The formula for surface area is SA = 2 (wl + hl + hw). Plugging in the numbers that we know, we get SA = 2 (100 + 10h +10h). We know that the crust accounts for half of the surface area.
The surface area was not provided so this is the closest I can go without the provided surface area. I hope this helps you :)

Answer:
350 km/h
Step-by-step explanation:
Speed = distance/time
speed = (700 km)/(2 h) = 350 km/h
Answer:
2
Step-by-step explanation:
=6/3
=2
<span>1st train DATA:
rate = 50 mph ; time = x hrs ; distance = rt = 50x miles
2nd train DATA:
rate = 55 mph ; time = (x-(1/2)) hrs ; distance = rt = 55(x-(1/2)) miles
Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)
Hope this helps!</span>
Answer:
The price elasticity of demand is 0
Step-by-step explanation:
The demand function for monthly sales is given as:
q = 104e^-3p^2 + p
The price elasticity of demand E is obtained by differentiating q with respect to p
E = dq/dp = (-6p + 1) × 104e^-3p^2 +p =
When p = ¥200
E = (-6×200 + 1) × 104e^-3(200)^2 + 200 = -1199 × 104(0) = -1199 × 0 = 0
