Answer:
4 tens, 3 twenties
Step-by-step explanation:
4 tens ($40) and 3 ($60) twenties work. I’m sorry I don’t have a formula for it though.
Answer:
-4 < x ≤ -3
Step-by-step explanation:
Separate it into 2 inequalities
2x+6 ≤x+3
x ≤-3
x+3<3x+11
-8 < 2x
x > - 4
Combine the 2 results
-4 < x ≤ -3
Answer:
a for saturn is 9.55 astronomical units
Step-by-step explanation:
Here, we are interested in calculating the distance from the sun.
Mathematically, from the question;
P = a^3/2
29.5 = a^3/2
a = 29.5^2/3
a = [3√(29.5)]^2
a = 9.55 in astronomical units
