Answer:
Step-by-step explanation:
150 kilometers
60 kph
tank is 20 liters
6 km/l
150/6 = 25 liters needed
$60/l
5 more liters of fuel
total cost 25 x .60 = $15
X is -2,first x plus 10x plus 22 equals 0,so if plus 22 is zero than x minus 10x than plus 22 than you got it,0
Answer: (-3,-6)
Step-by-step explanation:
Answer:
k = 32/ cos 64
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj side / hypotenuse
cos 64 = 32/k
k cos 64 = 32
k = 32/ cos 64
