What is Modulo ?After dividing one number by another, the modulo operation yields the remainder or signed remainder of the division.
Given:
According to the situation the equation can be
C = 5x + 11y, where x and y are non negative integers.
Now, We will fix y-values first, because there are fewer indices modulo 5:
y = 0 --> 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,... 5y
y = 1 --> 11, 16, 21, 26, 31, 36, 41, 46, 51, 56,... 5y + 11
y = 2 --> 22, 27, 32, 37, 42, 47, 52, 57, ...5y + 22
y = 3 --> 33, 38, 43, 48, 53, 58, ...5y + 33
y = 4 --> 44, 49, 54, 59, ...5y + 44
Then, 39 may be verified to be the smallest number that is impossible to obtain.
By examining each index (0, 1,..., 4), we may demonstrate this by observing that for y = 1, 6 is the largest positive integer congruent to 1 mod 5 that cannot be made, 17 is the largest positive number congruent to 2 mod 5, etc.
The largest of these improbable numbers is 39.
We could say that since 40, 41, ..., 44 are all obtainable, then we can induct by adding a multiple of 5 (i.e. if k is possible, so is k+5),
Hence, all amounts greater than 40 cents can be formed.

What are the examples I can't answer this without them
Step-by-step explanation:
So far this year, Adam has played 30 games of chess and has only won 6 of them. What is the minimum number of additional games he must play, given that he is sure to lose at least one-third of them, so that for the year he will have won more games than he lost?
A) 24
B) 57
C) 87
D) It is not possible for Adam to do this.
The correct answer is B) 57, but not sure how?
Answer:
Step-by-step explanation:Yikes. Just so we’re all clear—this is not a real SAT question.
So far, Adam’s record is 6 wins/30 games. If he plays x more games, his record will be:
image
You find the minimum x such that the fraction is greater than ½, which would mean he won more than ½ of his games.
Let’s do some math!
image
So if he plays 54 more games, and wins 2/3 of them, he’ll have the same number of wins as losses. Check on that to make sure: He’ll have played 30 + 54 = 84 games, and won 6 + (2/3)54 = 42 of them. Yep, that works.
Now here is where it gets tricky (and why this question is not SAT-caliber). Remember that he’s losing 1/3 of his games. If his 52nd, 53rd, and 54th additional games were win, win, loss, then he would have had, very briefly, a winning record after his 53rd additional game.
His 55th additional game is another chance at a winning record. If he loses that game, then he’ll win the next two, and have a winning record for sure by the 57th additional game. From there, if he continues winning 2/3 of his games, he’ll have a winning record forever.

