Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x? x = 8 x = 10 x = 13 x = 18
Answer:
x = 10
Step-by-step explanation:
Each exterior angle of a regular decagon has a measure of (3x + 6)°. What is the value of x?
The sum of the exterior angles of a decagon = 360°
Decagon = 10 sides
Each angle in a decagon = 360/10
= 36°
We are told that:
Each exterior angle of a regular decagon has a measure of (3x + 6)°.
Hence,
(3x + 6)° = 36°
Collect like terms
3x = 36 - 6
3x = 30
x = 30/3
x = 10
Answer: The person above me is correct! It is B. X=10 I got a 100% on the test! Edge2021

Distance: Jack and Jill start from the same point and walk in'opposite directions. Jack
walks 2 kmh faster than Jill. After 3 hours they are 30 kilometers apart. How fast did
each walk?
Answer:
t = 6 km/hour
And, J would be 4 km per hour
Step-by-step explanation:
Let us assume the speed of Tom be T
And, the Speed of Jim be J
Given that
T - J = 2 km /hr ...........(i)
After 3 hours distance between them = 30 km
As they are walking in the opposite direction
Thus,
Net speed =T + J
L ÷ (T+J) = 3
30 ÷ (T+J) = 3
T +J =10 ..............(2)
After solving these two equations
2T = 12
t = 6 km/hour
And, J would be 4 km per hour

What is the surface area of the triangular prism shown?
A.32 square centimeters
B.120 square centimeters
C.184 square centimeters
D.1,560 square centimeters
NO LINKS TO WEBSITES!!!!!!!!
Answer:
C. 184 square centimeters
Step-by-step explanation:
4 x 6 = 24
there are 2 of them so you leave it the same
5 x 10 = 50
there are 2 of them so
50 x 2 = 100
6 x 10 = 60
24 + 100 + 60 = 184
184 square centimeters

Line BC is tangent to the circle centered at A. Find the measure of angle BCA. Explain or show your reasoning.
Answer:
[tex] m\angle BCA= 33\degree[/tex]
Step-by-step explanation:
[tex] In\: \odot A[/tex] BC is tangent to the circle at point B.
Therefore, by tangent-radius theorem:
[tex] \therefore AB\perp BC[/tex]
[tex] \therefore \angle ABC = 90\degree [/tex]
[tex] In\: \triangle ABC, [/tex]
[tex] m\angle ABC +m\angle BAC +m\angle BCA= 180\degree [/tex]
[tex] 90\degree+57\degree +m\angle BCA= 180\degree [/tex]
[tex] 147\degree +m\angle BCA= 180\degree [/tex]
[tex] m\angle BCA= 180\degree - 147\degree[/tex]
[tex] m\angle BCA= 33\degree[/tex]

Answer:
12,300
Step-by-step explanation:
I'll right this as a function to make it easier on me.
f(x) = 7500(1 + 0.8)^x
f(2) = 7500(1 + 0.8)^2
f(2) = 7500(1 + 0.64)
f(2) = 7500(1.64)
f(2) = 12300
Answer:
$8700
Step-by-step explanation:
0.08 x 2 yrs = 0.16
7500 x 0.16 =1200
7500 + 1200 = 8700

Find the volume of the sphere. Either enter an exact answer in terms of π πpi or use 3.14 3.143, point, 14 for π πpi and round your final answer to the nearest hundredth.
radius is 8
Answer:
Solution :-Volume of sphere = 4/3 πr³
Volume = 4/3 × 3.14 × 8³
Volume = 4/3 × 3.14 × 512
Volume = 4/3 × 1607.68
Volume = 2143 in³
[tex] \\ [/tex]
Radius of the sphere is 8 units.
To Find:-The volume of the sphere.
Solution:-We know, volume of sphere is [tex] \frac{4}{3} [/tex]πr³
So, volume of sphere = [tex] \frac{4}{3} [/tex] × 3.14 × 8 × 8 × 8
= [tex] \frac{6430.72}{3} [/tex]
= 2143.6

Insert three rational and three irrationall
no. between 150 and
and 0
160
Answer:
Step-by-step explanation:
Rational numbers:
(150+160)/2 = 310/2 = 155
(150+155)/2 = 305/2= 152.5
(155 +160)/2 = 315/2= 157.5
155, 152.5 , 157.5 are rational numbers between 150 and 160
Irrational numbers:
Irrational numbers are numbers that are non terminating and non repeating numbers
155.502003000.....
155.202002000......
156.3120578.......
Answer:
Required Answer :-1st rational number
= a + b/2
= 150 + 160/2
= 310/2 (1)
2nd rational number
Middle term of 150 and 160 is 155
= 150 + 155/2
= 305/2
3rd rational number
= 160 + 155/2
= 315/2
