Which expression is equivalent to:1/m6
Valentin [98]

Answer:

A

Step-by-step explanation:

6 is a power. So both C and D are wrong because 6 is being treated as an ordinary integer.

So the answer must be either A or B.

B is not correct because to move an expression from the denominator to the numerator changes the sign in the base (which is m in this  question).

A is correct. the power is changed from 6 in the denominator to -6 in the numerator. m is shifted to the numerator as well.

Which measure is equivalent to 25,200 seconds?<br><br> 1 min = 60 s<br><br> 1 h = 60 min
sertanlavr [38]

Solution:

<u>Note that:</u>

  • 1 min = 60 sec
  • 1 h = 60 min.

<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>

  • => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes

<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>

  • => 420 minutes = 420 ÷ 60 hours = 7 hours

<u>We can conclude that:</u>

  • 25,200 seconds = 420 minutes = 7 hours

If M∠ ABD =64 and M∠CBD=30 then M∠ABC= <br> Need help
Leno4ka [110]

Answer:

\displaystyle m\angle ABC = 34^\circ

Step-by-step explanation:

∠ABD is the sum of the angles ∠ABC and ∠CBD. In other words:

\displaystyle m\angle ABD = m\angle ABC + m\angle CBD

Substitute in known values:

\displaystyle \left(64^\circ\right) = m\angle ABC + \left(30^\circ\right)

And subtract. Hence:

\displaystyle m\angle ABC = 34^\circ

In conclusion, ∠ABC measures 34°.
