A ten-minute mile is 62% of a factor so you'd use this mans weight and then multiply it by .62. (174)(0.62)=107.88
1 kilometer = 1000 meters.
Multiply total kilometers by 1000:
108 kilometers x 1000 = 108,000 meters.
1 hour = 3600 seconds.
Divide total meters by 3600:
108,000 / 3600 = 30 meters per second
Multiply 30 meters per second by 15 seconds:
30 x 15 = 450 meters in 15 seconds.
Hi,
1) ax²+2bx+c=0 have real roots then (2b)²-4ac>=0 ==> 4b²>=4ac ==> b²>=ac
2) bx²-2√(ac)x+b=0 have real roots then
(-2√(ac))²-4b²>=0==> 4ac>=4b²==> ac>=b²
So b²>=ac>=b²==> b²=ac
Answer:
Step-by-step explanation:
d) 48 is a factor of 144 as 48 multiplied by 3=144
Answer:
1206 = 1000 + 200 + 0 + 6
1000 * 5 = 5000
200 * 5 = 1000
6 * 5 = 30
5000 + 1000 + 30 = 6030
So, 1206 * 5 = 6030
Sorry I took so long.
Hope this helps!
