Draw out a horizontal line. Place 0 at the center. Then place evenly spaced tick marks on either side of 0. Label the right side of tick marks as 1, 2, 3, ... moving from 0 and going to the right

Label the left side of tick marks -1, -2, -3, ... starting at 0 and moving left

The location -3 on the number line is exactly 3 units away from 0. We start at 0 and move to -3 by moving 3 spots to the left; or we start at -3 and move 3 units to the right to get to 0.

Therefore, the absolute value of -3 is 3
Absolute value on a number line is the distance a number is from 0
The distance is never negative

Multiplying and Dividing by Powers of 10 When multiplying a number by 10, move the decimal to the right. When multiplying a numb

just olya [345]

Answer:

Because we actually divide by 10 when a number is multiplied by 0.1.

Step-by-step explanation:

Let $a$ be a number.

When we multiply a number by 10:

$a \times 10 = 10 a$ (One '0' is increased in the number)

For example:

$23 \times 10 = 230$

Considering a decimal number:

$2.3 \times 10 = 23$

Multiplying a number with 0.1 (which is actually $\frac{1}{10}$ ) means dividing the number by 10.

$23\times 0.1 =23\times \frac{1}{10}=2.3$

Considering a decimal number:

$2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23$

<em>Therefore, When multiplying a number by 0.1, move the decimal to the left.</em>

Which of the expressions below has a 1 in the thousandths place of the sum? Select all that apply. A) 32.474 + 16.577 B) 23.452

Paraphin [41]

Answer:

A) 32.474 + 16.577

= 49.051

C) 19.213 + 4.578

= 23.791

Step-by-step explanation:

Place value may be defined as the positional system of a notation where the position of any number with reference to the decimal point determines the value of that number.

A) 32.474 + 16.577

= 49.051

B) 23.452 + 31.561

= 55.013

C) 19.213 + 4.578

= 23.791

D) 8.128 + 9.192

= 17.32

We have to find the expression which contains 1 in the thousandths place in the sum.

We know after the decimal point, the place value are designated as tenths, hundredths, thousandths, and so on.

Therefore, A). 49.051 and C). 23.791 has a place value of 1 in its thousandths place.

Answer: C

Step-by-step explanation: 0.571 is greater than 0.4. Therefore, 4/7 is greater than 2/5 and the answer to the question "Is 4/7 greater than 2/5?" is yes. Note: When comparing fractions such as 4/7 and 2/5, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.

Which polynomial is a quadratic trinomial?

il63 [147K]

<h3>Answer: Choice C</h3>

The largest exponent here is 4, so that makes it a quartic.

There are 3 terms, so we have a trinomial. Each term is separated by either a plus or a minus.

Choice A shows a quartic polynomial. Choice B is a cubic polynomial. Choice d is a quadratic trinomial.
