Find the surface area of the rectangular prism. A drawing of a rectangular prism with length 6 miles, width a mixed fraction of two and one third miles and height a mixed fraction of one and one fourth miles.

48.83

Step-by-step explanation:

Formula of surface area is 2(wl+hl+hw)

Plug your numbers into the formula.

2[(2.333*6) + (1.25*6) + (1.25*2.333) = 48.83

Hope this helps!

(I converted the fractions into decimals)

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
