It is 9 degrees because at 6am the temperature was -12 degrees and at 10am the temperature was -3 degrees.
Answer:
10
Step-by-step explanation:
(-15+45)/3=10
Start by decomposing the number inside the root into primes
Then group the terms into cubes if possible

rewrite the root
![\sqrt[3]{80}=\sqrt[3]{10\cdot2^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B80%7D%3D%5Csqrt%5B3%5D%7B10%5Ccdot2%5E3%7D)
then cancel the terms that are cubes and bring them out of the root
It would be c because when you multiply each number by r you can see the number
The diameter is equal to the radius multiplied by 2.
