Answer:
Step-by-step explanation:
h^2=x^2+y^2, since this is a square x=y=s so
220^2=2s^2
2s^2=48400
s^2=24200
s=24200^(1/2)m (exact)
s=155.56m (rounded to nearest hundredth of a meter)
One hectare is equal to 10000m^2
A=24200m^2(h/10000m^2)
A=2.42 hectares
Answer:
A
Step-by-step explanation:
Answer:
7.5 hours (7 hours and 30 minutes)
Step-by-step explanation:
ok Let's start with 64km/h.
1.6 km=1 mile,
64÷1.6=40miles
so 64km/h changes into 40miles/hour.
Zebras's round trip =300miles,
300/40=7.5
so answer is 7.5 hours.
