Answer:

The annual rate of inflation r is $0.013

Step-by-step explanation:

Annual rate of inflation r = (p2p1)1/n-1 = p2p1/n-1

p2 = $5.83, p1 = $0.22, n = 2013 - 1913 = 100

r = $5.83 × $0.22/100 - 1 = $1.2826/99 = $0.013 (to the nearest thousandth)

VikaD [51]

1598 cm square is the area of the container.

According to the statement

we have given that the container is rectangular prism

And Length of rectangular prism is 34cm

Width of rectangular prism is 17 cm

Height of rectangular prism is 20 cm

we use the below written formula to find the surface area

Surface area formula A=(wl+hl+hw)

To find the surface area of the container.

Substitute the values of Length, width and height in the formula then

A=(wl+hl+hw)

A=((17)(34)+(20)(34)+(20)(17))

After solving the values

A=(578+680+340)

A= 1598

So, 1598 cm square is the area of the container.
