First you need each side of the ratio to be in the same units.
The easiest way to do that is to convert 1 hour into minutes.
1 hour=60minutes
So your ratio is now 60:45
Now you need a common factor that goes into both 45 and 60.
15 is the greatest common factor so now divide each side by 15.
45÷15=3
60÷15=4
The ratio, in its simplified for is 4:3

A cone has a diameter of 3 inches. The cone holds 12 cubic inches of water. To the nearest inch, what is the height of the cone?
Cerrena [4.2K]
Use the equation for the volume of a cone to solve for the height:
V= \frac{1}{3} \pi r^{2}h \\
12= \frac{1}{3} \pi *2.25h \\
h=5.096 inches

DaniilM [7]
Given:
7 kg turkey

cooking instructions:
over 4kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving.

7kg * 20 minutes/kg = 140 minutes

140 minutes + 90 minutes = 230 minutes
230 minutes + 30 minutes rest = 260 minutes

260 minutes * 1hr/60 minutes = 4 hours 20 minutes

17:15 is 5:15 pm

17:15 - 4:20 = 12:55 pm

Adam should start cooking at 12:55 pm
