When decimals have zeros does the zero have a value

Step-by-step explanation:

If there is zero before decimal ,

then it must have values.

Like,  200.4

Here, the zeros in one's and tenth places have values.

Now, for the zeros after decimal,

there are two cases-

If the zero is after decimal and there is no digit after this zero,

then this zero will not have any value.

like,  125.0

this zero have no value.

Now, if the zero is after decimal, but there are other digits after this zero,

then this zero must have value.

like, 125.03

this zero have value, since there is a digit 3 after the zero.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
