Thank you for posting your question here in brainly. The scientific notation of 0.000236 cubic meters is 2.36^-4. The Scientific notation is the way the scientists easily handle large numbers or the very small number. I hope my answer helps.
Juan's time = x
Yumi's time = x + 2
Yumi's distance = 3 miles
Juan's distance = 2 miles
Rate = distance/time
Juan's rate = 2/x
Yumi's rate = 3/(x + 2)
The rates are equal so:
2/x = 3/(x + 2)
2x + 4 = 3x
x = 4 hours
Yumi's time = 4 + 2 = 6 hours
The answer is D.
Answer: B
$30 + 0.18m < $55
Look at the signs!!!!
Additional mean add!
Less than <
M represent the number of miles
