Answer:
im pretty sure its -3/2
Step-by-step explanation:
since you have to do rise over run and your falling 3 so its a negative 3 and you always run right so its run 2 so then its -3/2 if its not that sorry 
 
        
             
        
        
        
Answer:
15.59
Step-by-step explanation:
The answer is 15.59 because to find the area of an equilateral triangle, you need to multiply the height by the length. In this scenario, the length is 6, and we need to find the height. Since we know that all of the sides of the equilateral triangle are 6, we can put a line dividing the equilateral triangle exactly in half as our height. This will form 2 triangles, and each of them will have a length of 3, and a slant height of 6. They would also be right triangles. Now, with this information you can do pythageroum thereom to find the height:: 3^2 + h^2 = 6^2. So, h = √27. Now, to find the area of a triangle, you must multiply the length by the height and then divide by 2. So (6 • √27)/2 is equal to 15.5884572681, which rounded is equivalent to 15.59. So the answer is 15.59.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
c varies jointly with d and the square of g


where, k is constant of proportionality. 
Put the given value c = 30 when d = 15 and g = 2 and find out k 


 
 
If c = 6 and g = 8 then d = ? 



Hence, The value of d is 
 
        
             
        
        
        
Ok so we have 7:00 pm and she spends 12 more hours over. 
Now lets count up 12 hours
=19
You could also just do 7+12! :)
So therefore, she spend 19 hours had her friends house! :D
Hope this helps!
