The sum of 3 consecutive odd integers is 33. Find the integers (n).
The integer(n) in the odd integers is 9.
How to find variables in equation?The sum of 3 consecutive odd integers is 33.
Odd integers are defined as any integers which cannot be divided by two. Therefore, odd integers includes 1, 3, 5, 7, 9, 11, 13 etc
Therefore, the integers can be found as follows:
let
n = first odd integer
n + n + 2 + n + 4 = 33
combine like terms
n + n + n + 2 + 4 = 33
3n + 6 = 33
subtract 6 from both sides of the equation
3n + 6 - 6 = 33 - 6
3n = 27
divide both sides by 3
n = 27 / 3
Therefore,
n = 9

The rise and span for a roof is the ratio of the rise to the half-span. If the rise is 8 feet and the span is 30 feet,what is the pitch in simplest form?
Answer:
8 feet to 15 feet or [tex]\dfrac{8}{15}[/tex].
Step-by-step explanation:
We know that pitch is is the ratio of the rise to the half-span.
It is given that, the rise is 8 feet and the span is 30 feet.
[tex]\text{Half of span}=\dfrac{30}{2}=15[/tex]
We need to find the pitch in simplest form.
[tex]Pitch=\dfrac{\text{Rise}}{\text{Half-span}}[/tex]
[tex]Pitch=\dfrac{8}{15}[/tex]
Therefore, the pitch in simplest form is 8 feet to 15 feet or [tex]\dfrac{8}{15}[/tex].

Salesman Randy gets a fixed salary of $2000 per month and a commission of 2% on sale. If total sale is $30,000 for the month, find his total salary for the month?
Answer:
$2600
Step-by-step explanation:
If his monthly salary is $2000 and 2% commission.
He made $30,000 in sales for the month so lets make an equation.
s = total salary
s = $2,000 + .02($30,000)
s = $2,000 + $600
s = $2600
Randy's salary for the month is $2600.
Geometry ∠1 and ∠2 are vertical angles. If m∠1 = 17x + 1 and m∠2 = 20x – 14, find m∠2.
Answer:
m∠2= 86
Step-by-step explanation:
since they are vertical angles, that means they are both equal to eachother.
so lets set them equal!
17x+1=20x-14
17x+15=20x
15=3x
x=5
now input x into m∠2
m∠2 = 20(5) – 14 = 86

Simplify your answer and write it as a proper fraction, mixed number, or integer.
Submit
Answer:
EF = 8
Step-by-step explanation:
The following data were obtained from the question:
EF = 2x
FG = 8
EG = 4x
EF =?
To obtain the value of EF, we shall first, obtain the value of x. This can be obtained as follow:
EG = EF + FG
EF = 2x
FG = 8
EG = 4x
4x = 2x + 8
Collect like terms
4x – 2x = 8
2x = 8
Divide both side by 2
x = 8/2
x = 4
Therefore, the value of x is 4.
Finally, we shall determine the the value of EF as follow:
EF = 2x
x = 4
EF = 2x
EF = 2(4)
EF = 8
**** Check ****
EG = EF + FG
EF = 2x
EG = 4x
FG = 8
4x = 2x + 8
x = 4
4(4) = 2(4) + 8

The perimeter of a rectangle is 60 meters. Its length is 10 meters. What is its width?
Answer:
[tex]\boxed {\tt 20 \ meters}[/tex]
Step-by-step explanation:
The perimeter of a rectangle can be found using the following formula.
[tex]p= 2l+2w[/tex]
We know the perimeter is 60 meters and the length is 10 meters.
[tex]p=60 \ m[/tex]
[tex]l= 10 \ m[/tex]
Substitute the values into the formula.
[tex]60 \ m = 2(10 \ m) + 2w[/tex]
Multiply 2 and 10.
[tex]60 \ m = 20 \ m +2w[/tex]
Subtract 20 from both sides of the equation.
[tex]60 \ m - 20 \ m = 20 \ m - 20 \ m +2w[/tex]
[tex]60 \ m - 20 \ m =2w[/tex]
[tex]40 \ m = 2w[/tex]
Divide both sides of the equation by 2.
[tex]\frac{40 \ m}{2} =\frac{2w}{2}[/tex]
[tex]\frac{40 \ m}{2} =w[/tex]
[tex]20 \ m =w[/tex]
The width of the rectangle is 20 meters.
A ballroom has a square dance floor. The area of the floor is 400 square feet.
If the length of each side of the square increased by one foot, would its area be a rational number?
Choose all that apply.
Answers:
A. - The area of the floor would be a rational number.
B. - The area of the floor would be an irrational number.
C. - Each side length would be a perfect square.
D. - The area of the floor would be a perfect square.
E. - The area of the floor would be a nonterminating, nonrepeating decimal.
Answer:
D
Step-by-step explanation:
Area of square=400sq.ft
or,l²=400sq.ft
or,l=(400sq.ft)½
or,l=(20²sq.ft)½
or,l=20ft
Thus,length of square is 20ft.
If length of square is increased by 1 ft then ,
New length=(20+1)ft=21ft
Area of square=(21ft)²
=441sq.ft

How do I solve it ? I don’t understand
Answer:
1) 3 Points Include: E, B and F. To explain in Detail. Point E, which is (-1,1) Point B, which is (0,-2) and Point F, which is (2,3) The Directions tell you to name 3 Points on the image. The points I just explained are all on the graph, so they are all points in the Image.
Two Lines are: Lines CD and Lines AB. These are both lines on the images. The points A and B are connected with a line, so they are a line on the graph. The Points C and D are also connected by a line, therefore, both lines CD and AB are lines on the image.
A Line Segment: A line segment is a line connected with two end points, You can say a line is a segment when both ends of the line have a dot, also known as a point. One line segment in this image is Line EB, both the points are connected by a line, and both sides of the line have a point.
The Plane: The plane is the entire surface that everything is on. The plane has all the lines, segments, and points. All planes extend infinitely far. We can see, the plane is "O". The letter O is located towards the middle of the graph, Therefore, the Plane is "O"
2)One Point: On the Plane, one point is point S. Q and R are also points, but the question only asks for one point.
The Line: There is only one line on the plane, this line is line QR. Both points Q and R are connected by a line.
The Plane: The Plane is "T" in the bottom left of the image, in the corner of the plane (the plane is the blue area) you can see the letter T. "T" is the plane.
Does the line go through the Plane? Yes. The line does go through the plane. Here's why: On the line QR, both sides of the line have arrows. If a line has arrows that means the line goes on forever in the direction the arrow is pointing. If a line has two dots, its a segment, which means the lines end at the points, they do not go on forever. In this case, the line goes on forever and it goes through the blue area, which is the plane.
