A metalworker has a metal alloy that is 30% copper and another aloy that is 75% copper. How many kilograms of each alloy should the metalworker combine to create 60 kg of a 66% copper alloy? The metalworker should use kilograms of the metal alloy that is 30% copper and kilograms of the metal alloy that is 75% copper.

step-by-step explanation:

when the daily mileage is greater than 40 miles, unlimited mileage plan will save you money. 40 miles is the break-even point.

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
