Find the HCF of 200 and 240
Answer:
its 40
Step-by-step explanation:
200 and 240 have an HCF of 40.
Finding all common factors between two numbers and choosing the biggest one yields the highest common factor (HCF).
So, let's determine factors of 200
1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200 are all factors of 200.
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, and 240 they are all factors of 240.
now, we will select the highest common factors of 200 and 240.
the highest common factors of 200 and 240 is 40.
Hence, the HCF of 200 and 240 is 40.

ii) (1, 3), (6,3), (6, 6) and (1, 6) are the vertices of a rectangle.
Given, (1, 3), (6,3), (6, 6) and (1, 6) are the vertices of a rectangle, the width is 1 unit shorter.
What is a rectangle?A rectangle is a quadrilateral with the four right angles in the Euclidean plane. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°). A square is a rectangle with the four equally long sides. Oblong is occasionally used to describe a rectangle that isn't square. Rectanglen is the symbol for a rectangle having the vertices ABCD. ABCD in PNG.
Rectangulus, a combination of rectus (as an adjective, right, proper), and angulus, is the source of the English word rectangle (angle).
A crossed rectangle is a quadrilateral that is formed by the intersection of two diagonals and the two opposite sides of a rectangle (therefore only two sides are parallel). Although opposite angles are equal, it is a specific example of an antiparallelogram in which the angles are not all right angles and equal. There exist so-called rectangles in other geometries, including spherical, elliptic, and hyperbolic ones, with opposite sides of equal length and equal angles that are not right angles.
Many tiling issues use rectangles, like tiling the plane with rectangles or tiling a rectangle with polygons.
By plotting given points in the coordinate plane,
We get rectangle ABCD having vertices,
A(-1,6), B (3,6), C (3,1), D (-1,1)
By distance formula,
Shorter side or width of rectangle,
AB= [tex]\sqrt{ [3-(-1)]^{2}+ (6-6)^{2}} = \sqrt{4^{2}+0 } = 4 units[/tex]
Longer side or length of rectangle,
BC= [tex]\sqrt{(3-3)^{2}+(1-6)^{2}}=\sqrt{5^{2} } = 5 units[/tex]
The difference between length and width,
BC-AB= 5-4= 1units
Hence, width of rectangle is 1 unit less than the length.

A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in. If the container holds 1096 cubic feet of shipped goods, what percent is empty?
As per the volume of a rectangular prism, it is found that 34.76% of the container is empty.
Volume of a rectangular prism
The volume of the rectangle prism is calculated by multiplying the length, breadth and height of the prism.
The formula for the volume of rectangle prism is
V = l x w x h
where
l represents the length
w represents the width
h represents the height
Given,
A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in.
Here we need to find if the container holds 1096 cubic feet of shipped goods, what percent is empty
According to the given question,
Let us consider the length is 30ft, Width is 8ft and Height is 7ft.
Here the value 3ft refers the depth.
That one is also multiplied with the volume.
Therefore, the volume of the container is
=> 8 x 7 x 30
=> 1680
Therefore, the volume of the container is 1680 cubic feet.
So, here we have to percentage of the empty space for that we have to find the difference of them and convert it into percentage,
=> 1680 - 1096
=> 584
The percent of empty space is,
=> x% of 1680 = 584
=> x% = 584/1680
=> x% = 0.3476
=> x = 34.76
Therefore, 34.76% of rectangular prism container is empty.

a box with a square base and open top must have a volume of 42592 c m 3 . we wish to find the dimensions of the box that minimize the amount of material used. first, find a formula for the surface area of the box in terms of only x , the length of one side of the square base. [hint: use the volume formula to express the height of the box in terms of x .] simplify your formula as much as possible. wyzant
a formula for the surface area of the box in terms of only x , the length of one side of the square base is A = x² + 170368 cm³/x
The volume of the box with square base is V = x²h where x = length of side of square base and h = height of box.
Now, the area of the of box open at the top with dimensions of length, l , width, w and height, h are
A = 2lh + lw + 2wh
Now for a box of square base, l = w = x.
So, A = 2xh + x² + 2xh
A = x² + 4xh
Since V = x²h and V = 42592 cm³,
h = V/x² = 42592/x²
substituting h into A, we have
A = x² + 4xh
A = x² + 4x(42592 cm³/x²)
A = x² + 4 × 42592 cm³/x
A = x² + 170368 cm³/x

