Answer:

$\boxed{\text{101 fl oz}}$

Step-by-step explanation:

Step 1. Convert litres to millilitres

$\text{V} = \text{3 L} \times \dfrac{\text{1000 mL}}{\text{1 L}} = \text{3000 mL}$

Step 2.Convert millilitres to fluid ounces

$\text{v} = \text{3000 mL} \times \dfrac{\text{1 fl oz}}{\text{29.6 mL}} = \boxed{\textbf{101 fl oz}}$

Three consecutive odd numbers have a sum of 45. what is the greatest number?

rodikova [14]

Let's assume the middle number is $x$
then the smallest number is $x-2$
the greatest number is $x+2$
so the sum of the three number would be $(x-2)+x+(x+2)$ and it equals 45
now we have an equation $(x-2)+x+(x+2)=45$
then we solve it $3x=45$
$x=15$ , which means the middle number equals 15
so the greatest number would be $x+2=15+2=17$
17 is the greatest number

The volume of the plastic cylinder is 64. A glass cylinder has the same height and radius is half of the plastic cylinder radius

sp2606 [1]

Answer:

I am not sure if I'm correct, but I got 16

Step-by-step explanation:

lets look at the formula for cylinder volume:

V=π*r^(2)*h

now, lets plug in 64

64=π*r^(2)*h

h=64/(π*r^(2))

Volume of glass cylinder is

V=((0.5r)^2)*(64/(π*r^(2)))*π

V=0.25π*r^(2)*(64/(π*r^(2)))

V=16π*r^(2)/(π*r^(2)

V=16
