Answer: 61 is NOT a solution. The first thing I did was replace the variable (x) with 61, afterwards I rewrote the equation as 61+ 23= 82, if you add 61 by 23 you'll get 84! 84>82, which proves 61 is not a solution!
Step-by-step explanation:
Answer:
NoStep-by-step explanation:
x +23 = 82x = 82 - 23x = 59Since 59 ≠ 61, the answer is NO

option 2: 15
Step-by-step explanation:
ΔBOA is a right angled triangle.
By Pythagoras theorem,
[tex] {oa}^{2} = {bo}^{2} + {ba}^{2} [/tex]
[tex] {oa}^{2} = { {9}^{2} } + {12}^{2} [/tex]
[tex] {oa}^{2} = 81 + 144 [/tex]
OA = √225
OA = 15
If the 12-sided solid is rolled 180 times, how many times would you expect either number a 3, 9 or 11 to be rolled?
The probability that the 12-sided solid gets 3 , 9 or 11 is P ( A ) = 1/4 and the expected number of times is n = 45
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability that the the 12-sided solid gets 3 , 9 or 11 be P ( A )
Now , the value of P ( A ) is
Let the number of outcomes when rolling a 12-sided solid = 12
The number of times the solid is rolled = 180 times
So , the total number of outcomes = 12 x 180 = 2160
And , the probability of getting a 3 = 1/12
The probability of getting a 9 = 1/12
The probability of getting a 11 = 1/12
So , the total probability of getting a 3 , 9 or 11 = 3/12 = 1/4
The total expected number of times = 45
Hence , the probability is 1/6

2cos² 34° - 1 expressed as a single trigonometric ratio? (With explanation of steps please)
Answer:
Cos 68
Step-by-step explanation:
Given the expression 2cos² 34° - 1, we are to expression as a single trig ratio.
Let the angle be theta
Recall that sin²theta + cos²theta = 1
sin²theta = 1 - cos²theta ... 1
also Cos 2theta = Cos²theta - sin²theta ... 2
Substitute 1 into 2
Cos 2theta = Cos²theta - (1-cos²theta)
Cos 2theta = Cos²theta - 1 + cos²theta
Cos 2theta = 2Cos²theta - 1
Replace theta with 34
Cos 2(34)= 2Cos²(34)- 1
Cos 68 = 2Cos²(34)- 1
Hence the single trig expression is Cos 68

Write the slope-intercept form of the line that travels through (4,-1) and is parallel to y = 1/4x
Answer:
y = 1/4x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 1/4x. Its slope is 1/4. A line parallel to this one will also have a slope of 1/4.
Plug this value (1/4) into your standard point-slope equation of y = mx + b.
y = 1/4x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (4, -1). Plug in the x and y values into the x and y of the standard equation.
-1 = 1/4(4) + b
To find b, multiply the slope and the input of x (4)
-1 = 1 + b
Now, subtract 1 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 1/4x - 2
This equation is parallel to your given equation (y = 1/4x) and contains point (4, -1)

Answer:
x = 99°
Step-by-step explanation:
first: find the supplement to 123°:
180 - 123 = 57°
second: since all triangle interior angles total a80°:
180 - 42 - 57 = 81°
third: x = the supplement to 81°, so, x = 180 - 81 = 99°

The given vertices are (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5).
We need to plot the given vertices on the graph.
How to plot the given points on the graph?A point in a plane contains two components where order matters! It comes in the form (x, y) where x comes first, and y comes second.
The x-value tells how the point moves either to the right or left along the x-axis. This axis is the main horizontal line of the rectangular axis or Cartesian plane.The y-value tells how the point moves either up or down along the y-axis. This axis is the main vertical line of the rectangular axis or Cartesian plane.We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.
