Answer: the number of miles that Bryan hiked is 160

Step-by-step explanation:

Total distance that Bryan hiked last summer was 8.48x 10^5 feet.

There are approximately 5.3 x 10^3 feet in a mile. Converting 8.48 × 10^5 feet to miles, it becomes

8.48 × 10^5/5.3 x 10^3

Applying the rules of indices which is expressed as

a^x ÷ a^y = a^(x - y)

It becomes

= 1.6 × 10^ (5 - 3)

= 1.6 × 10^2

= 160 miles

The Kuroshio Sea tank is 27m long, 35m wide and 10m deep. What is the volume of the tank? Show your
umka21 [38]

The volume of Kuroshio Sea rank is 9450 cubic meters, if the sea tank is  27m long, 35m wide and 10m deep.

Step-by-step explanation:

The given is,

                 Kuroshio Sea tank is 27m long, 35m wide and 10m deep.

Step:1

                Sea tank looks like a rectangular prism,

                 Formula to calculate the volume of rectangular prism,

                                   Volume, V =whl.............................(1)

                Where, w - Width of the rectangular prism

                              h - Height or depth of the rectangular prism

                               l - Length of the rectangular prism

              From given,

                       w = 35 meters

                         l = 27 meters

                        h = 10 meters

             Equation (1) becomes,

                                              V = (35)(10)(27)

                                                  = (945)(10)

                                                 =9450

      Volume of the sea tank, V = 9450 Cubic meters

Result:

         The volume of Kuroshio Sea rank is 9450 cubic meters, if the sea tank is  27m long, 35m wide and 10m deep.
