Answer:
3 hours and 50 minutes
Step-by-step explanation:
Given that
Sarah drives for 1 hours and 40 minutes
And, rest for 25 minutes
And, then drive for another 1 hour & 45 minutes
We need to find out the total travel time in hours and minutes
First we convert into minutes i.e.
= 1 hour + 40 minutes + 25 minutes + 1 hours + 45 minutes
= 60 minutes + 40 minutes + 25 minutes + 60 minutes + 45 minutes
= 230 minutes
i.e.
3 hours and 50 minutes
1.2x10^-4
When doing scientific notation the number can't be equal to or bigger than 10 so since it was 12 you had to move the decimal over one so ^-1 then since thousandth is .000 then you have to do ^-3 and then ^-1 + ^-3 is ^-4 and so it comes out 1.2x10^-4... in bad at teaching but hey now you know the answer
Answer:
No inequality given but in my view answer is:
x ≥ 16
Step-by-step explanation:
Given that:
Total time = 6 hours
Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)
Time required for 1 centerpiece = 15 mins
We have to find inequality for x:
Number of centerpieces she makes = x
In 240 mins : 240/15 centerpieces can be made
= 16 centerpieces
If she works with the same speed or more efficiently the suitable inequality would be:
x ≥ 16
I hope it will help you!
