Answer:
B. 36+12sqrt(2)
Step-by-step explanation:
We can use Pitagoras' theorem to find the height of the triangle
15^2=9^2 + h^2
h^2=144
Lets apply square root to the whole equation:
sqrt(h^2=144)
h=12
With the height, we can now find the length of AC.
Sin(45)=12/AC.
AC=12/Sin(45)=24/sqrt(2)=12*sqrt(2) if we rationalize.
Now, lets fin the missing segment between B and C (call it)
where 9+x= BC
Cos(45)=x/AC
x=cos(45)*AC=12
Now, the perimeter is the sum of all its sides
AB+AC+BC=15+12*sqrt(2)+9+12=36+12sqrt(2)
Answer:
(I might not be correct)
Step-by-step explanation:
I think she wants you to talk about how they got seperated to either death camps or working camps. Back then if you could not work or if you were a woman you would be sent off to "death camps". Men who could work ( were strong enough. Some men where not) were sent to work camps. Also if you were too old to work you would be sent of into death camps. So in conclusion, your teacher wanted you to talk about how the jews were sepearted into eaither working camps or death camp
Answer:
9
Step-by-step explanation:
Answer:
20 * 10⁻⁹
Explanation:
Assume that the number of times is t
Now, we want to know what number (t) multiplied by 2 * 10¹⁴ will result in
4 * 10⁶
Translating this into an equation:
2 * 10¹⁴ * t = 4 * 10⁶
Solving for t:
t = (4 * 10⁶) / (2 * 10¹⁴)
t = 20 * 10⁻⁹
Hope this helps :)
The answer will be 60+ because 48 minutes is a long time and if youstudy for a long time you memorize more
