The situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C
<h3>How to determine the situation?</h3>
The expression is given as:
2 - 5
When the expression illustrates change in temperature, the interpretation can be:
An initial temperature of 2°C decreases by 5°C
Hence, the situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C

Answer:
25 questions.
Step-by-step explanation:
Correct answer = 18
The percent score of the correct answers is 72%.
Let there are x questions in the test. So,
According to the given condition,
![72\%\ of\ x=18\\\\\dfrac{72}{100}x=18\\\\x=\dfrac{18\times 100}{72}\\\\x=25](https://tex.z-dn.net/?f=72%5C%25%5C%20of%5C%20x%3D18%5C%5C%5C%5C%5Cdfrac%7B72%7D%7B100%7Dx%3D18%5C%5C%5C%5Cx%3D%5Cdfrac%7B18%5Ctimes%20100%7D%7B72%7D%5C%5C%5C%5Cx%3D25)
Hence, there were 25 questions in the geometry test.
Answer:
12.686cm
Step-by-step explanation:
By using pythagoras, we can find CB.
We know that ![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Therefore, ![12^2-6^2=CB^2](https://tex.z-dn.net/?f=12%5E2-6%5E2%3DCB%5E2)
(it has to be positive since it is distance)
now we look at triangle BCD and use SOH CAH TOA.
![Sin55=CB/CD\\Therefore, CD= 12.686](https://tex.z-dn.net/?f=Sin55%3DCB%2FCD%5C%5CTherefore%2C%20CD%3D%2012.686)
