The formula b=26a is used in New England to estimate the minimum furnace output, b, in BTU's, for a modern house with a square feet of flooring.

What is the minimum furnace output?

what is a?

HOW DO I FIND THESE QUESTIONS OUT?

b would be the minimum furnace output. It depends upon the house area, a.

"a" is in square feet.

You cannot come up with a numerical answer for b because they have not told you the area, a.

To find the minimum furnace output (b), you need to multiply the value of 'a' by 26.

- If you have the value of 'a', you can simply substitute it into the formula and calculate the value of 'b'. For example, if a = 1000 square feet, you can substitute it into the formula: b = 26 * 1000 = 26,000 BTU's

- If you have the value of 'b' and want to find 'a', you need to rearrange the formula. Divide both sides of the equation by 26: a = b / 26. For example, if b = 26,000 BTU's, you can substitute it into the rearranged formula: a = 26,000 / 26 = 1000 square feet.

To clarify the answers to your specific questions:

1. The minimum furnace output (b) is calculated by multiplying the value of 'a' by 26 using the formula b = 26a. The units for b are BTU's.

2. 'a' represents the square footage of the flooring of a modern house. It is used in the formula to estimate the minimum furnace output.

To find these answers, you need to have either the value of 'a' or 'b' given, or you can use the provided formula and substitute the known value to calculate the other variable.
