Because the surface area is of a 2-D SHAPE to find a area of a 2-D shape is l x w
Answer:
7 Celsius
Step-by-step explanation:
Initial temperature at 12pm is 1 Celsius.
Rises by 6 (add by 6).
The answer is 19
First you must set up the equation
÷
First, you must make the mixed number a improper fraction
÷
Then you must divide

Finally, simplify
19
F = 15%
v = 5%
0.15f + 0.05v = 0.14*10
15f + 5v = 140
3f + v = 28
f + v = 10 (total volume)
---------- Subtract
2f = 18
f = 9 liters of 15%
v = 1 liter of 5%
1,15 3,5 are the only factor pairs
