Answer:

The required expression is either 23°F - (-8°F) and the temperature increased by 31°F.

Step-by-step explanation:

At midnight, the temperature was -8°F. At noon, the temperature was 23°F.

We need to find the expression that represents the increase in temperature.

Increase in temperature = Temperature at noon - Temperature at midnight

Increase in temperature = 23°F - (-8°F)

Increase in temperature = 23°F + 8°F

Increase in temperature = (23+8)°F

Increase in temperature = 31°F

Therefore the required expression is either 23°F - (-8°F) and the temperature increased by 31°F.

Answer:

23^oF-(-8^oF)

Step-by-step explanation:

We have been given that at midnight, the temperature was -8^oF. At noon, the temperature was 23^oF.

Since our temperature has increased to 23 degree Fahrenheit from -8 degree Fahrenheit, we can represent this increase in temperature as:

\text{The increase in temperature}=23^oF-(-8^oF)

Therefore, the expression 23^oF-(-8^oF) represents the increase in temperature.

I have 7 hundreds blocks, 5 tens blocks, and 8 ones blocks. I use my blocks to model two 3-digit numbers. What could my two numb
lawyer [7]
There 7 blocks of hundreds which means each such block is equivalent to 100.
There are 5 blocks of tens, which means each such block is equivalent to 10.
There are 8 blocks of ones, which means each such block is equivalent to 1.

The total of these blocks will be = 7(100) + 5(10) + 8(10) = 758

We can make several two 3-digit numbers from these blocks. An example is listed below:

Example:
Using 3 hundred block, 2 tens blocks and 4 ones block to make one number and remaining blocks to make the other number. The remaining blocks will be 4 hundred blocks, 3 tens blocks and 4 ones blocks
The two numbers we will make in this case are:

1st number = 3(100) + 2(10) + 4(1) = 324
2nd number = 4(100) + 3(10) + 4(1) = 434

The sum of these two numbers is  = 324 + 434 = 758
i.e. equal to the original sum of all blocks.

This way changing the number of blocks in each place value, different 3 digit numbers can be generated.
