What two ratios are equivalent to 10:18

Mathematics

10 : 18          2 into 10 is 5, 2 into 18 is 9.

5 : 9.

You can also choose to multiply 10 : 18 by 2.

2*10 : 2*18

20 : 36.

Therefore   5 : 9 and 20 : 36  are two ratios that are equivalent to 10 : 18.

Good morning!

So when we look at ratios like 10:18, we read them as "Ten out-of eighteen" and we can basically think of them like fractions.  In this case, we can look at the ratio 10:18 to mean the same thing as 10/18.  

Now let's look at the fraction 10/18.  We can see that both numbers are divisible by 2.  Therefore, we can have 10/18 = (10/2)/(18/2) = 5/9 and both fractions represent the same number/amount.  We now have one equivalent ratio to 10:18, which is 5:9.

To find another equivalent ratio, we can look at 10/18 again, then multiply both numbers by the same any number.  In this case, let's multiply both numbers by 2.  So we now have (10*2)/(18*2) = 20/36 which is the same as 20:36.

We have now found two new ratios equivalent to 10:18.
⇒ 5/9
⇒20/36

Hope this helps,

Given that the points (-1,6). (3,6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the len
Ksju [112]
Since the given coordinates are already in order,
then and two consecutive distances between the coordinates will give length and breadth,

Using distance formula,
\sqrt{ {( - 1 - 3)}^{2}  +  {(6 - 6)}^{2} }  \\  =  \sqrt{ { (- 4)}^{2} }  \\  =  \sqrt{16 }  \\  = 4
(we'll not consider the negative value since distances can't be negative)

Applying this again on 2nd and 3rd coordinates,
\sqrt{ {(3 - 3)}^{2} +  {(6 - 1)}^{2}  }  \\  =  \sqrt{ {5}^{2} }  \\  = 5
(we'll not consider the negative value since distances can't be negative)

Since length's always gotta be greater than bredth
therefore,
the difference will be 5-4= 1 units


Hence width is 1 unit shorter than length.



Note: Unit used is "unit/s"

What is the value of x in the equation −x = 2 − 3x + 6?
Wittaler [7]
-x = 2 - 3x + 6

Add 3x to both sides.

-x + 3x = 2 + 6

Simplify.

2x = 8

Divide both sides by 2.

x = 4

Step-by-step explanation:

The vertex form of a parabola can be written as

y =  {a(x - h)}^{2}  + k

where (h, k) are the coordinates of the parabola's vertex. The vertices of the functions are as follows:

a) (3, 5)

b) (-7, 3)

c) (4, 0)

d) (0, -1)

e) (-1, -5)

f) (-1, -5)
