Yes, a roll-up mattress can be rolled up again. Most roll-up mattresses are designed to be easily compressed and rolled up for convenient storage or transportation. Once unrolled and allowed to expand, the mattress can be rolled up again by following the same process used for the initial roll-up. However, it's important to follow the manufacturer's instructions to ensure the mattress is rolled up properly and without causing any damage. **

To roll fondant over a frozen cake, first let the cake thaw slightly so that the surface is not too hard. Then, lightly brush the surface of the cake with a simple syrup or water to help the fondant adhere. Roll out the fondant on a smooth surface dusted with powdered sugar or cornstarch to prevent sticking. Carefully lift the rolled fondant using a rolling pin and drape it over the cake, smoothing it gently with your hands to remove any air bubbles or wrinkles. **

To prepare a sponge cake roll with frozen strawberries, start by thawing the strawberries and then slicing them into small pieces. Next, prepare the sponge cake batter and spread it onto a baking sheet lined with parchment paper. Bake the cake according to the recipe instructions and then carefully roll it up with the parchment paper while it's still warm. Once the cake has cooled, carefully unroll it and spread a layer of whipped cream or frosting onto the cake, followed by the sliced strawberries. Finally, carefully roll the cake back up and refrigerate it for at least an hour before serving. **

The probability of rolling an even number on a standard die is 3/6 or 1/2. When rolling the die twice, the outcome of the first roll does not affect the outcome of the second roll, so the probability of rolling an even number on the first roll remains 1/2. **

The probability of rolling a one on a fair six-sided die is 1/6. When the die is rolled 10 times, the probability of rolling a one exactly once can be calculated using the binomial probability formula. This probability is approximately 0.323, or 32.3%. Therefore, it is moderately likely to roll a one exactly once when a die is rolled 10 times. **

The SQL query for the Terra database will depend on the specific task or information you are trying to retrieve. However, a basic SQL query to retrieve all data from a table in the Terra database would look like this: ```sql SELECT * FROM table_name; ``` Replace "table_name" with the actual name of the table you want to retrieve data from. If you want to retrieve specific columns or apply filters, you can modify the query accordingly using the SELECT and WHERE clauses. **

The SQL query for a SQLite database is similar to other SQL databases. Here is an example of a simple SQL query for a SQLite database: ``` SELECT * FROM table_name; ``` This query selects all columns from the specified table in the database. Other common SQL queries for SQLite include INSERT, UPDATE, DELETE, and CREATE TABLE. **

Rolled-up mattresses can typically remain rolled up for a few months without causing any damage. However, it is best to unroll and use the mattress within a few weeks to prevent any potential long-term damage to the materials. Extended periods of being rolled up can cause the mattress to lose its shape and support, so it's best to unroll and use it as soon as possible. **
