Answer:
13.8 miles
Step-by-step explanation:
The driving distance from Alex's house to the museum is 
miles
Since the distance from his house to the museum does not change, his trip back is also miles.
The Round-Trip Distance is the distance to and from the museum.
To determine this, there ate two approaches.
- Add the distances together
- Multiply the distance to by 2.
Approach 1
Approach 2
The round trip distance is 13.8 miles.
C=£9+50f
Please let me know if it’s correct also please mark brainliest please.

Answer:
0.9043secs and 0.3456secs
Step-by-step explanation:
Given the height of an overhand volleyball modeled as h=-16t^2+20t+6.
If the height is 11feet, then;
11 = -16t^2+20t+6.
-16t^2+20t+6 - 11 = 0
-16t^2+20t-5 = 0
Multiply thriugh by -1
16t^2-20t+5 = 0
Factorize
t = 20±√20²-4(16)(5)/2(16)
t = 20 ±√400-320/32
t = 20 ±√80/32
t = 20 ±4√5/32
t = 20±8.94/32
t = 28.94/32 and 11.06/32
t = 0.9043 and 0.3456
Hence the required time are 0.9043secs and 0.3456secs
