Let x be the jug, 
for half-filled, y for the weight of the jug when empty.
∵ x + y = 2.6 kg
∵ x = 4 kg
∴ ⋅ 4 + y = 2.6 kg
∴ 2 + y =2.6 kg
∵ y = 2.6 - 2 = 0.6 kg
∴ The weight of the empty jug = 0.6 kg
2 hours 20 minutes is the same has 2.33 (two and a third hours) which is the same as 7/3 hours. So if he is traveling at 6km/hour and travels 7/3 hours the answers is 6x7/3=14km
Answer:
Step-by-step explanation:
Use the exponential function
where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.
I believe the answer is B: 13.2 because to find the area of a triangle you do l x w x 1/2.
8 x 3.3 x 1/2 = 13.2.
Answer:
17/9 or 1 8/9 if you are looking for a mixed fraction
Step-by-step explanation:
1 7/9 + 4/36
16/9 + 4/36
Multiply 16/9 by 4/4 to get the same denominator as 4/36
64/36 + 4/36
68/36 = 17/9 = 1 8/9
