The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Answer:
6 sides
Step-by-step explanation:
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles. How many sides does this polygon have?
Let us represent:
Sum of Exterior angle as x
Sum of Interior angle as y
Note that:
The sum of the exterior angles of a polygon = 180 - The sum of the interior angles
Hence,
The sum of the exterior angles of a polygon + The sum of the interior angles = 180
x + y = 180
The measure of one interior angle of a regular polygon is two times the measure of one of its exterior angles.
2x = y
Substituting
x + 2x = 180°
3x = 180°
x = 180/3
x = 60°
Solving for y
2x = y
2 × 60° = y
120° = y
Hence,
Sum of Exterior angle as x = 60°
Sum of Interior angle as y = 120°
The number of sides of a polygon is
360°÷ Sum of Exterior angles
= 360° ÷ 60
= 6 sides

The diameter of a circle is 2 kilometers. What is the radius?
Answer:
The radius of the circle is 1 kilometer.
Step-by-step explanation:
The radius of the circle is the length from the very center of the circle to any other point in the circle. To find the radius, you only have to divide the diameter in half, so 2 ÷ 2 = 1. Hope this helped!! :]

11. f = 180-(75+65)
f = 180 - 140
f = 40°
12. x = 62+51
x = 113
y = 180- 113
y = 67°
13. x = 360-(100+95+60)
x = 360 - 255

One morning the temperature is -28 degrees in Anchorage, Alaska, and +65 degrees in Miami, Florida. Which city is warmer in the morning and by how much? *
A. Miami is 37 degrees warmer than Anchorage.
B. Miami is 93 degrees warmer than Anchorage.
C. Anchorage is 37 degrees warmer than Miami.
D. Anchorage is 93 degrees warmer than Miami.
Answer:
B. Miami is 93 degrees warmer than Anchorage.
Step-by-step explanation:
Miami-Anchorage is equal to 65-(-28) which is equal to 65+28 which is equal to 93. Thus, Miami is warmer by 93 degrees.

WOULD APPRECIATE A LOT
Answer:
d = w + 3 (first equation)
2d = 2w + 3 (second equation).
The second equation is equivalent to the first one.
In other words, two equations carry the same information as the first one, not more.
In the language of linear algebra, the system is dependent
What is the true solution to the equation below?
2 In eln2x - In eln 10x = In 30
X = 30
X= 75
X = 150
X=300
Answer:
x = 75 hope this helped
Step-by-step explanation:
The true solution to the equation is,
⇒ x = 75
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
Now, We can simply as;
⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]
⇒ 2 ln 2x - ln 10x = ln 30
⇒ ln (2x)² - ln 10x = ln 30
⇒ ln (2x)² / 10x = ln 30
⇒ 4x² / 10x = 30
⇒ 4x = 300
⇒ x = 75
Thus, The true solution to the equation is,
⇒ x = 75

What is the area of the rhombus (figure only show one part of the diagonals)
Answer:
60 cm^2 (dark blue)
Step-by-step explanation:
Since a rhombus's diagonal bisect each other, the diagonal's full length is 10 and 12. From there the area is 10*12 / 2 which is 60
The height of a football after it's been kicked from the top of a hill is h=2(-2-4t)(2t-5) where h is height and t is time in seconds how long was football in the air?
Answer:
2.5 seconds.
Step-by-step explanation:
When the football reaches the ground h = 0, so:
2(-2 - 4t)(2t - 5) = 0
so either -2 - 4t = 0 or 2t - 5 = 0
so -4t = 2 or 2t = 5
t = -1/2 , t = 5/2 = 2.5 seconds.
WE ignore the negative t , so
Time that the ball was in the air = 2.5 seconds.
Taylor has $20 to spend on school supplies. A pack of
colored pencils is $2.75. Taylor writes the inequality
2.75p < 20, where p is the number of packs of colored
pencils, taldetermine how many packs she can buy.
How many packs can she buy?
Answer:
7 packs
Step-by-step explanation:
2.75p < 20
Divide both sides by 2.75
2.75p/2.75 < 20/2.76
Simplify
p = 7.27 (27 repeating)
Round
p = 7

In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
