Which of the following equations could be used to determine the volume of the large rectangular box?
OA.
y = (27:2 + 63.1 + 30) cubic units
OB. y = (27:2 + 30 cubic units
OC. y = (1512 + 8) cubic units
OD. y = (1212 +235 + 11) cubic units

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
