exercise 2-20 (static) record transactions, post to t-accounts, and prepare a trial balance (lo2-4, 2-5, 2-6)
Answers
For the given transactions, the general journal, T accounts, and trial balance is attached.
In the given case, it is required to record all transactions using the general journal, post them into corresponding T accounts. After posting all transactions, ending balances are calculated. The ending balances are used to create a Trial Balance.
The general journal is a book of original entries where the raw business transactions is recorded according to the date events occur. It is the first place where data is recorded . The general journal for the provided data is attached (figure 1).
Each transaction from the journal to corresponding T-accounts and their ending balances are calculated by subtracting credits from debits for accounts with debit balance and subtracting debits from credits for account with credit balance. A T-account is an informal term which is used for a set of financial records that use double-entry bookkeeping. It is a graphical representation of a general ledger where business’ transactions are recorded. It consists of the an account title at the top, a debit side on the left, and a credit side on the right. It is called a T-account because the bookkeeping entries are laid out in a way that resembles a T-shape. The T-account for the given data is attached (figure 2 and 3).
Trial balance is prepared by entering corresponding ending balances from T accounts and calculating the sums of debit and credit. A trial balance refers to a bookkeeping worksheet where the balances of all ledgers are compiled into debit and credit account column totals that are equal. The general purpose is to ensure that the entries in a company’s bookkeeping system are mathematically correct. The trial balance for the given data is attached (figure 4).

A culture of bacteria has an initial population of 9300 bacteria and doubles every 3
hours. Using the formula P = Po 25, where Pt is the population after thours, P
is the initial population, t is the time i hours and d is the doubling time, what is the
population of bacteria in the culture after 10 hours, to the nearest whole number
Answers
Answer:
The approximate population of bacteria in the culture after 10 hours is 93,738.
Step-by-step explanation:
General Concepts:Exponential Functions.Exponential Growth.Doubling Time Model.Logarithmic Form.BPEMDAS Order of Operations:
Brackets.Parenthesis.Exponents.Multiplication.Division.Addition.Subtraction.Definitions:We are given the following Exponential Growth Function (Doubling Time Model), \(\displaystyle\mathsf{P_{(t)}\:=\:P_0\cdot2^{(t/d)}}\) where:
\(\displaystyle\sf{P_t\:\:\rightarrow}\) The population of bacteria after “t ” number of hours. \(\displaystyle\sf{P_0 \:\:\rightarrow}\) The initial population of bacteria. \(\displaystyle{t \:\:\rightarrow}\) Time unit (in hours). \(\displaystyle{\textit d \:\:\rightarrow}\) Doubling time, which represents the amount of time it takes for the population of bacteria to grow exponentially to become twice its initial quantity. Solution:Step 1: Identify the given values.
\(\displaystyle\sf{P_0\:=}\) 9,300. t = 10 hours. d = 3.Step 2: Find value.
1. Substitute the values into the given exponential function.
\(\displaystyle\mathsf{P_{(t)} = P_0\cdot2^{(t/d)}}\)
\(\displaystyle\mathsf{\longrightarrow P_{(10)} = 9300\cdot2^{(10/3)}}\)
2. Evaluate using the BPEMDAS order of operations.
\(\displaystyle\mathsf{P_{(10)} = 9300\cdot2^{(10/3)}\quad \Longrightarrow BPEMDAS:\:(Parenthesis\:\:and\:\:Division).}\)
\(\displaystyle\sf P_{(10)} = 9300\cdot2^{(3.333333)}\quad\Longrightarrow BPEMDAS:\:(Exponent).}\)
\(\displaystyle\sf P_{(10)} = 9300\cdot(10.079368399)\quad \Longrightarrow BPEMDAS:(Multiplication).}\)
\(\boxed{\displaystyle\mathsf{P_{(10)} \approx 93,738.13\:\:\:or\:\:93,738}}\)
Hence, the population of bacteria in the culture after 10 hours is approximately 93,738.
Double-check:We can solve for the amount of time (t ) it takes for the population of bacteria to increase to 93,738.
1. Identify given:
\(\displaystyle\mathsf{P_{(t)} = 93,738 }\).\(\displaystyle\mathsf{P_0 = 9,300}\).d = 3.2. Substitute the values into the given exponential function.
\(\displaystyle\mathsf{P_{(t)} = P_0\cdot2^{(t/d)}}\)
\(\displaystyle\mathsf{\longrightarrow 93,378 = 9,300\cdot2^{(t/3)}}\)
3. Divide both sides by 9,300:
\(\displaystyle\mathsf{\longrightarrow \frac{93,378}{9,300} = \frac{9,300\cdot2^{(t/3)}}{9,300}}\)
\(\displaystyle\mathsf{\longrightarrow 10.07936840 = 2^{(t/3)}}\)
4. Transform the right-hand side of the equation into logarithmic form.
\(\boxed{\displaystyle\mathsf{\underbrace{ x = a^y}_{Exponential\:Form} \longrightarrow \underbrace{y = log_a x}_{Logarithmic\:Form}}}\)
\(\displaystyle\mathsf{\longrightarrow 10.07936840 = \bigg[\:\frac{t}{3}\:\bigg]log(2)}\)
5. Take the log of both sides of the equation (without rounding off any digits).
\(\displaystyle\mathsf{log(10.07936840) = \bigg[\:\frac{t}{3}\:\bigg]log(2)}\)
\(\displaystyle\mathsf{\longrightarrow 1.003433319 = \bigg[\:\frac{t}{3}\:\bigg]\cdot(0.301029996)}\)
6. Divide both sides by (0.301029996).
\(\displaystyle\mathsf{\frac{1.003433319}{0.301029996} = \frac{\bigg[\:\frac{t}{3}\:\bigg]\cdot(0.301029996) }{0.301029996}}\)
\(\displaystyle\mathsf{\longrightarrow 3.3333333 = \frac{t}{3}}\)
7. Multiply both sides of the equation by 3 to isolate "t."
\(\displaystyle\mathsf{(3)\cdot(3.3333333) = \bigg[\:\frac{t}{3}\:\bigg]\cdot(3)}\)
\(\boxed{\displaystyle\mathsf{t\approx10}}\)
Hence, it will take about 10 hours for the population of bacteria to increase to 93,378.

