A^2+b^2 = c^2, so 4^2 + 18^2 = 340, the square root of 340 = 18.43909. Rounded to the nearest tenth, the answer is 18.4
28.26=4 * base base= 28.26/4=7.065
50 tens would be 50 x 10 = 500

Which option is true?
A coordinate point is of the form; 
So, we have to substitute the x and y values in the given equation.
A. For (12,0)
and 
becomes



<em>This is true</em>
B. For (0,12)
and 
becomes



<em>This is false</em>
C. For (3,-1)
and 
becomes

<em>This is true</em>
<em></em>
<em>Hence, (12,0)
, (3,-1) and (0,-4/3) are true values of the equation</em>
Answer:
$75
Step-by-step explanation:
<h3>Steps to determining the answer</h3>
- Determine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week.
- Multiply the answer gotten from one above by the price of the ticket
20 - 14 = 6
6 students would pay in the second week
6 x $12.50 = $75
The teacher would collect $75 in the second week
