Answer:
Step-by-step explanation:
I realize that the time is passed.... but FYI
BD is <u><em>Geometric Mean</em></u>
That's mean BD² = 6 × 5 = 30 ⇒ BD = √30
x² = BD² + 6² = 30 + 36 = 66 ⇒ x = √66
y = √55
Quick answer Sin(570) = - 1/2
Comment
570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.
Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.
What is 570° (∅) degrees equivalent to?
We keep on subtracting 360 until we get a number between 0 and 360 inclusive.
Written this way 0 ≤∅≤360
570 - 360 = 210°
So we need to find the equivalent of 210°
Method
210° = 180° + 30°
This means that ∅ is 30° below the x axis in the 3rd quadrant.
Sin(30) = 1/2
In the third quadrant, the sine is minus. so
sin(210°) = - 1/2 <<<<<<< Answer

Answer:
(x -t -250)/2
Step-by-step explanation:
The amount left from x after paying t and 250 is ...
x -t -250
If this is split into two equal parts, each share is ...
share = (x -t -250)/2
Hmmm...
We have to divide 12 by 8, since we need to see how 8 students will share 12 slices.
12/8=1 and 1/2
So, each student can have a slice and a half, but since we aren't allowed to cut the slices...
We can let each student have one slice, with 4 left over, so...
Every student can have one slice, and then half can have a second slice :)!
I'm not sure if that is what was meant by the question, but that was all I could think of.
I hope I helped! :)
If I understand this correctly you can write it as
22
twenty-two, or
20+2
I hope this helps!!! Please mark brainliest if correct!!!
