The volume of the triangular block is 4 cubic inches. What is the approximate length of y? Round to the nearest 10th of an inch.

2.8 in

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular end and h is the length )

A = × x × x = x² , thus

V = x² × x = 4 , that is

x³ = 4 ( multiply both sides by 2 )

x³ = 8 ( take the cube root of both sides )

x = = 2

Using Pythagoras' identity on the right triangle with hypotenuse y, then

y² = x² + x² = 2² + 2² = 4 + 4 = 8 ( take the square root of both sides )

y = ≈ 2.8 in ( to the nearest tenth )

answer: haha (: i’ll go see what it is

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
