I think it’s A. Hope it helps
Speed=distance/time
distance = 10,000 m
time= 27 min 30.42s but we need to convert that completely to seconds
(27x60)+30.42= 1650.12 rounded to 1650
speed=10,000/1650.12
speed=6.059063
Because when we do sig dig we round to the least number of digits we would round to 4 because 1650.12 gets rounded to 1650
so 6.059 m/s
Answer:
When a light wave hits a metallic surface, the electrons on the surface are pushed and ... in a process called "total internal reflection", making that surface look shiny too.
Explanation:
metallic shiny nonmetallic dull:)
The circumference of a circle is (pi) x (the diameter).
If the diameter of the wheel is 18 inches (1.5 feet), then its circumference is
(pi) x (1.5 feet) = 1.5π feet .
Every time the wheel rotates once, the car moves 1.5π feet.
1 mile = 5,280 feet
In order for the car to move 5,280 feet, the wheel has to rotate
(5,280 / 1.5π) times.
(5,280 / 1.5π) = 1,120.4508 times
Rounded to the nearest whole number: <em>1,120 revolutions</em>
Answer:
B. symbolic
Explanation:
The mental image formed in Terell's mind is a symbolic mental image.
A symbolic mental image helps to bring perception to imagery formed on the mind.
- This process is symbolic because Terell can see that river ahead.
- If he cannot see the river then it is more of an analogical fantasy.
- The thoughts are predicated on the image of the River seen.
- Therefore, it is right to conclude that this is a symbolic mental image.
