Step-by-step explanation:
not sure where the click but the angles of 52 degree angle
The measure of the angle x in the given figure is 142°.
What is an angle?When two lines meeting at a point, it will form angle.
We know that, if two lines meeting at a point and forms a straight line then the angle on the either side of the line is 180°.
Here, in the given figure: (x + 38°) = 180°
Therefore the measure of the angle x = (180° - 38°) = 142°.

Choose an acre of land in Canada at random. The probability is 0.45 that it is forest and is 0.03 that it is pasture. What is the probability that the chosen acre is not forested?
a. 0.03
b. 0.45
c. 0.55
Answer:
c. 0.55
Step-by-step explanation:
A chosen acre of land is forested and not forested are complimentary event , so let :
F = Chosen land is forested
F = Chosen land is not forested
....and we know F+F = S
where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so
P(F+F) = P(S)
P(F) + P(F)=1
We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so ,
0.45 + P(F) = 1
P(F) = 1 - 0.45
P(F) = 0.55
Hence, the probability that the chosen acre is not forested is 0.55

A company logo has 4 concentric circles. Suppose you graph the points (diameter, circumference) and connect them with a line. In terms of pi, what is the slope of the resulting line?
Answer:
Step-by-step explanation: they will form a straight line, passing through the origin.
let the radius of the first one be r
then the first point is (2r, 2πr)
slope of line passing through (0,0) and (2r, 2πr)
= (2πr)/(2r)
= π
The slope of the resulting line is π.

In a rectangle, the length is 7 m less than three times the width and the area is 111 m. Approximate the dimensions to the nearest tenth of a meter.
Answer:
The dimensions are 7.4m by 15.1 m (to the nearest tenth).
Step-by-step explanation:
Area = length * width
If the width = x then the length = 3x - 7 so
Area x(3x - 7) = 111
3x^2 - 7x - 111 = 0
Using the quadratic formula:
x = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)
x = 7.36, -5.03.
The width must be positive s it is 7.36 m.
The length = 3(7.36) - 7
= 15.08 m.

And this is an ending, meaning it doesn't go on forever.However, we don't know what [tex]y[/tex] is. So because we don't know what [tex]y[/tex] is we still graph it but it'll go on forever.- You can either graph this like this, OR graph this using desmos.com.
Vertical or Horizontal? [tex]x=[/tex] Horizontal, Left and Right.[tex]y=[/tex] Vertical, Up and Down.- So since we know [tex]x[/tex] is, (Horizontal,) we have to graph [tex]y[/tex], (Vertical.) So to sum this up, this just means whatever variable you don't know yet, that will be the one that you graph as an infinite.

Step-by-step explanation:
1) The answer is D
g(x) = 2x-8 if we put the corresponding values of x in the table we get the exact same values of y example
[tex]g(x)=2x-8\\g(5)=2(5)-8\\g(5)=2\\g(7)=2(7)=8\\g(7)=6[/tex]
so we can see that our values match with the table's values for part D)
2)The answer is C
Range corresponds to the values of y and here the function in the image shows the maximum value of y is 2 and then it decreases to 1 , 0 , -1 and so on so option C is correct y<2

B) -2, -4, -8, -16, -32, ...
OC) 0, 6, 12, 18, 24, ...
OD 1, -3, 9, -27, 81,...
Answer:
b. -2,-4,-8,-16,-32 thats the answer i think
The arithmetic sequences are:
B) -2, -4, -8, -16, -32, ...
C) 0, 6, 12, 18, 24, ...
The correct options are B and C.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
An arithmetic sequence is a sequence of numbers where each term is obtained by adding a fixed number, called the common difference, to the previous term. We can check which of the given sequences satisfy this definition:
A) 0, 5, 11, 18, 24, ...
The common difference between consecutive terms is not the same: the difference between the first two terms is 5, the difference between the second and third terms is 6, the difference between the third and fourth terms is 7, and so on. Therefore, this sequence is not an arithmetic sequence.
B) -2, -4, -8, -16, -32, ...
The common difference between consecutive terms is multiplied by -2: the difference between the first two terms is -2(-2) = 4, the difference between the second and third terms is -4(-2) = 8, the difference between the third and fourth terms is -8(-2) = 16, and so on. Therefore, this sequence is an arithmetic sequence with a common difference of -2.
C) 0, 6, 12, 18, 24, ...
The common difference between consecutive terms is 6. Therefore, this sequence is an arithmetic sequence with a common difference of 6.
D) 1, -3, 9, -27, 81,...
The common difference between consecutive terms is multiplied by -3: the difference between the first two terms is -3, the difference between the second and third terms is -3(-3) = 9, the difference between the third and fourth terms is -9(-3) = 27, and so on. Therefore, this sequence is not an arithmetic sequence.
Therefore, the arithmetic sequences are options B and C.

The ratio of boys to girls in band class was 3 to 5. If there were 24 boys. How many girls were in band class?
Answer:
40 girls
Step-by-step explanation:
Set up a proportion where x is the number of girls in band class:
[tex]\frac{3}{5}[/tex] = [tex]\frac{24}{x}[/tex]
Cross multiply and solve for x:
3x = 120
x = 40
So, there were 40 girls in band class.
Answer: There are 40 girls in band class.
____________________________________________________________
The ratio for this problem is:
[tex]\frac{3}{5} = \frac{24}{x}[/tex]
To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.
5 times 8 equals 40.
There are 40 girls in band class.
solve for x, if m<2 = 2+6x
Answer:
x = 6
Step-by-step explanation:
Since the triangles are isosceles the two bottom angles are equal. So, 71 + 71 + 2 + 6x would help us find x. Now to solve it.
71 + 71 + 2 + 6x = 180
142 + 2 + 6x = 180
144 + 6x = 180
6x = 180 -144
6x/6 = 36/6
x = 6

Answer:
n = 1.5
Step-by-step explanation:
So, you left off on where we subtracted 40 from both sides.

4n = -6
Now, divide both sides by 4 to ultimately isolate the variable:
4n/4 = -6/4
