liraira [26]

A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!

3. What are the identification numbers for ten students chosen at random from a population of 78 students based on the following
Naya [18.7K]

Answer:

27 67 16 01 27 35 21 37 74 10

Step-by-step explanation:

Starting from the left, you pick two numbers together and skip two numbers if it is greater than 78.

Meaning:

27816 78416 01822 73521 37741 016312 68000 53645 56644 97892 63408 77919 44575

You pick [27] and leave 81 since it is greater than 78, the population number.

Then you pick [67] and leave 84 as it is also greater than 78.

Then you pick [16] and [01] but leave 82, as it is greater than 78.

Then pick [27], [35], [21], [37], [74] and [10] since they are all less than 78.

At this juncture, you have identified 10 numbers: 27 67 16 01 27 35 21 37 74 10

THE VOLUME OF A CONE IS 15 PI CUBIC METERS. WHAT IS THE VOLUME OF A CYLINDER HAVING THE SAME BASE AND SAME HEIGHT?
Drupady [299]
Okay, so I know that you either multiply the volume of a cone by 3 to get the cylinders volume, or you divide it. I think you multiply it. Just remember, the rule is to multiply the volume of a cone by 3, to get the cylinder volume with the same measurements. So 15 x 3.

4^5*7^10 RAISED TO SINGLE POWER
Westkost [7]
<h3>Answer:   4^15</h3>

Explanation:

The rule used is

a^b*a^c = a^(b+c)

Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.

Using the rule, we get

a^b*a^c = a^(b+c)

4^5*4^10 = 4^(5+10)

4^5*4^10 = 4^15
