Answer:
(35,0)
Step-by-step explanation:
Consider the diagram below, the starting point is given as A and the finish point given as C.
Using similar right-angle triangle, we have that:

Therefore to find the point where Derek stops at C, we first determine the distance |AC|
|AC|=7+28=35
The Coordinates at C where Derek stops is (35,0)
This can be solve by cancel of units
Snice red/ bkue = 5/2
And bkue/ green = 3/ 5
So red/ green = (red/ bkue) x( blue/ green)
Red/ green = (5/ 2) x (3/ 5)
Red / green = 3 /2
So the ratio of red is to green is 3: 2
Answer:
Number of carnations = 6
Step-by-step explanation:
Let the number of carnations school band buys from florist be x.
Cost of each carnation = $0.50
Total cost for x number of carnations = $0.50x
Also , delivery cost = $15
So, total cost on buying x number of carnations from florist = 0.50x + 15
Now,
School band sells carnations at a price of $3 each.
Total revenue they get get after selling x number of carnations = $3x
We need to find that , when will the cost of the carnations be equal to the revenue from selling them.
i.e 3x = 0.50x + 15
or 3x - 0.50x = 15
or 2.50x = 15
or x = 
or x = 6
so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue
