Ones, tens, hundreds, thousands, ten thousands

9 is your thousands,

look to the hundreds place to see if you round up or stay the same.

if that number is equal to or >5, round up, if <5 then round down

IN this case, your answer is 90000, because 6 rounds up to 1, and 9+1 = 10

Answer:90000

hope this helps

A The length of a rectangle is 4 m more

Lady bird [3.3K]

Given :

The length of a rectangle is 4m more than the width.
The area of the rectangle is 45m²

⠀

To Find :

The length and width of the rectangle.

⠀

Solution :

We know that,

$\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\:$

So,

Let's assume the length of the rectangle as x and the width will be (x – 4).

⠀

Now, Substituting the given values in the formula :

$\qquad \sf \: { \dashrightarrow x \times (x - 4) = 45 }$

$\qquad \sf \: { \dashrightarrow {x}^{2} - 4x = 45 }$

$\qquad \sf \: { \dashrightarrow {x}^{2} - 4x - 45 = 0 }$

$\qquad \sf \: { \dashrightarrow {x}^{2} - 9x+ 5 x - 45 = 0 }$

$\qquad \sf \: { \dashrightarrow x(x - 9) + 5(x - 9) = 0 }$

$\qquad \sf \: { \dashrightarrow (x - 9) (x + 5) = 0 }$

$\qquad \sf \: { \dashrightarrow x = 9, \: \: x = - 5}$

⠀

Since, The length can't be negative, so the length will be 9 which is positive.

⠀

$\qquad { \pmb{ \bf{ Length _{(rectangle)} = 9\:m}}}\:$

$\qquad { \pmb{ \bf{ Width _{(rectangle)} = 9 - 4=5\: m}}}\:$

- if you're looking for the inverse of it is -3x + 12
- if you're looking for the slope of it is m equals m=-1/3
- if you're looking for the access interception point of it is the x-intercept is (12, 0 )the Y intercepts is (0,4)

Swamp gas consists primarily of methane, a chemical compound consisting of a 1 : 4 ratio of carbon to hydrogen atoms. If a sampl

Alchen [17]

Answer:

Number of carbon atoms present in the sample are 391.

Step-by-step explanation:

We are given that,

Ratio of carbon to hydrogen atoms = 1 : 4

It is given that a sample of methane consists of 1564 hydrogen atoms.

Let the carbon atoms in the sample = x

So, we have the relation,

$\frac{Carbon}{Hydrogen}=\frac{1}{4}=\frac{x}{1564}$

i.e. $\frac{1}{4}=\frac{x}{1564}$

i.e. $x=\frac{1564}{4}}$

i.e. x= 391

Hence, the number of carbon atoms present in the sample are 391.
