what's a factor in math
Answer:
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
Tell whether the difference of two positive integers is always, sometimes, or never positive.
The difference of two positive integers is sometimes positive.
How to illustrate the information?For example the difference of 3 and 5 will give a value of -2. This is negative.
On the other hand, the difference of 10 and 6 is 4. Therefore, this is positive.
Therefore, the difference of two positive integers is sometimes positive. It can also be negative.

The amount left when Joshua played two basketball hoop games for $3.25 each and four rounds of air hockey for $1.75 each is A. $4.50.
How to calculate the value?From the information, Joshua purchased a game card for the arcade for a total of $18 and played two basketball hoop games for $3.25 each and four rounds of air hockey for $1.75 each.
Therefore, the amount left will be:
= Total amount with him - Amount spent
= $18 - (2 × $3.25) - (4 × $1.75)
= $18 - $6.50 - $7
= $4.50
The amount left is $4.50

For an analysis of variance comparing four treatments, msbetween = 12. The value of ssbetween is 36.
What is variance ?A measure of variability is the variance. It is determined by averaging the squared deviations from the mean. Your data set's variability is shown by its variance. The variance is greater in respect to the mean when the data are more dispersed.
Finding the mean will allow you to compute the population's variance (the average). Squaring the result after deducting the mean from each data point in the sample. The outcomes are squared to make the adverse findings positive.
Data points' deviations from the mean are quantified by their variance. Layman defines variance as the degree to which a set of data (numbers) deviates from the mean (average) value.

Coventry Estates sells houses.
In February they sold twice as many houses as in January.
In March they sold 10 more houses than in February.
In April they sold half as many houses as in March.
Coventry Estates sold a minimum of 123 houses from 1st January to 30th April.
Find the least number of houses sold in January.
The total number of houses sold in January by Coventry Estates are 18.
How to do the twice of number? This suggests that the amount of A is twice as large as the quantity of anything else, which in this case is B. So, if you have a dozen B items, you have twice a certain number for A, which is 24.As per the given question;
Let the total sales of the houses in January be 'x'.
In February they sold twice as many houses as in January.
February = 2x.
In March they sold 10 more houses than in February.
March = February + 10
March = 2x + 10
In April they sold half as many houses as in March.
April = March/2
April = (2x + 10)/2 = x + 5
The total sold houses = 123.
Add all the sold houses;
x + 2x + 2x + 10 + x + 5 = 123
6x + 15 = 123
On simplification;
x = 18
Thus, the total number of houses sold in January by Coventry Estates are 18.

Simplifying rational expressions entails lowering the value of a rational expression to its simplest form. A rational expression is simplified in the same way that fractions are simplified. When the numerator and denominator of a rational number have no common factor other than 1, we consider it to be its simplified version in fractions. The same method may be used to simplify rational expressions; the only difference is that polynomials are included in the fraction.

The hypotenuse of the right triangle is the diameter of the circle then the circumference of the circle is 17[tex]\pi[/tex] centimeters.
What is circumference of a circle?The midpoint is the point in the middle of a line segment in geometry. It serves as the segment and endpoint centroid because it is equidistant from both endpoints. The segment is cut in half.
The diameter of the circle is the hypotenuse of the right triangle.
Use the Pythagorean Theorem to find the diameter.
By using Pythagorean theorem we get
[tex]$$c^2 = a^2 +b^2[/tex]
substituting the values in the above equation, we get
[tex]$$c^2 = 8^2 +15^2[/tex]

[tex]$$c^2[/tex] = 289
c = 17
The diameter of the circle is 17 cm.
The circumference C of a circle is given by C = [tex]\pi[/tex] d.
Circumference of a circle = [tex]\pi[/tex]d

Find the 32 nd term of each sequence. 23,30,37,44, ...........
The 32nd term of the arithmetic sequence AP is calculated to be 240.
What basically is an AP arithmetic sequence?In mathematics, an arithmetic progression (AP) is a list and possibly sequence of numbers where each term is collected by adding a sequence towards the term before it.
The fixed number, without regard to arithmetic progression, is signified by the letter 'd.'Common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of AP: an = a + (n - 1) dThe sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l = last term of the AP.Finally, here is the answer to the question:
The following are the numbers with in displayed sequence:
23,30,37,44, ...........
The 32nd number in the series must be investigated because it contains 32 terms.
The common difference between two consecutive terms of an AP that are equal is denoted by the letter 'd.'
Let's consider the first term is'a₁' = 23.
Let's consider 'a₂' = 30 is the second term.
Let's consider the third term is 'a₃' = 37.
Substitute the values the above obtained equation; the 32nd term is-
d = a₂ - a₁
Estimate the common difference;
d = 30 - 23
d = 7
Substitute the values in the next formula; the 32nd term is
The formula given will estimate the nth term equation;
nth term of an AP: an = a + (n - 1) d
Total number of terms ; n = 32
Initial term is a = 23
Common difference d = 7
Substitute the given values in nth term formula;
a₃₂ = a + (n - 1) d
a₃₂ = 23 + (32 - 1)(7)
a₃₂ = 23 + 217
a₃₂ = 240
Thus, the 32nd term value of the given arithmetic sequence is estimated to be 240.

A farmer needs to make a 1000 -square-foot rectangular enclosure for her cows. She wants to save money by purchasing the least amount of fencing possible to enclose the area. What whole-number dimensions will require the least amount of fencing?
F. 8ft by 125ft
G. 10ft by 100 ft
H. 20ft by 50 ft
J. 25ft by 40 ft
The dimensions of the 1000-square-foot rectangular enclosure with the least amount of fencing should be 25ft by 40ft.
The amount of fencing needed can be calculated by getting the perimeter of each choice of dimensions.
Perimeter is defined as the distance that surround any two-dimensional shape. For a rectangle, the perimeter is given by the formula
P = 2l + 2w
Solving for the perimeter of each of the following choices:
F. 8ft by 125ft
P = 2l + 2w
P = 2(8) + 2(125)
P = 16 + 250
P = 266ft
G. 10ft by 100ft
P = 2l + 2w
P = 2(10) + 2(100)
P = 20 + 200
P = 220ft
H. 20ft by 50ft
P = 2l + 2w
P = 2(20) + 2(50)
P = 40 + 100
P = 140ft
J. 25ft by 40ft
P = 2l + 2w
P = 2(25) + 2(40)
P = 50 + 80
P = 130ft
The dimensions with the least perimeter will require the least amount of fencing.
Hence, a 1000 -square-foot rectangular enclosure, with dimensions 25ft by 40ft, will require the least amount of fencing.

This ensures that the lines will be parallel since two lines that are perpendicular to one another must also be parallel.
What is a perpendicular line?Two lines that meet or cross at right angles (90°) are known as perpendicular lines in geometry. The word "perpendicular" comes from the Latin "perpendicularis," which denotes a plumb line.

How to solve for the shortest length of fabric required to make the table clothGiven data
diameter of the table = 3 feet
hang down dimension = 5 inches
sew down dimension = 1 inch
width of rectangular fabric = 60 inches
The question seeks for area of the table cloth, for a circular table area of a circle = pi * r^2
required radius of cloth
= radius of the table + hang down dimension + sew down dimension
= 3 feet / 2 + 5 inches + 1 inch
