Answer:

enrollment decreases by 14.34%.

Step-by-step explanation:

Given that number of students enrolled in 2000 = 823

Given that number of students enrolled in 2010 = 705

705 is less than 823 so that means number of students enrollment is decreasing.


Decrease = 823-705 = 118

Percent decrease is given by formula:

Percent =\frac{part}{whole}\cdot100 =\frac{118}{823}\cdot100= 14.3377885784

which is approx 14.34%.

Hence final answer is that enrollment decreases by 14.34%

Find the point, M, that divides segment AB into a ratio of 5:2 if A is at (1, 2) and B is at (8, 16).
d1i1m1o1n [39]
Since M divides segment AB into a ratio of 5:2, we can say that M is 5/(5+2) of the length of AB. Therefore 5/7 × AB.
distance of AB = d
5/7×(x2 - x1) for the x and 5/7×(y2 - y1) for the y
5/7×(8 - 1) = 5/7 (7) = 5 for the x
and 5/7×(16 - 2) = 5/7 (14) = 10 for the y
But remember the line AB starts at A (1, 2),
so add 1 to the x: 5+1 = 6
and add 2 to the y: 10+2 = 12
Therefore the point M lies exactly at...
A) (6, 12)

Ella collects 50 bottles to recycle. Of the bottles she collects, 19 are plastic and the rest are glass.
nekit [7.7K]
QUESTION A

The total number of bottles Ella collected is
50


The number of bottles that are plastic is

19

The percentage of bottles that are plastic is

=  \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes}  \times 100\%

=  \frac{19}{50}  \times 100\%

= 19 \times 2\%
= 38\%

Therefore 38% of the bottles are plastic.



QUESTION B

The total number of bottles that are glass is
50 - 19 = 31

The total number of bottles Ella collected is
50

The percentage of bottles that is glass is
=  \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles}  \times 100\%

=  \frac{31}{50}  \times 100\%

= 31 \times 2\%
= 62\%

Therefore 62% of the bottles are glass
