Answer: 4,5,6,7,8
Step-by-step explanation:
Let the first integer be A; then the five consecutive integers are A, A+1, A+2, A+3, and A+4.
If the sum of the first three equals the sum of the last two, then A + (A+1) + (A+2) = (A+3) + (A+4)
Combining, 3A + 3 = 2A + 7 … A =4
The five Integers are thus 4, 5, 6, 7, and 8

about 310 000 t of atlantic cod were caught in 1991. in 2001 the mass of the cod caught was 87% less. HOw much cod was caught in 2001
Number of Atlantic cods caught in the year 2001 is; 40300 t
How to solve percentage word problems?Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. This is expressed as;
Percentage = (value / total value) * 100%
Now, we are told that;
Number of Atlantic cods caught in 1991 = 310000 t
We are told that in the year 2001, there were 87% less caught. Thus;
Number by which it was reduced = 310000 * 87% = 269700
Thus;
Number of Atlantic cods caught in the year 2001 = 310000 - 269700
Number of Atlantic cods caught in the year 2001 = 40300 t

(3s+2f=18)
(2s+3f=15.75)
Answer:
(s, f) = (4.5, 2.25)
Step-by-step explanation:
You want the solution to the simultaneous equations ...
3s+2f = 182s+3f = 15.75SolutionWriting these in general form, we have ...
3s +2f -18 = 0
2s +3f -15.75 = 0
Using the "cross-multiplication method" for solution, we find ...
∆1 = (3)(3) -(2)(2) = 5
∆2 = (2)(-15.75) -(3)(-18) = 22.5
∆3 = (-18)(2) -(-15.75)(3) = 11.25
s = ∆2/∆1 = 22.5/5 = 4.5
f = ∆3/∆1 = 11.25/5 = 2.25

Equation represents the population of the city 'p' in thousand of people in x years when in 2005 projected population is 450,000 and increases by 4,000 people each year is given by p = 4x + 450.
Total population in 2010 is equal to 470,000 people.
As given in the question,
Let 'p' represent the population in thousands of people.
Let x represents the number of years.
Population projected in 2005 = 450,000 people
= 450 ( in thousand people)
Population increases by 4000 people each year that is equal to 4 (in thousand of people)
Required equation to represent the population in x years ( in thousand of people ) is given by:
p = 4x + 450
Population in 2010 is equal to :
p = 4 ( 2010 - 2005) + 450
= 4(5) + 450
= 20 + 450
= 470 ( in thousand of people)

2. Answer.
The 7 cancels out so we are left with k = 13 since

A triangle has a perimeter of 7x + 8. The first side of the triangle has a length of 3x, and the second side has a length of 2x − 5. What is the length of the third side of the triangle?
x + 13
2x + 13
5x − 5
12x + 3
The length of the third side of the triangle is 2x+13.
According to the question,
We have the following information:
A triangle has a perimeter of 7x + 8. The first side of the triangle has a length of 3x, and the second side has a length of 2x − 5.
We know that perimeter of triangle is the sum of all three sides of triangle.
Let's take its third side to be y.
So, we have the following expression:
3x+2x-5+y = 7x+8
5x-5+y = 7x+8
Adding 5 on both the sides:
5x+y = 7x+8+5
5x+y = 7x+13
Subtracting 5x from both the sides:
y = 7x-5x+13
y = 2x+13
Hence, the correct option is B.

The correct statement is that the value of n that make the relationship a function are any value except 1, 3, or 2
What is a function in mathematics?A function is a relationship that maps the elements of a set A to the elements of a set B, such that each element of A is mapped to exactly one element of the set B.
The ordered pair of known values are a function as the elements of the input variable are all different and the element of the output variable are also different, which indicates a 1 to 1 relationship.
The known elements of the set A in the question are; 2, 6, and 4
The elements of the set A are known as the domain of the function.
The known element of the set B are 8, 0, and 2
The fourth ordered pair (2·n, n), has a value similar to the pair (4, 2)
To prevent the presence of the elements 2,. 6, and 4, being assigned to other elements apart from 8, 0, and 2, the value of 2·n can be any value except 2, 6, 4
Therefore;
n can be any value except 2/2 = 1, 6/2 = 3, or 4/2 = 2

