no entiendo porque esta en ingles yes
Answer:
Step-by-step explanation:
8.
center=(3,3)
9. endpoints of a diameter=(0,3) and (6,3)
10.a point of tangency=(6,3)
11. (0,3) and (3,0)
12. endpoints of radius=(3,3) and (6,3)
Let x be the number of seventh grade students.
The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.
The 16 2/23% of those students also have science class in the morning means:
16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning
30 students have math in the morning but not science in the morning
83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180
There are 180 seventh graders.
It’s a little surprising that this question didn’t come up earlier. Unfortunately, there’s no intuitive way to understand why “the energy of the rest mass of an object is equal to the rest mass times the speed of light squared” (E=MC2). A complete derivation/proof includes a fair chunk of math (in the second half of this post), a decent understanding of relativity, and (most important) experimental verification.
