The temperature at night reached -13 F. Write an equivalent statement about the temperature using the absolute value of the numb
Sergio [31]
The kelvin scale is the standard absolute thermodynamic temperature scale.
Therefore, this question is simply asking you to convert the degree fahrenheit into degree kelvin.

The formula used to convert between kelvin and fahrenheit is as follows:
T(K)<span> = (</span>T(°F)<span> + 459.67) × 5/9
</span>
We will substitute in this equation with T(F)=-13 and calculate T(K) as follows:
t(K) = (-13 + 459.67) x 5/9 = 248.15 K

Based on this, the previous sentence can be written using absolute value of the number as follows:
The temperature at night reached 248.15 K.

Answer:

1. 62

2. 13

3. 6

4. 18

5. 3

Step-by-step explanation:

1. Let's use pemdas

16*1/2= 8

32 / 4 * 8 - 2

8*8 - 2

64 - 2

= 62

2. Let's use pemdas

5*2/5 = 2

20 / 2 + 3

10 +3

= 13

3. Let's use pemdas

1/2 * 24 / 3 +2

12 / 3 +2

4 +2

=6

4. Let's use pemdas

2 * (6 / 2 + 8) -4

2 * 11 - 4

22 - 4

= 18

5. Let's use pemdas

(28 / 7 +6 / 3) * 1/2

( 4 + 2) *1/2

6 *1/2

= 3

How many three-digit positive integers have three different digits and at least one prime digit?
Blababa [14]

The number of three-digit positive integers that have three different digits and at least one prime digit are 7960.

The only two components in prime numbers are 1 and the number itself.

Any whole number greater than one is a prime number.

It has exactly two factors—1 and the actual number.

There is just one 2-digit even prime number.

Every pair of prime numbers is always a co-prime.

The product of prime numbers can be used to represent any number.

Three-digit positive integers that have three different digits and at least one prime digit = 3!*4!*10*9 = 7960
