The product of a non-zero rational number and an irrational number is irrational.
Therefore C is the answer.
A, B, and D are all properties of rational numbers. Irrational numbers are ones that can not be written as a ratio, or fraction, using whole numbers. They are non-repeating, non-terminating numbers. Example would be pi.
First find the area of the triangle (on top) and then subtract the area of the circle (on bottom) since the triangle is Equilateral, you can assume that the height can be found by using the 30 60 90 angle relationship. To find the radius of the circle, divide the height by 2.
Because it is a quadrilateral, all 4 angles have to add up to 360 degrees.
Add the 3 known angle measures.
80+95+38=213
Then subtract from 360.
360-213=147
X=147 degrees
Answer:
35:25
Step-by-step explanation:
seventh and eighth to sixth
7th+8th : 6th
20+15 : 25
35:25
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5
It will take 5 hours.
