Answer:

1329 students

Step-by-step explanation:

20/100 ×6645

Reduce the fraction 20/100 with 20

So..20 goes into 20 1 time and 20 into 100 5 times

1/5×6645

Use 5 as the greatest common factor now

so...5 into 5 goes 1 time and 5 into 6645 goes 1329

1/1 × 1329 = 1329

Or... you could just convert 20% into a decimal by carring the . two places to the left

which is 0.2

0.2 × 6645 = 1329

Answer:

.20

Step-by-step explanation:

The word percent literally means "Out of 100". With that being said, 20% can be written as a fraction, mixed number or whole number as follows: 1/5 (fraction), 20/100 (mixed number) or .20 (whole number).

You can see that there are 6 rock CDs, over a total of

$6+10+4+8+12 = 40$

So, the ratio of rock CDs over the total number of CDs is

$\dfrac{6}{40} = 0.15$

Which is 15%.

So, yes, the answer is A

Can someone tell me if I'm right or wrong

dem82 [27]

Step-by-step explanation:

well, it is a combination of 2 shapes.

I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.

that would be

2x2 + 6x5 = 4 + 30 = 34 cm²

but you started a valid approach too.

you "sliced" off a narrow rectangle along the whole right side. 7x2.

and that leaves now a 4x(7-2) rectangle.

so,

7x2 + 4x5 = 14 + 20 = 34 cm²

yes, this was my answer.

how did this suddenly appear as your answer ?

LUCKY_DIMON [66]

Answer:

79 soldiers

Step-by-step explanation:

Since 40 soldiers were not included in the square, the square consists of 6241 soldiers. 6241 represents the area of the square, and the rows (r) represents a side of the square. Since the area of a square = the length of the side squared, then $6241 = r^{2}$ .

So $r = \sqrt{6241}$

r = 79
