Answer:

<h3> (x³+2x²)/3 cm³</h3>

Step-by-step explanation:

Find the diagram attached

Volume of a pyramid = 1/3 * Base area * height

Base area = x*x

Base area = x²

Height = x+ 2

Get the volume:

Volume of the pyramid = 1/3 * x² * x+2

Volume of the pyramid =  x²(x+2)/3

<em>Volume of the pyramid  = (x³+2x²)/3 cm³</em>

3. if you want to represent geologic time with a 24-hour clock, how many years would be represented by a single second, minute a
Amanda [17]

In geologic time scale a single second = 52,083.3 years, a minute = 3,125,000 years, an hour = 187.5 million years

Geologic time, the extensive interval of time occupied by the geologic history of Earth. Formal geologic time begins at the start of the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day.

So the geologic time scale (GTS) contains different ranks of times about Earth, obviously you know this already. However, the GTS has these different ranks in order from shortest length of time to longest length of time.

The Earth is about 4.5 billion years old. We want to convert this geological time in a period of 24 hours. So, if 24 hours correspond to 4.5 billion years, then, 1 Hour= 4.5 billion / 24=187.5 million years. There are 60 minutes in an hour ∴ 1 minute =187.5 million /60=3,125,000 years finally, one second has 60 seconds ∴ 1 second=3,125,000 / 60 = 52,083.3 year.

Explain Steps. Do not answer. <br>#10 and 11<br>Questions are in the Picture
svet-max [94.6K]

Answer:

Step-by-step explanation:

For problem 10:

1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)

2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)

3. 9/x=(9+6)/10 (Substitute the given values into this equation)

4. x=6 (Use algebra to solve for x)

For problem 11:

1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)

2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)

3. 14/(14+7)=18/(18+x) (Substitute given values)

4. x=9 (Solve for x)

lmk if there are mistakes in my explanation, hope this helps :)
