∠A and ∠B are supplementary. The measure of ∠A is 87°.
What is the measure of ∠B?
Enter your answer in the box.
Point theif = ban
Answer: The answer is BCD is 77 degree
Step-by-step explanation:
Answer:
∠B = 93°
Step-by-step explanation:
Supplementary angles are such pairs that sum up to 180°. In this case, we are given that ∠A and ∠B are supplementary. This means that the sum of ∠A and ∠B is 180°.
⇒ ∠A + ∠B = 180°
⇒ 87 + ∠B = 180°
⇒ ∠B = 180 - 87
⇒ ∠B = 93°

A. All integers are Natural numbers
B. All rational numbers are Integers
C. All natural numbers are whole numbers
D. All rational number are Natural numbers
Answer:
C, I hope this is correct or this will be embarrassing but everyone have a good day
Step-by-step explanation:
The statement about numbers is true "All natural numbers are whole numbers" which is the correct answer that would be an option (C).
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
The natural number now includes all positive integers from 1 to infinity.
Natural numbers include 1, 2, 3, 4, 5, and so on.
Whole numbers now include all positive integers from 0 to infinity.
The whole number is 0, 1, 2, 3, 4, 5, and so on.
As can be seen, every natural number are the whole number
Hence, the statement about numbers is true "All natural numbers are whole numbers"
Therefore, the correct answer would be an option (C).

explain what the standard deviation is for a set of data.
Answer:
The Standard Deviation is a measure of how spread out numbers are. You might like to read this simpler page on Standard Deviation first. But here we explain the formulas. The symbol for Standard Deviation is σ (the Greek letter sigma)
Answer:
Shows the variation in data(average of all means of the data)
Step-by-step explanation:
Ok,so, if for example, data is grouped close together, then the standard deviation will be small, if the data is more spread out then the deviation will be larger. How to tell?
Well, it all depends on the distance away from the mean. The center is usally where the mean is. How far from the mean is your data?
How to calculate?
-There are multiple equations you can use depending on your data.
If you are analyzing data which represents a larger set, use sample standard deviation, if you collect data from every member of the set, then use population standard deviation.
First, calculate the mean(average) of each set of data.
Then subtract the deviance(subtract mean from each number -/+)
Square each deviation
add up all squared deviations

Lena is reading a book. The product of the two page numbers facing each other is 5852. What is the sum of the two pages?
Answer:
first page is 12, and the facing page is 13.
Step-by-step explanation:
The pages are facing each other, so they are consecutive numbers:
Let x = the first page number
y = the second page number
The second page number is just 1 more than the first, because they are consecutive numbers:
x+1 = y
We also know that the products of the numbers is equal to 156:
xy = 5852
Now we will sub y = x+1 into the second equation:
x(x+1) = 5852
x^2 + x = 5852
x^2 + x - 5852 = 0
Factoring (or using the quadratic formula) gives us:
(x+13)(x-12) = 0
x = - 13, or x = 12.
A page number can't be negative, so we will choose x=12.
This means that the second page must be page 13.

Essentially the greater/less than shows the range of the values that are accepted or rejected + not to forget that points that lie on the parabola are rejected solutions, since i want the solutions that are strictly greater than/less than these points
If the equation suggests that it might be also equal, then the points that lie of the the parabola are also accepted solutions, since they belong to our interval [Hence the =]
Given the costs for several of the same grocery items in two countries find the rate of the total cost for these item in the united kingdom to that of the total cost of items in Canada
Rates are used to compare related quantities such as costs of items in two countries
How to determine the ratioThe question is incomplete;
So, I will give a general explanation on how to calculate the rate.
Assume that the costs are:
United Kingdom = 500
Canada = 750
The ratio would be:
Ratio = United Kingdom : Canada
So, we have:
Ratio = 500 : 750
Simplify
Ratio = 2 : 3
Express as rate
Rate = 2/3
Using the assumed values, the rate of the total cost for items in the United Kingdom to that of the total cost of items in Canada is 2/3

Based on the given segment lengths, determine whether the segments can form a triangle.
11.5,10.5, 6.1
9.5, 3.5, 4.5
8, 6.7, 1
8, 6.7, 9.8
5, 6, 8
9.5, 7.5, 8.5
For 3 sides to form a triangle two sides added together need to be greater then the 3rd side. You need to check all 3 combinations:
1. 11.5 + 10.5 = 22, 22> 6.1
11.5 + 6.1 = 17.6 17.6 > 10.5
10.5 + 6.1 = 16.6, 16.6 > 11.5
This one can make a triangle.
2. 9.5 + 3.5 > 4.5
9.5 + 4.5 > 3.5
4.5 + 3.5 < 9.5
Cannot make a triangle.
3. 8 + 6.7 > 1
6.7 + 1 < 8
Cannot make a triangle.
4. Can make a triangle
5. Can
6. Can
Can form triangle : 11.5,10.5, 6.1 & 8, 6.7, 9.8 & 5, 6, 8 & 9.5, 7.5, 8.5
Can not form triangle : 9.5, 3.5, 4.5 & 8, 6.7, 1
What is triangle inequality theorem ?
If sum of any two line segments is greater than the third line segment, then we can say that, they can make a triangle.
How to know which sets form triangle ?1st problem,
The given line segments are 11.5, 10.5, 6.1
Now, 11.5+10.5 = 22 > 6.1
10.5+6.1 = 16.6 > 11.5
11.5+6.1 = 17.6 > 10.5
So, this three segments can form triangle.
2nd problem,
The given line segments are 9.5, 3.5, 4.5
Now, 9.5+3.5 = 13 > 4.5
9.5+4.5 = 14 > 3.5
4.5+3.5 = 8 < 9.5
Here triangle inequality rule isn't applicable.
So, it can not form triangle.
3rd problem,
The given line segments are 8, 6.7, 1
Now, 8+6.7 = 14.7 > 1
8+1 = 9 > 6.7
6.7+1 =7.7 < 8
Here triangle inequality rule isn't applicable.
So, it can not form triangle.
4th problem,
The given line segments are 8, 6.7, 9.8
Now, 8+6.7 = 14.7 > 9.8
8+9.8 = 17.8 > 6.7
6.7+9.8 = 16.5 > 8
So, this three segments can form triangle.
5th problem,
The given line segments are 5, 6, 8
Now, 5+6 = 11>8
5+8 = 13 > 6
6+8 = 14 > 5
So, this three segments can form triangle.
6th problem,
The given line segments are 9.5, 7.5, 8.5
Now, 9.5+7.5 = 17 > 8.5
9.5+8.5 = 18 > 7.5
7.5+8.5 = 16 > 9.5
So, this three segments can form triangle.
