Answer:
A quadrilateral's interior angles have a sum of 360°.
Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.
We can add these angles plus the unknown angle to equal a total of 360°.
85 + 100 + 90 + x(our unknown missing angle) = 360
simplify
275 + x = 360
Isolate x by subtract 275 from both sides;
-275 -275
x = 85, ∠1 = 85°
We can also double check:-
85 + 100 + 90 + 85 = 360
360 = 360 which is correct.

Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?
Answers
Answer: 16
Step-by-step explanation:
Find the mean absolute deviation of the data:
X : 92, 88, 90, 96, 84
Find the mean(m) of the data:
m = Σ(X) / n
n = number of samples
(92 + 88 + 90 + 96 + 84) / 5
m = 450 / 5
m = 90
Absolute Deviation of each value of the mean:
|x - m| :
|92 - 90| = 2
|88 - 90| = 2
|90 - 90| = 0
|96 - 90| = 6
|84 - 90| = 6
Σ|x - m| = 2 + 2 + 0 + 6 + 6 = 16

On a circle with radius 12 m, what angle would subtend an arc with a length of 7 m?
Answers
Answer:
33.42
Step-by-step explanation:
just trust me
33.42 angle would subtend an arc with a length of 7 m.
How do you find the angle of an arc?The angle formed by the arc at the center of the circle is the angle of the arc. Indicated by. m A B ^, A, and B are the endpoints of the arc. You can use the arc length equation to find a measure of the arc angle.
For a circle, the arc length equation is θ times the radius of the circle. The equation for arc length in radians can be expressed as Arc length = θ × r, where θ is in radians. Arc length = θ × (π / 180) × r, where θ is in degrees and L = arc length. θ = central angle of the arc.

1/x-x/6=2/3 how to answer this
Answers
Answer:
x = 0.1
Step-by-step explanation:
1/x - x/6 = 2/3
1/ x - 6/x = 2/3
6/x = 2/3
6x = 2/3
x = 0.1
Answer:
x = 0.2
Step-by-step explanation:
1/x - x/6 = 2/3
=> 1/x - x = 2/3 * 6
=> 1/x - x = 12/3
=> 1/x - x = 4
=> 1/x - x/1 = 4 (x = x/1 )
=> 1 - x/1 = 4 * x
=> -x/1 = 4x - 1
=> -x/1 -4x = -1
=> -5x/1 = -1
=> x = -1/-5
=> x = 0.2 (Because negative / negative = positive)

We have two points, so we can use the slope formula
m = ( y2-y1)/(x2-x1)

Find X to complete the following ratio. 12:5 = 24:X
Answers
Answer:
x = 10
Step-by-step explanation:
This is the answer because:
1) 12:5 is equivalent to the ration 24:10
2) This is because to get 24 you have to multiply 12 and 2 which is 24
3) Next, you have to do the same to the other side to make everything equal. Therefore, you have to multiply 5 with 2 which is 10.
4) Finally, your answer should be 24:10

A. {−3.5, −2, 1, 2.5}
B. {−3, 6, 24, 33}
C. {−63, −9, 99, 153}
D. {−0.5, 1, 4, 5.5}
Answers
Answer:
A. {−3.5, −2, 1, 2.5}
Step-by-step explanation:
Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:
y=9+6x
6x=y-9
[tex]x=\frac{y-9}{6}[/tex]
So we just insert the values, the first one being -12.
[tex]x=\frac{y-9}{6}\\x=\frac{-21}{6}\\x=\frac{-12-9}{6}\\x=-3.5[/tex]
So since from the options only A has -3.5 as an option that's the correct answer.
