Answer:
Angle 3 = 115°
Angle 4 = 22°
Angle 5 = 43°
Angle 6 = 115°
Step-by-step explanation:
These two triangles are congruent by SSS. It is given that two sides are congruent already, and by the reflexive property, they share a side and therefore have a third congruent side.
By CPCTC, all of their angles and sides are also congruent. And by the triangles angle sum theorem, side 3 and 6 must equal 115°
~~~
Have a nice day. Feel Free to ask questions. Spread the love.
Step-by-step explanation:
4 = 22⁰
5 = 43⁰
3 and 6 are same
kite total angles = 360⁰
so, to find 3 and 6, we need to subtract all angles we have and devide it with 2 because we need to find 2 angles...
360-22-22-43-43= 230
3 and 6 = 230 ÷ 2
= 115⁰

Solve the variable in the following equation: 5 + h = 11 − 2h
A. h = −1
B. h = 2
C. h = 5
D. h = 9
Answer: B. h = 2
Step-by-step explanation:
Given
5 + h = 11 - 2h
Add 2h on both sides
5 + h + 2h = 11 - 2h + 2h
5 + 3h = 11
Subtract 5 on both sides
5 + 3h - 5 = 11 - 5
3h = 6
Divide both sides by 3
3h / 3 = 6 / 3
h = 2
Hope this helps!! :)
Please let me know if you have any questions
Answer:
B) h=2
Step-by-step explanation:
5+h=11-2h
5+h-(-2h)=11
5+h+2h=11
5+3h=11
3h=11-5
3h=6
h=6/3
h=2

Answer: V= 100.48 m^3 or in terms of Pi V = 32 π m^3
Step-by-step explanation:
V = πr^2h
V = π(2)^2(8)
V = π(4)(8)
V = 100.48
or
V = π (4)(8)
V = 32 π m^3

A clerical worker takes 3 times as long to finish a job as it does an executive secretary. Working together, it takes them 4 hr to finish the job. How long would it take the clerical worker, working alone, to finish the job?
Answer:
8 hours
Step-by-step explanation:
In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)
Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.

+1x=+50
Answer:
x=50
Step-by-step explanation:
+1x=50
divide both sides by 1
x=50
Answer:
x = 50
Step-by-step explanation:
If you divide anything by one, it will remain the same.
To isolate the x variable, you need to divide both sides by 1.
+1x/1 = 50/1
x = 50

Question:
Find the area of the composite figure round to the nearest tenth
Answer:
360Step-by-step explanation:
(25 x 12) + (10 x 6)
round it 360 >>>>> 360 it is the same
Answer:
360
Step-by-step explanation:
Split the given figure up into two different rectangles. One of these rectangles will have the dimensions (12 and 25), while the other will have the dimensions (6 and 10) Find the area of each rectangle using the general formula ([tex]length * width = area[/tex]), then add the two areas up to find the total area of the figure.
12 * 25
= 300
6 * 10
= 60
300 + 60
= 360

An airline uses many different types of airplanes. Information regarding some of the airplanes is given in the table below. A 5-column table with 5 rows. Column 1 is labeled Plane with entries SkyBus 280, SkyBus 580, Grigson A-2, Grigson A-5, SkyDancer. Column 2 is labeled Number of seats with entries 120, 225, 70, 130, 350. Column 3 is labeled Seat width (inches) with entries 20.3, 20.6, 19.9, 20.5, 20.2. Column 4 is labeled Wi-fi with entries no, yes, no, yes, yes. Column 5 is labeled first-class seats question mark with entries no, yes, no, no, yes. Which of the variables is a continuous variable? number of seats seat width Wi-Fi first-class
Answer:
b took the test right now
Step-by-step explanation:
The required, seat width is the continuous variable in the given table.
What is continuity?Continuity is a mathematical concept that describes the smoothness of a function or a curve. A function is said to be continuous if there are no abrupt changes or breaks in the values it takes as the input varies. More formally, a function f(x) is continuous at a point x = a if the limit of f(x) as x approaches a from both sides exists and is equal to f(a).
For example, a function that describes the temperature in a room as a function of time is continuous if there are no sudden changes or jumps in the temperature.
Here,
The number of seats is not a continuous variable because it can only take discrete values (such as 120, 225, etc.).
The Wi-Fi and first-class variables are not continuous either because they are categorical variables that can only take a limited number of values (yes or no).
The seat width variable, however, is a continuous variable because it can take on any value within a range of values (such as between 19.9 inches and 20.6 inches). Therefore, seat width is the continuous variable in the given table.

Which statement about the data is true
Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean.
Step-by-step explanation:
A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)
B is wrong, because the mean is exactly 0.5
C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.
