Answer:
6 or 6 1\3 but i really think it is 6
Step-by-step explanation:
If the container is divided into 12ths you should make that your common denominator.
So 1/4 now equals 3/12
Since we want this 3/12 to be empty we must subtract it from 12/12 leaving us with 9/12.
When we subtract 2/12 from 9/12 to get the amount that was already filled we get 7/12 which is the amount that needs to be filled.
To check we add our parts 2/12 and 7/12 to get 9/12 which is 3/4 of the container filled leaving 3/12 or 1/4 of the container empty.
Hope this helps ☺
All this is a unit conversion really, initially you'll need to put the 460.28 oz over the 12.44 hours. Your expression should read as 460.28 oz/12.44 hr, next simply divide and you will have your answer of 37 oz/hr
Step-by-step explanation:
If ∠1 and ∠2 are supplementary, then m∠1 + m∠2 = 180° (1).
If ∠2 and ∠3 are supplementary, then m∠2 + m∠3 = 180° (2).
From (1) we have
m∠1 + m∠2 = 180° /<em>subtract m∠1 from both sides</em>
m∠2 = 180° - m∠1
<em>substitute it to </em><em>(2)</em>
(180° - m∠1) + m∠3 = 180°
180° - m∠1 + m∠3 = 180° <em>/subtract 180° from both sides</em>
- m∠1 + m∠3 = 0 <em>/add m∠1 to both sides</em>
m∠3 = m∠1 ⇒ m∠1 = m∠3 ⇒ ∠1 ≅ ∠3