What is the nth term for 3, 10, 29, 66 and 127?
Answer:
3, 2, 7, 14, 23.
To find the nth term of a sequence, we need to identify the pattern or rule that generates the sequence.
Looking at the given sequence 3, 10, 29, 66, 127, we can see that each term is obtained by squaring the previous term and subtracting a constant value.
Specifically, we can see that:
10 = 3^2 + 1
29 = 10^2 + 9
66 = 29^2 + 7
127 = 66^2 + 1
So the pattern seems to be that each term is obtained by squaring the previous term and adding a constant value that increases by 2 for each successive term.
To find the nth term, we can use the formula:
nth term = (n-1)^2 + c
where n is the position of the term we want to find, and c is the constant value we add to the square of the previous term.
Using this formula, we can find the nth term as follows:
For the 1st term (n=1), we have 3 as the first term.
For the 2nd term (n=2), we have:
nth term = (n-1)^2 + c
= (2-1)^2 + 1
= 1 + 1
= 2
For the 3rd term (n=3), we have:
nth term = (n-1)^2 + c
= (3-1)^2 + 3
= 4 + 3
= 7
For the 4th term (n=4), we have:
nth term = (n-1)^2 + c
= (4-1)^2 + 5
= 9 + 5
= 14
For the 5th term (n=5), we have:
nth term = (n-1)^2 + c
= (5-1)^2 + 7
= 16 + 7
= 23
Therefore, the nth term for the given sequence is:
3, 2, 7, 14, 23.
hope this helps!
Answer:
Therefore, the 6th term of the sequence is 108.
Step-by-step explanation:
To find the pattern and the nth term for the sequence 3, 10, 29, 66, 127, we can look at the differences between the terms:
7, 19, 37, 61
The second differences are constant, which suggests that the original sequence is a polynomial of degree 2 (a quadratic). To find the formula for this quadratic, we can use the method of finite differences.
The first differences are:
7, 19, 37, 61
The second differences are:
12, 18, 24
The third differences are:
6, 6
Since the third differences are constant, we can assume that the formula for the sequence is of the form an^3 + bn^2 + cn + d, where a, b, c, and d are constants.
Using the first four terms of the sequence, we can set up a system of equations:
a(1)^3 + b(1)^2 + c(1) + d = 3
a(2)^3 + b(2)^2 + c(2) + d = 10
a(3)^3 + b(3)^2 + c(3) + d = 29
a(4)^3 + b(4)^2 + c(4) + d = 66
Solving this system of equations, we get:
a = 1/2
b = 3/2
c = 5/2
d = 1
Therefore, the formula for the nth term of the sequence is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
So, the nth term for the sequence 3, 10, 29, 66, 127 is:
an^3 + bn^2 + cn + d = (1/2)n^3 + (3/2)n^2 + (5/2)n + 1
To find the 6th term of the sequence, we can substitute n=6 in the formula:
a6 = (1/2)(6)^3 + (3/2)(6)^2 + (5/2)(6) + 1
= 108
Therefore, the 6th term of the sequence is 108.

Answer:
-1-(-6) = 5
8-(-5) = 13
Step-by-step explanation:
So for the first one -1-(-6), when you have two negatives next to each other then it turns into a plus. So when it turns into a plus we will have -1+6 now although there is a plus sign we are not gonna add because our two numbers have different signs so we are gonna subtract and take the sign of our bigger number and here our bigger number is 6 so our answer will be positive and 6-1=5. So the answer is 5.
Now for the second one 8-(-5), the same thing when you have two negatives next to each other then it turns into a plus. So, when it turns into a plus we will have 8+5. And here they both have the same signs so we are gonna add and 8+5=13. So the answer is 13.
**When I say signs I mean it is either positive or negative, also a positive number if it is at the beginning of the equation then it most likely will not have the plus sign before it.**

sorry but... I HAVE AN OTHER SLOPE THINGY
there's only 2 more after this one, I promise
Step-by-step explanation:
1. we can find the slope of the line using this formula:
\(\frac{y_2-y_1}{x_2-x_1}\)
y2, y1, x2, x1 are constants from the two coordinates given, so we just plug them into the formula
\(\frac{-13-19}{-1-3}\)
now we evaluate on both ends of the fraction
\(\frac{-32}{-4}\)
simplify
\(8\)
the slope is 8
2. we are given a graph which means we can simply count the slope
the slope means:
\(\frac{rise}{run}\)
which is the change in y over the change in x , this means that we can start at a coordinate and count the slope
using this method, we get a slope of 2
3. the slope is the change in y over the change in x. the y values are decreasing by -8 while the x values are increasing by ones
this means our slope is
\(\frac{-8}{1}=-8\)
4. we just have to use the aforementioned slope formula above
\(\frac{8-(-10)}{0-9}\)
evaluate
\(\frac{18}{-9}\)
simplify
\(-2\)
the slope is -2

Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days
Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days
Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765
Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50
∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50

What is the length of bottom side of the scaled copy?
Answer:
n each scaled copy, the sides are a certain number of times as long as the corresponding sides in the original. We call this number the scale factor. The size of the scale factor affects the size of the copy. A scale factor greater than 1 makes a copy that is larger than the original.

Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
