Answer:

Perimeter = 54.6 cm

Area = 173 cm²

Step-by-step explanation:

sin 30 = x/20

x = 10

cos 30 = y /20

y = 17.3

perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm

area = 10 * 17.3 = 173 cm²

Mrrafil [7]

Answer:

D. 504

Step-by-step explanation:

Let the number of days = x

Now, the number of students doubles each day for the two weeks with the initial number of students having measles = 8.

So, we have,

Days (x) Cases doubled Number of Students

1 8 8

2 8 × 2 16

3 16 × 2 32

4 32 × 2 64

So, we get the geometric series as 8, 16, 32, 64,...... for two weeks.

Then, the common ratio = $\frac{16}{8}=\frac{32}{16}$ = 2

Thus, Number of students = $8\times \frac{(1-2^6)}{1-2}$

i.e. Number of students = $8\times \frac{(1-64)}{-1}$

i.e. Number of students = $8\times \frac{(-63)}{-1}$

i.e. Number of students = 8 × 63 = 504

Hence, the number of students having measles at the end of the 6th day are 504.
