Answer:
Speed = 24 km/h
Step-by-step explanation:
Speed = Distance / Time
A cyclist travels 12 km from home to the park.
She leaves home at 13:00 and arrives at the park at 13:30.
Distance = 12 km
Time = 0.5 Hours
Speed = 12 / 0.5
Speed = 24 km/h
Answer:
w = 36
Step-by-step explanation:
You can make a ratio 98 : 84 = 42 : w
![\frac{49}{42}=\frac{42}{w}](https://tex.z-dn.net/?f=%5Cfrac%7B49%7D%7B42%7D%3D%5Cfrac%7B42%7D%7Bw%7D)
49w = 1764
w = 36

Step-by-step explanation:
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Number of hours of pop music = 3
Number of hours of classical music = 2
According to question, Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change.
Rate of increment = 5% = 0.05
Let the number of months be 'x'.
So, our required function becomes,
![f(x)=3(1+0.05)x+2\\\\f(x)=3(1.05)x+2](https://tex.z-dn.net/?f=f%28x%29%3D3%281%2B0.05%29x%2B2%5C%5C%5C%5Cf%28x%29%3D3%281.05%29x%2B2)
Hence, Option 'd' is correct.
