Step-by-step explanation:
To multiply mixed numbers, convert them into improper fractions. Multiply the two improper fractions together and simplify the result.
Explanation:To multiply mixed numbers, we first convert them into improper fractions. To convert 1 1/3 into an improper fraction, we multiply the whole number (1) by the denominator (3) and add the numerator (1). This gives us 4/3. Similarly, to convert 1 4/9 into an improper fraction, we multiply the whole number (1) by the denominator (9) and add the numerator (4). This gives us 13/9.
Now, we can multiply the two improper fractions together. 1 1/3 times 1 4/9 equals (4/3) * (13/9). To multiply fractions, we multiply the numerators together and multiply the denominators together. So, (4/3) * (13/9) equals (4 * 13) / (3 * 9), which simplifies to 52/27.
Therefore, 1 1/3 times 1 4/9 in fraction form is equal to 52/27.

A company provides bus trips to various events for a adults and c children. The company charges $18 for each adult and $8 for each child for a trip to an upcoming play. The bus has a maximum capacity of 40 people and the school can only spend $400 dollars on the trip. Write and solve a system of equations to determine the maximum number of adults and children that can attend the play that will satisfy these constraints.
Final answer:
To determine the maximum number of adults and children that can attend the play without exceeding the bus capacity of 40 people and the $400 budget, set up and solve a system of equations representing the capacity and budget constraints. The solution is 8 adults and 32 children.
Explanation:
We are given a situation where a company charges $18 for each adult (a) and $8 for each child (c) for a bus trip to an upcoming play, with the constraints that the bus holds a maximum of 40 people and the available budget is $400. To find the maximum number of adults and children that can attend under these constraints, we need to set up a system of equations:
For the capacity constraint: a + c = 40
For the budget constraint: 18a + 8c = 400
We can solve this system using substitution or elimination. Let's use elimination. Multiply the first equation by -8 and add it to the second equation to eliminate c:
-8a - 8c = -320
18a + 8c = 400
Adding these two equations together gives us:
10a = 80
Thus, a = 8. Plugging a = 8 back into the first equation, we get c = 32.
The maximum number of adults and children that can attend the play is 8 adults and 32 children.

Answer:
The annual interest rate is 5.247%.
Step-by-step explanation:
Question
Claire deposited $2,500 into an account that accrues interest monthly. She made no additional deposits or withdrawals. After 2 years, Claire had $2,762.35 in the account. what is the annual interest rate of the account?
Subtract $2,500.00 from $2,762.35 and you get 262.35- the 2-year interest. To get the annual interest, divide 262.35 by 2, which equals 131.75. Then, divide 131.75 by 2,500 (original amount) and you get 0.05247. Lastly, multiply 0.05247 by 100 to get the answer (5.247%).
To find the annual interest rate, use the compound interest formula and set it equal to the final amount in the account. After performing the necessary computations, 'r' comes out to approximately 5%.
Explanation:To find the annual interest rate of Claire's account, you'll need to use the compound interest formula: v(t) = p * (1 + r/n)^(nt), where:
'p' is the initial (principal) investment, in this case $2,500;'r' is the annual interest rate, which is what we're solving for;'n' is the number of times the interest is compounded per year, which, since it's compounded monthly, is 12; and't' is the number of years since the initial deposit, which is 2 in this case.Claire's account had $2,762.35 in it after 2 years. Therefore, you would set $2,762.35 equal to the formula and solve for 'r'.
Doing so yields $2,762.35 = $2,500 * (1 + r/12)^(12*2) which simplifies, after some mathematical computations, to an annual interest rate (r) of roughly 5%.

Marcy has $20 she wants to buy a book that is marked down 30% from its original price of $28. If the sales tax is 2.5 does she have enough money
Answer:
no
Step-by-step explanation:
thirty percent of $28 is $8.4, so you would subtract the two leaving you with $19.6
2.5 sales tax of $19.6 is $0.49
Adding those two, the total comes to 20.09 which is just over budget
The amount of the book is more than $20. Then she does not have enough money.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Let 'x' be the markdown price. Then the equation is given as,
30% = [(28 - x) / 28] × 100
0.30 = [(28 - x) / 28]
8.4 = 28 - x
x = $19.6
Then the amount of book after tax is given as,
⇒ $19.6 x 1.025
⇒ $20.09
The amount of the book is more than $20. Then she does not have enough money.

