Question 4-6. Earth is 93 million miles from the Sun. Pluto is 4.67 billion miles from the Earth.Calculate the ratio of the distance from Pluto to Earth to the distance from Earth to the Sun. Use scientific notation to calculate the ratio and express your answer in standard notation. (round to the hundredths place)

PE/SE = 5.02×10¹

Step-by-step explanation:

Sun-Earth (SE) = 93×10⁶ miles

Pluto-Earth (PE) = 4.67×10⁹ miles

so, PE/SE = (4.67×10⁹) / (93×10⁶) = (4.67×10³)/93 =

= 50.215053763440860215... =

= 5.02×10¹ / 1 or simply 5.02×10¹

in other words, Pluto is a little bit more than 50 times farther away from Earth, than Earth is from the Sun.

d)  The possible value of n can be expressed as 15 < n < 25.

Step-by-step explanation:

Here, the given sides of the triangle are:

First Side  = 20 cm

Second Side = 5 cm

Third side  = n cm

Now ,as we know " SUM OF ANY TWO SIDES OF A TRIANGLE IS ALWAYS GREATER THAN THE THIRD SIDE"

⇒  Length of ( First + Second ) side > Third Side

or,( 20 cm + 5 cm ) > n cm

or, n < 25 cm

Now, from all given options,

15 < n < 25 is the MOST APPROPRIATE.

Hence, the possible value of n can be expressed as 15 < n < 25.
