The amount of production in the economy to meet the final consumer demand which is 80 units of agriculture, 60 units of manufacturing and 50 units of energy
How to find the amount?The given parameters that will help us to calculate the amount are
(1) Pe =0.2Pa + 0.2 Pm + 0.1pe
Pm = 0.2P + 0.4 Pm + 0.1 Pe
Pa = 0.1 Pa + 0.2Pm -0.3 Pa
(2) The free variable Pa = 100
We create a table of outputs using the given Units economy distribution
Agriculture Manufacture Energy Purchased by
0 .2 0.2 0.1 Agriculture
0.2 0.4 0.1 manufacturing
0.1 0.2 -0.3 Energy
Let Pa, Pm, Pe represent the prices for each sector
We then create an income equation using the expenses of the table above we have
(1) Pa =0.2Pa + 0.2 Pm + 0.1pe =80
Pm = 0.2P + 0.4 Pm + 0.1 Pe = 60
Pe = 0.1 Pa + 0.2Pm -0.3 Pa=50
Making pa, pm and pe the subjects of the relation and summing them to have the amount
pa = 0.5x = 80
Pa=80/0.5= 160
Pm = 0.7pm = 60
Making pm the subject of the formula
pm= 60/0.7 = 86
Pe = 0
Therefore the amount is 160+86+0 = 246

The dollar value vt of a certain car model that is t years old is given by the following exponential function.
v(t)= 25,900(0.90)^2
Find the initial value of the car and the value after 11 years.
Round your answers to the nearest dollar as necessary.
Initial Value:
Value after 11 years:
Answer:
$25,900 initially
$8,128 after 11 years
Step-by-step explanation:
One thing to note, is I'm assuming you meant: [tex]v(t)=25,900(0.90)^t[/tex] and not [tex]v(t)=25,900(0.90)^2[/tex], otherwise that would just be a constant function and not an exponential function.
Exponential Function Key Features:There are a couple key features of exponential functions we can derive from simply analyzing the equation.
For now I will be using the form: [tex]y=a(b)^x\text{ where b} > 0, \text{b}\ne 1[/tex]
y-intercept:The y-intercept, is just the "a" value, which is because the y-intercept is simply when x=0, and if we raise a number to the power of zero, we get one (excluding zero as a base), so we get the form: [tex]y=a[/tex], so "a" is our y-intercept.
Rate of Change:there's actually two type of exponential functions: exponential growth and exponential decay.
Exponential Decay:
Exponential decay, as the name implies, is when a function is decaying or decreasing. This occurs when [tex]0 < b < 1[/tex].
The decay rate can be represented as "r" in decimal form, where: [tex]b=1-r[/tex].
The reason for this is because "1" can be thought of as 100% and "r" is r%, so you're taking away r% or decaying the value by r%, also known as a decay rate.
Exponential Growth:
Exponential growth as the name implies, is when a function is growing or increasing. This occurs when b > 1
The growth rate can be represented as "r" in decimal form where: [tex]b=1+r[/tex]
The reason for this is similar to decay rate except instead of taking away r% or decaying, it's "giving r%" or growing.
Solving the Question:The question doesn't actually require finding exponential growth or decay, but it's still an important key feature.
In this case, we really just need to find the y-intercept and plug in t=11.
The y-intercept in many graphs, not just exponential graphs, represents some sort of initial value, which in this case, is the initial value of the car. As stated above, this y-intercept is just the value in front, which is 25,900.
As for the value after 11 years, we simply need to plug in t=11 to get the following: [tex]v(11)=25,900(0.90)^{11}[/tex], from here we can use a calculator to simplify this: [tex]v(11)\approx25,900(0.31381059609)\approx 8,127.694438731[/tex], which rounds to 8,128
1. Peter and John went shopping and spent money in the ratio 2 : 3 .
(a) If Peter spent 500 dollars, how much did John spend?
(b) If John spent 600 dollars, how much did they spend altogether?
(c) If both boys spent 2000 dollars altogether, how much did they spend?
(d) If John spent 100 dollars more than Peter, how much did both boys spend?
The ratio of the amount Peter spent to that of John is 2:3, so:
(a) If Peter spent 500 dollars, then John spent 75p dollars
(b) If John spent 600 dollars, then they spend altogether 1000 dollars.
(c) If both boys spent 2000 dollars altogether, then John spent 1200 dollars and Peter spent 800 dollars.
(d) If John spent 100 dollars more than Peter, then they both spent 500 dollars as Peter will spend 200 dollars while John spends 300 dollars.
How to evaluate for the amount spent using their ratio.Let us represent the amount of money spent for Peter and John with P and J respectively.
Using the ratio 2:3 for the amount Peter spent to that of John;
If Peter spent 500 dollars, then;
2/3 = $500/J {cross multiply}
J = (3 × $500)/2
J = $1500/2
J = $750
If John spent 600 dollars, then;
2/3 = P/$600 {cross multiply}
P = (2 × $600)/3
P = $1200/3
P = $ 400
Peter and John spent altogether = $1000
If both boys spent 2000 dollars altogether, then;
their total ratio = 5
unit amount = $2000/5
unit amount = $400
Peter spent = 2 × $400 = $800
John spent = 3 × $400 = $1200
If John spent 100 dollars more than Peter, then;
2/3 = P/(P + $100) {cross multiply}
3P = 2(P + $100)
3P = 2P + $200 {collect like terms}
3P - 2P = $200
P = $200.
Peter spent = $200
John spent = $300.
In conclusion, using the ratio 2:3 for the amount of money spent by Peter and John respectively, we have the answers: $750, $1000, $800 for Peter and $1200 for John, and $200 for Peter and $300 for John for the questions lettered (a), (b), (c), and (d) respectively.

