Step-by-step explanation:
Because a^m / a^n = a^(m-n),
we have 5³ / 5⁷ = 5^(3-7) = 5^(-4).
A plane consists of an infinite set of points.
A point's location on the coordinate plane is indicated by an ordered pair, (x, y).
Step-by-step explanation:
The undefined terms in geometry are points, lines and planes.
- A point's location on the coordinate plane is indicated by an ordered pair, (x, y). TRUE. In R², the ordered pairs (x,y) is used to defined the location of a point.
- The second statement is false because a point has no dimension.
- The third statement is also false because a line has only one dimension which is length.
- The fourth statement is not true because distance between two points must have a beginning and an end.
- A plane consists of an infinite set of points. TRUE .The plane is a home of infinitely many points.
Increased enrollment =9%
Last enrollment=3900
Current enrollment=9%of3900+3900
=9×3900/100+3900
=351+3900
=4451
Answer: 56 cards
Step-by-step explanation:
8 times 10 is 80 so we now have to find how much does his sister has so if she get 3 cards from each pack. So we multiply 3 times 8 which equals 24. So 80 minus 24 equals 56 cards.
