Is rational. The value is 0.42857.
Step-by-step explanation:
If each interior angle of a regular polygon is 144 degrees. Find the number of sides in it.
Answer:
10
Step-by-step explanation:
In a polygon
interior angle + interior angle = 180°, thus
exterior angle = 180° - 144° = 36°
The sum of the exterior angles in a polygon = 360°, thus
number of sides = [tex]\frac{360}{36}[/tex] = 10
Answer:
10 sides
Step-by-step explanation:
A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440°.

3. ( did not know how to crop, please ignore this question! )
Thank you so much!
Answer:
See Explanation
Step-by-step explanation:
m = 46° (vertical angles)
j = 92° (vertical angles)
j + k + 46° = 180° (staright line angles)
92° + k + 46° = 180°
138° + k = 180°
k = 180° - 138°
k = 42°
n = 37° + 44° = 81°

To mail a package, UPS charges a $7 flat fee and $2 per pound. FedEx charges
a $5 flat fee and $3 per pound.
Answer:
The package where they charge the same must cost $2
Step-by-step explanation:
Given
UPS
[tex]Flat = \$7[/tex]
[tex]Additional = \$2/lb[/tex]
FedEx
[tex]Flat = \$5[/tex]
[tex]Additional = \$3/lb[/tex]
Required
What pound do both charges are the same
Represent the charges with x;
For UPS, it can be written as:
[tex]Charges = 7 +2x[/tex]
For FedEx:
It is:
[tex]Charges = 5 + 3x[/tex]
Equate these charges together
[tex]5 + 3x = 7 + 2x[/tex]
Collect Like Terms
[tex]3x - 2x = 7 - 5[/tex]
[tex]x = 2[/tex]
Hence, the package where they charge the same must cost $2

(4x+108) +(2x) =180
What is x? Help please
Answer:
x = 12
Step-by-step explanation:
For this problem, we can simply drop the parenthesis, combine like terms, and isolate x to find the value of x. Below is how to do this:
( 4x + 108 ) + ( 2x ) = 180
4x + 108 + 2x = 180
4x + 2x + 108 = 180
6x + 108 = 180
6x = 72
x = 12
Hence, the value of x is 12.

Calculate the distance between the points C=(-9, 9) and N=(-1,5) in the coordinate plane.
Round your answer to the nearest hundredth.
Answer:
8.94
Step-by-step explanation:
use distance formula
squareroot of (x2-x1)^2 +y2-y1)^2
sqrt (-9 - (-1))^2 +(9 - 5)^2
sqrt (-8)^2 + 4^2
sqrt 64 + 16
sqrt 80
factored becomes
4sqrt of 5 or 8.94427
rounded 8.94

At a track meet, the 3 members of a relay race ran a total distance of 3/8 of a mile. if each runner ran the same distance. how far did each person run?
Answer:
.125 of a mile
Step-by-step explanation:
If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.
Change the 3/8 to a decimal
3/8 = 0.375 of a mile
Since there were 3 runners divide the total distance by 3
0.375/3 = 0.125
Each runner ran 1/8 of a mile or 0.125 of a mile.
A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distance dd the weather balloon rise?
Answer:
The ballon rose a distance of 37 1/2 feet
Step-by-step explanation:
Here, we are interested in calculating the level of ascent of the weather balloon.
From the question, we are told that the ballon made a transition from below the sea to above the sea.
Now to calculate the total distance, we shall
be adding the distances below the sea and the distances above;
Mathematically, that would be;
18 feet + 19 1/2 feet = 37 1/2 feet
Solve 12 + 12a + 4a = -4
Answer:
a=-1
Step-by-step explanation:
we need to get a by itself
first combine like terms
12+16a=-4
now we need to get rid of the 12 so subtract it to other side
-16=16a
now divide 16 by -16 which gives you -1=a
