Answer:

5, 5/2

Step-by-step explanation:

80 becomes 40 if multiplied by 1/2; 40 becomes 20 if mult. by 1/2; and so on.

Thus, the common ratio of this geometric sequence is 1/2.

1/2 times 10 is 5;

1/2 times 5 is 5/2.

Looks like this is Answer C.  Please note:  your "5, 5 2" is not a correct representation of "5, 5/2."  Please use " / " to indicate division.

1. Describe the impromptu speech. What are its major features?
Fantom [35]

Answer: Down Below

Step-by-step explanation:

1. An impromptu speech, by definition, is the one that a speaker delivers without any prior preparation on the topic. Impromptu, itself, means “doing something without preparation”. In declamation contests, a random topic is fired at the speaker on the spot, and the speaker gets just a few seconds to think over the topic.

2. Lack of Gestures. The most common problem with public speakers is the statue like position, which they assume on the stage.

Lack of Energy.

No Rapport with Audience.

Use of Notes.

No Eye Contact.

Disrespect for Fellow Speakers.

Rushing with Words

The Florida Strawberry Festival is an 11-day community event celebrating the strawberry harvest of Eastern Hillsborough County. Each year, over 500,000 visitors enjoy the festival's headline entertainment, youth livestock shows, rides, exhibits of commerce and, of course, its strawberry shortcake.

4. Done without being planned, organised, or rehearsed.

5. What makes impromptu speech different from an extemporaneous speech?

The difference is in the delivery method: the impromptu speech is generated instantly and delivered immediately; whereas, the extemporaneous speech is delivered using just a few notes.

Write 0.4% as a fraction in simplest form.
maria [59]
To find the decimal form of a percentage, you divide by 100.  If you have a decimal, then to divide by 100 just move the decimal 2 places to the left.

0.4% = .004

Now to turn it into a fraction, just read the place value...
four one thousandths = 4/1000

Now reduce... 4/1000 = 2/500 = 1/250

The simplest form of 0.4% as a fraction is...    1/250
