Probably the last one
Use the equation for the area of a triangle 1/2(bxh)
Then multiply that number by 2 to get the area of the complete shape.
Answer:
The answer is 118.
Step-by-step explanation:
First we need to subtract the meal cost from average unit cost for each meal:

A restaurant profits 1.25$ for each meal. If we divide fixed cost to profit for each meal:

The restaurant have to sell 118 meals at least each day for the owner to break even
Given : supply voltage = 120V;60 Hz
Inductive Reactance
Ω
The inductive reactance is given by the formula,
, where L is inductance and
is given by formula, 
Apply this, we can say that, 
1. 1000 2. 0.001. hope this helps.
