Hello,
Addition : no because -1+(-1)=-2 not in set.
Division : no because 1/0 is not in the set :infinity
Multiplication yes: {-1,0,1}*{-1,0,1}={-1,0,1}
Substraction: No because (-1)-(1)=-2 not in set.
Answer C
Answer:
t=0.4 sec
Step-by-step explanation:
Remember that
1 mile=5,280 feet
1 hour=3,600 seconds
Let
s -----> the speed in ft/sec
d ----> the distance in ft
t -----> the time in sec
s=d/t
Solve for t
t=d/s
step 1
Convert miles/hour to ft/sec
105.1 mi/h=105.1(5,280/3,600)=154.15 ft/sec
step 2
Find the time
t=d/s
we have
s=154.15 ft/sec
d=60.5 ft
substitute
t=60.5/154.15
t=0.4 sec
Answer: A is the answer good luck :)
