When an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33. Find the value of the greater integer.
Answers
The two consecutive odd integers are -7 and -5, then the greater integer is -5.
How to find the value of the largest integer?Let's say that the smaller integer is x and the larger one is y.
Such that if both of these are odd and consecutive, then y = 2 + x.
We can now write:
8*y - x = -33
Replacing y by x + 2 we get:
8*(x + 2) - x = -33
8x + 16 - x = -33
7x = -33 - 16 = -49
x = -49/7 = -7
that is the smaller integer, then the next one is:
y = x + 2 = -7 + 2 = -5

The required value of the greater integer among the two consecutive odd integers is - 5.
What is an integer?An integer is a real number that has no decimal part.
suppose we have specified a particular odd no. 'O' then the consecutive odd integers are those numbers that arrive after every two numbers.
Given, an integer is subtracted from 8 times the next consecutive odd integer, the difference is -33.
Assuming the first odd integer to be 'n'.
So, the next consecutive odd integers are (n + 2), (n + 4)...
∴ 8(n + 2) - n = - 33.
8n + 16 - n = - 33.
7n = - 33 - 16.
7n = - 49.
n = - 49/7.
n = - 7.
So, the two integers are -7 and (-7 + 2) = - 5.

Answers
The greatest integer in the system has a value of 5
How to calculate the value of the greater integer?From the question, the given parameters are:
The sum of an integer and 4 times the next consecutive odd integer is 23
Let the integer be x
So, we have the following representation
The sum of x and 4 times the (x + 2) is 23
This means that
Integer = xNext odd integer = x + 2So, we have
x + 4(x + 2) = 23
Open brackets
x + 4x + 8 = 23
Evaluate the like terms
5x = 15
Divide by 5
x = 3
So, we have
Next odd integer = 3 + 2
Evaluate
Next odd integer = 5
Hence, the value of the greatest integer is 5

Find the approximate perimeter of the isosceles triangleAOPD. Round your answer to the whole number.
Answers
The perimeter of the given triangle is the sum of the following segments:
Perimeter = PD + DO + OP
based on the given graph, you have that the coordinates of the points PDO are:
P: (1,-6)
D: (4,3)
O: (7,-6)
use the following formula for the distance in between two points:
d = √((x2 - x1)²+(y2 -y1)²)
where (x1,y1) and (x2,y2) are two points on the cordinate system.
For segement PD you have:
PD = √((1-4)²+(-6-3)²) = √(100) = 10
For segemtn DO:
DO = √((4-7)²+(-6-3)²) = √(100) = 10
For segment OP:
OP = √((1-7)²+(-6+6)²) = √36 = 6
then, the perimeter of the triangle is:
perimeter = 10 + 10 + 6 = 26

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
given that :
Salesman A gets paid $300 a month plus $8 for every sale he makes :
let the no. of sales A made be : x
then, in order to make the same amount of salesman b we equate btoth the amount :
300 + 8x = 1500
8x = 1500-300
8x = 1200
x = 1200/8
x = 150
Therefore, the number of sales by A must be 150 to make the same amount of salesman b.

The perimeter of a square can be found using p=n+n+n+n
Answers
Answer: Well, yes. It's more like p = s + s + s + s. "S" = side. "P" = perimeter.
So, this is theoretically true if your variable for a side just happened to be "n".
You also put, "The perimeter of a square", A simpler way to put this is
P = s4 or in your case P = n4.
Because this shape is a square all side lengths and angles will be congruent, and therefore will all be the same (which is why we are able to multiply one side by four.)

What is termed as the markup percentage rate?The markup percentage is the difference between how an item costs this same seller and what the customer pays. The greater the markup, as a percentage of a cost, the greater the profit.The markup percentage of a product is the ratio of its gross profit to its cost.It is most useful for companies that sell physical goods in industries in which prices are linked to the cost of acquiring more.The percentage of markup varies by industry as well as product. Other than discovering a price that did work for both your company and your customers, there is no golden rule.For the given question.
The cost of the item is $103.
The customer pays is $515.
The mark up percentage is -
mark up percentage = 515 - 103 / 103
mark up percentage = 4 × 100%
mark up percentage = 400 %.

The proper test statistic has a value of 13.21.
As a result, repeated measurements of cholesterol levels from the same blood sample are taken to assess a lab technician's consistency.
The desired accuracy is a measurement variance of 2.78 or less. In the event that the lab technician conducts 16 measurements, and the sample's measurement variance is 2.45.
1) n=16 samples were used.
The desired accuracy is a measurement variance of 2.78 or less.

Step-by-step explanation:
Hello!
Slope-Intercept Form: y = mx + b
m = slopeb = y-interceptThe y-intercept of the graph, or the point where the graph intersects the y-axis, is 7.
We can find the slope by finding the Rise/Run.
The graph rises negatively by 3 units as it runs positively by 1 unit, so the slope is -3/1 or -3.
Given the slope and y-intercept, the equation of the line is y = -3x + 7.

a 13-ft ladder rests against a vertical wall. if the bottom of the ladder slides away at 1 ft/s, at what rate is the top of the ladder sliding down the wall when the bottom of the ladder is 5 ft from the wall? g
Answers
The given situation can be solved using the differential equation and the top of the ladder slides downward at 0.417 ft/s.
Let:
x be the distance from the bottom of the ladder to the base of the wall
y be the distance from the top of the ladder to the bottom of the wall
When the ladder is still, apply the Pythagorean Theorem,
x² + y² = 13²
5² + y² = 13²
y² = 169 - 25 = 144
y = 12 ft
When the ladder slides, apply the differential equation:
x² + y² = 13²
2x . dx/dt + 2y . dy/dt = 0
Substitute x = 5, dx/dt = 1, y = 12
2 . 5 . 1 + 2 . 12 . dy/dt = 0
24 dy/dt = -10
dy/dt = -5/12 = - 0.417 ft/s
The minus sign indicates that the ladder is sliding downward.
