The formula for the area of a rhombus is a = a equals startfraction one-half endfraction d 1 d 2.d1d2, where d1 and d2 are the lengths of the diagonals.

which are equivalent equations? select two correct answers.

d1 = 2ad2
d1 = d 1 equals startfraction 2 a over d 2 endfraction.
d2 = d 2 equals startfraction d 1 over d2 a endfraction.
d2 = d 2 equals startfraction 2 a over d 1 endfraction.
d2 = 2ad1

You coordinate volunteers for litter cleanup in local parks. your spreadsheet lists drivers and the number of seat belts in each driver’s car. the spreadsheet calculates the number of drivers (d) and the total number of seat belts (s). you want to know the maximum number of volunteers, besides drivers, that can be transported to the park in a single trip given that each person must have a seat belt of their own.
