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.
Step-by-step explanation:
Answer:
a=29/42
Step-by-step explanation:
6a-1÷7=4
first write the division as a fraction
6a-1/7=4
add 1/7 to each side
6a=4+1/7
which is equal to
6a=29/7
divide both sides by 6
a=29/42
Answer:
44 degrees
Step-by-step explanation:
if BAC and DAE are complementary then their sum is equal to 90 degrees
90 - 36 = 44 degrees
Answer:
A
Step-by-step explanation:
the probability should always be the same unless the event is different.
- 2.1 = y/6 + 17.1
- 2.1 - 17.1 = y/6
- 19.2 = y/6
19.2*6 = y
-115.2 = y
So y = - 115.2.
Hope this helps ! This "/" is a fraction.
