Answer: -11 degrees Celsius

Step-by-step explanation:

4:00 am = -16 degrees

You know that 4:00am is four hours after midnight and you know that the temperature decreases by 1.75 degrees every hour so during that time it has dropped by:

1.75x4=7 degrees

Because it is -16 at 4:00am, you know it was 7 degrees higher at midnight

-16+7=-11

It was -11 degrees at midnight

An example of consecutive odd integers is 23, 25, 27, and 29. Find four consecutive odd integers with a sum of 160. Show your wo
Andrew [12]
Step1: Define an odd integer.
Define the first odd integer as (2n + 1), for n = 0,1,2, ...,
Note that n is an integer that takes values 0,1,2, and so no.

Step 2: Create four consecutive odd integers.
Multiplying n by 2 guarantees that 2n will be zero or an even number.
Therefore (2n + 1) is guaranteed to be an odd number.
By adding 2 to the odd integer (2n+1), the next number (2n+3) will also be an odd integer.

Let the four consecutive odd integers be
2n+1, 2n +3, 2n +5, 2n +7 

Step 3: require that the four consecutive integers sum to 160.
Because the sum of the four consecutive odd integers is 160, therefore
2n+1 + 2n+3 + 2n+5 + 2n +7 = 160
8n + 16 = 160
8n = 144
n = 18

Because 2n = 36, the four consecutive odd integers are 37, 39, 41, 43.

Answer: 37,39,41,43

If 1 megabyte is equal to 10^6 bytes and 1 gigabytes is equal to 10^9 bytes, how many gigabytes are there in 1 megabyte?
Finger [1]

Answer:

The answer is 1^{-3}

Step-by-step explanation:

To find how many gigabytes there are in 1 megabyte, we need to divide 1 megabyte by one gigabyte.

\frac{10^{6}}{10^{9}}

To divide exponents, you subtract them.

\frac{10^{6}}{10^{9}}=10^{-3}

Then divide 10/10.

\frac{10^{6}}{10^{9}}=1^{-3}

Your answer is 1^{-3}. (which equals 0.001)

I hope this helps! :)
