In Accounting if the balance in the Allowance for Doubtful accounts account is $2,000, and im adding $500 to the Allowance for doubtful Accounts account and im ONLY DOING A GENERAL JOURNAL ENTRY does the previous Allowance for doubtfull accounts come in play at all?
Answer: The journal entry to record the addition of $500 to the Allowance for Doubtful Accounts account would be:
Debit Allowance for Doubtful Accounts account: $500
Credit Bad Debt Expense account: $500
The resulting balance in the Allowance for Doubtful Accounts account would be $2,500.
Step-by-step explanation:
Yes, the previous balance in the Allowance for Doubtful Accounts account does come into play when you add $500 to the account. The Allowance for Doubtful Accounts account is a contra asset account that is used to offset the Accounts Receivable account. It represents an estimate of the amount of accounts receivable that are expected to be uncollectible.
The balance in the Allowance for Doubtful Accounts account is based on the estimated amount of uncollectible accounts, which is typically a percentage of the total accounts receivable balance. When you add $500 to the account, you are increasing the estimated amount of uncollectible accounts.
To record this journal entry, you would debit the Allowance for Doubtful Accounts account for $500 and credit an expense account (such as Bad Debt Expense) for the same amount. The previous balance of $2,000 would also be included in the account balance and would be reflected in the new balance of $2,500.
The journal entry to record the addition of $500 to the Allowance for Doubtful Accounts account would be:
Debit Allowance for Doubtful Accounts account: $500
Credit Bad Debt Expense account: $500
The resulting balance in the Allowance for Doubtful Accounts account would be $2,500.

How do I find the lengths of sides that are cut by an altitude? (right triangle, the sides that the arrows are pointing at)
The length of line JC is 20 miles.
What is Pythagorean theorem?
The Pythagorean theorem is a fundamental concept in geometry that states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of sides of triangle.
To find the length of line JC, which is the hypotenuse of the right triangle JSC, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse).
In this case, we have:
JS² + SC² = JC²
Substituting the given values, we get:
12² + 16² = JC²
144 + 256 = JC²
400 = JC²
Taking square root both sides, we get:
JC = √400
JC = 20

2. Big Money Bank has an offer for new customers: if you deposit
$5,000 in a savings account, you will earn 6.5% simple interest
over the first 10 years.
C. At the town savings bank a new customer earns $2950 in simple interest on a $5000 deposit over the first 10 years what rate of interest does that bank pay
Answer:
We can use the simple interest formula to find the rate of interest that the town savings bank pays:
Simple Interest = Principal x Rate x Time
where Principal is the initial deposit, Rate is the interest rate, and Time is the time period.
We know that the Principal is $5000, the Simple Interest earned over the first 10 years is $2950, and the Time is 10 years. Substituting these values into the formula, we get:
$2950 = $5000 x Rate x 10
Simplifying the equation, we get:
Rate = $2950 / ($5000 x 10)
Rate = 0.059 or 5.9%
Therefore, the town savings bank pays an interest rate of 5.9% on its savings accounts.

If Mrs lam worked a total of 180 hours in 9 months she worked 5 days each month then, Mrs. Lam worked 4 hours each day.
What is a bar diagram?Bar graphs or bar charts are visual depictions of groups of data that are made up of vertical or horizontal rectangular bars with lengths that are equal to the data's measure.
The variable quantity is shown on one of the axes, and the drawn bars are all of the same width. Moreover, the other axes show the variable's measure. These graphs are also used to compare different numbers since the heights or lengths of the bars represent the value of the variable. Bar charts make it simple to grasp the data and show frequency distribution tables, which facilitates computations.
Let us suppose the number of hours worked each day = x.
Given that, Mrs lam worked a total of 180 hours in 9 months she worked 5 days.
Thus,
Total hours = 180 = 5 * 9 * x
180 = 45x
x = 4

What is the inverse of f is f(x) = 3^square root of (x-4)
Answer:
the inverse of f(x) = 3^(sqrt(x-4)) is f^-1(x) = ((ln x)/ln 3)^2 + 4.
Step-by-step explanation:
To find the inverse of f(x) = 3^(sqrt(x-4)), we can follow these steps:
Step 1: Replace f(x) with y:
y = 3^(sqrt(x-4))
Step 2: Swap x and y:
x = 3^(sqrt(y-4))
Step 3: Solve for y:
Take the natural logarithm (ln) of both sides to bring down the exponent:
ln x = ln(3^(sqrt(y-4)))
Using the rule that ln(a^b) = b ln(a), we can simplify the right side:
ln x = (sqrt(y-4)) ln 3
Divide both sides by ln 3:
(sqrt(y-4)) = (1/ln 3) ln x
Square both sides:
y - 4 = ((ln x)/ln 3)^2
Add 4 to both sides:
y = ((ln x)/ln 3)^2 + 4
Step 4: Replace y with f^-1(x):
f^-1(x) = ((ln x)/ln 3)^2 + 4
Therefore, the inverse of f(x) = 3^(sqrt(x-4)) is f^-1(x) = ((ln x)/ln 3)^2 + 4.

