Carter and his children went into a movie theater and he bought $33 worth of drinks and candies. Each drink costs $4.50 and each candy costs $3. He bought 3 times as many drinks as candies. Determine the number of drinks and the number of candies that Carter bought.
The number of drinks and the number of candies that Carter bought are 6 and 2 respectively.
How to determine the number of drinks and candies?In order to determine the number of drinks and the number of candies that Carter bought, we would have to write a system of linear equation and assign variables to the number of drinks and number of candies respectively, and then translate the word problem into algebraic equation as follows:
Let the x indicate the number of drinks.Let the y indicate the number of candies.Since each drink costs $4.50 and each candy costs $3 and Carter bought 3 times as many drinks as candies;
x = 3y .......equation 1.
4.50x + 3y = 33 .......equation 2.
Substituting equation 1 into equation 2, we have:
4.50(3y) + 3y = 33
13.50y + 3y = 33
16.50y = 33
y = 33/16.50
y = 2 candies.
For the value of x, we have:
x = 3(2)
x = 6 drinks.

The population of a town has been decreasing since 1991. The population of the town was 26,700 people in the year 1995. In the year 2003, the population of the town had decreased to 20,300 people.

v. In what year will the population of the town be 14,700?
Year:
Answer:
i. P = -800t + 29900
ii. as an inequality: 0≤t≤37.375; interval notation: [0,37.375]
iii. as an inequality: 0≥P≥29900; interval notation: [0,29900]
iv. the population decreases at a rate of 1600 people every 3 years
v. 2010
Step-by-step explanation:
i. a) use the points *(4,26700) and **(12,20300) to find the slope (m)
*: the year 1995(4 years after 1991) and the population that year
**: the year 2003(12 years after 1991) and the population that year
m = (20300-26700)/(12-4) = -6400/8 = -800
b) use one of the points and m in (a) to find b
26700 = -800(4) + b
26700 = -3200 + b
29900 = b
ii. starting value for domain will be 0 since 1991 is year 0. Find the ending domain value by using P=0 and solving the equation for t:
0 = -800t + 29900
800t = 29900
t = 37.375
iii. population starts at a high of 29900 people and can't go lower than 0 people.
iv. the slope is given in (population change) / (number of years)
v. make P=14700 and solve the equation for t
14700 = -800t + 29900
800t = 15200
t = 19 (19 years after 1991)

b. Solve this system using either Elimination or Substitution, show your work, and state your answer as a complete sentence.
The number of cows is 12 and number of chickens are 36.
What is a system of linear equation?A "system" of equations is a set or collection of equations that you deal with all together at once.
Given that, Farmer John has cows and chickens on his farm. His farm animals have 120 legs and 48 heads total.
Let the number of chickens be x and that of cows be y,
A cow has 4 legs and that of chickens have 2,
Setting the equations, we get,
2x+4y = 120
x+2y = 60
x+y = 48
Solving the equation by elimination, we get,
2y - y = 60 - 48
y = 12
Therefore, x = 36
Hence, The number of cows is 12 and number of chickens are 36.

Answer:
Step-by-step explanation:
:On hand she has a 20% acid solution and a 50% acid solution. How many ml of each solution should sheStep-by-step explanation:this is the answer
A chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.
What is percentage?The percentage is the ratio of number expressed as a fraction of 100.
Assume chemist needs x mL of 20% of acidic solution and y mL of 50% acidic solution.
A total of 100mL solution is to be created.
x+y=100
x=100-y
The concentration of 20% acidic solution will be 0.2x, concentration of 50% acidic solution will be 0.5x and the sum of their concentrations should be 0.38(100).
0.2x+0.5y=0.38(100)
0.2x+0.5y=38
Substitute x=100-y into the obtained equation.
0.2(100-y)+0.5y=38
20-0.2y+0.5y=38
20+0.3y=38
0.3y=18
y=18/0.3
y=60
Substitute y=60 into x=100-y.
x=100-60
=40
So, the chemist needs 40mL of 20% acidic solution and 60mL of 50% acidic solution.

Consider a weighted voting system with three players. If n one has veto power, and no one is a dummy., find the Banzhof power distribution.
Player 1 ____
Player 2 ____
Player 3 ____
Give each value as a fraction or decimal.
The Banzhaf power distribution value in the fraction is,
Player 1: = 0.6
Player 2: = 0.2
Player 3: = 0.2.
What is the distribution?
The mathematical expression known as a distribution function expresses the likelihood that a system would adopt a certain value or range of values. The traditional examples include games of chance.
List of winning coalitions:
1. P1, P2, P3
2. P1, P2
3. P1, P3
No. of times P1 is critical = 3 (P1 is critical all 3 times as it has veto power)
No. of times P2 is critical = 1 (in the second coalition)
No. of times P3 is critical = 1 (in the third coalition)
Total no. of critical times = 3 + 1 + 1 = 5
Banzhof Power Distribution:
Player 1: No. of times P1 is critical/Total no. of critical times
= 3/5 = 0.6
Player 2: No. of times P2 is critical/Total no. of critical times
= 1/5 = 0.2
Player 3: No. of times P3 is critical/Total no. of critical times
= 1/5 = 0.2
Hence, the Banzhaf power distribution value in the fraction is,
Player 1: = 0.6
Player 2: = 0.2
Player 3: = 0.2
