Answer:
You can use Pythagoras theorem to calculate x:
12² + 14² = x²
144 + 196 = x²
x² = 340
x = √340 ≈ 18,44
Answer:
F. 5:27
Step-by-step explanation:
4:20+67 minutes= 5:27
I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
There are 4! ways to sit the boys, and 4! ways to sit the girls.
Whether the boys sit to the left or the right of the girls don't matter, since it is a circular table AND rotations are not considered distinct arrangements.
So the total number of arrangements is the product of the two, namely n=4!4!. (note: (4!)^2 or (four factorial) squared.
Answer:
Slope of given line = and slope of perpendicular line =
Step-by-step explanation:
We are given a line -9x - 4y = 5 .
We have to find the slope of a line parallel to this line and also a line perpendicular to this line.
Let the general equation be ax + by = c.
Then the slope of this line = =
The slope of a line perpendicular to a line is the negative inverse of the slope of the line. Using this concept,
Slope of line perpendicular to the given line = =
