Answer:
A cross-section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross-section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross-section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
Step-by-step explanation:
the cross sections that are parallel and perpendicular will have the same measurements as the non-intersected sides. the last one will be a diagonal so the intersected edge is 6 and it creates a right triangle so it must be larger than 15 inches.
If you re-read your question, you will see that the answer you want is the one that includes 12 miles and 3 hours which is only choice A
Answer:
15
Step-by-step explanation:
The base would be 3*3, as it's a square. There are 4 triangles, and the area of each triangle is 1*3/2=1.5. 1.5*4+9=15.
Answer:
C. 120°
Step-by-step explanation:
m∠d = 150°
m∠ a = 90°
The sum of angles at a point add up to 360°
m∠b + m∠c +m∠e = 360° - (90° + 150°) = 120°
