You are moving a total from - 13  to + 22. That alone is enough to make someone wonder why they live where they live. (The weather where I live can can do exactly this). 

What is the range of the temperature?
You might think it was -13 to 22. It sounds like it could be 9 degrees. 22 - 13 = 9. 

That is not right. The actual movement is absolute value of (-13) which will be added onto 22.

So the temperature movement is
13 + 22 = 35 degrees.

Hours.
The hours are not as hard to figure out. From 3am to 10 am is 7 hours

Degrees per hour
<em>Formula </em>
Degrees / hour = degrees / hour
degrees = 35 degrees
hour = 7 hours.

Degrees / hour = 35 degrees / 7 hours = 5 degrees / hour.

The average change of temperature per hour is the difference in temperature divided by the difference in hours.

3 a.m.     10 a.m.  ----> difference in time: 10 - 3 = 7
-13           22         ----> difference in temperature: 22 - (-13) = 35

average change of temperature per hour: 35/7 = 5

Answer: 5 degrees per hour

A paint shop stocks 1800 liters of paint 24% of the paint is white. The shops sells 18% of the white paint and 7% of the rest of
Anuta_ua [19.1K]

Answer:The amount of paint that was sold altogether is 173.36 litres

Step-by-step explanation:

The total amount of paint that the paint shop stocks is 1800 litres.

24% of the paint is white. It means that the amount of white paint would be

24/100 × 1800 = 0.24 × 1800 = 432 litres.

The amount of the remaining paint other than white would be

1800 - 432 = 1368 litres

The shops sells 18% of the white paint. This means that the amount of white paint sold by the shop will be

18/100 × 432 = 0.18 × 432 = 77.6 litres.

The shops sells 7% of the rest of the paint.

This means that the amount of the rest paint sold by the shop will be

7/100 × 1368 = 0.07 × 1368 = 95.76 litres.

The amount of paint that was sold altogether would be

77.6 + 95.76 = 173.36 litres