Collin has $500 in his bank account. He starts saving $30.00 per week. Kamryn
has $750 in her bank account, and she is saving $20.00 per week. Assume
neither Collin nor Kamryn make any withdrawals.
After how many weeks will. Collin and Kamryn have the same amount of
money in their accounts?
Answer:
x = 25
Step-by-step explanation:
You would need to start by creating an equation. X would represent the numbers of weeks.
500 + 30x = 750 + 20x
Now get the numbers on one side. To do this subtract 500 form each side.
30x = 250 + 20x
Next, get the variables to one side. This can be done by subtracting 20x from each side.
10x = 250
Finally divide by 10 to get the variable by its self.
x = 25
Hope this helps.
After 25 weeks, Collin and Kamryn have the same amount of
money in their accounts.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the after x weeks, Collin and Kamryn have the same amount of money in their accounts:
Then we can frame a linear equation as per the problem:
Collin's amount of money = 500 + 30x
Kamryn amount of money = 750 + 20x
500 + 30x = 750 + 20x
10x = 250
x = 25
Thus, after 25 weeks Collin and Kamryn have the same amount of

On a recent survey, 60% of those surveyed indicated that they preferred walking to running.
a. If 540 people preferred walking, how many people were surveyed?
b. How many people preferred running?
Answer:
a. Number of people surveyed were 900.
b. 360 people preferred running.
Step-by-step explanation:
Given:
On a recent survey, 60% of those surveyed indicated that they preferred walking to running.
If 540 people preferred walking.
Now, to find a. number of people were surveyed. b. number of people preferred running.
a.
Number of people preferred walking = 540.
Percentage of people preferred walking = 60%.
Let the total number of people surveyed be [tex]x.[/tex]
Now, to get the number of people surveyed:
60% of x = 540.
[tex]\frac{60}{100} \times x=540[/tex]
[tex]0.60\times x=540[/tex]
[tex]0.60x=540[/tex]
Dividing both sides by 0.60 we get:
[tex]x=900.[/tex]
Thus, number of people surveyed = 900.
b.
Total number of people surveyed = 900.
People preferred walking = 540.
Now, to get the people preferred running we subtract people preferred walking from total number of people surveyed:
[tex]900-540[/tex]
[tex]=360.[/tex]
Thus, people preferred running = 360.
Therefore, a. Number of people surveyed were 900.
b. 360 people preferred running.

It's usual that students make mistakes when misunderstanding the application of algebra's basic rules. Here we have two of them
When we change the signs of all the terms of a polynomial, the expression must be preceded by a negative sign When multiplying negative and positive quantities, if the number of negatives is odd, the result is negative. If the number of negatives is even, the result is positive. Not to confuse product of fractions with the sum of fractions. Rules are quite different
The first expression is
[tex]1-x / (5-x)(-x)=x-1 / x(x-5)[/tex]
Let's arrange into format:
[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =\frac{x-1 }{ x(x-5)}[/tex]
We can clearly see in all of the factors in the expression the signs were changed correctly, but the result should have been preceeded with a negative sign, because it makes 3 (odd number) negatives, resulting in a negative expression. The correct form is
[tex]\displaystyle \frac{1-x}{(5-x)(-x)} =-\frac{x-1 }{ x(x-5)}[/tex]
Now for the second expression
[tex]5/s+2/5=2/s[/tex]
Let's arrange into format
[tex]\displaystyle \frac{5}{s}+\frac{2}{5} =\frac{2}{s}[/tex]
It's a clear mistake because it was asssumed a product of fractions instead of a SUM of fractions. If the result was correct, then the expression should have been
[tex]\displaystyle \frac{5}{s}\times \frac{2}{5} =\frac{2}{s}[/tex]

what does x equal in the function: f(-11)=5x+1
Final answer:
In the equation f(-11)=5x+1, solving for x yields x = -2.4.
Explanation:
To find what x equals in the function f(-11)=5x+1, we start by understanding that the function f(x) identifies the relation between x and f(x). In this case, f(-11) has been given the value of 5x+1. Therefore, we solve for x by setting the expression equal to f(-11).
We have the equation 5x + 1 = f(-11). Since f(-11) is given as a constant, we substitute and solve for x:
5x = -12
x = -2.4
Hence, x equals -2.4 in the function f(-11)=5x+1.
Marcos had 15 coins in nickels and quarters. He had 3 more quarters than nickels. He wrote a system of equations to represent this situation, letting x represent the number of nickels and y represent the number of quarters. What is the solution?
Answer:
Marcos had 6 nickel coins and 9 quarter coins.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of nickel coins and y be the number of quarter coins.
Marcos had 15 coins in nickels and quarters.
Thus, we can write the equation:
[tex]x + y =15[/tex]
He had 3 more quarters than nickels. We can write he equation,
[tex]y = x + 3[/tex]
Solving the two equations, we get,
[tex]2y = 18\\y = 9\\x + 9 = 15\\x = 6[/tex]
Thus, Marcos had 6 nickel coins and 9 quarter coins.
The solution to the system of equations representing Marcos's coins is x = 6 and y = 9. Hence, Marcos had 6 nickels and 9 quarters.
Explanation:This question pertains to creating and solving a system of equations in mathematics. Given Marcos had 15 coins in nickels and quarters and considering the information that he had 3 more quarters than nickels, two equations can be formed from this. The first equation sets up the total number of coins: x + y = 15. The second equation sets ups the difference in quantity of each coin: y = x + 3.
To find the solution, substitute the second equation in for y in the first equation. This gives: x + (x + 3) = 15. Solve the equation and find x = 6. Furthermore, using x in our second equation, we get y = 6 + 3 = 9. Therefore, Marcos had 6 nickels and 9 quarters.
