Answer:
<A = 30
<B = 150
Step-by-step explanation:
- cos<A = AK / AB
- AK = 4
- AB = 8
- Cos<A = 4/8
- Cos<A = 1/2
- A = Cos-1(0.5)
- A = 30 degrees
- Since BC and and AD are parallel, the interior angles of <A and <B sre supplementary.
- <A + <B = 180
- 30 + <B = 180
- <B = 180 - 30
- <B = 150
3 is the coefficient because n is the variable
The answer is 1/3 chances, There are 12 tables in total, 4 red and 8 blue. You can Render that down to 1 red and 2 blue, now there are 3 tables and only 1 is red, therefore the answer is 1/3 chance
I think it is B. and the amount that they each need to pay is $1.13
Answer:
The greatest common factor of this would be 3x^2y
Step-by-step explanation:
In order to find this, first find the greatest common factor of the coefficients. Since 3 goes in evenly to both 15 and -18, then we know that it is a common factor.
From there we need to find the number of x's. Since the first term only has 2 x's and the second has 3, we take the lowest number. (x^2)
And since the first term has 3 y's and the second has just 1, we take the lowest number (y).
