Given is an Isosceles triangle LMN with vertices L(0, 1), M(3, 5), and N(6,1).
It says to find the slope of the side LN.
We know the formula for slope of any two points is given as follows :-
Slope of LN = 0 means " LN is a horizontal line".
Answer:
integers are closed under division
Step-by-step explanation:
Integers are not closed under division.Let us consider two integers i and j.
Then need not necessarily be an integer. For example, 2 and 3 are integers but is not an integer. So the first option , namely, integers are closed under division is not true.
On the other hand, the remaining three options given are correct.
Let the required amount of the second alloy be x, then
0.15 x 20 + 0.1x = 0.12(20 + x)
3 + 0.1x = 2.4 + 0.12x
0.12x - 0.1x = 3 - 2.4
0.02x = 0.6
x = 0.6/0.02 = 30
Therefore, to make a 12% mixture, 30 pounds of the secon mixture should be added.
