Three blocks are shown: block a has mass 3 kilograms, length 8 centimeters, height 2 centimeters, and width 1 centimeters. block b has mass 4 kilograms, length 1 centimeters, height 8 centimeters, and width 2 centimeters. block c has mass 4 kilograms, length 8 centimeters, height 1 centimeters, and width 2 centimeters. which statement is correct?

B and C

Explanation:

We assume that the blocks are of the same material. Therefore, the mass and volume of each block is related. To see which relationship is correct let's find the volume of the blocks

Block A

     V = l * h * w

     Vₐ = 8 * 2 * 1 = 16 cm²

     mₐ = 3 Kg

B block

     Vᵇ = 1 * 8 * 2 = 16 cm²

     mᵇ = 4 Kg

Block C

     Vc = 8 * 1 * 2 = 16 cm²

     m c = 4 Kg

We can appreciate that all the blocks have the same volume

As we can see the expressions B and C are equivalent, so they are true, since for block A with the same volume indicates a smaller mass

truck y has a greater velocity than truck x.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
