Diagonal of a cube formula: D=a√3 [a=side length]
D = 5√3 ≈ 8.7 cm.
Answer:
D
Step-by-step explanation:
Answer:
Step-by-step explanation:
The figures are squares, so each side is the same length.
12.2 yd on each side
Area = 12.2² = 148.84 yd²
perimeter = 4×12.2 = 48.8 yd

Convert hours to minutes
----------------------------------------
1 hour 55 mins = 60 + 55 = 115 mins
1 hour 50 mins = 60 + 50 = 110 mins

----------------------------------------
Speed = 36/h
----------------------------------------
1 hour = 36 km
----------------------------------------
Rewrite 1 hour as 60 mins
----------------------------------------
60 mins = 36 km
----------------------------------------
Find 1 min
----------------------------------------
1 min = 36 ÷ 60
1 min = 0.6 km
----------------------------------------
Find 115 mins
----------------------------------------
1 min = 0.6 km
115 min = 0.6 x 115
115 min = 69km

Speed = 72km/h
----------------------------------------
1 hour = 72 km
----------------------------------------
Write 1 hour as 60 mins
----------------------------------------
60 mins = 72 km
----------------------------------------
Find 1 min
----------------------------------------
1 min = 72 ÷ 60
1 min = 1.2 km
----------------------------------------
Find 110 min
----------------------------------------
1 min = 1.2 km
110 min = 1.2 x 110
110 min = 132 km

Total Distance traveled:
----------------------------------------
69km + 132km = 201km
----------------------------------------
Answer: 201 km
----------------------------------------
It is B. Because the 3$ doesn't have any variables and the 2 dollars is per hours so 2x
