Is 18:12 equivalent to 3:4

Mathematics

Mrrafil [7]4 years ago

18:12 is NOT equivalent to 3:4.

For two ratios to be equivalent, the smaller ratio needs to equal the larger one when both the numbers are multiplied by a certain value.

Since we know that 3*6 = 18, let's multiply 4 by 6 to see if it's equivalent.

4*6 = 24. Because 4*6 does not equal 12, we know that the ratios are not equivalent.

musickatia [10]

Answer: 2 rational solutions

Step-by-step explanation:

When the discriminant,  b² + 2a,  is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7

IXL Question! Brainliest + 5-star!
Nitella [24]

Step-by-step explanation:

First, count the total number of the boxes from the figure. This can be done easily by counting the number of the rows and then the number of the columns and multiplying the numbers.

=> 10 x 10 = 100 boxes.

Now, count the shaded boxes. It's 8.

Now, we calculate percentage by,

=> Selected boxes/Total boxes x 100

Putting the values,

=> 8/100 x 100

=> 8%

Find the solutions of the following equations by extracting square roots 9x2-16=0 (z-2)2-36=0
natta225 [31]

The solutions of the equation 9x² - 16 = 0is 4/3 and -4/3 and that of the equation (z - 2)^{2}  - 36 = 0 is 8 and -4.

Solving the both quadratic equations by extracting square roots:

9x^{2}  - 16 = 0

⇒ 9x^{2}  = 16                                    

∴ On taking square-root of both sides, we get

\sqrt{9x^{2} } = \sqrt{16}

⇒ 3x = +4 and 3x = -4

⇒ x = 4/3 and x = -4/3

For the equation, (z - 2)^{2}  - 36 = 0, the solution is:

(z - 2)^{2}  - 36 = 0

⇒ (z - 2)^{2}  = 36

∴ On taking square-root of both sides, we get

\sqrt{(z - 2)^{2} }  = \sqrt{36}

⇒ (z - 2) = 6 and (z - 2) = -6

⇒ z = 6 +2 and z = -6 + 2

⇒ z = 8 and z = -4

The solution of the equation 9x^{2}  - 16 = 0 is 4/3 and -4/3.

The solution of the equation (z - 2)^{2}  - 36 = 0 is 8 and -4.
