Ten thousand - 10,000
thousand literally just haves 1,000
if the twenty is before the three zeros, it would be 20,000 which is twenty thousand. its the same with other numbers. its super simple!
Answer: Diego buys about 3 pounds of blueberries, b
Step-by-step explanation: Lets write an equation to solve for b, how many pounds of blueberries he bought.
4.99b=14.95
Solve:
4.99b divided by 4.99 = 14.95 divided by 4.99
b = 3
13 and 14 because 13 squared is 169 and 14 squared is 197
Answer:
slope is -4/1 so
Step-by-step explanation:
Given:
Nana has a water purifier that filters of the contaminants each hour.
Water has contaminants =
To find:
The function that gives the remaining amount of contaminants in kilograms, C(t), t hours after Nana started purifying the water.
Solution:
Let C(t) be the remaining amount of contaminants in kilograms after t hours.
Initial amount of contaminants =
Decreasing rate is .
Using the exponential decay model:
where, is initial amount of contaminants, r is the decreasing rate and t is time in hours.
Substituting the values, we get
Therefore, the required function is .
