Question

Astronomers classified the planets into six sizes with five atmosphere types and four average temperature ranges. How many different planet types are there?

a) 60
b) 120
c) 150
d) 180

Answer 1

There are 120 different planet types based on their sizes, atmosphere types, and average temperature ranges.

Step-by-step explanation:

Astronomers classified the planets into six sizes with five atmosphere types and four average temperature ranges. To determine the number of different planet types, we multiply the number of sizes (6) by the number of atmosphere types (5) and then multiply the result by the number of average temperature ranges (4). This gives us 6 x 5 x 4 = 120 different planet types. Therefore, the correct answer is b) 120.

Number of planet types=Number of sizes×Number of atmosphere types×Number of temperature ranges

Given:

Number of sizes = 6

Number of atmosphere types = 5

Number of temperature ranges = 4

Number of planet types

Number of planet types=6×5×4=120

Therefore, the correct answer is:

b) 120