Suppose a recent government report indicates that 6% of the labor force is Asian. Of the individuals in the labor force who are Asian, 5% are unemployed. Among the individuals in the labor force who are not Asian, 6% are unemployed. Let be the event that a randomly selected member of the labor force is Asian and let be the event that a randomly selected member of the labor force is unemployed. Determine (∣) , the probability that a randomly selected member of the labor force is Asian given that he or she is unemployed. Express your answer as a percentage with no decimal places.
Answer:
The probability that a randomly selected member of the labor force is Asian given that he or she is unemployed is 4.98%
Step-by-step explanation:
We want to find the probability that a randomly selected member of the labor force is Asian given that he or she is unemployed, which can be written as P(A|U). Using Bayes' theorem, we have:
P(A|U) = P(U|A) * P(A) / P(U)
We are given P(A) = 0.06 (6% of the labor force is Asian), P(U|A) = 0.05 (among Asians in the labor force, 5% are unemployed), and P(U|not A) = 0.06 (among non-Asians in the labor force, 6% are unemployed).
To find P(U), we can use the law of total probability:
P(U) = P(U|A) * P(A) + P(U|not A) * P(not A)
We know P(A) = 0.06, so P(not A) = 1 - P(A) = 0.94.
Therefore,
P(U) = 0.05 * 0.06 + 0.06 * 0.94 = 0.0602
Now we can substitute all the values into Bayes' theorem:
P(A|U) = 0.05 * 0.06 / 0.0602 = 0.0498
So the probability that a randomly selected member of the labor force is Asian given that he or she is unemployed is 4.98% (rounded to the nearest percentage with no decimal places).

The linear equation on the graph can be written as:
y = (3/4)*x - 1
How to write the linear equation?Here we have the graph of a linear equation, these are written as:
y = mx + c
Where m is the slope and c is the y-intercept.
On the graph we can see that the line intercepts the y-axis at y = -1, then we can write:
c = -1
So the linear equation is:
y = mx - 1
Looking at the graph we can see that the line also passes through the point (4, 2).
Replacing that in the linear equation we will get:
2 = m*4 - 1
2 + 1 = m*4
3 = m*4

The store sold 25% of its books over the holiday, and now it has 600 books in stock.
How many books the store had before holidays?
Answer: If the store sold 25% of its books during the holiday, that means it has 75% of its books left in stock after the holiday. Let's represent the original number of books with the variable "x".
So, if 75% of x is equal to 600 books, we can write an equation:
0.75x = 600
To solve for x, we can divide both sides by 0.75:
x = 600 / 0.75
x = 800
Therefore, the store had 800 books before the holiday.

What is the value of sin−1(−3√2)
Answer:
The value of sin^-1(-3√2) is an angle whose sine is -3√2.
Since the sine function is an odd function, sin(-θ) = -sin(θ), we can find the reference angle by taking the inverse sine of the positive value 3√2, which gives:
sin^-1(3√2) ≈ 80.06°
The sine function is also negative in the third and fourth quadrants of the unit circle. Since the given value is negative, the angle must lie in either the third or fourth quadrant.
To determine in which quadrant the angle lies, we can use the fact that sine is negative in the third and fourth quadrants. Since sin^-1(-3√2) gives a positive value, the angle must lie in the third quadrant where the sine is negative.
Therefore, sin^-1(-3√2) = -80.06° (rounded to two decimal places).

The percentage decrease in total principal and interest paid between a 30-year term mortgage and a 15-year mortgage with an APR of 6.5% and a principal balance of $242,300.00 is about 31.1%
What is an APR?An APR is an acronym for the Annual Percentage Rate, which is the interest on al loan amount expressed as a percentage of the amount on loan annually.
The loan amount, the annual percentage rate, and the term of the loan are presented as follows;
Loan amount, P = $242,300.00
Term of the loan, t = 30 years and 15 years
Annual Percentage Rate (APR), r = 6.5%
The amount of the loan after the period can be obtained by using the formula;
A = P·(1 + r)^t
The amount of each loan can therefore be calculated as follows;
The monthly payment is; M = P·(r·(1 + r)^t)/((1 + r)^t - 1)
M = 242,300×((0.065/12) × (1 + (0.065/12))^(30×12))/((1 + ((0.065/12)))^(30×12) - 1) ≈ 1531.5
The total payment on the 30-year loan ≈ 360 × 1531.5 = 551,340
The monthly payment for the 15-year loan is therefore;
M = 242,300×((0.065/12) × (1 + (0.065/12))^(15×12))/((1 + ((0.065/12)))^(15×12) - 1) ≈ 2110.7
The total payment on the 15-year loan ≈ 360 × 2110.7 = 379962
551,340
The percentage change is therefore;
((551,340 - 379962)/551,340) × 100 ≈ 31.1%
