$x=2.070707\ldots=2.\overline{07}$
$100x=207.070707\ldots=207.\overline{07}$
$100x-x=99x=205\implies x=\dfrac{205}{99}$

The same architect wants to draw a room that has an area of 175 ft². What will be the area of the room in his drawing in square

Dominik [7]

Answer:

25,200in²

Step-by-step explanation:

The architect wants to draw a room that has an area of 175 ft². We need to find this measurement in square inches.

<u>Square feet and square inches are different from feet and inches. </u>

We should know that a square foot is 144 square inches.

Multiply 175 * 144.

$175 * 144=25200$

So the same architect wants to draw a room that should have an area of 25,200in².

A wire 48 m long carries a current of 18 A from west to east.

Arisa [49]

Step-by-step explanation:

Given that,

The length of a wire, L = 48 m

Current in the wire, I = 18 A (west to east)

The magnetic field in the wire, B = $8.3\times 10^4\ T$ (towards south)

The magnetic force acting on the wire is given by :

$F=I(L\times B)\\\\F=48\cdot18\cdot8.3\cdot10^{-4}\ N\\\\F=0.71\ N$

Using right hand rule, the direction of magnetic force is upwards.
