Answer:
1/216
Step-by-step explanation:
x^(-3)y^(-3)
(2)^(-3)=1/2^3=1/8
(3)^(-3)=1/3^3=1/27
(1/8)(1/27)=1/216
Answer:
Explanation:
The surface of a lake represents a <em>plane</em> because it extends in all directions at the same level. Imagine it as a quite surface, without imperfections, smooth and perfectly plane, it is a two-dimensional figure.
A fishing line that enters into the water, crossing the lake's surface, representes a <em>line, </em>which may be either perpendicular or leaned.
Thus the intersection of those two figures is a point.
A surface and a line that is not included in the plane and is not parallel to it will meet at a single point, which is what is represented by the situation stated.
Answer:
c 32 out of 80 were surveyed
30 divided by 22= 1.36
1.36 minutes for each page, to check 1.36x22= 29.92
1.36x100= 136 minutes.
Mary would need about 2 hours and 16 minutes to read a 100 page book.
The common denominator would be 18. So, 5/6 becomes 15/18 and 7/9 becomes 14/18
