Two consecutive odd numbers are 71 and 73 such that their sum is 144.
Continually following one another in a regular counting order or in the order of smallest to greatest are numbers known as consecutive numbers.
Let first odd number is x
then second consecutive odd number will be x+2
Given that the sum is 144
So,
x+(x+2)=144
On solving and adding like terms
2x+2=144
On subtracting 2 both sides
2x+2-2=144-2
2x=142
On dividing 2 both sides
x=142/2
x=71
Thus, two consecutive odd numbers are 71 and 73.

Bashir works in a weather station and has launched a weather ballon. The height of the baloon is 4 kilometers and it is 1 kilometer from the station. In kilometers, what is the approximate distance between the station and the balloon?
(a) 3.0
(b) 3.9
(c) 4.1
(d) 5.3
Answer:
(c) 4.1 km
Explanation:
We are given that the height of the balloon is 4 km and that it is 1 km away from the station.
Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image
where:
height of the balloon = 4 km represents one side of the triangle
distance between the base of the balloon and the station = 1 km represents the other side
distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.
To get the length of the hypotenuse, we will use the Pythagorean theorem
[tex]hypotenuse = +\sqrt{(side1)^2 + (side2)^2}[/tex]
Substitute with the givens:
[tex]hypotenuse = +\sqrt{(4)^2 + (1)^2}[/tex] = √17 ≈ 4.1 km

Determine the smallest integer value of x in the solution of the following inequality
4x+10>=11
4x+10 >= 11
4x+10-10 >= 11-10 .... subtract 10 from both sides
4x >= 1
4x/4 >= 1/4 .... divide both sides by 4
x >= 1/4
x >= 0.25
This means x must be 0.25 or larger. The next integer closest to 0.25, that is above 0.25, is the value 1.
So x = 1 is the smallest integer solution possible.

the International Space Station orbits the earth 5475 times each year write a column addition problem to find out how many times it orbits the earth in 4 years
ISS completes 21,900 orbits around the Earth in four years.
To calculate how many times the International Space Station (ISS) orbits the Earth in 4 years, we would set up a column addition problem where we add the number of orbits per year 5475 times for each of the four years. Here is the problem set up for column addition:
5475
+ 5475
+ 5475
+ 5475
------
When we add these numbers, the total will give us the number of orbits completed in four years.
The addition is as follows:
5475
+ 5475
+ 5475
+ 5475
------
21900
Therefore, the ISS completes 21,900 orbits around the Earth in four years.

So here is how it would go
-12+12 = 08+(-8) = 0-5+-5 = -10-20+20 = 0-2000+2000 = 0Is 2x/3 the same as (2/3)x ? Just wondering
the best way to understand is putting a number in place of x and seeing if they are equal to eachother so just to make it simple i'll make x=6
so your first equation is 2(6)/3 =12/3=4 now the other equation would be (2/3)6 = 6
i actually solved it putting 2 in place of x and got the same answer for both so i think they're the same

Isolate the x. Treat the less than sign as equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 47 from both sides
4x + 47 (-47) < 7 (-47)
4x < -40
Next, divide 4 from both sides
(4x)/4 < (-40)/4
x < -40/4

Which compound sentence has its solution set shown on the graph below
A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time.
“Or” indicates that, as long as either statement is true, the entire compound sentence is true.
Now as shown in the graph, the solution inequality of the graph is :
x > 3 and x < 5 [please note, circles in the graph indicate exclusion, dots indicate inclusion. in the graph given circles are shown, so it depicts exclusion]
Now let's solve each option to find if it fits in with the above inequality
Option 1 : 2x-4 > 6 or 3x < 9
⇒ x > 5 or x < 3
Option 2 : 2x - 4 < 6 and 3x > 9
⇒ x < 5 and x > 3
Option 3 : 3x + 8 > -7 or -4x < 12
⇒ 3x > -15 or x < -3
⇒ x > -5 or x < -3
Option 4 : 3x + 8 < -7 and -4x > 12
⇒ 3x < -15 and x > -3
⇒ x < -5 and x > -3
So the compound sentence in option 2 : 2x - 4 < 6 and 3x > 9

