Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students

What is the exact value of x?
boyakko [2]

Answer:

B

Step-by-step explanation:

5\cdot 21^{5x} = 16 \\\ 21^{5x} = \frac{16}{5} \\\\ 21^{5x} = 3.2 \\\ log 21^{5x} = log 3.2 \\\ 5x\cdot log 21 = log 3.2 \\\ 5x = \frac{log 3.2}{log 21} \\\\\ x = \frac{log 3.2}{5\cdot log 21}


I hope I helped you.

Alexis is a lawyer. She bills her clients $100 an hour for her services. She can also mow her lawn in 30 minutes. She can hire s
Papessa [141]

Answer:

b) $49

Step-by-step explanation:

The question here is not if Alexis can mow the lawn faster or slower than the person who hires (actually, the time that the person hired took to mow the lawn is irrelevant).

The important part is the time Alexis can save hiring someone:

  • Alexis mow her lawn in 30 minutes.
  • Alexis earns $100 an hour. Then 30 minutes of her time is worthy $50.

Then, paying $50 or less is a good choice for Alexis.

Therefore the answer is b) $49.
