I know that 4 is D and 6 is G
Answer:
Y = -4.5x
Step-by-step explanation:
First evaluate: -16x to the second power = -256x
Then add like terms: -256x + 238x = -18x
Then divide both sides by -18: -18x divided by -18/ 81 divided by -18
Which leaves you with y = -4.5x
Answer:3
Step-by-step explanation:
Answer:
The correct conversion is B)
B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s
Hence,
200 km/h ⇒ ![\dfrac{200 \times 1000}{60\times 60}=55.56\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7B200%20%5Ctimes%201000%7D%7B60%5Ctimes%2060%7D%3D55.56%5C%20m%2Fs)
Step-by-step explanation:
Given:
An airplane is traveling at a speed of 200 km/h.
The correct conversion is B)
B) 200km 1hr x 1000m 1km x 1hr 60min x 1min 60s
Reason:
For Converting Speed unit km/h ⇒ m/s
First we need to convert km ⇒ meter
So 1 km = 1000 meter
Secondly, in hour ⇒ seconds first we need to convert it into minutes then to seconds
hour ⇒ minute ⇒ seconds
So 1 hour = 60 minute and 1 minute = 60 seconds
Therefore, 1 hour = 60 min × 60 sec
Hence,
200 km/h ⇒ ![\dfrac{200 \times 1000}{60\times 60}=55.56\ m/s](https://tex.z-dn.net/?f=%5Cdfrac%7B200%20%5Ctimes%201000%7D%7B60%5Ctimes%2060%7D%3D55.56%5C%20m%2Fs)