B=
It can be written in the form is like ax+b/x^2-9
so we only need the A and B.
Please reply to this ASAP
Step-by-step explanation:
so, if I understand your text correctly, we need to bring
2 - (x+2)/(x-3) - (x-6)/(x+3)
into a form
(ax + b)/(x² - 9)
what we notice immediately is
(x+3)(x-3) = x² - 9
that makes sense, as we want to transform all terms into fractions with the same denominator.
and the necessary "criss-cross" multiplication leads to (x² -9) as denominator.
so, let's transform every term to a fraction with that denominator, and then we add or subtract them all up as per the original expression.
2 :
multiply by (x²-9)/(x²-9)
2(x²-9)/(x²-9) = (2x²-18)/(x²-9)
(x+2)/(x-3) :
multiply by (x+3)/(x+3)
(x+2)(x+3)/(x²-9) = (x²+3x+2x+6)/(x²-9) =
= (x²+5x+6)/(x²-9)
(x-6)/(x+3) :
multiply by (x-3)/(x-3)
(x-6)(x-3)/(x²-9) = (x²-3x-6x+18)/(x²-9) =
= (x²-9x+18)/(x²-9)
for the whole expression we get then
(2x²-18)/(x²-9) - (x²+5x+6)/(x²-9) - (x²-9x+18)/(x²-9) =
= (2x²-x²-x² -5x+9x -18-6-18)/(x²-9) =
= ( 0 + 4x - 42 )/(x²-9)

1.if the m∠7 = 115° , find the measure of ∠2
Show your work
Answer: The measure of is 115°.
Step-by-step explanation:
Now, assuming those angles are supplementary, then
m<7 + m<2 + 180
Because, supplementary angles sum 180\°, due to their position on a straight angle.
We know by given that m<7 = 115 , replacing this value, we have
115 + m<2 + 180
m<2 = 180 - 115

What is a function?A relation between a collection of inputs and one output for each of those inputs is the definition of a function.
A function is a connection between inputs in which each input is associated with precisely one output.
To put it another way, a function is a relationship between inputs. Each function has both a domain and a codomain or range that it operates inside.
Generally, The progression towards
g(x) = f(x -h) +k
depicts a translation with k units added on top and h units added to the right.
Since you have h equal to 0 and k equal to -2, this means that the graph is moved 0 units to the right and 2 units in the opposite direction of up.

Hi I have question on solving algebraic fractions. How would I find the LCD for this?
(x/x+1)+(x-1/4)=(11/12)
I tried multiplying the denominator by the opposites (x+1 and 4) to make them the same denominator and then add them and cross multiply, however, I never got the right answer
The value of x is either 2 or -7/3.
Given expression:-
(x/x+1)+((x-1)/4)=(11/12)
We have to find the value of x.
The LCM of (x + 1) and 4 is 4(x - 1).
We can write,
[4x + (x + 1)(x - 1)]/4(x + 1) = 11/12
[tex]\frac{4x+x^2-1}{4(x+1)}=\frac{11}{12}[/tex]
We can multiply 4 to the given equation, and get,
[tex]\frac{4x+x^2-1}{(x+1)}=\frac{11}{3}[/tex]
By cross multiplying, we can write,
[tex]12(4x+x^2-1)=11(4(x+1))[/tex]
12x + [tex]3x^2[/tex] -3 = 11x + 11
[tex]3x^2[/tex] + 12x - 11x -3-11 = 0
[tex]3x^2[/tex] + x-14 = 0
Using the middle-term split theorem, we can write,
[tex]3x^2[/tex] + 7x - 6x -14 = 0
x(3x + 7) - 2(3x + 7) = 0
(3x + 7)(x - 2) = 0
