John, Paul, and George gather aluminum and tin cans to exchanges for money at the local recycling plant. One day, the three men

decided to combine their findings for the day. John collected 3.25 pounds of cans, Paul collected 6 1/3 pounds of cans, and George managed to collect the most with 11 1/6 pounds of cans. What percent of the total amount of cans did George collect? Round your answer to the nearest percent.

To find the percent of the total that George collected, you need to create a ratio with the number of pounds George collected compared to the number of total pounds that were collected.

You will then divide these to find the part (decimal) that George collected. You can convert the decimal to a percent.

3 1/4+6 1/3+11 1/6 = 20 3/4 total pounds of cans.

11 1/6 George
20 3/4 total

11 1/6÷20 3/4 = 0.538
0.538 is approximately 54%.

George collected proximately 54% of the total amount of cans.

The value of a $3000 computer decreases about 30% each year. write a function for the computers value V(t)
den301095 [7]

Answer:

Function for given situation is : V(t)=3000(0.70)^t

Value of computer after 4 years = $720.3.

Step-by-step explanation:

Given that the value of a $3000 computer decreases about 30% each year. Now we need to write a function for the computers value V(t). then we need to find about how much will the computer be worth in 4 years.

It clearly says that value decreases so that means function represents decay.

For decay we use formula:

A=P(1-r)^t

where P=initial value = $3000,

r= rate of decrease =30% = 0.30

t= number of years

A=V(t) = future value

so the required function is V(t)=3000(1-0.30)^t

or V(t)=3000(0.70)^t

Now plug t=4 years to get the value of computer after 4 years.

V(4)=3000(0.70)^4

V(4)=720.3

Hence final answer is $720.3.

x^2 - 6x + 8 = 0

(x - 2)(x - 4) = 0

x - 2 = 0; x = 2

x - 4 = 0; x = 4

Which function is equivalent to f(x) = lnx?
11Alexandr11 [23.1K]

Answer:

f(x)=log_ex

Step-by-step explanation:

By definition, we can write ln instead of log. WHEN??

Whenever the base of the logarithm is the number "e".

Hence, when we have:

Log_e

We can write it in shortcut as:

Log_e=ln

Hence, ln x can also be written as Log_ex

Fourth answer choice is right.
