Step-by-step explanation:
Can a regular polygon have an interior angle of 132 degrees?
Given:
The interior angle of a regular polygon is 132 degrees.
To find:
The given statement is possible or not.
Solution:
Let as assume the interior angle of a regular polygon with n vertices is 132 degrees.
Then, the exterior angles are
[tex]180^\circ-132^\circ=48^\circ[/tex]
We have, n vertices. So, the number of exterior angles is n.
Sum of all exterior angles = 48n degrees
We know that, sum of all exterior angles of a regular polygon is always 360 degrees.
[tex]48n=360[/tex]
[tex]n=\dfrac{360}{48}[/tex]
[tex]n=7.5[/tex]
Number of vertices is always a whole number. So, it cannot be a fraction value.
So, our assumption is wrong.
Therefore, a regular polygon cannot have an interior angle of 132 degrees.
At 5.45p.M .,lixin,khairul and Devil are at the starting point of a 1-km circular path. Lixin Takes 18 minutes to walk one round ,khairul needs 360 seconds to run 1 round ansd Devi cycles 2 rounds in 4 minutes .Find the time when all three of them will next meet
Answer:
[tex]Meeting\ Time = 6:03\ pm[/tex]
Step-by-step explanation:
Given
[tex]Start\ Time= 5:45pm[/tex]
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 360\ seconds/round[/tex]
[tex]Devi = 4minutes/2\ rounds[/tex]
Required
Determine their next meeting time
First, we need to get their unit rate in minutes per round
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 360\ seconds/round[/tex]
Convert 360 seconds to minutes
[tex]Khairul = \frac{360}{60} min/round[/tex]
[tex]Khairul = 6 min/round[/tex]
[tex]Devi = 4minutes/2\ rounds[/tex]
Divide by 2/2
[tex]Devi = 2mins/round[/tex]
So, we have:
[tex]Lixin = 18\ min/round[/tex]
[tex]Khairul = 6 min/round[/tex]
[tex]Devi = 2mins/round[/tex]
Next, is to determine the LCM of 18, 6 and 2
[tex]18=2 * 3 * 3[/tex]
[tex]6 = 2 * 3[/tex]
[tex]3 = 3[/tex]
Their LCM is:
[tex]LCM = 2 * 3 * 3[/tex]
[tex]LCM = 18[/tex]
This means that they will meet 18 minutes after their initial time of departure.
So:
[tex]Meeting\ Time = 5:45\ pm + 18\ minutes[/tex]
[tex]Meeting\ Time = 6:03\ pm[/tex]

Answer:
x = 4
y = -7 or (-7, 4)
Step-by-step explanation:
y = -2x + 1
4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it
4x + (-2x + 1) = 9 add like terms
2x + 1 = 9 subtract 1 from both sides
2x = 8 divide both sides by 2
x = 4 since y = -2x + 1 replace x with the value we found
y = (-2) × 4 + 1 = -7

what does ( 7.8 x 10 to the 3rd) x (1.0 x 10 to the 4th) equal?
Answer:
7.8 * 10^7
Step-by-step explanation:
Group coefficients together and exponents together to multiply numbers in scientific notation.
( 7.8 * 1 ) ( 10 ^3 * 10^4)
Multiply 7.8 times 1.
7.8 * (10^3 * 10^4)
Use the power rule a^m * a^n = a^(m+n) to combine exponents. So, add 3 and 4
7.8 * 10^7

An electrician charges $75 per hour on top of a set fee of $50 for every house call. Write an equation for C, in terms of t, representing the total cost of the electrician's services if the electrician spends t hours at the house working.
C=?
Please help
Answer:
C= 75t + 50
This is the equation to use.
The equation that represents the total cost for a house will be C = 75t + 50.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
An electrical expert charges $75 each hour on top of a set expense of $50 for each house call.
Let 't' be the number of hours and 'C' be the total cost of the service. Then the equation is given as,
C = 75t + 50
The condition that addresses the all-out cost for a house will be C = 75t + 50.

Total consumption of fruit juice in a particular country in 2006 was about 2.05 billion gallons. The population of that country in 2006 was 500 million. What was the average number of gallons of fruit juice consumed per person in the country in 2006?
Answer:
4.1 gallons per person
Step-by-step explanation:
The total consumption of fruit juice is 2.05 billion
The total population is 500 million
Therefore the average number of gallons fruit juice consumed per person can be calculated as follows
=total consumption/total population
= 2,050,000,000/500,000,000
= 4.1 gallons per person
Solve for x: -3x - 3 = - 12
Answer:
-3x-3=-12 +3
-3x=-9 ÷(-3)
x=3
Step-by-step explanation:
prove me wrong
Answer:
x = 3
Step-by-step explanation:
-3x - 3 = -12
+3 +3
-----------------------
-3x = -9
-3x/3 = -9/3
-----------------------
-x = -3; x = 3
Check Work:
-3(3) - 3 = -12
-9 - 3 = -12
-12 = -12 (true)
Go step by step to reduce the radical.
√ 128
√16 • √8
8 √2
8 √4 • √2
I think its 8×4√16
Explenation:
√128 = 11.3
√16×√8=6.3
8√2= 11.3
so i think you see the patern there and the answer should be 11.3 or 6.3
8√4×√2= 19
19÷2=9.5
9.5÷2=4.75
since 5 is too big to put in the equation and equal 128 then its 4.
To find the second one just do 4², which is 16
So yeah 8×4√16

Miranda mixed 34.5 fluid ounces of blue paint, 40.5 fluid ounces of red paint, and 2 fluid ounces of black paint to make purple paint. She poured the same amount of the purple paint into 14 jars. How much paint did she pour in each jar
Answer:
5.5
Step-by-step explanation:
Miranda mixes 34.5 fluid ounces of blue paint
40.5 fluid ounces of red paint.
2 fluid ounces of black paint to produce a purple paint
She pours this purple paint into 14 jars
Therefore the amount of paint in each jar can be calculated as follows
= 34.5 + 40.5 + 2
= 77/14
= 5.5 fluid ounces
Hence there are 5.5 fluid ounces of purple paint in each jar

Which of the following best describes the graph above?
OA. both a relation and a function
OB. function only
OC. neither a relation nor a function
OD. relation only
Answer:
The answer you are looking for is B) Function only.
Step-by-step explanation:
A function graph would mean that each x value corresponds to one y value, in a function multiple x values can have the same output but one x value cannot have more than one output.
A relative graph means each x value has their own unique output value and each x value (f(x)) has one output but cannot share that output with any other x value.
In this case x=5 which means it can only be a function.
