Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake
Hope this helps!

1.so what you are going to do it add up all the sides but not just in any order you are going to add up the like terms so 2/3x+1/3x+2/3x+1/3x that adds up to be 2x and the add up 10+5+10+5 which equals 30 so there you go. Your perimeter= 2x+30
2. -2/3 has a repeating decimal
Answer:
t = 10.9
Step-by-step explanation:
9.3-t=-1.6
Subtract 9.3 from each side
9.3-t-9.3=-1.6-9.3
-t =-10.9
Multiply each side by -1 to find t
t = 10.9
