Step-by-step explanation:
Find the value in Australian dollars for each exchange rate.
<span>1st exchange rate: </span>
<span>14000/6.21= $2254.43 </span>
<span>2nd exchange rate: </span>
<span>14000/6.37= $2197.80 </span>
<span>Find the difference between the two: </span>
<span>$2254.43 - $2197.80 = $56.63 </span>
Since the first value is greater than your second one Aggie lost money and your answer is <span>It decreases by $56.63.</span>
Answer:

Step-by-step explanation:
<-- Given
<-- Distributive Property
<-- Find LCD of x-terms
<-- Combine Like Terms

<-- Subtract 7 on both sides
<-- Divide both sides by 289/60
Answer:
Step-by-step explanation:Wait im confused.
v₀ = initial velocity of the freight train while it approach a road crossing = 16 km/h = 16 (5/18) m/s = 4.44 m/s
v = final velocity of the freight train after it crosses a road crossing = 65 km/h = 65 x 5/18 m/s = 18.06 m/s
t = time to do so = 10 min = 10 x 60 sec = 600 sec
acceleration is given as
a = (v - v₀ )/t
a = (18.06 - 4.44)/(600)
a = 0.023 m/s²
a = 294
