30×30=900
900/112.5=8 cameras to cover
112.5×4=450
900-450=450 ft left uncovered
The answer is 2
because 12 divided by 6 equals 2
Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
5/3 = 1.66667
1.666666^3=4.6296 (Volume is measured in cubic units)
54x4.6396=250
250 x pi = 250Pi.
The side opposite the lasrgest angle will also be the largest side in the triangle
Here it s 5.5 cms.
so using the given ratios we have
2/11 = x /5.5 where x is the smallest side (opposite the smallest angle)
x = (2*5.5) / 11 = 1 cm.
