A young mother is attempting to clean the house while her 2 children, ages 5 and 2, play in the living room. The older child begins feeding lego bricks to the younger at a constant rate. Below is a chart of how many bricks remain yet to be consumed after a given number of minutes. Time (minutes): 4 6 11 17

Bricks remaining: 75 69 54 36

How many lego bricks were there before the un-attentive mother began cleaning?

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
