AB = BC

3x-4=5x-10
-4=2x-10
6=2x
3=x

AB = 3x-4
AB = 3 (3)-4
AB = 9-4
AB =5

Therefore, AB is 5.

BC = 5x-10
BC = 5(3)-10
BC = 15-10
BC= 5

Two geometry questions in the attached photos - If I have a line, do I have a plane? & If I have three points, do I always h
Radda [10]

Answer:

18) A: only if you have an additional point not on the line.

19) D: No, because all the points may be on the same line.

Step-by-step explanation:

There are basically 4 ways we can determine a plane and they are;

- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.

- When we have a line and a point that's not on the line

- When we have two lines that intersect each other.

- When we have two lines that are parallel to each other.

From the four conditions above, we can now answer the question;

18) You can only have a plane if there is an additional point not on the line.

Option A

19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.

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

3. Florida Strawberry Festival

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.

If a total amount is 5 7/8 and 6 people need to be fed, how much is a serving size?
PolarNik [594]

<em>Answer:</em>

47/48

<em>Explanation:</em>

Since 5 7/8 is so close to 6, it is easier to work this problem by considering the difference.

The serving size is 1/6 of the total amount, so you want to find ...

... (5 7/8) × (1/6)

Following the observation above, we can compute it as ...

... (6 - 1/8) × (1/6) = (6/6) - (1/8)×(1/6)

... = 1 - 1/48

... = <em>47/48</em>
