The expanded form of a number is (6 * 1) + (2 x 0.1) + (7 x 0.01). How should the number be written in word form?
six and twenty-seven
six and twenty-seven tenths
six and twenty-seven hundredths
six and twenty-seven thousandths

answer:

6.27

Step-by-step explanation:

6 * 1 = 6, 2 * .1 = .2, and 7 * .01 = .07. 6 + .2 + .07 = 6.27

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
