The loudness of sound in decibels perceived by the human ear depends on the intensity levels according to
D=10log(I/lo)
Find the decibel level when I is 63, 096 times Io.
The decibel is -------------- dB when I is 63, 096 times Io.
Round your answer to the nearest whole number.
Answer:
We can use the given formula to calculate the decibel level D when the intensity level I is 63,096 times Io:
D = 10log(I/lo)
Where Io is the reference intensity level and is typically taken to be the threshold of hearing, which is 10^−12 watts/m^2.
So, substituting the values, we get:
D = 10log(63,096*Io/Io) = 10log(63,096)
Using a calculator, we find:
D ≈ 47.1 dB
Rounding this to the nearest whole number, we get:
The decibel level is 47 dB when I is 63,096 times Io.
I hope this helps mate.
Pls help Darnell is an election officer. On election day, he travels to the polling place, which is 4.4 miles away from his home. On a map of Harrison County, these two places are 8 inches apart. What is the scale of the map? Write your answer in simplest form using whole numbers.
Answer:
The scale of the map is 1 : 34848---------------------------------
Real distance is 4.4 miles and on the map it is 8 inches.
The scale is:
8 in : 4.4 miles = Divide both sides by 81 in : 0.55 milesor
1 in : 0.55 * 63360 in = Convert 1 mile = 63360 inches1 : 34848solve 2x+ 4 1/5=9. explain the steps and properties you used. PLEASE ANSWER QUICKLY REALLY NEEDED
Answer:
2.4
Step-by-step explanation:
Cover the 4 1/5 = 21/5 = 4.2
2x + 4.2 = 9
Subtracting 4.2 from both sides
2x = 4.8
Dividing 2 from both sides.

The measure of the angle m∠PBM is calculated as; 54°
How to find the measure of the interior angle of an arc?An inscribed angle is defined as an angle with its vertex on the circle.
The measure of an inscribed angle is half the measure the intercepted arc.
The formula is:
Measure of inscribed angle = 1/2 × measure of intercepted arc
Now, we are given that;
MB = PB
Arc PB = 27°
Thus;
Arc MBP = 2 * 27°

Explanation:
If y is the short leg of the 30-60-90 triangle, then y*sqrt(3) is the length of the longer leg. The short leg is always opposite the shortest angle.
We're given that 5*sqrt(3) is the longer leg, so
y*sqrt(3) = 5*sqrt(3)
y = 5
After we divide both sides by sqrt(3)
Side note: x = 2y = 2*5 = 10.

Heya mate!
If you observe the figure, the longest side always resides the opposite place of the right angle. Accordingly the perpendicular is 5√3 units in measure.
With this, the hypotenuse is x and the base is y. We need to find y. By doing some smart work! Let's guess the trigonometric ratio that we give us the relation between y and 5√3 because one of the angle given is 60°
⇛ tan a = Perpendicular / Base
Plugging the values of a, and Perpendicular to find the base of the triangle i.e. y.
⇛ tan 60° = 5√3 / y
⇛ √3 = 5√3 / y
⇛ y = 5√3 / √3
⇛ y = 5 units
Hence, the Correct Option is Option A.
exercise 2-20 (static) record transactions, post to t-accounts, and prepare a trial balance (lo2-4, 2-5, 2-6)
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).
