A50 liter aquarium weighs 23 kilograms empty. what does it weigh when filled with 45 liters of water?

totalweight=tankweight+waterweight

tankweight=weight when empty=23kg

waterweight=45liters mass

1liter weighs 1kg, so 45liters weights 45kg

totalweight=23+45=68kg

because its not ur topic and its not for is for homework not that.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4
