In words the place that the cube root of 63 would appear on the number line would be: between 3 and 4, but closer to 4

How to find the cube root

The cube root of 63 would be gotten from a calculator when we use this formula

The solution that we would have from the calculator would be 3.97. The value 3.97 is known to be greater than 3 by a lot but just a little less than 4 on the number line.

3.97 can be approximated to be 4. Hence we can say that In words the place that the cube root of 63 would appear on the number line would be: between 3 and 4, but closer to 4

Answer: A. between 2 and 3, but closer to 2.

Step-by-step explanation:

The cube root of 24 is a number that, when multiplied by itself three times, equals 24. To determine where this cube root would be plotted on a number line, we can compare it to other numbers.

Let's start by finding the perfect cubes of some numbers. The perfect cube of 2 is 2*2*2 = 8, and the perfect cube of 3 is 3*3*3 = 27. Since 24 is between 8 and 27, we know that the cube root of 24 would be between 2 and 3 on the number line.

Now, to determine if it's closer to 2 or 3, we can consider the difference between the cube of each of these numbers and 24. The cube of 2 is 2*2*2 = 8, and the difference between 8 and 24 is 24-8 = 16. The cube of 3 is 3*3*3 = 27, and the difference between 27 and 24 is 27-24 = 3.

Since 16 is greater than 3, we can conclude that the cube root of 24 is closer to 2 than to 3. Therefore, it would be plotted on the number line between 2 and 3, but closer to 2.

Four books, one each on physics, chemistry, mathematics, and biology are about to be stacked on a shelf. If the books are stacked randomly, what is the probability the mathematics book is on top?

Answers

There are 4 books.
The math book can either be top, second from top, third from top, or on the bottom.
The probability of being in any single given position is 1/4 = 25% .

Since each book can be put on the top, and there are 4 books, the chances of a math book going on the top is 1/4, while the other 3 chances are the other books. So your answer is 1/4 or 0.25

He receives 2% commission on the first $20,000, 6% on sales from $20,000 to $70,000, 8.5% commission on sales from $70,000 to $100,000, and 10% commission on sales over $100,000. David had sales of $82,000. His commission is:rev: 08_24_2013_QC_ 34268
$8,200
$6,200
$4,240
$4,420
None of these

Answers

he receives 8.5% commission on sales from $70,000 to $100,000, therefore the commission is:
comission = 8.5%($82000) = (85/1000)(82000)
= 6979
that is his commission
