Answer:

\frac{2}{7} x = 300

Step-by-step explanation:

Let x = the number of all the species of birds sighted in the park

“300 species of birds that migrate. This accounts for 2/7 of all the species of birds sighted in the park”

the above sentence means “(2/7)x = 300”

now we can solve it :

(2/7)x = 300

⇔ 2x = 7×300

⇔ 2x = 2100

⇔ x = 2100/2

⇔ x = 1050

2 complementary angles are in the ratio 7:8.find the angles
slavikrds [6]
Complementary angles add up to 90 degrees
7:8....added = 15

7/15 * 90 = 630/15 = 42 <== one angle is 42 degrees
8/15 * 90 = 720/15 = 48 <== other angle is 48 degrees

Find the common ratio of the geometric sequence 18,-72,288,...
tamaranim1 [39]

Answer:

<em>The common ratio of the geometric sequence is -4</em>

Step-by-step explanation:

<u>Geometric Sequence</u>

A geometric sequence is defined as a series of numbers that follow a fixed pattern: Each term equals the previous term times a fixed number called the common ratio. The recursive formula is:

a_n=a_{n-1}*r

Where r is the common ratio.

We are given three terms of a geometric sequence:

18,-72,288,...

To find the common ratio, just divide each term by the previous term:

\displaystyle r=\frac{-72}{18}=-4

Make sure it's a fixed number and test with the third term:

\displaystyle r=\frac{288}{-72}=-4

Since both numbers coincide, the common ratio of the geometric sequence is -4
