Answer:

x = 40 1/2

Step-by-step explanation:

The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.

x = 81/2

x = 40 1/2

___

You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.

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

Kipish [7]

4/7 = y/5019....with y being yes votes
cross multiply
(7)(y) = (4)(5019)
7y = 20076
y = 20076/7
y = 2868 <=== yes votes

total of yes and no votes : 5019 + 2868 = 7887
