Answer:
5:21
Step-by-step explanation:
We know that currently (in the problem) it is 25 min before 4, or 3:35. When we add an hour to that (first part of the problem), we get 4:35. The way l like to continue from here is to take the second part (the 46 min) and just use part of it to round the hour off, and then add the other part to it.
From 4:35 to 5, we have 25 min
4.35 + 25 = 5
We subtract those 25 min from the 46 min, since we used them to round the hour off.
46 - 25 = 21
We have 21 min left, and now that the hour is rounded off, it's way easier to add minutes to it.
5 + .21 = 5.21.
So an hour and 46 min from 3:35 it will be 5:21. I hope this helps :)
Answer:
<em>Gardener will need 4 more plants.</em>
Step-by-step explanation:
Gardener has 780 plants and wants to plant them in an array of n rows and n columns.
The number of plants needed to do that is:
He actually has 780 plants, thus it should occur:
Taking the square root:
n=27.9
Since n needs to be an integer, we round up n to get
n=28
But 
, 4 more than the actual number of plants, thus:
Gardener will need 4 more plants.
Note: There are other possible results for n. If we set n=29, then 
and Gardener would need 841-780=61 more plants, but the question asked for the minimum number of plants.
12 : 6 = 6 : 3 : 2 : 1
First blank = 6
Second blank = 2
Hope this helps. - M
