Find the value of angle MIJ
Answer:
the value of ∠MIJ is 125
Step-by-step explanation:
You can assume ∠ JIK and ∠MIL are the same and would add to 110 degrees. we know a circle can only contain 360 degrees so if you take 360 - 110 = it leaves 250. and ∠LIK and ∠MIJ are equivalent so if you take your remainder of 250 and divide it by 2 you get 125 degrees.

Answer:
The answer to your question is 26.75
Step-by-step explanation:
Top triangle = 3.5 x 9 = 31.5. Since it is a triangle, it has to be split in half (15.75).
Bottom left triangle = 2 x 2 = 4. Since this is also a triangle: 4 split in half is 2.
Bottom square = 2 x 2 = 4.
Bottom right triangle = 5 x 2 = 10. Since it is a triangle, 10 / 2 = 5.
After you get the area of each individual shape, add them together to get 26.75.

Which box plot correctly summarizes the data?
The right box plot that summarizes the data should look like the one constructed below in the diagram attached.
We are given the data set 25, 28, 29, 29, 30, 34, 35, 35, 37, and 38, which are already in order and we need to derive the min, max, median, Q1, and Q3 from the given data set. We need all of these values to construct a box plot to summarize the data.
Now, we will find the minimum value which is 25. The maximum value in the data set is 38. The median is the middle value of the data set and it will lie between the 5th and the 6th data points. The average of both values would give us our median data point = (30 + 34) ÷ 2 = 32
Our Q1 would be the middle data point of the bottom half of the data set which is 29. Q3 would be the middle data point of the top half of the data set = 35. As we have derived these values, we can now construct a box plot to summarize the given data.
Therefore, the right box plot that summarizes the data should look like the one constructed below in the diagram attached.

Mrs. Giavis has 26 marbles in a bag. She has 13 blue marbles, 10 red marbles, and 3 yellow marbles. What is the probably that Mrs. Giavis will pick a blue marble, not replace it, and then randomly pick a red marble?
Given:
Total number of marbles = 26
Number of blue marbles = 13
Number of red marbles = 10
Number of yellow marbles = 3
To find:
The probability of getting a blue marble then a red marble (without replacement).
Solution:
Total number of marbles = 26
Number of blue marbles = 13
Probability of getting a blue marble is first draw is:
[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(Blue)=\dfrac{13}{26}[/tex]
[tex]P(Blue)=\dfrac{1}{2}[/tex]
After drawing 1 marble, the remaining number of marbles in the bag is 25.
Probability of getting a red marble is second draw is:
[tex]P(Red)=\dfrac{\text{Number of red marbles}}{\text{Remaining number of marbles}}[/tex]
[tex]P(Red)=\dfrac{10}{25}[/tex]
[tex]P(Red)=\dfrac{2}{5}[/tex]
Now the probability of getting a blue marble then a red marble (without replacement) is:
[tex]P(\text{Blue then red})=P(Blue)\times P(Red)[/tex]
[tex]P(\text{Blue then red})=\dfrac{1}{2}\times \dfrac{2}{5}[/tex]
[tex]P(\text{Blue then red})=\dfrac{1}{5}[/tex]
Therefore, the probability of getting a blue marble then a red marble (without replacement) is [tex]\dfrac{1}{5}[/tex].

An angle measures 62.6° less than the measure of its complementary angle. What is the
measure of each angle?
and
Answer:
The angles are 13.7 degrees and 76.3 degrees
Step-by-step explanation:
Let the complementary angle be x
When two angles are complementary, they add up to 90 degrees
So if one is x , the other would be (x-62.6) as stated by the question
so, adding this two will give 90 degrees
We have this as;
x + x -62.6 = 90
2x = 90 + 62.6
2x = 152.6
x = 152.6/2
x = 76.3
The other angle will be;
76.3 -62.6 = 13.7

Hope this helps!
Answer:
2, 6, and 7.
Step-by-step explanation:
In a right triangle, the hypotenuse (longest side of the triangle) squared is equal to the sum of the other sides squared.
So for the second triangle, add 36 squared to 15 squared. The result is 1521. Compare that to the hypotenuse (39) squared. The second triangle is a right triangle because the hypotenuse squared is also 1521. I did this with each triangle and the 2nd, 6th, and 7th were right triangles.

how many solutions does x + 2x + 7 = 3x - 7
Answer:
No solutions! :)
Step-by-step explanation:
To find the number of solutions in a problem we must solve it.
x+2x+7=3x-7
Firstly, combine common terms:
3x+7=3x-7
We can subtract 3x from both sides:
7=-7
The solution is 7=-7, which is no solution.

Find the measure of the missing angles.

h=
m=
k=
(NO FILES) YOU WILL GET MARKED BRAINLY :)!!
Answer:
g. 92*
h. 88*
m. 89*
k. 91*
Step-by-step explanation:
To find h and m: All of the angles on a straight line added up equals 180*. So if there are two angles, the sum of them must equal 180* (angle A + angle B = 180*)
So in this case we have angle h + 92* = 180* using algebra, we subtract 92 from both sides and we get angle h = 88*
If you want to check, add 92 + 88 = 180.
Also angle m + 91* = 180*. Same thing as above, subtract 91 from both sides and we get angle m = 89*
If you want to check, add 91 + 89 = 180.
When you have two straight lines intersecting (crossing), the opposing angles at that crossing are going to be equal. So in this case angle g is opposite from the anbgle that we know is 92*, so angle g is also 92*. Same thing for angle k, we know the angle opposite angle k is 91*, so we know that angle k is also 91*.

5(y+25)=−13 what is y
Answer:
y = -27.6
Step-by-step explanation:
To solve for y, you need to isolate the variable on one side of the equation. [tex]5(y+25)=-13[/tex] ⇒ [tex]y + 25 = -2.6[/tex] ⇒ [tex]y = -27.6[/tex].
Answer:
-27.6
Step-by-step explanation:
[tex]5(y + 25) = -13[/tex]
First, distribute the problem.
[tex]5y + 125 = -13[/tex]
Secondly, subtract 125 from -13 and 125.
[tex]125 - 125 = 0[/tex]
[tex]-13 - 125 = -138[/tex]
Now, we are left with 5y = -138.
Lastly, we divide -138 by 5.
[tex]-138 / 5 = -27.6[/tex]
Therefore, y is -27.6.

A T-shirt company bought a new packaging and tracking system for $100,000. The formula V=100,000(1-0.125) models the value of the
system V, in dollars, after depreciating for y years.
In this formula, what is the meaning of the term (1-0.125)?
Α. The value of the system will decrease by 12.5% each year.
.
В. The value of the system will be $0 in 12.5 years.
С The value of the system will decrease by $12.50 each year.
DThe value of the system will continue to decrease for 125 years.
Answer: c
Step-by-step explanation:
The term ( 1 -0.125) is a decay factor which means the value of system decreased by 12.5% each year.
What is exponential decay?The process of reducing an amount by a consistent percentage rate over a period of time is called exponentially decay.
Exponentially decay rate formula[tex]y = a(1-r)^{x}[/tex]
a is initial amount
1-r is decay factor
x is time period
According to the given question.
We have a exponential function.
[tex]V = 100,00(1-0.125)^{y}[/tex]
If we compare the above function with exponential decay rate formula i.e.
[tex]y = a(1-r)^{x}[/tex]
We get,
a = 100,000
r = 0.125
In [tex]V = 100,000(1-0.125)^{y}[/tex], the term ( 1 -0.125) is a decay factor which means the value of system decreased by 12.5% each year.
Thus, option A is correct.
