Answer:
- 2 trees ($200 from either service)
- c=100+50t
- c=80+60t
Step-by-step explanation:
It can work well to solve problems like this by considering how many times the difference in per-tree costs it takes to make up the difference in one-time costs.
Here the difference of one-time costs is $20, and the difference in per-tree costs is $10, so it takes the pruning of 2 trees for the per-tree cost difference to equal the one-time cost difference (2×10 = 20).
___
The cost equations are ...
cost = (one-time cost) + (per tree cost) × (number of trees)
c = 100 + 50t . . . . . company A
c = 80 + 60t . . . . . . company B
_____
If you use these equations to solve the problem, you want to find t such that the two costs are equal:
100 +50t = 80 +60t
(100 -80) = t(60 -50) . . . . . . . subtract 80+50t, factor out t
(100 -80)/(60 -50) = t . . . . . . . looks a lot like the verbal description above
The difference in fixed price divided by the difference in per-tree cost) is the number of trees required to make costs equal.
Answer:The side opposite to the obtuse angle in a obtuse triangle is the largest side of that triangle.
Step-by-step explanation:
- The obtuse angle is an angle that is more than 90° and less than 180°.
- Any triangle cannot have two angles equal to or more than 90° .
So if a triangle has an obtuse angle then it will be the only obtuse angle in the triangle, rest of the other two angles must be smaller than that.
Also, we know that the side opposite to the lager angle is larger.
Therefore, the side opposite to the obtuse angle in a obtuse triangle is the largest side of that triangle.
