1) 46°
Sorry I don’t know the second question
I think it's B and D because both of them will give you the same answer which is 2.71 but turn it into fraction.
Answer:

Step-by-step explanation:

-7.89, -5.23, -5.22, 34.98, 51.02, 51.22
Lets break it down:
(Rational numbers consist of whole, numbers, integers, and fractions)
Negatives come after 0, so the greater the number gets, the less value it has, opposite of positive numbers.
So since -7.89 is the greatest negative number, it will have the least value.
Hope this helps!
Answer:
45.1
Step-by-step explanation:
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
