The shape that's given illustrates that the number of bricks that are needed will be 200.

<h3>How to solve the shape</h3>

From the information given, the bricks are 25 cm long and 6 cm wide and will be required to cover a path of dimension 250cm by 120 cm.

Therefore, the number of bricks required will be:

= (120 × 250) / (25 × 6)

= 200

In conclusion, the correct option is 200.

Find the length of side x in simplest radical form with a rational denominator.

alekssr [168]

Answer:

$x = \frac{2*\sqrt{3}}{3}$

Step-by-step explanation:

Reference angle = 30°

Opposite side = x

Adjacent side = 2

Apply the tan trigonometric function, thus:

$tan (30) = \frac{opp}{adj}$

$tan (30) = \frac{x}{2}$

$2 * tan (30) = x$

$2 * \frac{1}{sqrt{3}} = x$ (tan 30 = 1/√3)

$\frac{2}{sqrt{3}} = x$

Rationalize

$\frac{2* \sqrt{3}}{sqrt{3} * \sqrt{3}} = x$

$\frac{2*\sqrt{3}}{3} = x$

How do you solve 1/3x = 20 to find x

Alex

1/3x=20

1st step do the opposite of 1/3x to get it by itself. So you would do 1/3x *3/1 than you would do 3/1 *20. What you do to that side you do to the other.

2nd step 20*3=60

3rd You can check your answer by doing 1/3 *60=20

I plugged the answer in the variable to Check it
