Answer:

V =718.0866 in^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

The radius is 3.3 and the height is 21

V = pi (3.3)^2 * 21

V = pi (10.89) (21)

V =pi 228.69

We can approximate pi by 3.14

V = 3.14(228.69)

V =718.0866 in^3

5 and 1/4 can be 5.25 so all you have to do is divide that by 3 and you’ll get 1.75 per container.

If you wanted to keep it as a fraction, 5 and 1/4 would become 21/4 (you do 5 x 4= 20 + 1) and for fractions I always remembered dividing as ‘Keep, Change, Flip’ so you would do 21/4 for keep. Change would be to change the sign from division to multiplication. And for Flip you would flip 3 over 1 (3/1) to 1/3

Putting that all together would be 21/4 x 1/3 which also equals 21/12 by multiplying the denominators and numerators. Then you simplify, dividing it by 3 to equal 7/4 and another simplify to be 1 and 3/4 which is 1.75.


Hope this helps!

SOMEONE PLEASE HELP ME WITH THIS.
Softa [21]

If the function is defined for all x \neq m, it means that m is a point who doesn't belong to the domain of the function.

Now, since your function is a ratio, you can't have zero denominator. So, if a point nullifies the denominator, it can't belong to the function domain.

In your case, the denominator is x-2, which is zero when

x-2=0\iff x=2

So, this function can't be evaluated at x=2, and in other words, the function is defined when x \neq 2, so that's the value for m.
