a group of 3 teachers sell homecoming t- shirts. They sell 58 t- shirts for 12.50 each. If they split the amount of money evenly, how much did each teacher make?

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

At your job you're paid $50 per week plus $3 per sale at least how many saled do you need to make in order to have over $250

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
