<span>First find the area of the field A=WL A=(110m)(60m) A=6,600m^2 Now turn the cm into m becouse 100cm^3=1m^3 660,000,000cm^3=6,600,000m^3 Now find out how many times you can cover the filled 6,600,000m^3/6,600m^2=100m So it will be 100m thick. P.S. I'm assuming you meant you jest forgot the m for 110m.</span>
I just solved this one anothe way is undistribute the 2 first and move -14 to side 2(x^2+6x)-14=0 comlete the squer inside and add negative 2(x^2+6x+9-9)-14=0 factor perfect square 2((x+3)^2-9)-14=0 distribute 2(x+3)^2-18-14=0 2(x+3)^2-32=0 add 32 both sides 2(x+3)^2=32 divide 2 (x+3)^2=16 sqrt both sides x+3=+/-4 minus 3 x=-4-3 or 4-3 x=1 or -7
Since we aren't given any further information in the question, the best time for the race based on the information given will be the addition of the top speed for each leg. This will be:
= 56.81 + 59.22 + 57.39 + 60.11
= 233.53 seconds
Therefore, the best time for the race is 233.53 seconds.
