21=1/2h(2+5)
21=1/2h+7
21
-7
14=1/2h
14 divided by 1/2 equals 28
h=28
Answer:
This is equation of ellipse
Step-by-step explanation:
we are given
We can see that right side is 36
so, we can make right side as 1 by dividing both sides by 36
we can simplify it
we can rewrite it as
now, we can compare it with standard equation of ellipse
we can see that both equations are similar
so, this is equation of ellipse
Answer:
In the new mixture, the percentage of water with respect to its total is 13.33%.
Step-by-step explanation:
Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:
20 + 80 + 50 = 150
150 = 100
20 = X
((20 x 100) / 150) = X
2,000 / 150 = X
13.33 = X
Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.
Round both numbers! :)
498 would round to the nearest hundred, 500 and 12 would round to the nearest ten, 10
You can then divide 500 and 10 which gets you 50.
Hope this helped :)
