To answer the problem above, we first find the velocity of the train that is travelling. It is calculated as follows:
Velocity = 42 km / 15 min = 2.8 km / min
The distance traveled after 3 hours at this speed is calculated by multiplying the velocity and the number of hours.
Distance = <span>2.8 km / min ( 3 hours ) ( 60 min / 1 hour ) = 504 km</span>
Answer: 51.75
Step-by-step explanation: 15 precent of 45 is 6.75
Then add 45+6.75
Easy
leading coefiencet means highest power coefient
degree is the power of the highest exponent
5th degree and leading coefienct is 4
means highest exponet is 5 and the coefienct is 4
means any thing with 4x^5 such that there is no x^n where n>5
4x5 + 3x + 1 is the answer (2nd one)
X = 180 - (67 + 52)
because all 3 of them angles form a line....meaning all 3 angles, when added = 180
Check the picture below.
notice, we have three pair of sides, let's add them all up to get the area
