Answer:
Step-by-step explanation:
angle A + angle B + angle C = 180° [Sum of all angles of a triangle is 180°]
=> 2x+1 + x+15 + x = 180°
=> 4x + 16 = 180°
=> 4x = 180° - 16°
=> 4x = 164°
=> x = ([tex]\frac{164}{4}[/tex])°
=> x = 41°
[tex]\\[/tex]
angle A = 2x+1 = 2×41 +1 = 82 + 1

angle B = x+15 = 41+15

If 4.6 plus 1.9 times a number equals the sum of the number and 94.6, what is the number? Express your answer as a simplified fraction or a decimal rounded to two places.
Answer:
The number is:
x=99.67Step-by-step explanation:
Let 'x' be the number
4.6 plus 1.9 times a number 'x' = 4.6 + 1.9xSum of number 'x' and 94.6 = x+94.6Given that 4.6 plus 1.9 times a number equals the sum of the number and 94.6.
so the equation becomes
[tex]4.9+1.9x=x+94.6[/tex]
[tex]1.9x-x=94.6-4.9[/tex]
[tex]0.9x=89.7[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]
[tex]0.9x\cdot \:10=89.7\cdot \:10[/tex]
[tex]9x=897[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9x}{9}=\frac{897}{9}[/tex]
[tex]x=\frac{299}{3}[/tex]
[tex]x=99.67[/tex]
Therefore, the number is:

Suppose the line of best fit is drawn for some data points. If the mean of the
x-coordinates of the points is 5, and the mean of the y-coordinates of the
points is - 7 the line must pass through which of these points?
A. (-7,5)
B. (7-5)
C. (5, -7)
D. (-5,7)
the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).
How to find the coordinates?
To determine which point the line of best fit passes through, we need to use the fact that the line passes through the centroid of the data points. The centroid is the point (mean of x-coordinates, mean of y-coordinates).
Given that the mean of the x-coordinates is 5 and the mean of the y-coordinates is -7, the centroid is (5, -7). Therefore, we need to look for the point among the given options that has coordinates (5, -7).
The point (5, -7) is not listed as an option, but we can find the point that is closest to it.
Option A (-7,5) has the coordinates switched, so it cannot be the correct answer. Option B (7-5) is not a valid point since it is missing a comma between the x and y coordinates. Option D (-5,7) has the correct x-coordinate but the wrong y-coordinate.
Therefore, the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).

point P lies on the origin of a coordinate system. if you translate the point 5 units up, then 4 units left, then 4 units down, the result is point P. what are the coordinates of point P
Answer:
The coordinates of point P after all the translations become: (-4, 1)
Step-by-step explanation:
The point P lies on the origin of a coordinate system.
i.e. P(0, 0)
Translating point 5 units up will translate the coordinates from (0, 0) to :
(x, y) → (x, y+5)
(0, 0) → (0, 0+5) = (0, 5)
THEN
Translating point 4 units left will translate the coordinates from (0, 5) to :
(x, y) → (x-4, y)
(0, 5) → (0-4, 5) = (-4, 5)
THEN FINALLY
Translating point 4 units down will translate the coordinates from (-4, 5) to :
(x, y) → (x, y-4)
(-4, 5) → (-4, 5-4) = (-4, 1)
Therefore, the coordinates of point P(0, 0) after translating point 5 units up, then 4 units left, then 4 units down will be:
(x, y) → (x, y+5) → (x-4, y+5) → (x-4, y+5-4)
(0, 0) → (0, 0+5) → (0-4, 0+5) → (0-4, 0+5-4) = (-4, 1)
Hence, the coordinates of point P after all the translations become: (-4, 1)

Fomular for finding perimeter area and circumference of a circle
Answer:
perimeter of a circle=2πR
The perimeter of a circle is the circumference of the circle.
CIRCUMFERENCE
There are two formulas:
1. C = πd (use if the problem gives you the diameter only)
2. C = 2πr (use if the problem gives you the radius only)
AREA
There are several area formulas for a circle but I think for you at your level of math, A = πr^2 is all you need to know.

