tadah!
Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:
1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:
Using this value of x in first equation, we get:
Thus the cost of one hot dog is $1.20
I think it's either A or D. but I'm leaning towards A so try that one

Step-by-step explanation:
First of all, the definition of siphoned according to the online dictionary is:
<span>"a tube </span>used to<span> convey liquid upwards from a reservoir </span>and then <span>down to a lower level of its </span>own <span>accord. Once the liquid </span>has been <span>forced into the tube, </span>typically<span> by suction or immersion, </span>flow continues unaided<span>.'
LOL, the definition doesn't make any difference. Let's actually solve the questions now.
First, find the volume of the water drum which is 5x4x2= 40m^2. (remeber it is "completely full of water")
</span>
Second, divided it by (1.5)^2 x(pi). Essentially you are dividing the volume of water by the surface area of one side of a cylinder. (note: I square 1.5 since you use the radius not the diameter for the calculation)
