The equivalent pair of the given expression is; [4.8] and [3.21]
<h3>How to find equivalent pairs?</h3>
Floor function states that the greatest integer that is less than or equal to x. It is represented by: ⌊ x ⌋.
Ceiling function states that the least integer that is greater than or equal to x. It is represented by ⌈ x ⌉.
Kareem wrote the expressions;
[3.2] [2.7] [2.9] [4.8]
By definition above;
[3.2] = 4
[2.7] = 2
[2.9] = 3
[4.8] = 4
Thus, the equivalent pair is [4.8] and [3.2]

Answer:
It's F
Step-by-step explanation:
You can see on the graph that 2 lines cross at (-3;4) so this is the point where the 2 equations have the same outcome/ value.
The expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Solution:
Given expressions are 15t – 2t and 2t – 15t.
To determine 15t – 2t is equivalent to 2t – 15t or not.
Substitute t = 2 in above two expressions.
15t – 2t = 15(2) – 2(2)
= 30 – 4
= 26
2t – 15t = 2(2) – 15(2)
= 4 – 30
= –26
The values of the expressions are different when t = 2.
So, 15t – 2t is not equivalent to 2t – 15t.
Hence the expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Is it 0.092?
I got this by using the information from pH 4 which is 15 and doubling it to make 30 and taking away 5 (we get 5 from halving the the rate for reaction at pH6) to get 25.
0.071 x 2= 0.142
0.100/2 =0.05
0.142+0.05 =0.092
