Answer:

A


Step-by-step explanation:

  • During 2008-2009 session, 20% of students were in A-B Honor Roll.
  • During 2009-2010, 200 out of 1000 students were in A-B Honor Roll. What's that in percentage? We divide 200 by 1000 and then multiply by 100:

\frac{200}{1000}=0.2*100=20

So, that's also 20%. That's the same as 2008-2009 session, so the principal is wronged!


Option A is correct: "<em><u>A) There was no change in the number of students on honor roll from one year to the next."</u></em>

A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

Please help me find the greatest common factor for these 2 problems..
Kisachek [45]

A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.

11. The prime factorization of 12 is 3 * 2 * 2. The prime factorization of 18 is 3 * 3 * 2. Looking at the prime factorizations, we can see that both of them have 3 and 2. That means that the GCF is 3 * 2 which is 6.

12. The prime factorization of 48 is 2 * 2 * 2 * 2 * 3. The prime factorization of 80 is 2 * 2 * 2 * 2 * 5. We see that the numbers shared are 2, 2, 2, and 2. That means that the GCF is 2 * 2 * 2 * 2 or 16.

p=51*100/75=5100/75=68 $

68$ - 51$=17 $
