1 point Find the slope m of the line  10 =

1 point Consider the figure below. Deloney and Jackson Streets meet at a 45° angle. A lot extends 70 yards along Jackson and 50 yards along Deloney. Find the length (in yd) of the back border. (Round your answer to two significant digits.) 

2 points In the mid-20th century, engineers constructed a series of canals to move irrigation water from water sources to farming communities throughout the western United States. The volume of water a canal can move is partially dependent on its cross-sectional area. Suppose a canal is trapezoidal, 35.0 ft across the top and 15.0 ft across the bottom, with a planned depth of water of 10.0 ft as shown in the figure. Find the cross-sectional area of the canal when it is full (in ft2). (Use the rules for working with measurements give your answer to the appropriate accuracy and/or precision.)

2 points Find the volume of the cylindrical silo (in ft3) with a hemispherical top shown in the figure below. (Round your answer using the rules for working with working with measurements.)
