72 minutes. First convert the height of the pool to inches by multiplying the height in feet by 12 which equals 36. Next multiply that by 2 because the pool is draining at -1/2 inches per minute, not -1 inch per minute.
The manager can do both but if he does 10 he will have 25 groups but if he does 5 he will have 50 groups so the simple way is 10 so he will have 25 groups
Wouldnt that be zero cuz they used more then they started of with?
All are congruent. Congruent means identical in size or shape. the different markings on the two shapes show that they are congruent. I can’t fully see number 10 so I can’t say it that one is or not
