When rounding to the nearest hundred, which of the following numbers round to 400?

2 answers:

6 0

When rounding numbers up or down, you need to look at the number in the place to the right of the place you are rounding to.

You have been asked to round to the nearest hundred (3rd place from the right)

Look one place to the right of the hundred place (the ten's place in this instance). If it is 4 or less, you will leave the hundred's digit as is and fill in the tens and ones places with a zero (this is called rounding down).

If it is 5 or higher, you will "round up" the digit in the hundred's place to the next hundred.

348 has a 4 in the tens place - so we will "round down" by leaving the hundred digit and placing zeros in the tens and ones. (300)

452 rounds up to 500 (because of the 5 in the tens place)

325 rounds down...

423 rounds down...

351 rounds up to ... 400! We found our answer

445 rounds down...

The answer is 423 since it's the closest number to 400 from all the numbers listed above.

The numbers 351 and 445 would also round to 400 but they are not the closest ones.

Hope it helped,

Angles 1, 3, and 4 make up a straight line.
Thus, 3x + 90 + 3x - 6 = 180 (angle sum of straight line)
6x - 6 = 90
6x = 96

x = 16
Now angle 1 becomes 3(16) = 48
Angle 1, 2, and 3 also make up a straight line.
Thus, angle 2 + 48 + 90 = 180
angle 2 + 138 = 180
angle 2, therefore, becomes 42. In essence, (A)

Write each fraction as a sum or difference 14-6x/19

Oksanka [162]

Given number : 14 - 6x / 19
So we need to write this fraction as a sum or difference.
First, simplify the given number:
=> 14 – 6x / 19
=> 14 x 19 – (6x)
 19
=> 266 – 6x
 19
=> 266 – 6x = -2 * (3x - 133)
Thus, the final result would be:
=> -2 * (3x - 133) => This will be the fraction sum or difference of the given number
 19

The ratio of the width to the length of a rectangle is 2:3, respectively. Answer each of the following. a By what percent would

Elina [12.6K]

Answer:

The percentage increase in Area of rectangle is 200%

Step-by-step explanation:

Given as :

The ratio of the width to the length of a rectangle is 2:3

Let The length of rectangle = 2 x

Let The width of rectangle = 3 x

∵ Area of rectangle = length × width

So, $A_1$ = 2 x × 3 x

Or, $A_1$ = 6 x²

Again

The increased length of rectangle = 2 x + 2 x = 4 x

The increase width of rectangle = 3 x + 50% of 3 x

I.e The increase width of rectangle = 3 x + 1.5 x = 4.5 x

∵ Increased Area of rectangle = increased length × increased width

Or, $A_2$ = 4 x × 4.5 x = 18 x²

So, The percentage increase in area = $\dfrac{A_2 - A_1}{A_1}$ × 100

Or, The percentage increase in area = $\frac{18 x^{2}-6x^{2}}{6x^{2}}$ × 100

Or , The percentage increase in area = $\dfrac{12}{6}$ × 100

∴ The percentage increase in area = 200

Hence, The percentage increase in Area of rectangle is 200% Answer
