Mr. Chiro drew a design for an outdoor kitchen. The food prep area will be on a rectangular platform made of concrete that is 5 feet high. The storage shelf will be on a similar platform that is 6 feet high. What will be the total volume of the platforms?

The volume of platform

= 11 ft³

Step-by-step explanation:

The height of the Platforms are

The food prep area  = 5 ft

Storage shelf = 6 ft

Side of rectangle = b width of platform = d

Therefore area of platform = b·d

Volume of the food prep area platform = Area × height = 5 b·d ft³

Volume of the storage shelf  platform = Area × height of storage shelf platform = 6 b·d ft³

Therefore the total volume = Volume of food storage platform + volume of storage shelf platform = 5 b·d ft³ + 6·b·d ft³ = 11·b·d ft³

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
