the formula a = 46c gives the floor area a in square meters that can be wired using circuits

A.solves a = 46c for c
b. if a room is 322 square meter, how many circuits are required to wire this room?

A. a = 46c --> Divide off 46. c = a/46.

B. a = 322 square meters. a = 46c, so 322 = 46c. c = a/46, so c = 7. 7 circuits are required.

To solve the formula a = 46c for c, we need to isolate the variable c.

Step 1: Start with the formula a = 46c.
Step 2: Divide both sides of the equation by 46: a/46 = c.

So, the formula c = a/46 can be used to solve for c.

Now, to determine how many circuits are required to wire a room with an area of 322 square meters, we will substitute this value into the formula.

Step 1: Start with the formula c = a/46.
Step 2: Substitute a = 322 into the formula: c = 322/46.

Calculating the expression, we find:
c ≈ 7

Therefore, approximately 7 circuits are required to wire a room with an area of 322 square meters.

To solve for c in the equation a = 46c, we need to isolate c on one side of the equation.

Step 1: Start with the equation a = 46c.
Step 2: Divide both sides of the equation by 46 to isolate c.
a/46 = 46c/46
a/46 = c

So, the solution for c is c = a/46.

Now, let's move onto the second part of your question.

If a room has an area of 322 square meters, we need to find out how many circuits are required to wire this room using the given formula a = 46c.

Step 1: Substitute the value of a into the equation.
a = 322 (given)
c = a/46
c = 322/46

Step 2: Calculate the value of c.
c = 7

Therefore, to wire a room with an area of 322 square meters using circuits, you would require 7 circuits.
