Question

Can somebody please help me with sig figs for this question

Answer 1

760
`(cW)/(micrograms)`

Step-by-step explanation:

You have to know that:

• 1 gigawatt (GW)=100000000000 centiwatt (cW)
• 1 kilogram (kg) = 1000000000 micrograms (μg)

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

So:

`x=(c*b)/(a)`

In this case, you have
`(760 GW)/(1 kg)`

In this case, the rule of three is applied as follows: if 1 gigawatt [GW] = 100000000000 centiwatt [cW], 7.600 GW how many cW are they?

`(7.600 GW)/(kg) *(100000000000 cW)/(1 GW) *(1 kg)/(1000000000 micrograms)=760 (cW)/(micrograms)`
