find hcf using division algorithm 867and 255
Answer :
By using EDL
a=bq+r
where a is > b
so a =867 and b=255
867=255×3+102
here r≠0 so a=255 and b=102
255=102×2+51
here r≠0 so a=102 and b=51
102=51×2+0
here r=0
so, Hcf of (867,255) is =51
Step-by-step explanation:
Hope it works out!!
Answer:
[tex]51[/tex]
Step-by-step explanation:
[tex]a=bq+r[/tex]
Where [tex]a > b[/tex]
[tex]867=255 \times 3+102[/tex]
[tex]255=102 \times 2+51[/tex]
[tex]102=51 \times 2+0[/tex]
Hcf of 867,255 is 51
What is the domain of the function on the graph? all real numbers all real numbers greater than or equal to 0 all real numbers greater than or equal to –2 all real numbers greater than or equal to –3
Explanation:
The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.
So the domain is the set of real numbers x such that x is -4 or larger
In set builder notation, that would look like [tex]\{x|x\in\mathbb{R}, \ x \ge -3\}[/tex]
In interval notation, we would say [tex][-3, \infty)[/tex] to indicate to the reader "have an interval from -3 to positive infinity; include the endpoint -3"

Answer:
x = 6.5
Step-by-step explanation:
2x - 3 = 10
2x = 10 + 3
2x = 13
x = 6.5
Answer:
Small piece is 4.3
Large piece is 5.7
Step-by-step explanation:
Let small piece be x
Large piece will be 2x-3
x + 2x - 3 = 10
3x -3 = 10
x = 13/3
Large piece will be 2*13/3 -3 = 17/3
Can somebody help me with this :) ??
Answer:
A. (5,9)
Step-by-step explanation:
First, you need to reflect across the line of reflection. Since the point is 7 units from the line y=2 from one side, it will be 7 units away when it is reflected. 2+7=9, so the reflected coordinates of the point are (-2,9). For the glide translation, you slide the point 7 units to the right, placing it at the final location of (5,9). Hope this helps!

Answer:
44 units
Step-by-step explanation:
When you perform a dilation on a figure, all of the side lengths of the figure get multiplied by the scale factor. This means that the perimeter is also multiplied by that scale factor. Since in this case that scale factor is 2, the new perimeter is 22*2=44 units. Hope this helps!
Answer:
44 units.
Step-by-step explanation:
Dilation is the transformation of an image's size by a scale factor.
The scale factor is given 2.
The rectangle has a perimeter of 22.
22 × 2 = 44
The perimeter for the resulting image is doubled by the scale factor of 2.
In the figure below, find the values of the angles given in the first column
Answer:
Angle 1 = 110 degrees
Angle 2 = 70 degrees
Angle 3 = 100 degrees
Angle 4 = 80 degrees
Step-by-step explanation:
We will first of all search for the pieces of information given in the question that can help us to solve the problem.
From the diagram, we can see that angle 3 and angle 4 are already given as
Angle 3 = 100 degrees
Angle 4 = 80 degrees
The value of angle 1 has already been supplied as 110 degrees. This leaves us with angle 2 to find.
Recall that the angles in a straight line all sum up to 180 degrees. angle 1 and 2 are on the same straight line, hence angle 2 can be found by solving 180 - 110 = 70 degrees
Angle 2 = 70 degrees
Angles A and B are the acute angles of a right triangle. If the tangent of A is 2.1445, the angle B measures

We have,
Marcus is building a model of Earth using a sphere with a surface area of [tex]400\pi\ \text{inch}^2[/tex].
It is required to find the radius of the sphere Marcus is using for his model.
The surface area of a circular shaped object is given by :
[tex]A=\dfrac{4}{3}\pi r^3[/tex]
r is radius
[tex]r=(\dfrac{3A}{4\pi})^{1/3}\\\\r=(\dfrac{3\times 400\pi}{4\pi})^{1/3}\\\\r=6.69\ \text{inch}[/tex]
So, the radius of the sphere is 6.69 inches.

Solve the rational equation 3 divided by x equals quantity 4 times x plus 3 divided by x squared, and check for extraneous solutions.
A. x = 0; x = 3 is an extraneous solution
B. x = 3; x = 0 is an extraneous solution
C. x = 0; x = −3 is an extraneous solution
D. x = −3; x = 0 is an extraneous solution
Answer:
x = -3, x = 0 is a extraneous solution
Step-by-step explanation:
Step 1: Cross-multiply
3x² = 4x² + 3x
Step 2: Isolate x's
0 = x² + 3x
Step 3: Factor
0 = x(x + 3)
Step 4: Find roots
x = 0, -3
Step 5: Double check work
Plug in both to see if they both work. Only x = 0 should be extraneous. We now have our answer!
Answer:
x = -3, x = 0 is a extraneous solution

Find the capacity in kilolitres of a cylindrical rainwater tank of height 3m and diameter 4m.
Answer:
The capacity of cylindrical rainwater tank is [tex]37.68 m^3[/tex]
Step-by-step explanation:
Height of cylindrical tank = 3 m
Diameter of cylindrical tank = 4 m
Radius of cylindrical tank =[tex]\frac{diameter}{2} = \frac{4}{2} = 2 m[/tex]
Volume of cylinder =[tex]\pi r^2 h[/tex]
Volume of cylinder tank= [tex]3.14 \times (2)^2 (3)[/tex]
Volume of cylinder tank=[tex]37.68 m^3[/tex]

What is the area of a parallelogram if the coordinates of its vertices are (0, -2), (3, 2), (8, 2), and (5, -2)?
Answer:
The area of the parallelogram is 20 unit²
Step-by-step explanation:
We have that the area of a parallelogram = Base length, l × Height, h
The length of the base, l = √((5 - 0)² + (-2 - (-2))²) = 5
Given that the base of the parallelogram is parallel with to the x-axis, we have that the height is the difference between the a higher and a lower y-coordinate as follows;
h = y₃ - y₁ = 2 - (-2) = 2 + 2 = 4
Therefore, the area of the parallelogram, A = l × h = 4 × 5 = 20 unit².

What is 3 3/4 as a fraction in its lowest term?
Please Explain it
Answer:
15/4
Step-by-step explanation:
This is because the denominator is 4 which means that there has to be 4 above it to make one:
4/4=1
So, with that being said, we do 4x3 = 12
But then we add 3 to the numerator(top number of the fraction) because the starting equation was:
3 3/4 = 15/4
