2) The debate team with 18 members is to choose four officers: captain, co-captain, treasurer, and secretary. How many ways can those officers be selected?
Answers
We have 18 members that can be positioned in 4 positions.
As the positions are different from each other, the order matters.
Then, this is a permutation of 18 elements in 4 places with no repetition.
The number of permutations can be calculated as:
[tex]\begin{gathered} P(n,r)=\frac{n!}{(n-r)!} \\ P(18,4)=\frac{18!}{(18-4)!}=\frac{18!}{14!}=18\cdot17\cdot16\cdot15=73440 \end{gathered}[/tex]We could have derived this by doing this analysis:
We have 18 to choose for captain.
Then, we have 17 left to choose for co-captain.
Finally 16 can be chosen for treasurer and 15 are left for secretary.
Then, the posible teams are 18*17*16*15=73440.
Answer: we can select them in 73,440 ways.
Dawn's suitcase weighed 25 kilograms. Convert this weight to pounds. (Round youranswer to the nearest tenth.)
Answers
Given: Dawn's suitcase weighed 25 kilograms.

Katy has $40 in a savings account. The interest rate is 5%, compounded annually.To the nearest cent, how much interest will she earn in 3 years?What’s the answer
Answers
Given:
Katy has $40 in a savings account.
So, the principal = P = 40
The interest rate = r = 5% = 0.05
compounded annually, n = 1
Time = t = 3 years
So, Amount of money after 3 years = A
[tex]\begin{gathered} A=P\cdot(1+\frac{r}{n})^{nt} \\ A=40\cdot(1+\frac{0.05}{1})^3=46.305 \end{gathered}[/tex]So, the interest = A - P =
[tex]46.305-40=6.305[/tex]Rounding to the nearest cent
So, the answer will be:

Write an equation of a circle giving its Center and radius or diameter.
Answers
The equation of a circle with center (h,k) and radius r is given as:
[tex](x-h)^2+(y-k)^2=r^2[/tex]From the question, it is given that the center of the circle is (-7,-4) and the diameter is 8.
Since the radius is half the diameter, it follows that the radius is:
[tex]\frac{\text{diameter}}{2}=\frac{8}{2}=4[/tex]So it implies that r=4, h=-7, and k=-4.
Substitute these values into the equation of a circle:
[tex]\begin{gathered} (x-(-7))^2+(y-(-4))^2=4^2 \\ \Rightarrow(x+7)^2+(y+4)^2=16 \end{gathered}[/tex]Hence, the equation of the circle is:
[tex](x+7)^2+(y+4)^2=16[/tex]
Convert 0.111... to a repeating fraction. simplify if you can
Answers
Explanation:
To convert from a repeating decimal number to a fraction we have to do the following steps:
1. Let 'x' be the repeating decimal:
[tex]x=0.111\ldots[/tex]2. Let 'n' be the number of decimals that repeat. In this case n = 1
3. Multiply both sides of point 1 by 10^n:
[tex]10x=1.111\ldots[/tex]4. Substract (1) from (3) to eliminate the repeating part:
[tex]\begin{gathered} 10x-x=1.111\ldots-0.111\ldots \\ 9x=1 \end{gathered}[/tex]5. Solve for x:

Sam is making Apple Pies and Pumpkin Pies for her Pie shop. She sells eachApple Pie for $6 and each Pumpkin Pie for $7. If Sam sells a total of 80 piesone day and makes a total of $512, how many apple pies did she sell?
Answers
Let m represent the number of apple pies Sam is making and
Let n represent the number of pumpkin pies Sam is making
If Sam sells a total of 80 pies, this can be represented by
m + n = 80 ------------------------------equation (1)
If she makes a total of $512 on the same day, this cost can be represented by
6m + 7n = 512 ----------------------------equation (2)
Solving both equations simultaneously
m + n = 80
6m + 7n = 512
from m + n = 80,
m = 80 - n
substitute m = 80 - n into equation (2)
we have
6(80 -n) + 7n = 512
480 - 6n + 7n = 512
480 + n = 512
n = 512 - 480
n = 32
Put n = 32 into m = 80 - n
we have
m = 80 - 32
m = 48
The number of apple pies Sam sell is 48

What is problem-solving?
Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.
Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.
Calculation:-
Richard and Teo have a combined age = of 32
Richard is 7 years older than twice Teo's age
Let the age of Teo = X
Age of Richard = 2X + 7
2X + 5+ X = 31
X = 31 - 5 /3
X = 27/3
= 9 years
Therefore the age of Teo is 8 years
Age of Richard = 19 years

Answers
System of equations
A system of equations with two variables can have one solution, no solution, or infinitely many solutions.
Each equation corresponds to a line which can be expressed like:
y = mx + b
Where m is the slope and b is the y-intercept
For a system to have one solution, both lines must have different slopes, so they cross each other at one point.
If a system has no solution, both lines are parallel
If a system has infinitely many solutions, both lines are the same line (they coincide)
We have the following equation:
5x + 2y = -4
Let's solve it for y:
2y = - 5x -4
[tex]y=-\frac{5}{2}x-2[/tex]Only one of the lines has the same slope as the given line:
[tex]y=-\frac{5}{2}x-3[/tex]Both lines have the same slope but don't have the same y-intercept, so they are parallel.
Thus, the correct choice is D.
