Answer:
A rectangle is defined by its length = L, and its width = W.
So the perimeter of the of the rectangle can be written as:
Perimeter = 2*L + 2*W.
In this case, we want to leave the perimeter fixed, so we have:
24ft = 2*L + 2*W.
Now, we do not have any other restrictions, so to know the different dimensions now we can write this as a function, by isolating one of the variables.
2*L = 24ft - 2*W
L = 12ft - W.
or:
L(W) = 12ft - W.
Such that:
W must be greater than zero (because we can not have negative or zero width).
And W must be smaller than 12ft (because in that case we would have zero or negative length)
Then the possible different dimensions are given by:
L(W) = 12ft - W
0ft < W < 12ft.
Is part A correct? Im not entirely sure about it and also what is part B???
Answer:
A) [tex]\frac{n^2}{2} + \frac{n}{2}[/tex]
B) 78
Step-by-step explanation:
B) To find the sum of first 'n' whole numbers , formula used is :-
[tex]\frac{1}{2} ( n^2 + n)[/tex]
We have to find the sum of first 12 whole numbers . So here n = 12
Putting the value of 'n' in above formula ,
[tex]\frac{1}{2} ( 12^2 + 12) \\\\=> \frac{1}{2} ( 144 + 12)\\\\=> \frac{156}{2} = 78[/tex]
Answer:
see explanation
Step-by-step explanation:
A
Given
[tex]S_{n}[/tex] = [tex]\frac{1}{2}[/tex](n² + n) ← multiply each term in the parenthesis by [tex]\frac{1}{2}[/tex]
= [tex]\frac{1}{2}[/tex] n² + [tex]\frac{1}{2}[/tex] n
B
To find the sum of the first 12 whole numbers, substitute n = 12 into the formula, that is
[tex]S_{12}[/tex] = [tex]\frac{1}{2}[/tex] (12² + 12) = [tex]\frac{1}{2}[/tex] (144 + 12) = [tex]\frac{1}{2}[/tex] × 156 = 78

A point lies on AB¯¯¯¯¯ and is 2/5 the distance from A to B. Point A is located at (2, 6) and point B is located at (18, 12). What are the coordinates of this point?
We know, point on a line segment which cut a line into the ratio m : n is given by :
[tex][(\dfrac{mx_1+nx_2}{m+n}),(\dfrac{my_1+ny_2}{m+n}) ][/tex]
Putting value of point A and B and m =2 and n = 5 .
We get :
[tex][(\dfrac{2(2)+5(18)}{2+5}),(\dfrac{2(6)+5(12)}{2+5}) ]\\\\(\dfrac{94}{7},\dfrac{72}{7})[/tex]
Hence, this is the required solution.

Step-by-step explanation:
Consider the population of florida , the area of colorado, and the flight time from philadelphia to san francisco, which of these has a value that varies.
Answer:
the population of Florida
Step-by-step explanation:
A value that varies means a value that shall change over a period of time.
Accordingly when we talk about population the population shall increase or decrease with time, as this the natural thing that new babies are born and at the same time people also die.
Even in Florida there will be new babies who are born and also there shall be people who might be dying. Accordingly the population count keeps on changing.
The flight time depends upon the aerial distance and the speed which generally remains same.
Accordingly if a flight takes hours to travel the distance it will be same.
The area of a particular place shall not change as earth will not create new land, or the area will remain same by any how only exception to this is acquisition of land of neighbouring places, by war or political influence, but not in a natural manner.
Thus, population of Florida is variable.
Find the value of c: 4(c-6)/c-7 = 9/2

8c-9c=9c-15-9c
\frac{-c}{-1}=\frac{-15}{-1}
c=15
Which number line shows the solution to the inequality −2(3x − 1) < 8?
Answer:
x∈ (-1, ∞)
Step-by-step explanation:
Solution of the inequality:
−2(3x − 1) < 8 ⇒ Divide both sides by -2, this will change inequalitysign to opposite
3x - 1 > -4 ⇒ add 1 to both sides3x > -3 ⇒ divide both sides by 3x > -1 ⇒ answerx∈ (-1, ∞) ⇒ answer as setPlz help ASAP I need to get this done

f the points (-4, 1) and (2, 1) are the endpoints of a diameter of a circle, where is the center? A) (-7, 1) B) (-1, 1) C) (1, -1) D) (5, 1)
Answer:
B
Step-by-step explanation:
The centre is at the midpoint of the endpoints of the diameter.
Using the midpoint formula, then
centre = ( [tex]\frac{-4+2}{2}[/tex], [tex]\frac{1+1}{2}[/tex] ) = (- 1, 1 ) → B

Order each set of cards from least to greatest.
a. .,⎯⎯⎯⎯√,0.25 , comma , square root
Question:
Order each set of cards from least to greatest.
a. 0.25, √(1/9), (6/25)
b. √(121/25), 2.25, √5
Answer:
a. [tex]\frac{6}{25}[/tex]; [tex]0.25[/tex] and [tex]\sqrt{\frac{1}{9}}[/tex]
b. 2.2; 2.2361; 2.25
Step-by-step explanation:
Solving a. 0.25, √(1/9), (6/25)
Rewrite each number in decimals:
[tex]0.25[/tex]
[tex]\sqrt{\frac{1}{9}} = \frac{\sqrt{1}}{\sqrt{9}} = \frac{1}{3} =0.333[/tex]
[tex]\frac{6}{25} = 0.24[/tex]
At this stage, the numbers can then be ordered as follows;
0.24; 0.25; 0.333
[tex]\frac{6}{25}[/tex]; [tex]0.25[/tex] and [tex]\sqrt{\frac{1}{9}}[/tex]
Solving b. √(121/25), 2.25, √5
Rewrite each number in decimals:
[tex]\sqrt{\frac{121}{25}} = \frac{\sqrt{121}}{25}} = \frac{11}{5} = 2.2[/tex]
[tex]2.25[/tex]
[tex]\sqrt{5} = 2.2361..[/tex]
At this stage, the numbers can then be ordered as follows;
2.2; 2.2361; 2.25 which gives
[tex]2.2[/tex]; [tex]\sqrt{5}[/tex] and [tex]2.25[/tex]

4(x+9) = x+9
4 ( x + 9) = x + 9 (remove the parantheses)
4x + 36 = x + 9 (move the terms)
4x - x = 9 - 36 (collect like terms and calculate)
3x = -27 (divide both sides)
solution : x = -9
Answer:
Solution given:
4(x+9) = x+9
4x+36=x+9
4x-x=9-36
3x=-27
x=-27/3
x=-9.
