19) max bought a new speed boat that cost of $33,000. the boat depreciates approximately 18% of its value each year. write an equation to model the decay value of the speed boat. a) a = 33,0000.18t b) a = 33,0001.82t c) a = 33,0000.82/t d) a = 33,000(0.82)t

We must write an equation of the exponential type in the following way:
 y = A * (b) ^ t
 Where,
 A: initial amount
 b: decrease rate
 t: time
 Substituting values we have:}
 y = 33000 * (0.82) ^ t
 
 D) A = 33,000 (0.82) ^ t

Fraction of the scouts are square dancing is .

Step-by-step explanation:

Each pair  is one Girl Scout and one Boy Scout.

So,  to  the final fraction ( of the pairs) we are going to get 1/2 from the fraction of girls and 1/2 from the fraction of boys.  

Girls=

Boys=

To get the fraction of the scouts that are square dancing,  we have to add the fraction of girls ,  with the fraction of boys.  

=

=

=

=

This means that  from 30 scouts ,  19 are dancing.
