Answer:
21sq
Step-by-step explanation:
multiply the l times the w which would be 3x7 and get 21.
Answer:
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
Step-by-step explanation:
In a triangle, the sum of all inside angles must be 180 degrees.
In this question:
The inside angles are: x, x + 50 and 180 - 3x.
Then
x + x + 50 + 180 - 3x = 180
2x - 3x = -50
x = 50
So
x degrees = 50 degrees.
x + 50 degrees = 50 + 50 = 100 degrees
(180 - 3x) degrees = (180 - 3*50) = 30 degrees.
I believe the answer is C: how close a measurement comes to the expected value
Answer:
DISCLAIMER:I'M NOT REALLY GOOD AT MATH
Surface area=¶r squared.
¶=3.14
Radius=D/2
=10/2
5
therefore,3.14×5×5
=78.5
7^-2= 1/7^2
= 1/14
= 0.071429
