Answer:
2, 3, 6
Step-by-step explanation:
Simply try each value using long division.
2:
Since 5,238 ends in an even number, that automatically means it is divisible by 2.
5238/2=2619
Now for 3:
5238/3=1746 no remainder or decimal, so 3 also works
4:
You can either do long division again with 4, or you can see if 5238 divided by 2 (5238/2) is also divisible by 2. Since 2619 doesn't end in an even number, 4 is a no go.
Long division 5238/4=1309.5 decimal here, so 4 isn't an answer
5:
This is also very easy, simply check if the number ends in 0 or 5. Since 5,238 does not, 5 doesn't work either.
6:
You can do the same thing as with 4, except this time trying to find if 5238 divided by 3 (5238/3) is divisible by 2. Since 1746 ends in an even number, 6 also works.
Long division: 5238/6=873
9:
You can do the same thing as with 6, except this time trying to find if 5238 divided by 3 (5238/3) is divisible by 3.
1746/3=548 with a remainder of 2, which means 9 doesn't work
Long division: 5238/9=548.66 repeating
10:
Finally, 10 is another easy one. Simply check if the number ends in 0. 5,238 does not, so 10 doesn't work.

The perimeter of a rectangle with length l and width w is 44 inches. The area of the rectangle is at most 120.
Which of the following statements is true?
A. If w 12 inches, then l 10 inches
B. If w 12 inches, then l 10 inches
C. If w 12 inches, then l 10 inches
D. If w 12 inches, then l 10 inches
The true statement about the rectangle is A. If w is 12 inches, then l is 10 inches
How to determine the true statement?The given parameters are:
Perimeter, P = 44Area = 120 (at most)The perimeter of a rectangle is:
P = 2(L + W)
So, we have:
2(L + W) = 44
Divide by 2
L + W = 22
The area is calculated as:
A = LW
This gives
LW = 120
Express 120 as 12 * 10 and 10 * 12
LW =12 * 10 or LW = 10 * 12
By comparison, we have:
L = 12 and W = 10 or L = 10 and W = 12
When these values are substituted in L + W = 22, we have:
10 + 12 = 22 and 12 + 10 =22
This means that the dimensions of the rectangle are 10 by 12 inches or 12 by 10 inches
Hence, the true statement is A. If w is 12 inches, then l is 10 inches

We can see there are brackets. When a number is placed near a bracket, it means we need to multiply.
2 x 3 = 6
Let's check our expression.
5 - 6 + 6
We can see that there is addition and subtraction. When we have addition and subtraction together we can solve left to right. The same applies to multiplication and division.
So let's solve the rest of it.
5 - 6 = -1
-1 + 6 = 5

nth term for 300,250,200
The nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have an arithmetic sequence:
300,250,200
The first term a = 300
Common difference d = 250-300 = -50
nth term:
A(n) = a + (n-1)d
A(n) = 300 + (n-1)(-50)
A(n) = 300 -50n + 50
A(n) = 350—50n
Thus, the nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

What is the mass of 35 moles of CO₂?
A store manager wants to estimate the proportion of customers who spend money in this store. How many customers are required for a random sample to obtain a margin of error of at most 0.075 with 80% confidence?
The 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.
What is the margin of error(MOE)?MOE is an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
MOE = z x s/√n
Where ,
Z = the z-score at the confidence interval
s = the standard deviation
n = the number of samples.
We have p = 0.50 MOE = 0.075
Z = 1.282 at 80% confidence
0.075 = 1.282 x √0.50(1- 0.50)/ n
After solving,
n = (0.5)(0.5)/(0.0585)²
n = 73
Thus, the 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.

b. The allowance account before adjustment has a debit balance of $11,400. An aging of the accounts in the customer ledger indicates estimated doubtful accounts of
$36,500.
c. The allowance account before adjustment has a credit balance of $4,700. Bad debt expense is estimated at 1/2 of 1% of sales.
d. The allowance account before adjustment has a credit balance of $4,700. An aging of the accounts in the customer ledger indicates estimated doubtful accounts of

Determine the amount of the adjusting entry to provide for doubtful accounts under each of the assumptions (a through d) listed above.
Based on the account receivable balance and the adjustments, the adjusting entries for doubtful debt under various assumptions is:
a. $23,900b. $47,900c. $47, 800d. $34,300What are the entries for doubtful debt?a. Bad debt is 1/4 of 1% of sales:
= 9,560,000 x 0.25%
= $23,900
b. Debit balance of $11,400:
= Estimated doubtful accounts + Debit balance
= 36,500 + 11,400
= $47,900
c. Credit balance of $4,700 and 1/2 of 1% of sales:
= Sales x 0.50%
= 9,560,000 x 0.50%
= $47,800
