If a toaster produces 12ohms of resistance in a 120-volt circuit. What is the amount of current in the circuit

10 amps.

Step-by-step explanation:

According to Ohm's Law, V=IR, and, dividing both sides by R, we have , where V is the amount of volts, R is the amount of resistance, and I is the current in amps.

Plugging the values into the formula, we have .

Therefore, there is 10 amps of current in the circuit.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
