What is the value of the logarithm?
sweet-ann [11.9K]

Answer:

3.9512

Step-by-step explanation:

You can find the answer by simply putting the value of natural log in a calculator.

ln (52) = 3.951243719

ln (52) = 3.9512 (rounding to nearest 10000th)

Which is the value of natural log of 52 rounded to the nearest ten thousandth

__________________________________________________________

<em>Note: To round off, we will see the number after the 10000th is greater than 5 or not, since the number is 4 and it is less than 5 so we will not raise the 10000th number which is 2</em>

Tickets to a Broadway show cost $35 for adults and $10 for children. The total receipts for 1650 tickets at one performance were
Dvinal [7]

Answer:1010 adult tickets and 640 child tickets were sold

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of child tickets that were sold.

The total number of tickets sold was 1650. This means that

x + y = 1650

Tickets to a Broadway show cost $35 for adults and $10 for children. The total receipts for 1650 tickets at one performance were $41,750. This means that

35x + 10y = 41750 - - - - - - - - - -1

Substituting x = 1650 - y into equation 1, it becomes

35(1650 - y) + 10y = 41750

57750 - 35y + 10y = 41750

- 35y + 10y = 41750 - 57750

- 25y = - 16000

y = - 16000/-25

y = 640

x = 1650 - y = 1650 - 640

x = 1010
