What is the value of k?
9514 1404 393
Answer:
k = 10
Step-by-step explanation:
The useful shortcut* here is that the external angle is equal to the sum of the remote internal angles.
115° = (4k+5)° +(6k+10)°
100° = 10k° . . . . . . collect terms, subtract 15°
k = 10 . . . . . . . . . . divide by 10°
_____
* I call it a shortcut because you can get there from the relations ...
the sum of angles in a triangle is 180°a linear pair has a sum of 180°If we call the internal angles X, Y, and Z, then we have ...
X + Y + Z = 180° . . . triangle sum relation
Y + 115° = 180° . . . . . linear pair relation
Equating the expressions for 180° gives ...
X + Y + Z = Y + 115°
X + Z = 115° . . . . . . . . . subtract Y from both sides
The diameter of a circular mirror is 20 inches what is the area of the mirror? use 3.14?
Answer:
20/2 = 10
10 squared is 100 (10 x 10)
100 x (pi) = 314.159265359
But if we were to use 3.14 it would be 314

ONE HUNDRED POINTS PLEASE BE HONEST.
Answer:
12.207
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are legs of the right triangle, c is the hypotenuse.
The hypotenuse squared is equal to the square root of (7^2 + 10^2).
The square root of 149 is around 12.207.
You cannot simplify the square root of 149 so if the question wants it in radical form just input square root of 149.
Angle W is congruent to angle Z
the measure of angle W is 5x + 10
The measure of angle Z is 55 degrees
Answer:
x = 9
Step-by-step explanation:
If the question is find x:
5x + 10 = 55
5x = 45
x = 9

Find the measure of the indicated angle x
Answer:
36°
Step-by-step explanation:
all the interior angles of a triangle add up to 180°
78 + 66 = 144
180 - 144 = 36°
Answer:
sum of all the sides of a triangle= 180° 78°+66°+x = 180° x = 180° - (78° + 66°) = 180° - 144° = 36° x = 36°Ans. = the value of x is 36°.Whats the answer to this???

Step-by-step explanation:
A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms
Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers
Answer:
As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.
Step-by-step explanation:
A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

Which set of side lengths can be used to construct a triangle?
А
55 inches, 110 inches, 45 inches
B
45 inches, 45 inches, 90 inches
C
100 inches, 45 inches, 35 inches
D
75 inches, 55 inches, 45 inches
9514 1404 393
Answer:
D 75 inches, 55 inches, 45 inches
Step-by-step explanation:
The sum of the two shortest sides must exceed the length of the longest side. This is only the case for choice D.
A. 45+55 < 110
B. 45+45 = 90 . . . . needs to be greater, not equal
C. 35+45 < 100
D. 45+55 > 75 . . . . will form an obtuse triangle

Sharon is painting her house. she needs 5
gallons of brown paint for every 7 gallons of white paint. How many gallons of white paint does she need if she already bought 14 gallons of brown paint?
A. 10 gallons
B. 19.6 gallons
C. 16 gallons
D. 25 gallons
Answer:
19.6, B
Step-by-step explanation:
To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.
We are given this equation.
5 gallons of brown paint = 7 gallons of white paint
Divide both sides by 5.
1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint
Now, using this, substitute 14 into the left side.
14 gallons of brown paint = 1.4 * 14 gallons of white paint
14 gallons of brown paint = 19.6 gallons of white paint
Thus, the answer is B, 19.6 gallons
Which set of ordered pairs is a function? {(1,1),(2, 2), (3, 3), (4,4), (5,5)} {(0,0),(1,1),(1, -1),(4,2),(4, -2)} {(2,1),(2,2).(2,3),(2,4),(2,5)} {(1,5).(2.4),(3,3).(2, 2), (1,1)
[tex] \underline{ \underline{ \large{ \red{ \tt{✧ E\: X \: P \: L \: A \: N \: A \: T\: I \:O\: N}}}}} : [/tex]
❀ Here, We are given relation from A to B [ Suppose ] & We have to identify whether they are function or not from the relation A to B.
{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 )}⇢ This is a function from A to B because every element of Set A has unique image in set B.
{( 0,0 ) , ( 1 , 1 ) , ( 1 , -1 ) , ( 4 , 2 ) , ( 4 , -2 ) }⇢ This is not a function because two of the elements of Set A ( 1 & 4 ) are associated to elements -1 , 1 & 2 , -2 respectively of Set B
{ ( 2 , 1 ) , (2 , 2 ) , (2 , 3 ) , (2 , 4 ) , (2 , 5 )⇢ This is not a function because the element of Set A ( 2 ) is associated to all the elements of Set B.
{ ( 1 , 5 ) , ( 2 , 4 ) , ( 3 , 3 ) , (2 , 2 ) , ( 1 , 1 )⇢ This is not a function because the elements of Set A ( 1 & 2 ) are associated to elements ( 5 , 1 & 4 , 2 ) of Set B respectively.
[tex] \boxed{ \boxed{ \large{ \purple{ \tt{A \: N \: S \: W \: E \: R: \{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 ) \} }}}}}[/tex]
♨ Q. What is function ? How can we identify whether the given relation is a function ?
⟶Function is a special type of relation. Function is the refinement of relation. In a relation from A to B , every element of Set A has only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.

Find the volume of the sphere need help
Answer:
36pi
Step-by-step explanation:
volume = (4/3) · π · r3
in this case r = 3
4/3 x pi x r^3
3 cubed = 27
27 x pi x 4/3
27 x 4/3 = 36
