For what value of a will 8×103 be 40 times larger than a×102 ?(1 point)
1 answer
We can set up the equation 8×103 = 40(a×102). Simplifying the right side of the equation, we have 8×103 = 40×(a×102) = 40a×104. Therefore, the equation becomes 8×103 = 40a×104. We can divide both sides by 40 and by 104 to solve for a: a = (8×103)/(40×104). Simplifying the right side of the equation, we have a = 0.0025. Therefore, the value of a that will make 8×103 40 times larger than a×102 is 0.0025.
