In the sequence 1, 2, 4, 8, 16, 32, . . , each term after the first is twice the previous term. what is the sum of the 16th, 17th, and 18th terms in the sequence? 218 3(217) 7(216) 3(216) 7(215) next previous review review screen

229376

Step-by-step explanation:

So we can model the sequence of 1,2,4,8,16,32,... as where n = 1,2,3,...

n = 16th, 17th, 18th then the terms are

So the sum of the 3 terms is 32768 + 65536 + 131072 = 229376

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
