If the slopes of the 2 lines are equal then they are parallel.
If m1m2 = -1 (where m1 and m2 are the slopes of the 2 lines) then they are perpendicular.
If the 2 slopes do not match either the first or second conditions then they are neither parallel or perpendicular.
Answer:
I think it's 5(9)+20
Step-by-step explanation:
5(9+4) can be expanded to get 5(9)+5(4). And 5(4)=20
When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99.
For example, 4/11 = 36/99 = 0.36 with bar notation over 36.
Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6.
You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal.
Example: 2/4 = 0.5
Strike is the way that
the noise made on the hour it’s described. Each hour corresponds to a
specific strike, 1 has 1 strike, 2 have 2 strikes, 3 have 3 strikes, and so on.
The solution would be like
this for this specific problem:
1 + 2 +3 + 4 + 5 + 6 + 7 + 8 + 9 +
10 + 11 + 12 = 78 strikes for a 12 hours
78 * 2 = 156 (since a day has 24
hours)
So it
will strike 156 times per day. I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
1 yard = 3 feet
Then the to find the number of feet in a number of yards use the conversion factor, 1 = 3 feet / yard
number of feet = number of yards * 3 feet/yard
If the number of feet is f and the number of yards is y, you can write the expression in this way:
f = 3y
