Answer:

20 hours

Step-by-step explanation:

If the machine drilled 72 feet in 24 hours, we can divide 72 by 24 to find out that the machine drilled 3 feet in one hour.

Next, you must find the distance that must be traveled. You can do this by subtracting 72 from 132. You will get 60

So, if the machine drilled at 3 feet per hour, and it needs to drill 60 feet, it will take 20 hours because 60 divided by 3 is 20.

What is the solution to 4 superscript log subscript 4 baseline (x 8) baseline = 4 squared
Agata [3.3K]

The solution to 4 superscript log subscript 4 baseline (x 8) baseline = 4 squared for the variable <em>x </em>is 8.

<h3>What is the exponent of log rule?</h3>

The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.

For example, let <em>k</em> is the number and <em>a </em>is the base. Thus,

a^{\log a(k)}=k

The logarithmic equation given in the problem is,

4^{\log_4(x+8)}=4^2

Compare the equation with the expression of exponent of log rule, we get,

x+8=4^2\\x+8=16\\x=16-8\\x=8

Thus, the solution to 4 superscript log subscript 4 baseline (x 8) baseline = 4 squared for the variable <em>x </em>is 8.

Please help!!<br><br> Evaluate the expression for h = 14.<br><br> -51 + 13(-4h + 57)^2
Anna [14]

Answer:

-38

Step-by-step explanation:

-51 + 13(-4h + 57)^2

  • Subsitute the value of h into the variable.

-51 + 13 [-4(14) + 57]²

  • According to BEDMAS, solve the brackets first.

-51 + 13 (-56 + 57)²

-51 + 13(1)²

-51 + 13(1)

-51 + 13

= -38

Erwin earns $ 2 , 100 per month. Her deductions amount to 26 % of her paycheck. How much does Erwin take home each month?
Sergeu [11.5K]

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.
