Compare the method of using expanded form and the method of using place value to multiply a decimal and a whole number????
Answers
Example:
110 x 10500
100 + 10 x 10000 + 500 = 1155000
Place value is arranging it according to the highest number place value to lowest
like,
10
* 5
-----
50
The multiplication of whole number and decimal expansion can be obtained by the use of base-ten system.
Further explanation:
The whole numbers is the series of numbers that starts from zero.
Given:
Explanation:
The place values are only natural numbers.
The base ten systems represent the position of a place value.
After decimal the first place is the tenth place, the second place is the hundredth and the third place is the thousandth.
Consider the decimal form is and consider a whole number as
The expanding of can be expressed as follows,
Now multiply 0.23 by 5.
The multiplication of whole number and decimal expansion can be obtained by the use of base-ten system.

The area of table is 78.5 square inches.
What is area?
A figure's area is the amount of space it takes up in two dimensions. To put it another way, it is the number that tells how many unit squares cover the surface of a closed figure. Square units, such as square inches, square feet, and so on, are the standard measurement for area.
Given the diameter of dinner plate = 10 inches
shape of plate is circular
area of circle is πr²
where r is radius
r = d/2 = 10/2 = 5 inches
A = πr²
A = 3.14(5)²
A = 3.14 x 25
A = 78.5 square inches
Hence area is 78.5 square inches.

After the 'n'th bounce, the ball returns to a maximum height of
(100) times (0.75)^n .
-- After 4 bounces, the maximum height is (100) (0.75)^4 = 31.64 inches.
-- To look for the maximum height of 1 inch, (100) (0.75)^x = 1
Let's take the log of each side: log(100) + x log(0.75) = 0
Subtract log(100) from each side: x log(0.75) = -log(100)
Divide each side by log(0.75) : x = -log(100) / log(0.75).
log(100) = 2 . So ... x = -2 / log(0.75) = -2 / -0.124939 = 16.00785
So the ball returns to a slim hair more than 1 inch high on the 16th bounce,
and returns to definitely less than 1 inch high on the 17th bounce.

Answer:To solve this problem, we need to standardize the values of 55 and 63 to z-scores and then use the standard normal distribution table to find the area between those two z-scores.
The z-score for a value of 55 is:
z = (55 - 62) / 4 = -1.75
The z-score for a value of 63 is:
z = (63 - 62) / 4 = 0.25
Using a standard normal distribution table, we can find that the area to the left of z = -1.75 is 0.0401 and the area to the left of z = 0.25 is 0.5987. Therefore, the area between z = -1.75 and z = 0.25 is:
0.5987 - 0.0401 = 0.5586
To convert this area back to a percentage, we multiply by 100:
0.5586 * 100 ≈ 55.9%
Therefore, the answer is A. 55.9%.

If the function is f(x) = 3 / (x + 4), a table could be
x f(x)
-8 -3/4
-7 -1
-6 -3/2
-5 -1
(-4 is no a valid input)
- 3 3
- 2 3/2
-1 1
0 3/4
1 3/5
2 3/6 = 1/2
3 3/7
4 3/8
If the function is f(x) = (3/x) + 4
Just substitute different values for x and obtain the respective outputs. In this case, x has to be different of o, i.e. 0 is not a valid input.
The answer is option B in the screenshot.
