The Spitzleys are going to put a rectangular pool in their backyard. The cost of excavating the dirt (digging up the dirt and taking it away) is $4,200. If the hole that is dug has dimensions of 25 meters by 15 meters by 3 meters, what is the cost for the excavation per cubic meter? Round to the nearest hundredth if necessary

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

v = 1/3 a^2h
