HELP PL! I WILL GIVE YOU BRAINLIEST PLS HELP! Between 11 P. M. and 8:20 A. M., the water level in a swimming pool decreased by 4/15 inches. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
