You can fit 48 books on the shelf.

Step-by-step explanation:

First convert 3 feet to inches.

Now divide 36 inches by 3/4 inches

(36in) / (3/4in)

36 x (4/3) = 48

Find the roots of this equation 7xsquare - 5x - 2 = 0
Sophie [7]

Answer:

x = 1, -2/7

Step-by-step explanation:

You could use the quadratic equation but this can be factored into

(7x + 2) (x - 1).  You can verify that by multiplying it out.

Since (7x + 2) (x - 1) = 0, if either factor is 0 then the equation would be equal to 0, thus we get x = 1, -2/7

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess
statuscvo [17]
Let's start by visualising this concept.

Number of grains on square:
1   2   4   8   16 ...

We can see that it starts to form a geometric sequence, with the common ratio being 2.

For the first question, we simply want the fifteenth term, so we just use the nth term geometric form:
T_n = ar^{n - 1}
T_{15} = 2^{14} = 16384

Thus, there are 16, 384 grains on the fifteenth square.

The second question begs the same process, only this time, it's a summation. Using our sum to n terms of geometric sequence, we get:
S_n = \frac{a(r^{n} - 1)}{r - 1}
S_{15} = \frac{2^{15} - 1}{2 - 1}
S_{15} = 2^{15} - 1 = 32767

Thus, there are 32, 767 total grains on the first 15 squares, and you should be able to work the rest from here.

Explain how your knowledge of place value helps you divide a number in the thousands by whole numbers to 10 give an example to s
lapo4ka [179]

Answer with Step-by-step explanation:

The value of a digit due to its position in a number is called as place value.

For example, there's a number

23450

2 is in ten thousands place and it has a place value of 20,000

3 is in thousands place and it has a place value of 3000

4 is in hundreds place and it has a place value of 400

5 is in tens place and has a place value of 50

0 is in unit or ones place and has a value of 0

When we divide the number by 10, we move every digit from its current place value to the right.

23450 divided by 10 = 2345

Now,

2 is in thousands place and it has a place value of 2,000

3 is in hundreds place and it has a place value of 300

4 is in tens place and it has a place value of 40

5 is in unit or ones place and has a place value of 5