If ( x , y ) represents the location of any point on the original square, which ordered pair represents the coordinates of the corresponding point on the resulting square?
If (x, y) represents the location of any point on the original square, the ordered pair which represents the coordinates of the corresponding point on the resulting square is: (0.4x, 0.4y).
What is dilation?In Geometry, dilation simply refers to a type of transformation which changes the size of a geometric object and the location of its points based on the scale factor, but not its shape.
What is scale factor?In Geometry, a scale factor can be defined as the ratio of two corresponding side lengths or diameter in two similar geometric objects (shapes) such as equilateral triangles, square, quadrilaterals, polygons, etc., which can be used to either enlarge or reduce their size.
Generally speaking, the transformation rule for the dilation of a geometric object (square) based on a specific scale factor is given by this mathematical expression:

There are 100 items in a garage sale. 30% of the items are sold during the first hour of the sale. If 10 items are sold during the second hour, what percent of the items have not been sold?
The percentage of items that have not been sold is: 60%
In mathematics, the percentage is calculated by dividing the given value by the total which is then multiplied by 100.
Percent in itself stands for out of 100.
Let the total number of items= i
Let the percentage be represented as= p
Then,
i=100 (Given in the question)
Let the number of items sold in the first hour be= a
Let the number of items sold in the second-hour be= b
Since,
p= Given Value/Total value x100
thus,
a/100x100=30%
The hundreds cancel out.
Thus, a=30 -(i)
The number of items sold in the second hour= b
b=10 (provided in the question) -(ii)
Let the total number of items sold be=T
The total number of items sold= a+b
From (i) and (ii)
Total number of items sold=30+10
Thus,
Total number of items sold=40 -(iii)
Number of items that have not been sold(n)=100-(a+b)
=100-T
= 100-40
From (iii)
n = 60 -(iv)
Then,
Percentage of items that have not been sold = n/100x100
From -(iv)
= 60/100x100
Canceling hundred by hundred
= 60%
Thus,
Answer: The percentage of items that have not been sold is: 60%

According to the Pythagoras theorem, the value of x is 13.76
Pythagoras theorem:
“In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“ is known as Pythagoras theorem.
Given,
Here we have the triangle with the side values.
Now, we have to find the value of x through this given values.
In order to calculate the value of x,
First, we need the value of the side KM.
Let us consider the value of KM is y.
Then according to the concept of Pythagoras theorem,
The value of y is calculated as,
=> (12.3)² = y² + (5.4)²
=> 151.29 = y² + 29.16
=> y² = 122.13
=> y = 11.05
Therefore, the value of the hypotenuse x is calculated as,
=> x² = (11.05)² + (8.2)²
=> x² = 122.13 + 67.24
=> x² = 189.37
=> x = 13.76
Therefore, the value of x is 13.76.

To write an equation that represents the cost of a pizza.
An equation that represents the cost of a pizza will be
C = 9 + 1.75x + 0.50y
Fixed cost = $9
Cost of additional inch = 1.75x
Cost of additional topping = 0.50y
Total cost (C) will then be:
= 9 + (1.75 × x) + (0.50 × y)
C = 9 + 1.75x + 0.50y

Triangle:
The polygon with three edges known as sides and three vertices are known as triangle.
Given,
Here we have the triangle with their corresponding angle.
Now, we have to order the sides from shortest to longest.
Here in the given triangle we know the angles of m∠D = 61, m∠E = 60, and m∠F = 59.
By knowing this measures we can order the sides from shortest to longest, because angles are the opening between to sides, which means if the angle is wide, its opposite side that is in front of the angle is wide too, if the angle is narrow, its opposite side will be narrow.
In this case, the opposite side of ∠D will be the longest, because it is the largest angle. And the opposite side of m∠E will be the second longest, and finally the opposite side of ∠F will be the smallest.
From values, the shortest to longest the order is written as DE, DF and EF.
