a. define variables for the quantities that are changing (be specific).
We define variables:
t = time in second
d = distance traveled
The variables that are changing are t and d.
As the time increases, the distance decreases.
b. what does it mean to say bob walks at a constant speed of 9.3 feet per second?
It means that for every second that passes, Bob walks 9.3 feet.
c. consider the formula d = 4320 - 9.3t i. what does t represent? ii. what does 9.3t represent? iii. what does d represent?
For this case we have:
t = represents the time in seconds
9.3t = represents the distance traveled by Bob
d = represents the distance Bob must travel to get to the bus stop.
Answer:
Therefore all numbers that end with five and are greater than five are composite numbers. The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
Step-by-step explanation:
Answer:
15% × 7 = 1.05
32,000 - 1.05 = 31,998.95
31,998.95 ‐‐‐‐‐> 31,999
$31,999
(If you don't need to simplify, the answer would be $31,998.95, but I did it just incase you do)
Step-by-step explanation:
Answer:
11.5%
Step-by-step explanation:
Let the number of smokers before ban = 100
Decrease in 1st month = 3% , of 100 = 3
Smokers after 1st month = 100 - 3 = 97
Decrease in 2nd month = 2%, of 97 = 1.94
Smokers after 2nd month = 97 - 1.94 = 95.06
Decrease in 3rd month = 5%, of 95.06 = 4.75
Smokers after 3rd month = 95.06 - 4.75 = 90.31
Decrease in 4th month = 2%, of 90.31 = 1.80
Smokers after 4th month = 90.31 - 1.80 = 88.51
- Decrease in smokers after 4th month = (Decrease / old value) x 100
[ (100 - 88.51) / 100 ] x 100 = (11.49 / 100) x 100
= 11.5%
