The average boa constrictor is about 7 1/2 feet long. How many inches is this?
A 76
B 84
C 86
D 90
E 96

90 inches

Step-by-step explanation:

1 foot => 12 inches, so 7 1/2 feet => 7 1/2 x 12

i.e. (7 x 12) + (1/2 x 12) => 84 + 6 = 90

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
