Let's solve each problem step by step:
---
Problem 1:
How cold will it get if it is 7°C outside and the temperature drops by 19°C in the next six hours?
#### Solution:
- Initial temperature: \( 7^\circ \text{C} \)
- Temperature drop: \( -19^\circ \text{C} \)
To find the new temperature, subtract the drop from the initial temperature:
\[
7 + (-19) = 7 - 19 = -12
\]
#### Answer:
\[
\boxed{-12}
\]

Problem 2:
Cara has $4,000 in her bank account. She spends $1,000 for her admission and $200 for buying accessories. How much money is left with her?
#### Solution:
- Initial amount: $4,000
- Amount spent on admission: $1,000
- Amount spent on accessories: $200
Total amount spent:
\[
1,000 + 200 = 1,200
\]
Remaining amount:
\[
4,000 - 1,200 = 2,800
\]
#### Answer:
\[
\boxed{2800}
\]

Problem 3:
Suppose your office elevator was initially on the 12th floor. It goes down 11 floors and then goes up 5 floors. Find on which floor one can find the elevator.
#### Solution:
- Initial floor: 12
- Floor change (down 11 floors):
\[
12 - 11 = 1
\]
- Floor change (up 5 floors):
\[
1 + 5 = 6
\]
#### Answer:
\[
\boxed{6}
\]

Problem 4:
Mr. Roberts makes 4 withdrawals of $10 each. How much has he withdrawn in total?
#### Solution:
- Number of withdrawals: 4
- Amount per withdrawal: $10
Total amount withdrawn:
\[
4 \times 10 = 40
\]
#### Answer:
\[
\boxed{40}
\]
---
Problem 5:
A number added to 5 is equal to -11. Find the number.
#### Solution:
Let the unknown number be \( x \). According to the problem:
\[
x + 5 = -11
\]
To solve for \( x \), subtract 5 from both sides:
\[
x = -11 - 5
\]
\[
x = -16
\]
#### Answer:
\[
\boxed{-16}
\]

Final Answers:
1. \(\boxed{-12}\)
2. \(\boxed{2800}\)
3. \(\boxed{6}\)
4. \(\boxed{40}\)
5. \(\boxed{-16}\)
