Converting units is always an exercise in linear relationships. how many inches is 2.50 m? (2.54 cm=1.0 inch)
madam [21]

There are 98.4252 inches in 2.50m.

Unit Conversion is defined as a process that involves multiplication and division by a numerical factor or a particular conversion factor.

For Example .Convert 2m into cm.

As we know that 1m=100cm

multiplying both sides by 2 we get

2m = 200 cm.

According to the question

It is given that 2.54 cm = 1 inch

1cm = \frac{1}{2.54} inch

100cm=\frac{100}{254} inch

1m = \frac{100}{2.54} ( as 100cm = 1m)

we need 2.50 m So we multiply both sides by 2.50

2.50m=\frac{2.50*100}{2.54} \\\\  2.50m=\frac{250}{2.54}

2.50m=98.4252 inch

Therefore , there are 98.4252 inches in 2.50m.

Answer:

<h2>2 + 2i</h2>

Step-by-step explanation:

i-\text{imaginary\ unit}\\\\i=\sqrt{-1}\to i^2=-1\\\\=====================

\dfrac{10-10i}{-5i}=\dfrac{10}{-5i}+\dfrac{-10i}{-5i}=\dfrac{(10)(i)}{(-5i)(i)}+2=\dfrac{10i}{(-5)(i^2)}+2\\\\=\dfrac{10i}{(-5)(-1)}+2=\dfrac{10i}{5}+1=2i+2=2+2i
