In order to find the number, we will need to set it up in an equation. In total, there are 460 students while 60% of them have pets. Lets set that up.
460(60%)
In order to correctly do this, we will need to transfer 60% into a decimal, which is .6. Now we will rewrite it.
460(.6)
This now can be represented by the number 276.Since we know that 276 is 60% of 460, The total number of students that have pets will be 276.

<u>Answer:</u>
csc = 5/4
<u>Step-by-step explanation:</u>
Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0 with legs x and y and z as its hypotenuse.
Then using Pythagoras Theorem:
Taking square root on both the sides:
Now, 
and we know that 
Therefore, csc = 5/4.
