6.8/5 = 1.36
1.36 x 8 = 10.88
This means that the cost of an adult is $10.88
Both of the Students are correct, where the units are the same in the beginning and at the end. If you divide 20 feet by 4, you get 5 feet or 60 inches. If you convert 20 feet to inches, you get 240 inches. When you divide 240 by 4, you get 60 inches. Therefore, they both are correct.

Answer:
(c) $72
Step-by-step explanation:
Each tile is 8/12 ft = 2/3 ft on a side. Then 8/(2/3) = 12 tiles will fit along each edge of the square area to be tiled. That is ...
12 × 12 = 144
tiles will be needed to cover the area.
The cost of 144 tiles at $0.50 each is ...
(144)($0.50) = $72.00
By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
<u>Step-by-step explanation:</u>
We need to find How many different ways can a researcher select 4 rats from 15 rats and assign each to a different test.Let's find out:
We will use Permutation here : As we will chose 4 rats out of 15 rats , order will be considered which will make this as a permutation problem . Formula for permutation is given by :
⇒ 
According to question , we have
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , By 32,760 different ways can a researcher select 4 rats from 15 rats and assign each to a different test .
