Lets use a rule of three simple with direct proportion to solve:
 20 boxes -----> 15 min
100 boxes ----> x
x = (100)(15)/20
x = 75
therefore it takes 75 mins to stack 100 boxes

If we use fractions to solve:
15/20 = x/100
and solve for x.
20/15 = 100/y
solve for y

faust18 [17]

4^{4}, 4^{3},  4², 4^{1}

continuing the sequence, the next three terms will be

4^{0}, 4^{- 1}, 4^{- 2}

the sequence is 256, 64, 16, 4, 1, \frac{1}{4}, \frac{1}{16}

A cylinder has a helght of 16 cm and a radius of 5 cm. A cone has a helght of 12 cm and a radius of 4 cm. If the cone is placed
erma4kov [3.2K]

Answer:

1055.04 cm³

Step-by-step explanation:

Given that,

Height of a cylinder, h = 16 cm

Radius of the cylinder, r = 5 cm

The height of a cone, h' = 12 cm

The radius of a cone, r' = 4 cm

The volume of the cylinder will be :

V=\pi r^2 h\\\\=3.14\times 5^2\times 16\\\\=1256\ cm^3

The volume of a cone is given by :

V'=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times (4)^2\times 12\\\\=200.96\ cm^3

Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³

Hence, the required answer is equal to 1055.04 cm³.
