How do cnidaria feed,move, and reproduce

Nady [450]

Answer:

Cnidarians do not have true organs, however. Reproduction is by asexual budding (polyps) or sexual formation of gametes (medusae, some polyps). The result of sexual reproduction is a larva, which can swim on its own.

Tom decides to paint one wall in his room green. Use the dimensions below to calculate the area of the this wall.

Anton [14]

Option C:

Area of the wall $=94\frac{15}{16}$ square feet

Solution:

Length of the wall = $12 \frac{1}{4}$ feet

Width of the wall = $7 \frac{3}{4}$ feet

Area of the wall = length × width

$$=12 \frac{1}{4}\times 7 \frac{3}{4}$

Convert mixed fraction into improper fraction.

$$=\frac{12 \times 4+1}{4}\times \frac{7\times 4+3}{4}$

$$=\frac{49}{4}\times \frac{31}{4}$

$$=\frac{1519}{16}$

Convert improper fraction into mixed fraction.

$$=94\frac{15}{16}$

Area of the wall $=94\frac{15}{16}$ square feet

Option C is the correct answer.

Identify the values of a, b, and c in this quadratic equation:

riadik2000 [5.3K]

Answer:

a = 1 : b=-8; C = 12

Step-by-step explanation:

I think you did not include the sign between the x^2 and the 8x...my guess is that it is a minus.

By process of elimination the answer is not B or D bc the a-value is 1 not 0.

Then the +12 you did include in the original question indicates that the c-value is 12 not -12 eliminating answer A.

A restaurant serves custom-made omelets, where guests select meat, cheese, and vegetables to be added to their omelet. There are

FrozenT [24]

Answer:

15 possible combinations

Step-by-step explanation:

Given

$Vegetables = 6$

$Selection = 2$

Required

Determine the possible number of combinations

The question emphasizes on "selection" which means "combination".

So; To answer this question, we apply the following combination formula:

$^nC_r = \frac{n!}{(n-r)r!}$

In this case:

$n = 6$

$r = 2$

The formula becomes:

$^6C_2 = \frac{6!}{(6-2)!2!}$

$^6C_2 = \frac{6!}{4!2!}$

$^6C_2 = \frac{6*5*4!}{4!2*1}$

$^6C_2 = \frac{6*5}{2}$

$^6C_2 = \frac{30}{2}$

$^6C_2 = 15$

<em>Hence, there are 15 possible combinations</em>
