julia-pushkina [17]

Answer: student tickets = 208

Adult tickets = 97

Step-by-step explanation:

x + y = 305

x = 305 - y

5x + y = 693

A right rectangular prism has a length of 6 cm a width of 8 cm and a height of 4 cm the dimension of the prism are half what is
Setler [38]

Answer:

Answer 24 cm^3

Step-by-step explanation:

If the dimensions are 1/2  the volume is 1/8 the original volume. There are 2 ways to do this. I'm going to choose the most straight forward.

Formula

V = L * w * h

Givens

L = 6

w = 8

h = 4

Solution

V_original = 6 * 8 * 4 = 192

V_half = 3 * 4 * 2 = 24

V_original / V_half = 192/24 = 8/1

So the other way around (V_half/V_original) = 1/8
