Answer:
8
Step-by-step explanation:
The number 80 is called the numerator or dividend, and the number 9 is called the denominator or divisor.
The quotient (integer division) of 80/9 equals 8; the remainder (“left over”) is 8.
80 is the dividend, and 9 is the divisor.
(X+6)+(7x+4)+(2x)=180
Answer:
x = 17
Step-by-step explanation:
x + 6 + 7x + 4 + 2x = 180 Combine like terms
10x + 10 = 180 Subtract 10 from both sides
10x = 170 Divide both sides by 10
x = 17
x = 17
Step-by-step explanation:Here are the steps to figuring out your problem:1. Add the numbers
x + 6 + 7x + 4 + 2x = 180
x + 10 + 7x + 2x = 180
2. Combine like terms
x + 10 + 7x + 2x = 180
10x + 10 = 180
3. Subtract 10 from both sides
10x + 10 = 180
10x + 10 - 10 = 180 - 10
4. Simplify
Subtract the numbers:
10x + 10 - 10 = 180 - 10
10x = 180 - 10
Subtract the numbers:
10x = 180 - 10
10x = 170
5. Divide both sides by the same factor
10x = 170
[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]
6. Simplify
Cancel terms that are in both the numerator and denominator:
[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]
x = [tex]\frac{170}{10}[/tex]
Divide the numbers:
x = [tex]\frac{170}{10}[/tex]
x = 17
Solution:
x = 17

Answer:
7.5 x 10^5
Step-by-step explanation:
See the attached worksheet.
Scientific notation is a very convenient protocol for working with, and reporting, very large or small numbers. It allows one to condense all the non-significant zeros into an expression of 10^x. Examples:
1) 0.00000000000000000015 becomes 1.5x10^-19, and
2) 45000000000000000000000 becomes 4.5x10^22
Both numbers are much easier to compare, the notation approach saves space (publishers), takes less time to type, and makes the math much easier, as this problem will demonstrate. It also eliminates many transcription errors. E.g., try dividing these two numbers using long division.
The specific problem here is to divide two very different numbers. The attached worksheet explains the steps.

What is the right-hand limit of f (x) = x/x-5 as x approaches 5?
The right-hand limit, also known as the right sided limit, is the value of a function when its input approaches a value with a small increment.The answer is + ∞
As x gets closer to 5, what is the right-hand limit of f (x) = x/x-5?The upper bound of what f(x) can be as x moves toward a from the right, denoted by lim xa+f(x)=L.
By choosing x values that are sufficiently close to a where x>a and xa, we can bring the values of f(x) as close to the limit L as we wish.
The expression for the right hand limit of f(x) is:
f = x+c / x+c-5
can be simplified with some algebraic handling:
f = 1/ x+c - 5/x+c
f = 1/1-5/ x +c

if n is a positive integer, how many integers from 0 through 2n must you pick in order to be sure of getting at least one that is odd? incorrect: your answer is incorrect. how many integers must be picked in order to be sure of getting at least one that is even?
Therefore , the we need to pick n + 2 numbers to be sure of random selection is an odd number.
What is random selection?In statistic, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. This procedure involves choosing a sample at random.
Here,
You must choose n + 2 numbers at random in order to guarantee that you will get at least one odd number.
Since n is a positive integer, the following values of n are possible:
{1, 2, 3, 4, ...}
Let's assume n = 1.
Now, in order to guarantee that you choose at least one odd integer from 0 to 2n = 2*1 = 2, how many must you choose (at random)?
There are three numbers from 0 to 2:
0, 1, 2
If you choose these at random, selecting all three digits will guarantee that you receive an odd number.
From 0 to 2*n, there are the following options if n = 2.
0, 1, 2, 3, 4
Five choices.
If you wish to choose at least one odd number for certainty after picking 3 even numbers, you must choose 4 numbers.
From 0 through 2*n, if n = 3, we get:
0, 1, 2, 3, 4, 5, 6
Since 4 of these are even, you must choose 5 of them to guarantee an odd number.
The amount of even numbers is always n + 1, therefore given a random integer n, we will have n + 1 even numbers from 0 to 2n. Therefore, if we want to be certain that we are selecting an odd number at random, we must choose n + 2 numbers.
Therefore , the we need to pick n + 2 numbers to be sure of randomly selecting an odd number.

It's employed to test the null hypothesis, which claims that "k" samples were taken from the same population or an identical population and that the median for each sample was the same or same. The null hypothesis can be expressed mathematically as S1 = S2=..... = Sk if Sj is the population median again for jth group and sample with in Kruskal-Wallis test. Naturally, the alternative theory would be that Si and Sj are not equal. This indicates that there are different pairs in at least 1 pair of groups and samples.As a result, it has been used to investigate the null hypothesis, which claims that 'k' samples were taken from populations that were either identical or similar and had medians that were similar or slightly similar.

Answer:
x > 90 > y
Step-by-step explanation:
You want to know the relationship of the central angles in a rectangle where the diagonals cross.
Angle relationsAssuming we can trust the figure (not always a good idea), we notice that x° is an obtuse angle and y° is an acute angle. (The angle opposite the longer side in this geometry will always be obtuse.)
This means ...
x° > 90°
90° > y°
The two angles form a linear pair, so their sum is 180°.
The correct description is ...
x > 90 > y

Additional comment
If the diagonals crossed at right angles, the rectangle would be a square.

how many two digit numbers can you write if you are not dont use 1 and 2
The number of permutations of two digits that we can write without 1 and 2 is 64 digits.
How to find how many two digit number s can be formed without using 1 and 2?To find how many two digit numbers can be formed if we don't use 1 and 2, we find the number of permutations.
What are permutations?Permutations are the number of ways in which n objects can be arranged in x ways. It is given by ⁿPₓ = n!/x!
Now, since we require a two digit number without 1 and 2 in any of the digits, we have 10 digits - 2 digits = 8 digits.
So, we have 8 digits to arrange in both the first digit position and second digit position.
The number of permutations for the first digit is ⁸P₁ = 8.
The number of permutations for the second digit is ⁸P₁ = 8.
So, the total number of permutations for the two digit number is N = ⁸P₁ × ⁸P₁ = 8 × 8 = 64 ways
So, the number of digits that we can write without 1 and 2 is 64 digits.