Find the area of an equilateral triangle (regular 3-gon) with the given measurement. 9-inch perimeter A = sq. in.
Aswer: 9 / 4 sqrt 3
Solution:
Perimeter: P=9 inch
Area: A=?
A=(1/4) sqrt(3) L^2
Side of the triangle: L
We need the side "L" of the triangle:
We know: P=3 L
Replacing the perimeter in the equation above:
9 inch=3 L
Solving for L: Dividing both sides of the equation above by 3:
(9 inch) / 3 = 3 L /3
3 inch = L
L = 3 inch
Replacing L=3 inch in the formula of Area:
A=(1/4) sqrt(3) L^2
A=(1/4) sqrt(3) (3 inch)^2
Squaring:
A=(1/4) sqrt(3) (9 inch^2)
Multiplying:
A=(1*9)/4 sqrt(3) inch^2
A=9/4 sqrt(3) inch^2
Answer:
9√3/4
or
9/4√3
Step-by-step explanation:
P=3a=9⇒a=3 inches.
The area of the equialteral triangle is
A=\dfrac{a^2\sqrt{3}}{4}=\dfrac{3^2\sqrt{3}}{4}=\dfrac{9\sqrt{3}}{4}\ \text{sq. in}.A=4a23=4323=493 sq. in.

a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4x y).
So, 22 is your coefficient.
In the mathematical expression 22x + 54.35, the coefficient is 22. It describes how much the teacher spends in dollars each time she restocks her classroom supplies. The constant term '54.35' represents the initial spending at the start of the school year.
Explanation:In the given expression 22x + 54.35, the coefficient is 22.
The coefficient, in this context, represents the cost (in dollars) that the teacher spends each time she restocks her classroom supplies. Every time the teacher purchases more supplies during the school year, she is spending $22, hence the '22' is multiply by 'x' which indicates the number of times these supplies are restocked.
The constant term '54.35', on the other hand, represents the initial amount the teacher spends at the start of the school year. To summarise, '22x' describes the total expense on supplies restocked during the year, and '54.35' is the initial expenditure.

What kind of triangle would the measurements 7ft 15ft 17ft
Answer:
This is an Obtuse triangle.
Step-by-step explanation:
A Equilateral Triangle is a triangle where all sides are equal. Here all sides are different so it is not an Equilateral Triangle.
Isosceles triangle is a triangle that has 2 sides that are equal. Here all sides are different therefore this is not an Isosceles triangle.
A right angled triangle is a triangle whose sides satisfy the following equality.
Lets say A triangle has sides a, b and c. Where c is the highest value.
Then, [tex]a^{2} +b^{2} =c^{2}[/tex]
Lets substitute the values to the above equation to see whether it the triangle we are given satisfies the above equality,
[tex]7^{2} +15^{2}[/tex] = [tex]49+225[/tex]=[tex]274[/tex]
[tex]17^{2} =289[/tex]
Therefore, [tex]7^{2} +15^{2}[/tex] ≠[tex]17^{2}
So it is not a Right Angled Triangle.
If the sum of squares of the shorter sides is greater than the square of the longer side then it is an Acute angle if not it is an obtuse angle.
[tex]7^{2} +15^{2}[/tex] = [tex]274[/tex]≤[tex]17^{2} =289[/tex]

the difference of two numbers is 28 find both numbers if the larger is four more than three times the smaller
Let x = the smaller number.
Let 4+3x = the larger number.
So, 28 = 4+3x - x
24 = 2x
x = 12.
The smaller number is 12, now we need to find the larger number,
4+3(12)
40
So, the numbers are 12 and 40.
The equation can be solved by setting up two equations based on the information given, and then substitifying and simplifying the equations to solve for the two numbers. The two numbers are 12 and 40.
Explanation:
The subject of this question is dealing with equations in mathematics. To problem-solve this, we can first form an equation based on the information given: The larger number is equal to 'four more than three times the smaller number' and 'the difference between the two numbers is 28'.
So we can set up two equations:
Larger Number (L) = 3* Smaller Number (S) + 4 Larger Number (L) - Smaller Number (S) = 28By substituting the first equation into the second, it resolves as:
3S + 4 - S = 28
which simplifies to:
2S = 24
So, the smaller number S = 24/2 = 12. Substituting S = 12 into the first equation gives:
L = 3*12 + 4 = 36 + 4 = 40
So the two numbers are 12 and 40.
