PLEASE HELP There are 20 volunteers at a community park cleanup day. if three volunteers are choosing at random to lead cleanup crews, what is the probability that carla will lead the playground clean up, bill will lead the pond clean up and david will lead the picnic area clean up. (Probability)

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
