QUESTION 26 In an a-c circuit, inductive reactance XL is directly proportional to frequency f. If XL - 400 ohms when f - 50 hertz, find XL when f - 60 hertz.

Which statement most accurately describe why the division property of exponents does not apply to the expression (-8)^2/(-3)^4

Graph red beads cost $1 an ounce and gold beads cost $3 an ounce. juanita wants to purchase a 12-ounce mixture of red and gold beads that she can sell for $2 an ounce. the solution of the system shows the number of beads needed for juanita to break even. x + y = 12, x + 3y = 24 how many ounces of red beads will juanita buy to break even? how many ounces of gold beads will she buy?

Solve the system of equations y= 3/2 - 1, -x+ y =-3
