Answer:
1 mile/hour is equivalent to 1.47 feet/seconds
Step-by-step explanation:
Given

Required
Determine the equivalent of 1 mile/hour

Express 60 as 60 * 1

Divide both sides by 60


Reorder

Divide 88 by 60

Approximate to 3 significant figures

Hence;
1 mile/hour is equivalent to 1.47 feet/seconds
Answer:
I believe the answer would be 1/6
Step-by-step explanation:
The work already says that there are 2 possible choices. This would be 2/12. This is further simplified to 1/6. Hope this helps
Answer:
a) The discriminant of the equation = - 44
b)The nature of the roots will be imaginary.
c) 
Step-by-step explanation:
Here, the given expression is 
or, 
Now the discriminant (D) of a quadratic equation 
D = 
Hence, the discriminant of the equation = - 44
As D< 0, so the roots will be imaginary.
Now,by quadratic formula : 
So, here 
So, either 
or, 
Step-by-step explanation:
you should only make one equation:
75 + 45x = 30 + 55x
subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:
45 = 10x
Divide by 10 and get:
4.5 = x
After 4.5 hours, the cost is equal for either worker.
