What is 923 rounded to the nearest hundred??

2 answers:

923 rounded to the nearest hundred is 900. If the number was over 950 it would be 1,000 but since it was below is closer or nearest to 900

923

The hundred digit is 9.

The digit to the right after 9 is 2. 2 is not up to 5. So we round down the digits after the 9 to 0s. The answer becomes 900.

If it were 5 or more than 5, we would have rounded up by adding 1 extra digit to the 9, to make the answer 1000.

So 923 to the nearest hundred is 900.

HELP ME PLEASE!!!!!!

Eva8 [605]

I realise this is quite late but in case you still wanted the answer, the width is 3m.

If the length is 3m longer than the width, you can write the width as x and the length as x + 3. The perimeter would be both lengths and both widths added together, so you would just write it as:
x + x + x + 3 + x + 3 = 18
4x + 6 = 18
- 6
4x = 12
÷ 4
x = 3

I hope this helps!

2x^2 +5x+3/x^2+2x+1

german

Answer:

$\frac{2x+3}{x+1}$

Step-by-step explanation:

2x² + 5x + 3 = (x + 1) (2x + 3)

x² + 2x + 1 = (x + 1) (x + 1)

(x + 1) cancels out because there is one in the denominator and the numerator, leaving you with the answer.

Hope this helps!

Write the equation of the line that passes through the given point and is parallel to the given line.

romanna [79]

<u>(Note: this answer is assuming that the equation has to be put in slope-intercept format.)</u>

Answer:

$y = \frac{1}{2} x - \frac{5}{2}$

Step-by-step explanation:

1) Let's use the point-slope formula to determine what the answer would be. To do that though, we would need two things: the slope and a point that the equation would cross through. We already have the point it would cross through, (-3,-4), based on the given information. So, in the next step, let's find the slope.

2) We know that the slope has to be parallel to the given line, $y = \frac{1}{2}x - 8$ . Remember that slopes that are parallel have the same slope - so, let's simply take the slope from the given equation. Since it's already in slope-intercept form, we know that the slope then must be $\frac{1}{2}$ .

3) Finally, let's put the slope we found and the x and y values from (-3, -4) into the point-slope formula and solve:

$(y- (-4)) = \frac{1}{2} (x - (-3))\\y + 4 = \frac{1}{2} (x + 3))\\y + 4 = \frac{1}{2}x+ \frac{3}{2} \\y = \frac{1}{2}x + \frac{3}{2} - 4\\y = \frac{1}{2}x + \frac{3}{2} - \frac{8}{2} \\y = \frac{1}{2}x - \frac{5}{2}$

Therefore, $y = \frac{1}{2}x - \frac{5}{2}$ is our answer. If you have any questions, please do not hesitate to ask!

Given the sizes of the angles as<br> specified in the picture, how large is<br> angle 1?

Dvinal [7]

100 because opposite angles are equal. The angles in the triangle above add up to 80 so the last angle must equal 100. Since angle 1 is directly opposite to that angle, it also equals 100.
