Answer:
look below but sorry that i dont know part b
Step-by-step explanation:
y = 5/2x-3
slope=5/2 y-int = -3
y=x-9
slope=1/1 y-int=-9
y=5x
slope= 5/1 y int=0
y=-1/2x +5
slope=-1/2 y-int= 5
plzzzz plzplz mark me brainliest thank you!!!!!!!!!!!!
Answer: 20 hours
Step-by-step explanation: We want to round our answer to the nearest hour, we know that the rocket can travel 200 miles per 1 minute, but we want to know first how many miles the rocket can travel per 60 minutes or 1 hour.
To find how many miles the rocket can travel at 60 minutes or 1 hour, simply multiply 200 x 60. 200 x 60 = 12,000 miles per hour.
Now, we want to find how many hours it would take for the rocket to travel from the earth to the moon.
Simply divide 239,000 by 12,000 to get the amount of hours it would take to reach the moon. 239,000/12,000 = about 20 hours.
So, it would take the rocket ship 20 hours to reach the moon from the earth.

Answer:
x = 14.4
Step-by-step explanation:
x is sin(angle 24/30)×24
how do we get the angle at 24/30 ?
by using the extended Pythagoras for baselines opposite other than 90 degrees.
c² = a² + b² - 2ab×cos(angle opposite of c)
in our example the angle 24/30 is opposite of the side 18.
so,
18² = 24² + 30² - 2×24×30×cos(angle 24/30)
324 = 576 + 900 - 1440×cos(angle 24/30)
324 = 1476 - 1440×cos(angle 24/30)
1440×cos(angle 24/30) = 1152
cos(angle 24/30) = 1152/1440 = 576/720 = 288/360 = 144/180 = 72/90 = 36/45 = 12/15 = 4/5
angle 24/30 = 36.9 degrees
x = sin(36.9) × 24 = 14.4
