A surveyor needs to measure the​ distance, AB, across the lake. Beginning at​ E, he locates the​ midpoint, C, of and the​ midpoint, D, of . He then measures . What is​ AB? In triangle ABE, point C is on line segment AE and point D is on line segment BE. Line segments BD and DE each have a tick mark. Line segments AC and CE each have two tick marks. Line segment CD is also shown and has length 60 meters. Part of this figure is above a lake. Line segment AB shows the width of the widest part of the lake. Line segment CD is at the left edge of the lake.

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.
