Answer:
Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.
Step-by-step explanation:
Since the Gotemba walking trail up Mount Fuji is about 9km long, and walkers need to return from the 18km walk by 8pm, if Toshi estimates that he can walk up the mountain at 1.5km / h on average, and down at twice that speed , these speeds taking into account meal breaks and rest times, to determine what is the latest time he can begin his walk so that he can return by 8pm the following calculation must be performed:
Climb: 1.5 km / h
Descent: 2 x 1.5 km / h = 3 km / h
Climb: 9 km / 1.5 km / h = 6 hours
Descent: 9km / 3 km / h = 3 hours
Total: 9 hours
8 PM = 20:00
20:00 - 09:00 = 11:00
Thus, Toshi must begin his walk at 11:00 AM in order that he can return by 8:00 PM.

Answer:
? = √87 ≈ 9.33
Step-by-step explanation:
The square of the hypotenuse (h) of the small triangle is the sum of the squares of its legs.
h^2 = 5^2 + 12^2 = 25 +144 = 169
The square of the hypotenuse of the large triangle is also the sum of the squares of its legs.
h^2 +?^2 = 16^2
169 +?^2 = 256
?^2 = 256 -169 = 87
Taking the square root, we find the missing leg length to be ...
? = √87 ≈ 9.33
What is the missing number in 73, 67, 61,____, 49, _____, 37 A.55,42 b.55,43 c. 55, 32 D. 55, 34
xeze [42]
Answer:
b) 55 and 43
Step-by-step explanation:
I can tell by the first 3 or so numbers that the sequence is decreasing by 6 each time, so when you go from 61- blank - 49 it has to be 55 and same with the other one.
