Answer: Negative 20.75
Step-by-step explanation:
The question simply wants us to convert the temperature shown by the thermometer to decimal. We should note that the temperature shown is Negative 20 and three-fourths degrees.
First, we convert 3/4 to decimal. This will be:
= 3/4 = 0.75.
Therefore, -20 3/4 = -20.75

Answer:
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
Step-by-step explanation:
On the first situation there was a decrease of 25% from the previous value, this mean that the present value is 100 - 25 = 75 % from what it was before. In order to calculate the previous value we can apply a rule of three as follows:
x -> 100%
75,000 -> 75%
x*75 = 75,000*100
x*75 = 7,500,000
x = 7,500,000/75 = 100,000
On the second situation there was an absolute increase of 78 - 65 = 13, this value represents the rate we want to know. In order to find the rate we can apply a rule of three as follows:
65 -> 100 %
13 -> x
1300 = 65*x
65*x = 1300
x = 1300/65 = 20 %
On the first situation the previous salary was $100,000 and on the second one the raise was 20%.
