If Joe and Eugene are travelling in opposite directions, their total distance is 360 km.
Eugene's speed = 70 km/hour
Let Joe's speed be = x
They each travel for 3 hours, so time = 3 hours
Distance = speed * time
Hence, Joe's speed is 50 km per hour.
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
Answer:
6^2
Step-by-step explanation:
When they are divided, just subtract the exponents. 5 - 3 = 2
0.09 = 0.00 because 0 in the tenths is nearer to the 0 than the next number or digit :)
