = -1, so we discard table B, and we conclude that this equation relates to table D.
Trivially, the last equation:
2x - 3y = 9
Matches table B.
