Answer:
factor: a submultiple; an integer value that gives an integer quotient when the number is divided by it.multiple: the product of the number and another integerStep-by-step explanation:
FactorsA set of factors of a number (N) is a set of integers {f1, f2, f3, ...} whose product is the number:
f1 × f2 × f3 × ... = N
Often the term "factors" is used to mean "prime factors," the set of prime numbers whose product is N.
When N = 25, the prime factors are {5, 5}. That is ...
5×5 = 25
__
DivisorsA "divisor" of a number is a sub-multiple of N. That is, the quotient N/k is an integer for some divisor k of N. Usually, we're interested in integer divisors. All prime factors will be integer divisors of N. The term "factor" is often used when the term "divisor" is meant.
Divisors of N = 25 include 1, 5, and 25. There will be an odd number of integer divisors (as here) if the number N is a perfect square.
__
MultiplesFor an integer k, the value k×N is called a multiple of N, often, the k-th multiple of N.
Multiples of 25 include 25, 50, 75, 100, 125, and any other decimal number ending in 25, 50, 75, or 00.
__
Another example
When N=30, the prime factors are {2, 3, 5}. The divisors are {1, 2, 3, 5, 6, 10, 15, 30}. (Note there are an even number of divisors.) Multiples of 30 include 30, 60, 90, 120, ....

A card is drawn from a well-shuffled deck of 52 cards. What is the probability of drawing an ace or a 6?
A. 13/2
B. 7/26
C. 2/13
D. 6/52
Answer:
C
Step-by-step explanation:
There are 4 aces and 4 sixes. 4 + 4 is 8 (since it says or) so the chance is 8 / 52. 8 / 52 simplified, divide both sides by 4 and you get 2 / 13.
Answer:
C
Step-by-step explanation:
there are 4 aces and 4 sixes in a deck of 52 cards.
"And" means a probability * another probability
"Or" means a probability + another probability.
In this case, it is (probability of picking an ace) + (probability of picking an six).
[tex]\frac{4}{54} + \frac{4}{54} = \frac{8}{54} = \frac{2}{13}[/tex]

Answer:
y - 2 = 6 (x - 1)
Step-by-step explanation:
Slope intercept form equations look like this:
y - y1 = m (x - x1)
***m = [tex]\frac{y2-y1}{x2-x1}[/tex]
Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:
y - 2 = m (x - 1)
To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.
[tex]\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6[/tex]
Now that we know m = 6, let's plug that back into the original equation to get our final answer:
y - 2 = 6 (x - 1)

Answer:
y: 13, 22, 25, 28
ordered pairs: (3, 13) (6, 22) (7, 25) (8, 28)
Step-by-step explanation:
Given:
function: y = 3x + 4values of x: -3, 6, 7, 8To find the y-values, substitute the x-values into the function and solve.
when x = 3
y = 3(3) + 4

when x = 6
y = 3(6) + 4
= 18 + 4
= 22
when x = 7
y = 3(7) + 4
= 21 + 4
= 25
when x = 8
y = 3(8) + 4
= 24 + 4
= 28
Therefore, the ordered pairs are; (3, 13) (6, 22) (7, 25) (8, 28)

melanie and patrick have different phone services. the relationship of the monthly cost, y dollars, to send or receive x text messages, is a linear function. the cost of patricks texting is described by y = 0.03x + 5. the cost of melanies texting is shown in the table
Answer:
Melanie: y = 0.25x
Patrick: y = 0.03x + 5
Patrick's service is cheaper when 50 texts are sent or received in one month.
Step-by-step explanation:
Let's find out Melanie's monthly texting cost function using the table. We are given multiple points that the line describing her monthly text costs passes through, so we can use the slope formula to calculate the slope of this line first.
m = (y2 - y1) / (x2 - x1)Substitute (5, 1.25) and (10, 2.50) into this formula.
m = (2.5 - 1.25) / (10 - 5)m = 1.25 / 5 m = 0.25Now we can use the point-slope equation to determine the line that describes Melanie's monthly texting cost.
I'm going to use the point (5, 1.25) and the slope m = 0.25.
y - y1 = m(x - x1)y - 1.25 = 0.25(x - 5)y - 1.25 = 0.25x - 1.25 y = 0.25xWe have Melanie's function:
y = 0.25xWe have Patrick's function:
y = 0.03x + 5
We want to determine which service is cheaper when 50 texts are sent/received in one month.
The number of texts sent and received is represented with the variable "x", and the cost of this service is represented with the variable "y".
All we need to do is substitute 50 for x in both equations to see if Melanie or Patrick's service is cheaper.
Starting with Melanie:
y = 0.25x y = 0.25(50)y = 12.50Now with Patrick:
y = 0.03x + 5 y = 0.03(50) + 5y = 1.5 + 5 y = 6.5Patrick's service is substantially cheaper than Melanie's service when 50 texts are sent or received in one month.