Number of items sold, discrete; time spent at desk, continuous
O Unable to determine from information given
Answer:
Number of items sold, discrete; time spent at desk, continuous
Step-by-step explanation:
The random variables from the survey is number of items sold, discrete; time spent at desk, continuous
What is random selection ?A selection that is chosen randomly (purely by chance, with no predictability). Every member of the population being studied should have an equal chance of being selected.
According to the question
The supervisor at an office randomly selected 45 employees and observed their work habits.
She recorded
i > number of items sold
ii > total time the employees spent at their desk
As per observation
Number of items sold = discrete
as it is not possible to sell items in a continuous manner
But
time spent at desk = continuous
as every employee spend time at there desk
Hence, the random variables from the survey is number of items sold, discrete; time spent at desk, continuous

Which graph represents points on the polar curve r = 2 + 5sin(θ)?
Answer:
Graph 2
Step-by-step explanation:
See image attached. Hope this helps.
The second graph shown the polar curve at r = 7.
Given ,
Equation of polar curve = r = 2 + 5sin(θ)
We have to find ,
Which of following graph show polar curve ,
At r = 2 + 5sin(θ)
The area between two curves in the polar coordinate system, first find the points of intersection, then subtract the corresponding areas.
First graph ; r = 2 + 5sin(θ)
Where ,
[tex]\theta = 0[/tex]
r = 2 + 5sin0
r = 2 + 5 (0)
r = 2
Second graph : r = 2 + 5sin(θ)
Where
[tex]\theta = \frac{\pi }{2}[/tex]
Then,
r = 2 + sin[tex]\frac{\pi }{2}[/tex]
r = 2 +5 ( 1 )
r = 2+5
r = 7
Third graph ; r = 2 + 5sin(θ)
where
[tex]\theta = \pi[/tex]
Then,
r = 2 + 5sin[tex]\pi[/tex]
r = 2 + 5(0)
r = 2
Fourth graph ; r = 2 + 5sin(θ)
Where
r = 2 + 5sin[tex]\frac{3\pi }{2}[/tex]
r = 2 + 5 (-1)
r = -3
Fifth graph ; r = 2 + 5sin(θ)
Where
[tex]\theta = 2\pi[/tex]
r = 2 + 5sin(2π)
r = 2+ 5 (0)
r = 2
Comparing all the value of the graph ,the second graph shown the polar curve at r = 7.
Hence, The second graph shown the polar curve at r = 7.

I just need the steps....
Answer:
45 cm^2
Step-by-step explanation:
Dividing the shape into the two separate components of a square and a triangle makes it easier.
The square area is found by multiplying the side by the side, 6cm*6cm which gives us 36cm^2.
Then the triangle the height is 3cm and the base is 6cm. Using the formula 1/2*base*height.
Which would be 1/2*6*3=9cm^2.
Adding the two, 9+36= 45cm^2.

Answer:
a) x=0, x=1
b)x=0, x=4/3
Step-by-step explanation:
I didnt use the graph, just used algebra. For part a, you can find the answers using the graph by looking at the value of x when y = whatever value they give.
A)
3x²-3x+2=2
3x²-3x+0
x(3x-3)=0
For the product of two things to equal zero, one of them has to be zero. For example, if ab=0, then either a or b (or both) are zero.
Therefore..
x=0
or 3x-3=0, ∴x=1
b)
3x²-3x-1 = x-1
3x²-4x=0
x(3x-4)=0
∴x=0, x=4/3

Given the figure below, find the values of x and z.
x =
(13x + 30)
z =
(12x + 50)
Answer:
x = 4
z = 92°
Step-by-step explanation:
From the picture attached,
Two straight lines are intersecting each other at a point so that,
(12x + 50)° + (13x + 30)° = 180° [Linear pair of angles]
25x + 80 = 180
25x = 100
x = 4
Therefore, measure of (13x + 40)° = 13×4 + 40
= 52 + 40
= 92°
Since, z° = (13x + 40)° [Vertically opposite angles]
Therefore, z° = 92°
