There was a party with 50 students. They had a cylinder root beer keg that was 17 inches in height and 13 inches in diameter. Th

Radda [10]

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

so

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

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

therefore

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

Point T is between the points B and N. If BN = 2x + 50, BT = x +10 and TN = 5x, then what is the value of x?

Firdavs [7]

Answer:

Yes, 1x is the same as x. Technically, the "1" in front of the "x" is called an "implied 1" and, so it's simply written as x. Just simply means that any value multiplied by 1 is always equal to itself.
