x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.
Answer:
5 times shorter
Step-by-step explanation:
The period is the time it takes for one cycle to complete, or in this case, one breath. Since person A is breathing 5 times faster, the time per breath is 5 times shorter.
7900 should be the answer, is there any options?
Answer:
The temperature of the part won’t reach or exceed 141℉
Step-by-step explanation:
Substituting the value of T= 141 the given equation becomes
we know that discriminant D = 
Three conditions: - D < 0: imaginary roots, D = 0: real and equal roots,
D > 0: two real and unequal roots Substituting a = -0.005, b = 0.045 and c = -16, 
Therefore, it won't reach the temperature.
1/2 hour = 60 min / 2 = 30 min
1/3 hour = 60 min / 3 = 20 min
Answer is 30+20 = 50 min
