Answer:
16.67% of cases of tapes were sold.
Step-by-step explanation:
We are given the following in the question:
Number of cases of tapes sold = 24
Thus is 20% of tapes left.
Let x be the total number of tapes left.
Thus, we can write:

Thus, total number of tapes =

Percentage of tapes sold =

Thus, 16.67% of cases of tapes were sold.
The statements that are true are
- This graph is a function because the value of x is the same for every value of y
- The equation of this line is x = 3. Options B and D
This is further explained below.
<h3>What are the
statements?</h3>
Generally, A relation is considered to be a function if it can be shown that each value from the set of first components of ordered pairs is connected with precisely one value from the set of second components of ordered pairs.
In conclusion, You may also consider this in terms of the fact that there is one and only one y associated with each x.
Although it is obvious that this is not the case, the calculation for the vertical line nevertheless uses these terms.

Answer:
Step-by-step explanation:
Let the number of cockles be c and that of winkles be w.
From the first relation,
w = 2c ..........(I)
From the second relation, 6 winkles are accidentally split.
This in equation form means the following:
c/w- 6 = 3/5
By cross multiplication,
5c = 3(w - 6)...........(ii)
We know w = 2c , let’s substitute this into the second equation.
5c = 3(2c - 6)
5c = 6c - 18
Collecting like times, c = 18
And w = 2c = 2(18) = 36
Hence, there were initially 18 cockles and 36 winkles
The suquare root is 10. it is a rational number
Sin(12) ≈ 0.208
cos(x) = 0.208
cos(x) = sin(12)
cos(78) = sin(12)
cos(12) ≈ 0.978
cos(68) ≈ 0.375
cos(102) ≈ -0.208
cos(78) ≈ 0.208
The answer is D.