Part 1
A car with a full tank that holds 11.6 gallons of gasoline is using 1.45 gallons per hour. Is the tank more than half full of gasoline after 3.5 hours? Explain your answer.
Answer:
Yes, the tank is more than half full of gasoline after 3.5 hours.
Step-by-step explanation:
To calculate the amount of gasoline left in the tank after 3.5 hours, we need to subtract the amount used (1.45 gallons per hour) from the total capacity (11.6 gallons). So 11.6 - (1.45 x 3.5) = 9.3 gallons, which is more than half the tank's capacity of 11.6 gallons. Hope this helps!

If 3/5 of the freshmen are in favor of the school forming a track team and 1/5 of the remaining students (not freshmen) are also in favor of forming a track team, how many students are opposed to this idea?
First, we need to find the number of students that are freshmen: 3400 students x 3/8 = 1050 students
Next, we need to find the number of students that are in favor of forming a track team: 3/5 of the freshmen are in favor = 3/5 * 1050 = 630 students
To find the number of non-freshmen students: 3400 students - 1050 students = 2350 students
Now we need to find the number of non-freshmen students in favor of forming a track team: 1/5 of the non-freshmen students are in favor = 1/5 * 2350 = 470 students
Finally, to find the number of students opposed to the idea we need to subtract the number of students in favor from the total number of students: 3400 students - (630 students + 470 students) = 3400 - 1100 = 2300 students
So there are 2300 students at Central High School that are opposed to the idea of forming a track team.

Answer:
The average rate of change is −10.
Step-by-step explanation:
The average rate of change of f(x) on the interval [a,b] is f(b) − f(a) / b−a.
We have, a=3, b=5, f(x) = -1x^2 − 2x + 2.
Thus, f(b) − f(a) = −(5)^2 −2(5) + 2 − [−(3)^2 −2(3) + 2]
= -25 - 10 + 2 - ( -9 - 6 + 2 )

Then, b−a = 5 - 3 = 2
f(b) − f(a) / b−a = - 20 / 2 = −10

Answer: D
Step-by-step explanation:
72 boxes is 5% of how many boxes?
Answer:
1440
Step-by-step explanation:
"Percent" means "out of 100"
5 "percent" means 5 out of 100
[tex]\frac{5}{100} =\frac{72}{x}[/tex]
We need to find the number that when multiplied by 5, equals 72.
72 / 5 = 14.4
Now, we need to multiply 100 by 14.4 to "scale" proportionately.
100 * 14.4 = 1440
We can check our work:
1440 * (0.05) = 72
