Anna, Gina, and Ted divided up a box of post cards. Anna took one-fourth of the cards. Gina took half of what remained. Ted took
2 answers:
Answer:
16 cards
Step-by-step explanation:
We can use logic to find out how many cards were in the beginning.
If Ted took 6 cards, and Gina took half of what remained, then when Gina took cards, she had to choose from.
Now, Anna took of the cards, meaning that 12 is
of the amount of cards there originally were.
Hope this helped!

Answer:
Since the price is given by an exponential function, the decline in price is exponential.
The component will cost $36.8475 in three years.
Step-by-step explanation:
The equation for the price of a component has the following format:
In which P(t) is the price after t years, P(0) is the initial price, and r is the rate that the price decreases.
Since the price is given by an exponential function, the decline in price is exponential.
The price of a computer component is decreasing at a rate of 15% per year.
This means that
Component costs $60 today
So P(0) = 60. Then
What will it cost in three years?
This is P(3).
The component will cost $36.8475 in three years.
Answer:
a)
b) f(t=2015) = 264,034,317.7
Step-by-step explanation:
The rate of change in the number of hospital outpatient visits, in millions, is given by:
a) To find the function f(t) you integrate f(t):
To solve the integral you use:
Next, you replace in the integral:
Then, the function f(t) is:
The value of C' is deduced by the information of the exercise. For t=0 there were 264,034,000 outpatient visits.
Hence C' = 264,034,000
The function is:
b) For t = 2015 you have:
