Yes, any set is a subset of itself.
Step-by-step explanation:
N/A
We are given the equation:
h = 22,000 – 480 t
where h is height . The plane will land when h = 0,
therefore:
0 = 22,000 – 480 t
480 t = 22,000
t = 45.83 minutes
<span>hence the plane will land after 45.83 minutes</span>
Answer:
y = 37/36

Answer:
5040
Step-by-step explanation:
24000-5%=1200
1200+5%=1260
1260x4=5040
4b=a then plus 10 to see if the age holds true to 3b=a in ten years. Then since the question is how old is she today? You must either add 6 to young age (of20) or minus 4 from the older (of 30).
So Betty would be 26 today.
