I believe this would be an obtuse trapezoid ie a quadrilateral with only 2 sides parallel and in this case with one obtuse angle ie an angle greater than 90 degrees and less than 180 degrees

Answer:

Yes, there will be enough root beer for everyone to have at least one cup

Step-by-step explanation:

step 1

Find the volume of the cylinder root beer keg

The volume is equal to

$V=\pi r^{2} h$

we have

$r=13/2=6.5\ in$ -----> the radius is half the diameter

$h=17\ in$

substitute

$V=\pi (6.5)^{2} (17)$

$V=718.25\pi\ in^{3}$

step 2

Find the volume of the cylinder cups

The volume is equal to

$V=\pi r^{2} h$

we have

$r=3/2=1.5\ in$ -----> the radius is half the diameter

$h=4\frac{3}{4}\ in=4.75\ in$

substitute

$V=\pi (1.5)^{2} (4.75)$

$V=10.6875\pi\ in^{3}$

step 3

Multiply the volume of one cup by 50 (the total number of students) and then compare the result with the volume of the cylinder root beer keg

$10.6875\pi*(50)=534.375\pi\ in^{3}$

$534.375\pi\ in^{3}< 718.25\pi\ in^{3}$

therefore

There will be enough root beer for everyone to have at least one cup

Aleks [24]

Answer:

2x^2=3x+2

2x^2-3x-2=0

(x-2)(x+1/2)=0

x=2 or x=-1/2

The sum of 2 solution 2+-1/2=3/2
