$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Ling bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6

Answer:
[tex]y = 2000(1.05)^{36[/tex]
Step-by-step explanation:
Given
[tex]a = 2000[/tex] -- Initial population
[tex]r = 5\%[/tex] --- Rate (monthly)
Required
Determine the population in 3 years
The question shows an exponential distribution and the final population will be calculated using:
[tex]y = a(1 + r)^x[/tex]
Where x is the number of months.
[tex]x = 3\ years[/tex]
[tex]x = 3* 12\ months[/tex]
[tex]x = 36[/tex]
So, we have:
[tex]y = 2000(1 + 5\%)^{36[/tex]
Convert % to decimal
[tex]y = 2000(1 + 0.05)^{36[/tex]
[tex]y = 2000(1.05)^{36[/tex]

what is the number 10^2×10^5 in ordinary language
I'm guessing ordinary language means not in scientific method and in words. So...
First we combine the exponent because they are multiplied with the same base getting...
10^2+5=10^7
Now we can convert this into everyday numbers...
10,000,000
Or...
10 million

Henry divided his socks into five equal groups. Let s represent the total number of socks. Which expression and solution represent the number of socks in each group if s = 20?
A) StartFraction s Over 5 EndFraction; when s = 20, the number of socks in each group is 4.
B) StartFraction s Over 5 EndFraction; when s = 20, the number of socks in each group is 15.
C) s minus 5; when s = 20, the number of socks in each group is 4.
D) s minus 5; when s = 20, the number of socks in each group is 15.
Answer:
so for each group just multiply the number of socks in each group to 5 and = s
so

The population of a school will increase by 3% per year. In 2005, the population was 127 students. Use a graph to find when the population will be
Enter the correct year in the box.
Using an exponential function, it is found that the population will be of 350 students in the year of 2039, 34.3 years after 2005.
What is an exponential function?An increasing exponential function is modeled according to the rule presented as follows:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which the parameters of the equation is defined as follows:
A(0) is the initial amount of the function.r is the growth rate of the function, as a decimal.In the context of this problem, the values of the parameters are given as follows:
A(0) = 127, which is the number of students in the reference year of 2005.r = 0.03, which is the yearly increase rate.Hence the equation for the number of students in t years after 2005 is given as follows:
[tex]A(t) = 127(1.03)^t[/tex]
The number will be of 350 students when A(t) = 350, hence:
[tex]A(t) = 127(1.03)^t[/tex]
[tex]350 = 127(1.03)^t[/tex]
[tex](1.03)^t = \frac{350}{127}[/tex]
[tex]\log{(1.03)^t} = \log{\left(\frac{350}{127}\right)}[/tex]
[tex]t\log{1.03} = \log{\left(\frac{350}{127}\right)}[/tex]
[tex]t = \frac{\log{\left(\frac{350}{127}\right)}}{\log{1.03}}[/tex]
t = 34.3 years.
34.3 years = during the year of 2005 + 34.3 = 2039. This result is shown by the graph at the end of the answer.
Missing InformationThe problem asks for when the population will be of 350 students.

What are absolute value functions?
An absolute value function is a function that contains an algebraic expression within absolute value symbols.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
According to the given question.
We have an inequality |3x| > x + 20
Solve the above given inequality |3x| > x + 20
⇒ [tex]-(x + 20) < 3x < +( x + 20)[/tex]
⇒ [tex]-x -20 < 3x < x + 20[/tex]
⇒ [tex]3x > -x -20[/tex] or [tex]3x < x + 20[/tex]
⇒ [tex]3x+x > -20[/tex] or [tex]3x - x < 20[/tex]
⇒ [tex]4x > -20[/tex] or [tex]2x < 20[/tex]
⇒[tex]x > -5[/tex] or [tex]x < 10[/tex]

10x= -11
divide by 10
x= -1.1

3.Reina has 40 pieces of bananas, 48 pieces of atis and 36 pieces of chicos. She
wants to put them equally in the plastic bag. How many possible number of
each fruit will be placed in the plastic bag?
Answer:
36
Step-by-step explanation:
If I understood your question right, it means that Reina wants to put equal amounts of fruits into the bag. Also it suggests that the volume of the bag is not limited.
Since 36 < 40 < 48, the largest amount of each kind of fruits in the bag can be 36. Otherwise Reina wouldn't be able to put more chinos and the amount of each fruit in the bag wouldn't be equal.
Assuming that the smallest amount of fruits in the bag is one (the bag is not empty), there are 36 possible numbers (from 1 to 36) of each fruit.
