Answer:
x = 40°
Step-by-step explanation:
In order to answer this problem, you will need to know the definition of an isosceles triangle.
An Isosceles triangle is specified as a triangle with 2 of its 3 sides having equal lengths.
Step 1: Draw your triangle.
Since 2 of your 3 sides are equal length and the primary angle measures 100°, you are dealing with an obtuse triangle or, properly named, a obtuse isosceles triangle.
Step 2: Label your angles inside of your triangle.
Remember that the sum of the angles inside of a triangle must add up to equal 180°.
Since we know the triangle we are dealing with in this problem, we can label our unknown angles 'x'.
Caution: The above statement ONLY applies to this type of triangle.
Step 3: Write an equation.
100° + x° + x° = 180°
Step 4: Solve for x.
100° + x° + x° = 180°
100° + 2x° = 180°
2x = 80°
x = 40°
help!!
a teacher asks five students to write an equation with a solution of x= 4 . the students and their equations are shown below. which of the following students correctly wrote an equation with x= 4 as the solution ? select three that apply
Answer:
[tex](b)\ 2x - 9 = -1[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]
Step-by-step explanation:
Required
Which equals [tex]x = 4[/tex]
[tex](a)\ 2x + 6 = 2[/tex]
Collect like terms
[tex]2x = 2 - 6[/tex]
[tex]2x = -4[/tex]
Divide both sides by 2
[tex]x = -2[/tex]
[tex](b)\ 2x - 9 = -1[/tex]
Collect like terms
[tex]2x = -1 + 9[/tex]
[tex]2x = 8[/tex]
Divide both sides by 2
[tex]x = 4[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
Collect like terms
[tex]-2x =- 12 + 4[/tex]
[tex]-2x =-8[/tex]
Divide both sides by -2
[tex]x = 4[/tex]
[tex](d)\ 2(x + 2) = 10[/tex]
Divide both sides by 2
[tex]x + 2 =5[/tex]
Collect like terms
[tex]x = 5-2[/tex]
[tex]x = 3[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]
Divide both sides by 2
[tex]x - 10 = -6[/tex]
Collect like terms
[tex]x = 10 - 6[/tex]
[tex]x = 4[/tex]
Hence, the equations with the required solution are:
[tex](b)\ 2x - 9 = -1[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]

Joanna needs a book to prop up a table leg. There are 8 Math books, 4 science books, and 5 history books. She
randomly selects a book, removing it from the shelf, and then selects another book. What is the probability that
Joanna selected two math books?
Answer:22% or 64/289
Step-by-step explanation: you take 8/17 which is math books over the total of books and multiply it together. simplify into a percent (if thats allowed)
8/17 x 8/17 = 64/289

Answer:
1395 ft²
Step-by-step explanation:
The total area of the green surfaces
= 15² × 5
= 1125 ft²
The area of each triangular surfaces
= 15 × 9 ÷ 2
= 67.5 ft²
The total area of triangular surfaces
= 67.5 × 4
= 270 ft²
The total area of the figure
= 1125 + 270
= 1395 ft²

.Use the following data set to answer the questions below.
8, 15, 17, 19, 21, 82
1. What is the mean?
2. What is the median?
3. Is there an outlier? If so, what is the outlier?
4. What is the mean without the outlier?
Answer:
1. The mean is 162 divided 6 = 27 which is like 27 x 6 = 162
2. So since 17 and 19 are in the middle of course you will have to add that together 17 + 19 = 36 but then you MUST ALWAYS divide by 2 which 36 divided by 2 = 18
3. Yes there is a outlier. and i believe it's 82
4. i believe the mean will be 80 but then divided by 5 will be 16
hope this helped :D
Step-by-step explanation:
name three of the main powers of the executive branch
The executive branch is headed by the president, whose constitutional responsibilities include serving as commander in chief of the armed forces; negotiating treaties; appointing federal judges (including the members of the Supreme Court), ambassadors, and cabinet officials; and acting as head of state.
This will help you.
They:
-Take care that the laws be faithfully executed
-Serve as commander in chief of the armed forces
-Carries out and enforces laws
The President of the United States is the head of the executive branch. It includes the president, vice president, the Cabinet, executive departments, independent agencies, and other boards, commissions, and committees.
Hope I was able to help. :DDD
What is the domain? Is it (-4,3)
Yes I think you are correct. The domain appears to be the set of x values such that -4 < x < 3 meaning that x is between -4 and 3, excluding each endpoint. In interval notation, that translates to (-4, 3). This of course assumes that we have two vertical asymptotes bookending the left and right sides of the curve, and these vertical asymptotes are at x = -4 and x = 3. If the curve extends beyond these boundaries, then the domain would instead be the set of all real numbers.
Frederick's salary varies directly with the hours he works. Last week I earned $ 328.30 and worked 33.5 hours. If he works 35 hours this week, what will be his salary from him?
Answer:
His salary will be of $343.
Step-by-step explanation:
Frederick's salary varies directly with the hours he works.
This means that this question can be solved by proportions, using a rule of three.
We have that:
For 33.5 hours, he earned $328.30. How much he earns for 35 hours?
33.5 hours - $328.30
35 hours - $x
Applying cross multiplication:
[tex]33.5x = 328.30*35[/tex]
[tex]x = \frac{328.30*35}{33.5}[/tex]
[tex]x = 343[/tex]
His salary will be of $343.

Answer:
x = 32y = 51Step-by-step explanation:
Angle U = angle N = 180° -142° -24° = 14°
The expression for angle U tells us the value of x.
2x -50 = 14
x -25 = 7 . . . . . divide by 2
x = 32 . . . . . . . .add 25
__
The measure of side SU is the same as that for side PN.
13 = (2x -y)
y = 2x -13 = 2(32) -13 . . . . solve for y, substitute for x
y = 51

A picture has a height that is 2 times it’s width . It is to be enlarged to an area of 128 in 2
What will the dimensions of the enlargement be , if the equation to represent its area 2x 2 = 128
9514 1404 393
Answer:
8 in by 16 in
Step-by-step explanation:
In your equation, we presume that x represents the width. Solving for x, we have ...
2x² = 128 . . . . . . given equation
x² = 64 . . . . . . . . divide by 2
x = √64 = 8 . . . . square root
The enlargement will be 8 inches by 16 inches.

Using the human species as an example, explain what is meant by a variation of traits.
Answer:
Every gene has many types of gene variants, which are called alleles. These alleles help the body prouperly code different types of variants. Humans have many different traits in their body, and that is how we have so many features. Genes are stored in chromosomes.
Answer:
Human variability, or human variation, is the range of possible values for any characteristic, physical or mental, of human beings. As the human species exhibits sexual dimorphism, many traits show significant variation not just between populations but also between the sexes.
