The answer is 640 because if you multiply the total student of 6h grade by 100 and divide by 30. You will get the total of student in the school

I believe the answer is 640 students. To get this answer you need to divide 192 by 30% in decimal form so it would look like 192/0.30 and that should get you 640 students!!!

Jim is two years older than his sister Mary. The sum of their ages is greater than 32. Describe Mary’s age. Create and inequalit
-Dominant- [34]

Let the two ages be j and m, respectively.  Then j+m>32.

Solving for Mary's age, we get   m > 32 - j.  Because j = m + 2, m > 32 - (m+2).

Continue solving for m:  Adding m to both sides of this inequality results in

2m > 32 - 2.  Then 2m > 30, and m > 15.  Mary's age is greater than 15.

\qquad\qquad\huge\underline{{\sf Answer}}

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

\qquad \sf  \dashrightarrow \: 28 : 4

to put in simple Ratio ~

\qquad \sf  \dashrightarrow \: 7: 1

So, the sides of the larger polygon are :

  • 4 × 7 = 28

  • 6 × 7 = 42

  • 3 × 7 = 21

  • 4 × 7 = 28

  • 7 × 7 = 49

  • 3 × 7 = 21

  • 3 × 7 = 21

  • 4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

\qquad \sf  \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28

\qquad \sf  \dashrightarrow \:238 \:  \: units
