The formula b=29a is used to estimate the minimum furnance output B in btus for a modern house with the amount of square feet of flooring A
1. determine the minimum furnance output for a 2300 ft2 modern house
2. solve the formula A
1. B = 29 * 2300 = 66,700 BTUs.
2. B = 29A,
A = B/29.
To determine the minimum furnace output for a 2300 ft² modern house, we can use the given formula: b = 29a. Here, "a" represents the square footage of the flooring, and "b" represents the minimum furnace output in BTUs.
1. To find the minimum furnace output for the 2300 ft² modern house, substitute the value of "a" into the formula:
b = 29 * a
b = 29 * 2300
Now, we can calculate the minimum furnace output by multiplying 29 by 2300:
b = 66700 BTUs
Therefore, the minimum furnace output for a 2300 ft² modern house is 66700 BTUs.
2. To solve the formula A, we need to rearrange the equation to isolate "a":
b = 29a
Divide both sides of the equation by 29:
b / 29 = a
Now, the formula is solved for "a," where "b" represents the minimum furnace output and "a" represents the square footage of the flooring.
