Volume of the spherical tank will be given by:
V=4/3πr³
thus the volume of the tank will be:
V=4/3×π×(10/2)³=523.59877756~523.6 ft³
Given that 523.6 ft³ can hold 358,000,000 BTUs of propane, the amount that 1 ft³ will be given by:
[total amount]/[total volume]
=358,000,000/523.6
=683,728.0367 BTUs/ft³
=684,000 BTUs/ft³ (in thousand)
Option A: is the equation.
Explanation:
Let x represents the number of hours per month the store is open.
It is given that the the monthly rent(expense) = $1200
Also, the employee salary for each hour(expense) = $120x
Thus, the total expense C(x) is
It is also given that the income per hour(revenue) is $200x
Thus, the revenue function R(x) is
The break - even point is given by
Total expense = Revenue
Thus, is the equation.
Hence, Option A is the correct answer.
Y = -7....this is a horizontal line. A line that is perpendicular to a horizontal line is a vertical line. A vertical line is represented by x = a number....with that number being the x coordinate of ur point (-3,-8)
therefore, ur perpendicular line is : x = -3
