How to put 412.638 in expanded form using decimals

sergeinik [125]

The <em>correct answer</em> is:

400 + 10 + 2 + 0.6 + 0.03 + 0.008.

Explanation:

To write a number in expanded form, we use place values.

4 is in the hundreds place; this makes its value 400.

1 is in the tens place; this makes its value 10.

2 is in the ones place; this makes its value 2.

6 is in the tenths place; this makes its value 0.6.

3 is in the hundredths place; this makes its value 0.03.

8 is in the thousandths place; this makes its value 0.008.

To write this together, we find the sum:

400 + 10 + 2 + 0.6 + 0.03 + 0.008.

Ivan

Answer:

6 inches.

Step-by-step explanation:

Let a represent side length of larger square.

We know that area of square is square of its side length, so area of the larger square will be $a^2$ .

The area of smaller square would be $4^2$ .

We will use proportions to solve our given problem.

$\frac{\text{Area of smaller square}}{\text{Area of larger square}}=\frac{4}{9}$

$\frac{4^2}{a^2}=\frac{4}{9}$

$\frac{16}{a^2}=\frac{4}{9}$

Cross multiply:

$4*a^2=16*9$

$\frac{4*a^2}{4}=\frac{16*9}{4}$

$a^2=36$

Take square root:

$a=\pm\sqrt{36}$

$a=\pm 6$

Since the length cannot be negative, therefore, the side length of larger square is 6 inches.

The size of a television screen is measured by the length of thee diagonal of the screen. What size is a television screen that

Murljashka [212]

Answer:

approximately 6.708 feet

Step-by-step explanation:

We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:

$diagonal = \sqrt{(3\,ft)^2+(6\,ft)^2} \\diagonal = \sqrt{9\,ft^2+36\,ft^2} \\diagonal = \sqrt{45} \,ft\\diagonal = 3\,\sqrt{5} \,ft$

which is approximately 6.708 feet
