Answer:

b = 6 units

Step-by-step explanation:

Area = 1/2bh

8 = 1/2(b)(8/3)

divide both sides by 1/2

16 = b(8/3)

multiply both sides by 3

48 = 8b

divide both sides by 8

b = 6 units

For your boxes:

1/2 x b/1 x 8/3 = 8/1

b/1 x 8/3 = 16/1

8b/3 / 8 = 2/1

b/3 x 3 = 6

Mrs. Hartka is packaging soup in cylindrical cans. She calculated the volume of soup to be 325 cubic centimeters per can. The ar
GarryVolchara [31]

The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.

Step-by-step explanation:

The given is,

                  The volume of soup to be 325 cubic centimeters per can.

                  The area of the base of each can is 25 square centimeters.

Step: 1

                 Formula to calculate the volume of cylidrical soup can,

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

               Where, B - Base area of cylidrical soup can

                            h - Height of cylindrical soup can

Step: 2

            From the given values,

            Base area, B = 25 square centimeters

                Volume, V = 325 cubic centimeters

            Equation (1) becomes,

                          325 = ( 25 ) (h)

                               h = \frac{325}{25}

                                  = 13 centimeters

           Height of cylindrical soup can, h = 13 centimeters

Result:

            The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.

From his home, Dan would have to walk due north to get to his friend Samuel's house and due east to get to his friend Cindy's ho
maksim [4K]

The distance from Dan's house to Samuel's house is 4 km

The distance from Dan to Samuel house, Dan to Cindy house and Samuel to Cindy house forms a right angled triangle.

Distance from Dan to Samuel house = x, Distance from Dan to Cindy house = 3 km and Distance from Cindy to Samuel house = 5 km

Pythagoras theorem shows the relationship between the lengths of a right angled triangle.

Using Pythagoras theorem:

5² = x² + 3²

25 = x² + 9

x² = 16

x = 4 km

Hence the distance from Dans house to Samuel's house is 4 km
