362 miles
213 miles
149 miles
63 miles
To find the total number of miles from home at the end of the second day, we need to add the distance traveled on the first day to the distance traveled on the second day. The distance traveled on the second day is 149 miles farther than the distance traveled on the first day. Therefore, the total distance traveled on the second day is 213 miles + 149 miles = <<213+149=362>>362 miles. Thus, at the end of the second day, Roberto is 362 miles from home. So the answer is 362 miles. Answer: \boxed{362 \text{ miles}}.

Ally's hotel room is on the 12th floor. She parked her car in the underground parking garage 4 floors below ground level. How many floors did Ally travel in the elevator to get from her car up to her room?
*
1 point
-8 floors
16 floors
8 floors
-16 floors
To find the number of floors Ally traveled in the elevator, we need to calculate the difference between the floor her car is parked on (4 floors below ground level) and the floor her hotel room is located on (12th floor).
Since the car is parked 4 floors below ground level and the hotel room is on the 12th floor, we can find the difference by subtracting the floor the car is parked on from the hotel room floor: 12 - (-4) = 12 + 4 = 16.
Therefore, Ally traveled 16 floors in the elevator to get from her car up to her room. The answer is: 16 floors.
Lynn had overdrawn her checking account 3 days in a row after the balance reached $0. Each day she took out $15 without realizing what had happened. Which of the following would appear on a bank statement representing the amount currently in her account since she spent more than she had?

1 point
-$5.00
-$18.00
-$45.00
-$12.00
Lynn overdraws her checking account by $15 each day for 3 days in a row. This means that on each of those days, her account balance will be $15 less than it was the previous day. Since her balance reached $0, this means that after the three days of overdrawn transactions, her account balance will be: $0 - ($15 + $15 + $15) = $0 - $45 = -$45.
Therefore, the amount that would appear on a bank statement representing the amount currently in her account is -$45. The answer is: -$45.
Which of the following cannot be used to describe -144 divided by -12?
*
1 point
negative
rational number
integer
whole number
The answer is "whole number".
When dividing -144 by -12, the result is a positive number, 12. Therefore, the result is not a whole number because whole numbers include only non-negative integers.
To find out how many miles from home Roberto is at the end of his second day, we need to add the distance he traveled on the first day to the additional distance he traveled on the second day.
On the first day, Roberto drove 213 miles.
On the second day, he drove 149 miles farther than the first day. This means he drove 213 + 149 = 362 miles on the second day.
To find out how many miles from home Roberto is at the end of his second day, we add the distance he traveled on the first day (213 miles) to the distance he traveled on the second day (362 miles).
213 miles + 362 miles = 575 miles.
Therefore, Roberto is 575 miles from home at the end of his second day.
