For me i just guess lol i dont know the correct answer i just telling you the truth
Step-by-step explanation:
Answer: Line DB
Think of the two planes as pages in a book. They are joined by the spine, which is where the two planes intersect. In this case, that intersection is the line DB.
Point D is on both planes R and S. So is point B. Every point on line DB is found on both planes.
She can read 55 pages per hour
So, divide that by 2 to get 27.5
She can read 27.5 pages in the next 30 Min.
(She would be on page 137.5 :p)
Hope this helps!!
606/100 is equal to 6 6/100= 6 3/50 the answer is b.6 3/50
Answer:
B. (-2, 15)
Step-by-step explanation:
Pretend that your fixed point [2, 9] is at the origin for now by translating it two units <em>west</em><em> </em>then nine units <em>south</em><em> </em>[0, 0]. Now, the same goes for [6, 3]. Translate it two units <em>west</em> then nine units <em>south</em><em> </em>to get [4, -6]. Then, according to the <em>180°-rotation rule</em>, you take the OPPOSITE of both the x-coordinate and y-coordinate:
[4, -6] → [-4, 6]
Now, that you have your rotated point, we have to shift EVERYTHING BACK to the way it was from when we shifted the fixed point of [2, 9] to the origin. We do that by translating everything in reverse order, which is 9 blocks <em>north</em><em> </em>then 2 blocks <em>east</em>:
→ [0, 0] back to [2, 9]
Translation
→ [-4, 6] to the new coordinate of [-2, 15]
