Question

Для подключения электричесива к садовому домику необходим провод длиной 29м47см на сколько см надо укоротить провод длиной 30м

Answer 1

30м. - 29м47см.= 53 см -- надо укоротить провод. 

Answer 2

0.53 метра поскольку 30 -29.47 равно 0.53

Answer 3

Calculating the Length of Shortened Wire

To calculate the length by which the 30m wire needs to be shortened to connect the electrical supply to the garden house, we can subtract the length of the wire available from the required length.

The calculation can be expressed as:

Shortened length = Required length - Available length

Substituting the given values: Shortened length = 30m - 29m 47cm

Calculation

Converting 29m 47cm to meters: 29m 47cm = 29.47m

Now, we can calculate the shortened length: Shortened length = 30m - 29.47m

Shortened length = 0.53m

Therefore, the wire needs to be shortened by 53cm to connect the electrical supply to the garden house.
