Answer:
Based on the answers I can see, it'd be all of them.
Step-by-step explanation:
When rounding to the nearest hundred, you round down if the tens are 49 or smaller (e.g. 401 to 400). If the tens are 50 or bigger, you round up (e.g. 351 to 400). I hope that helps you.

Answer:
9000000
Step-by-step explanation:
you do 4*10000 to get 40000 then multiply that by 225
Part B:If Maura continues to drive at her increased speed, write an equation to find the total distance,d, in miles,that Maura will have travelled for any time,x, in hours, longer than 2 hours.
Part C:Using the equation from Part B, how far would Maura travel in 5 hours?
The answer for part (a) is 75 miles/hour, for part (b) is 75h = d, and for part (c) is 375 miles.
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
On a road trip, Maura drove at a speed of 60 miles per hour for the firsttwohours. she then increased her speed by 25%.
Total miles = 60×2 = 120 miles in two hours
= 25% of 60 = 15
= 60 + 15 = 75 miles/hours
The equation:
75h = d (distance = speed×time)
Plug h = 5
75(5) = d
d = 375 miles
Thus, the answer for part (a) is 75 miles/hour, for part (b) is 75h = d, and for part (c) is 375 miles.
