163,840,000,000 406 = 40 x 40 x 40 x 40 x 40 x 40 = 4,096,000,000.
Some multiples of 40 are: 2 x 40 = 80 3 x 40 = 120 4 x 40 = 160 5 x 40 = 200 6 x 40 = 240 7 x 40 = 280 8 x 40 = 320 9 x 40 = 360 10x 40 = 400
1 x 40 = 40 2 x 20 = 40 4 x 10 = 40 5 x 8 = 40
40/x
x + 3x = 40 4x = 40 x = 10.
2 x 2 x 5 x 5 x 17 = 1700
1700 = 2 x 2 x 5 x 5 x 17
2 x 2 x 5 x 5 x 17 = 1700
0.8 x 1700 = 1360 80% of 1700 is 1360
2 x 2 x 5 x 5 x 17 = 1700
2 x 2 x 5 x 5 x 17 = 1700
22 x 52 x 17 = 1700
22 x 52 x 17 = 1700
68/100=x/25 68*25=1700 100x=1700 1700 divided by 100=17 x=17
1700 meters in 40 minutes or 1700/40 meters per minute = 170/4 = 42.5 meters per minute
100%= 17005%= 1700/100 x 5= 85
To calculate the total kWh usage for a month for a space of 1700 square feet limited to 40 watts per square foot, you first multiply the area by the wattage limit (1700 sq ft x 40 Watts/sq ft). This gives you the total power input in watts in that space. Then divide this by 1000 to convert watts to kilowatts and multiply by the number of hours in a month (typically 720 hours) to get the total kWh usage.
