Answer:
Final temperature of the solution is 14°C.
Step-by-step explanation:
Given that,
Initial temperature of the solution, ![T_i=31^{\circ}\ C](https://tex.z-dn.net/?f=T_i%3D31%5E%7B%5Ccirc%7D%5C%20C)
The change in temperature of the solution, ![\Delta T=-17^{\circ}\ C](https://tex.z-dn.net/?f=%5CDelta%20T%3D-17%5E%7B%5Ccirc%7D%5C%20C)
We need to find the final temperature of the solution.
Change in temperature = Final temperature - initial temperature
![\Delta T=T_f-T_i\\\\T_f=\Delta T+T_i\\\\T_f=-17+31\\\\T_f=14^{\circ} C](https://tex.z-dn.net/?f=%5CDelta%20T%3DT_f-T_i%5C%5C%5C%5CT_f%3D%5CDelta%20T%2BT_i%5C%5C%5C%5CT_f%3D-17%2B31%5C%5C%5C%5CT_f%3D14%5E%7B%5Ccirc%7D%20C)
So, the final temperature of the solution is 14°C.
Answer: 120, 60, 180
Step-by-step explanation:
1) Area of a rectangle's formula is:
l × w
So, looking at the diagram, we get:
6 × 20 = 120 cm²
2) Area of a trapezoid's formula is:
× h (where both a and b are the different base lengths)
So, looking at the diagram, we get:
× 4 = 60 cm²
3) Add both to find the area of the entire figure.
120 + 60 = 180 cm²
Answer:
c = 6.32
Step-by-step explanation:
![{a}^{2} + {b}^{2} = {c}^{2} \\ {2}^{2} + {6}^{2} = {c}^{2} \\ 4 + 36 = {c}^{2} \\ 40 = {c}^{2} \\ c = \sqrt{40} \\ c = 6.32](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%2B%20%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20%20%5C%5C%20%20%7B2%7D%5E%7B2%7D%20%20%2B%20%20%7B6%7D%5E%7B2%7D%20%20%3D%20%7Bc%7D%5E%7B2%7D%20%20%5C%5C%204%20%2B%2036%20%3D%20%20%7Bc%7D%5E%7B2%7D%20%20%5C%5C%2040%20%3D%20%20%20%7Bc%7D%5E%7B2%7D%20%20%5C%5C%20c%20%3D%20%20%5Csqrt%7B40%7D%20%20%5C%5C%20c%20%3D%206.32)
