If there is a triangle with Sid a and b then sina b/✓a2+b2and seven=✓a2+b2/a
Answer:
This depends on the price of how much the tickets cost in total so if the 10 tickets cost $10 dollars then the unit price would be $1
Step-by-step explanation:
You need to divide the total number by the number 10 and then that would be your unit price.
Answer:
d = 
Step-by-step explanation:
The distance formula is d = 
Plug in the points.
d = 
Solve
d = 
Simplify by separating 18 into 9x2
d = 
Take the square root of 9 to finish simplifying
d = 
Sure, here is how I broke it down. The bird is flying a constant X miles per hour with a wind speed of Y miles per hour. So, there are two equations that you use to solve. Here they are:
X+Y=12
X-Y=4
Now, you have to use substitution or elimination to solve (I will use elimination). To use elimination, you simply add both equations together to get:
2X=16
Solve for X by dividing by 2.
X=8. We already established that X is the speed of the bird. Plug X back into either of the equations to find the windspeed.
(8)+Y=12
Subtract 8 from both sides.
Y=4. We already established that Y is the windspeed.
So, the speed of the bird (X) is 8mph and the speed of the wind (Y) is 4mph.
Hope this helped!!
Answer:
X = -4
Step-by-step explanation:
-2 times -4 is 8. 8 - 3 is 5.
