9)order from least to greatest: |3|,|-5|,-8.56,-8,|-8| 11)which has more prime factors: 50 or 49? explain how you know

In most of the numbers, there are | |. That is the sign for absolute value. Absolute value is the distance from a number to 0. The sign doesn't matter.

Example: |-6| = 6 The distance between -6 and 0 is 6.

|3| = 3

|-5| = 5

-8.56 = -8.56

-8 = -8

|-8| = 8

Now order them. Remember that negative numbers are first. The greater negative numbers come first.

First list the factors of both numbers:

49 - 1, 7, 49

50 - 1, 2, 5, 10, 25, 50

The bold numbers are the prime factors. Prime numbers are numbers that have 2 factors - 1 and itself. 1 is NOT a prime number.

49 has 1 prime factor and 50 has 2 prime factors.

50 has more prime factors

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
