1. The picture shows a feeding trough that is shaped like a right prism. Surface A and B are identical trapezoids

(a) Label all the dimensions of one trapezoid face. What are the lengths of the 2 bases of the trapezoid? What is the height of each trapezoid face?

(b) Use the information from part b to answer, Surfaces A and B will be painted blue. What is the total area that will be painted blue? Show your work!

(c) The edges of the trapezoids need to be sanded. A piece of sandpaper advertises that it can sand up to 20 cm. Will one piece of sandpaper be enough to sand all the edges of trough? Explain

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

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
