Answer:

The answer is option 3 .

Step-by-step explanation:

In order to find x, you have to use Pythogaras Theorem, c² = a² + b² :

{c}^{2}  =  {a}^{2}  +  {b}^{2}

Let a = 9,

Let b = 7,

Let c = x

{x}^{2}  =  {9}^{2}  +  {7}^{2}

{x}^{2}  = 81 + 49

{x}^{2}  = 130

x =  \sqrt{130}

Answer:

x= square root of 130

Step-by-step explanation:

a^2+b^2=c^2

a=7 b=9 c=x

49+81=x^2

130=x^2

square root of 130=x

Given:

LMN is an equilateral triangle.

LM = LN = MN = 12 cm

To find:

The height of the triangle h.

Solution:

In a right angle triangle,

\sin \theta=\dfrac{Opposite}{Hypotenuse}

\sin (60^\circ)=\dfrac{h}{12}

\dfrac{\sqrt{3}}{2}=\dfrac{h}{12}

Multiply both sides by 12.

\dfrac{\sqrt{3}}{2}\times 12=\dfrac{h}{12}\times 12

6\sqrt{3}=h

Therefore, the height of the triangle is 6\sqrt{3} cm.

Draw a picture to show the product of 4:7 x 3. Then write the product
Hoochie [10]

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.  

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇  pie.

∴ ⁴/₇ × 3 = ¹²/₇

Hence in 9 hours, Miguel drew (2/3)* 9 = 18/3=6 cartoon cells .

So the answer of the given question is 6 cartoon cells .
