0.666667 as a fraction is 2/3
.0008 is 1/10 of .08. .08 is 10 times the value of .008. We know this because each place value to the right of the decimal is represented by a 0 and if each place is 10 times the place to the left's value.

Answer:
The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.
The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.
Exponential growth involves a constant multiplicative rate of change.
Step-by-step explanation:
All that apply in the statements are as follows:
(a) The bottle was ½ full at 11:35 a.m. and doubled again after five minutes, which indicates that the bottle doubled at 11:40 am
(b) The bottle was ¼ full at 11:30 a.m. and doubled twice after 10 minutes. These means that the bottle was ½ full at 11:35 a.m. (i.e. five minutes ago the bottle was at ¼ full at 11:30 am, after five minutes, the which is was ½ full at 11:35 am but later became full at 11:40 am)
(c) Exponential growth involves a constant multiplicative rate of change (1.e. the rates of growth is twice every five minutes)
Answer:
let the number of calories from lunch be called L. As such, breakfast is then L + 128, and dinner is 2L - 400. We can then sum the three meals and equate it to the total caloric intake, the known value of 1932.
So: 1932 = L + L + 128 + 2L - 400 = 4L - 272.
Lunch = 551
Breakfast = 551 + 128 = 679
Dinner = 2*551 - 400 = 702
