Answer:
Step-by-step explanation:
123 X 8000 = 984000
984000/48 = 20500(PUT EURO SIGN)
BC and BCE are Before Common Era
So what you want to do is add 1952 and 384
1952 + 384 = 2336
So the amount of years between 384 BC and 1952 AD is about 2,336 years
Hope this helps
Answer:
3.5 hours
Step-by-step explanation:
Speed of train X=30 mph
Speed of train Y=40 mph
Relative speed When the two trains travelling in same direction
Relative speed=40-30=10 mph
Total distance =25+10=35 miles
We have to find the time when train Y is 10 miles ahead of train X.
We know that
Time=![\frac{Distance}{Relative\;speed}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7BRelative%5C%3Bspeed%7D)
Using the formula
Then, we get
Time=![\frac{35}{10}=3.5 hours](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B10%7D%3D3.5%20hours)
Hence, it will be 3.5 hours until train Y is 10 miles ahead of train X.
Answer:
![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
Step-by-step explanation:
Given
sinΘ =
= ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
Then the hypotenuse = 5 and one leg of the right triangle is 3
Using Pythagoras' identity to find the second leg (x)
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ⇒ x = 4
cosΘ =
= ![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
