Step-by-step explanation:
18-4^2=2
<span>Given that the orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P = a^(3/2).
If Saturn’s orbital period is 29.5 years, then
29.5 = a^(3/2)
a = (29.5)^(2/3) = 9.547
Therefore, Saturn's distance from the sun is 9.547 astronomical units.</span>
Answer:
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
Hello,
Let's assume x the time the express runs.
56*x=35*(1.5+x)
==>21x=52.5
==>x=2.5 h =2 h 30 min
Let that number be 'x'
So the inequality will be
- 18 + x > 22
or x - 18 > 22
Hope This Helps You!