They kept adding sand, and ten minutes later the volume of the sand cone had increased by 30%. What is the approximate volume of the sand cone now? Label your answers with the correct units. (Show your work) Use 3.14 to approximate pi
Answer:
volume = 527.52 in³
volume increased by 30% = 685.776 in³
Step-by-step explanation:
Volume of a cone
[tex]V=\dfrac13\pi r^2h[/tex]
(where r is the radius and h is the height)
Given:
diameter = 12 in ⇒ radius = 6 inheight = 14 in[tex]\pi =3.14[/tex][tex]\implies V=\dfrac13 \cdot 3.14 \cdot 6^2 \cdot 14[/tex]
[tex]\implies V=527.52 \ \sf in^3[/tex]
---------------------------------------------------------------------------
If the volume increases by 30% then it will now be 130% of the original volume.
130% as a decimal = 130/100 = 1.3
Therefore, to find the new volume, multiply the original volume by 1.3.
[tex]\implies V=527.52 \cdot 1.3[/tex]

Explanation:
R = D + 12 (1)
D = B + 6 (2)
R = 2*B (3)
Put (3) into (1): 2*B = D + 12 (4)
Rewrite (2) as B = D - 6 and put this into (4): 2*(D - 6) = D + 12
So: 2D - 12 = D + 12
Subtract D from both sides and add 12 to both sides to get: D = 24

A factory makes light fixtures with right regular hexagonal prisms where the edge of a hexagonal base measures 4 cm and the lengths of the prisms vary. It cost $0.04 per square centimeter to fabricate the prisms and the factory owner has set a limit of $11 per prism. What is the maximum length of each prism?
The maximum length of the prism is highest length of the hexagonal prism
The maximum length of each prism is 8.0 cm
How to determine the maximum length of each prism?The surface area of the hexagonal prism is calculated using:
A = 6al + 3[tex]\sqrt[/tex]3 a^2
Where:
a represents the edge length; a = 4 cm
l represents the length (or height) of the prism
The surface area costs $0.04 per square centimeter.
So, we have:
C = 0.04 * [6al + 3[tex]\sqrt[/tex]3 a^2]
The maximum cost is $11.
So, the equation becomes
11 = 0.04 * [6al + 3[tex]\sqrt[/tex]3 a^2]
Substitute 4 for a
11 = 0.04 * [6 * 4l + 3[tex]\sqrt[/tex]3 * 4^2]
Evaluate the products and exponents
11 = 0.04 * [24l + 48[tex]\sqrt[/tex]3]
Divide both sides by 0.04
275 = 24l + 48[tex]\sqrt[/tex]3
Subtract 48[tex]\sqrt[/tex]3 from both sides
24l = 275 - 48[tex]\sqrt[/tex]3
Evaluate the difference
24l = 191.9
Divide both sides by 24
l = 8.0
Hence, the maximum length of each prism is 8.0 cm

whats the process for solving n?
Answer:
Step-by-step explanation:
3^(n-1) * (n(n+1)/2 = 20412
The n(n +1)/2 is a factorial which is defined for integers so we are looking for a whole number solution.
We could draw a graph manually or using software and get the solution where the graph cuts the x axis.
Also we could find the prime factors of 20412:
20412 = 2^2 * 3^6 * 7
and try substituting 2, 3 and 7 into the equation
Using this method we see that one solution is n = 7.
I could have tried n = 7 first because 3^n-1 = 3^6!!

How to Calculate the Fraction of a Whole Number
How to Calculate the Fraction of a Whole Number
You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
15
1
So now that we've converted 15 into a fraction, to work out the answer, we put the fraction 2/5 side by side with our new fraction, 15/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
2 x 15
5 x 1
=
30
5
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 30 and 5 is 5.
We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.
30/5 = 6
5/5 = 1
When we put that together, we can see that our complete answer is:
6
1
The complete and simplified answer to the question what is 2/5 of 15 is:
6
