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.

Max has a science test on Thursday. On Monday he studied 2/9 of the material. On Tuesday he studied 1/4 of the remaining materia

wolverine [178]

Answer:

The answer to your question is:

Fraction he has review = 17/36

Fraction he have to study = 19/36

Step-by-step explanation:

Data

Monday studied = 2/9

Tuesday = 1/4

Fraction he has review = ?

Fraction he has left = ?

Process

As the denominator is 9, consider the whole is 9.

Then: Fraction left on Monday = 9/9 - 2/9

= 7 / 9

Fraction left on Tuesday = 7/9 - 1/4

= (28 - 9) / 36

= 19 / 36

Fraction he has review = 17/36

Fraction he have to study = 19/36
