Mildred brought 1 cent stamps,32 cent stamps, and 33 cent stamps for $21.80. The number of 1 cent stamps exceed the number of 33 cent stamps by 50. The number of 32 cents was 10 less than twice the number of 33 cents stamps. How many of each kind did she buy? Mildred brought 1 cent stamps,32 cent stamps, and 33 cent stamps for $21.80. The number of 1 cent stamps exceed the number of 33 cent stamps by 50. The number of 32 cents was 10 less than twice the number of 33 cents stamps. How many of each kind did she buy?
Mildred bought 480 1 cent stamps, 410 32 cent stamps, and 520 33 cent stamps.
Explanation:Let's solve this problem using a system of equations.
Let's use the variables x, y, and z to represent the number of 1 cent stamps, 32 cent stamps, and 33 cent stamps respectively that Mildred bought. We can write the following equations based on the information given:
x + y + z = 2180 (since the total cost was $21.80)
x = z + 50 (since the number of 1 cent stamps exceed the number of 33 cent stamps by 50)
y = 2z - 10 (since the number of 32 cent stamps was 10 less than twice the number of 33 cents stamps)
Let's solve this system of equations:
Substitute the value of x from equation 2 into equation 1: (z + 50) + y + z = 2180Substitute the value of y from equation 3 into equation 1: z + 50 + (2z - 10) + z = 2180Simplify and solve for zSubstitute the value of z into equation 2 to find xSubstitute the value of z into equation 3 to find yAfter solving the system of equations, we find that Mildred bought 480 1 cent stamps, 410 32 cent stamps, and 520 33 cent stamps.

The question seeks the derivatives of a function, but cannot be answered accurately due to the lack of specific information about the function provided.
The question asks to find the first, second, and third derivatives of a given function f(x). However, further details needed to answer the question, such as the specific form of the function f(x), are not provided in the question itself. Therefore, without the explicit function f(x), we cannot proceed to accurately calculate the requested derivatives.
In how many different ways can you answer a multiple choice test that has 5 questions and 3 choices for each answer? 15 125 243
Answer:
The correct option is 3. The total number of different ways to answer a multiple choice test is 243.
Step-by-step explanation:
Total number of questions is 5. Each question has three options.
Total number of ways to answer the first question is 3.
Similarly, the number of ways to answer each question is 3.
Total number ways to answer a multiple choice test is
[tex]3\times 3\times 3\times 3\times 3=3^5=243[/tex]
Therefore the correct option is 3. The total number of different ways to answer a multiple choice test is 243.
A restaurant charges $100 to rent its banquet room for an event. It also charges $15 to serve dinner to each quest. Write an equation for the total cost of the banquet room in terms of the number of guests. Define your variables. What is the total cost of the banquet room for 20 guests?
Answer:
The total cost function is C (x) = 15x + 100 and the cost of a banquet for 20 guests is $ 400
Step-by-step explanation:
Let's suppose,
X: Number of guests
C (x) = total cost
CF (x) = fixed cost
CV (x) = variable cost
C (x) = CV (x) + CF (x)
For the situation presented,
CF (x) = 100
CV (x) = 15x
With this information, the function that provides the total cost is given by the expression:
C (x) = 15x + 100.
When there are 20 guests, the total cost of the banquet is:
C (20) = 15 (20) + 100 = 300 + 100 = 400
Conclusion: The total cost function is C (x) = 15x + 100 and the cost of a banquet for 20 guests is $ 400

Hunter bought a package of 24 pencils for $3.12. Write and solve an equation to determine the cost of each pencil in the package
The cost of each pencil in the package is $0.13.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that a Hunter bought a package of 24 pencils for $3.12.
We have to find the cost of each pencil.
Let x be the cost of each pencil.
A pack of 24 pencils is three point one two
24x=3.12
Divide both sides by 24
x=3.12/24
Three point one two divided by twenty four.
x=0.13
Hence, the cost of each pencil in the package is $0.13.

Today is Jack’s birthday and Jill’s birthday. Jack is five and Jill is nine.
1. How many years ago was Jill twice as old as Jack?
2. When Jack is three quarters as old as Jill, how old will Jill be?
3. When Jill was three times as old as Jack, how old was Jack?
4. When Jill is four times as old as Jack is today, how old will Jack be?
Final answer:
The problem involves simple arithmetic and algebra to work out the relationship between ages at different times. Jill was twice as old as Jack 1 year ago. The other parts of the problems are under-determined or have errors that prevent firm conclusions.
Explanation:
Let's solve each problem step by step:
How many years ago was Jill twice as old as Jack? Let's call the number of years ago y. Jill's age y years ago = 9 - y, and Jack's age y years ago = 5 - y. The equation based on the problem is 9 - y = 2(5 - y). Solving this equation, y = 1. So, Jill was twice as old as Jack 1 year ago.
When Jack is three quarters as old as Jill, how old will Jill be? Let's call Jill's future age f. Jack's future age will be 3/4 * f. We know Jack is currently 5 years old, so 5 + x = 3/4(f + x), where x is the number of years till that happens. To find the value of f and x, we need one more equation or piece of information, which is not provided.
When Jill was three times as old as Jack, how old was Jack? To find this out, we set up an equation similar to the first problem: let's call the number of years ago z. So (9 - z) = 3(5 - z), solving for z gives us z = 4.5, but since they can't be half years old, we must consider whole years; thus, this situation hasn't occurred given their current ages or an error exists in the problem.
When Jill is four times as old as Jack is today, how old will Jack be? Jack is currently 5. So, when Jill is four times that age, she will be 5 * 4 = 20 years old. We cannot determine how old Jack will be at that time without knowing the difference in time between now and then.
