The diagonals of a rhombus are 8 and 10 . the area of the rhombus is 20 40 80
2 answers:
Answer:
40
Step-by-step explanation:
In a rhombus the two diagonals intersect perpendicularly. So you can see a rhombus as the union of two triangles whose base is one of the diagonals of the rhombus and whose height is the half of the other diagonal.
Therfor you can calculate the area of the rhombus calculating the area of the two triangles that are the same.
In this case the area of each triangle must be (if you take the 10-lenght-side as the basis of the triangles).
Hence the area of the rhombus is 40 because is the double of the area of each triangle.

Answer:
Average speed is 37.35 mi/h
Step-by-step explanation:
given data
leave = 34 minutes before
church distance = 12.0 miles
average speed first 17 minutes = 5.0 mi/h
solution
so we find Total distance travel in first 17 minutes = speed × time
Total distance travel in first 17 minutes = 5 ×
Total distance travel in first 17 minutes = 1.416 mi
and
Distance Remaining = 12 - 1.416 = 10.584 mi
Time Remaining = 34 - 17 min = 17 min
so
remaining distance Average speed =
Average speed =
Average speed is 37.35 mi/h