A fraction of the students who have brown hair is equal to 1/7.
You should shade only one (1) section on the pie chart to show the number of students with brown hair.
What is a pie chart?In Mathematics, a pie chart can be defined as a type of graph that is used for the graphical representation of the proportion relationship between each part or unit to a whole, especially by dividing a circle into various sectors or sections.
Based on the information provided in the table (see attachment), we can logically deduce the following parameters about the various hair color;
Number of brown hair = 1 brown hair.
Number of blonde hair = 4 blonde hair.
Number of black hair = 2 black hair.
Therefore, the total number of hairs is equal to 7 hairs.
For the fraction of students with brown hair, we have;

Jackie is analyzing a quadratic function f(x) and a linear function g(x). Will they intersect?f(x)g(x)graph of the function f of x equals one half times x squared, plus 1xg(x)1−12−23−3
Answers
There is no intersection between f(x) and g(x)
1) Considering that f(x) is described as:
\(f(x)=\frac{1}{2}\mleft(x\mright)^2+1\)2) So if we want to check whether both functions intersect each other. Let's examine the table for g(x) function.
If they intersect they must share the same results so let's equate them. But first, let's find g(x)
\(\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1}=\frac{-2-(-1)}{2-1}=\frac{-2+1}{1}=-1 \\ (1,-1) \\ y=mx+b \\ -1=-1(1)+b \\ -1+1=b \\ g(x)=-x \end{gathered}\)3) Plotting both graphs, we can tell whether there is or there is not an intersection between both functions.
So they do not intersect.

Three men walk into a hotel and ask to share a room. The cost is going to be $270 for
the night. Each man puts in a $100 bill and they get 3 $10 bills in change. The bell boy
carries their luggage and they each decide to be generous and tip the bell boy their change.
The front desk realizes they miss-charged the men, so the bell boy takes a $20 bill change to
the room. The men realize that you can’t split the $20 bill evenly 3 ways so they add it onto
the tip. The bell boy is happy but then thinks to himself: ”If the room is $270 and they had
this extra $20 that’s only $290, where did the other $10 go?”
Explain what is wrong with the Bell Boy’s thoughts, and what is the correct math here.
Answers
Answer:
Step-by-step explanation:
The bell boy added $270 and $20 incorrectly. The $20 bill was something that was returned due to overcharching. On the other hand, $270 was the amount that they paid for their room. This only means that $20 should be deducted from $270 and that's the amount that they paid for their room while $30 and $20 are the amount that the bell boy received as a tip
Total money of the three men: 3($100) = $300
They paid $270 for the room: $300 - $270 = $30
Tip for the bell boy: $30 - $30 = $0
Amount overcharged to them: $0 + $20 = $20
Tip to the bell boy: $20 - $20 = $0
They were left with no more money from the original $300.
