just olya [345]
Because, actually, I'll give an example. 4/5 + 3/4, the LCM of the denominators is 20, so you would get this to be 16/20 + 15/20, which would equal 31/20, which equals 1 11/20.

What is the value of z?
weqwewe [10]

Answer:

z = 30.45 feet

Step-by-step explanation:

The volume (V) of a triangular prism is calculated as

V = area of triangular end (A) × length

Here V = 913.5 and length = 15, thus

A × 15 = 913.5 ( divide both sides by 15 )

A = 60.9 ft²

The area of the triangle = \frac{1}{2} bh ( b is the base and h the height ), thus

\frac{1}{2} × 4 × z = 60.9

2z = 60.9 ( divide both sides by 2 )

z = 30.45
