anastassius [24]

Answer:

-113

Step-by-step explanation:

Let's use the Decomposition Method.

1) Use this rule: $-a-b=-(a+b)$ .

$-(83+30)$

2) Use the decomposition method.

$83 = 80 + 3$

$30 = 30 + 0$

_____________________

$110 + 3 = 113$

3) After simplification, we have:

$-(83+30)=-113$

4) Therefore, $-83-30=-113$ .

$-113$

light travels 3000000 scs if earth is 150 million km away from sun how many minutes it will take the light to come from sun to e

sweet-ann [11.9K]

Speed of light=3×10^8m/s=3×10^5km/s
Distance=150million km=150×10^6km

Now

$\\ \rm\longmapsto Speed=\dfrac{Distance}{Time}$

$\\ \rm\longmapsto Time=\dfrac{Distance}{Speed}$

$\\ \rm\longmapsto Time=\dfrac{150\times 10^6}{3\times 10^5}$

$\\ \rm\longmapsto Time=50\times 10^1$

$\\ \rm\longmapsto Time=500s$

$\\ \rm\longmapsto Time=8.33min$

Can be written as 8min 20s.
