Answer:
D)
Step-by-step explanation:
Each longitude has a time difference of 4 minutes.
Convert 4 hours into minutes
4 hours * (60 minutes/1 hour) = 240 minutes
Divide 240 minutes by 4 to obtain the difference in longitude
240/4 = 60
146 area of trapazoid 90
area of triangle 56
For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
Answer: Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
