I think the answer is “C” too. See if this pic could help you understand.
The number -57/ 7 is a rational number.
<h3>What are rational numbers?</h3>
A rational number is a type of real number, in the form of;
p/q
where
- q is not equal to zero
- p is a whole number.
It is important to note that any fraction with a denominators not equal to zero is a rational number
Examples of rational numbers are 1/2, 1/5, 3/4, and so on.
Also, the number “0” is also a rational number, but when it is represented forms such as 0/1, 0/2, 0/3, etc. But, 1/0, 2/0, 3/0, etc. It is not rational
- 57/ 7 is a rational number
Thus, the number -57/ 7 is a rational number.

I think the 3 is an exponent so we can write the expression as
18 * 4y^3
= 72y^3
The advance tickets were 35 in number and the same day ticket will be 30 in number.
<h3>What will be the number of tickets?</h3>
To find out the number of the tickets sold we will give some notations so the notations are as follows:-
A= Cost of advance tickets=$30
S= cost of same-day ticket-=15
Number of the advance tickets
Number of same-day tickets.
The equations made by the given data will be:-
By solving the above equations:-
Hence the advance tickets were 35 in number and the same day ticket will be 30 in number.

Answer:
Step-by-step explanation:
Since the triangle has a right angle, we are going to use pythaogoran theoem, which is , where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
9+36=c^2
45=c^2
=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
Then take the sqr root of 9 and we have
