Answer:

If this is a normal triangle, it is impossible to solve for unique x.

However, if this is a right triangle with hypotenuse = 40 ft as shown in picture, then, by applying Pythagorean theorem, we have:

(3x)^2 + (6x)^2 = 40^2

<=> 9x^2 + 36x^2 =40^2

<=> 45x^2 =40^2

<=> x^2 = (40/45)^2

<=> x = 40/45

And the two side lengths would be :

6 x 40/45 = 6 x 8/9 = 48/9 = 16/3 = 5.3 ft

3 x 40/45 = 3 x 8/9 = 24/9 = 8/3 = 2.7 ft

Hope this helps!

Answer:

x = 35.6

3x = 106.7

6x = 213.3

Step-by-step explanation:

Using pythagoras theorem

(6x)² + (3x)² = 40²

36x² + 9x² = 1600

45x² = 1600

x² = 320/9

x = 35.555555

3x = 106.66666

6x = 213.3333

I need help ASAP if you can help you are amazing.

Answer (Note: the bold are answers):

First question answer:

Point = (3,1)

Slope = 3

y = 3x + b

(1) = 3(3) + b

1 = 9 + b

1 - 9 = b

-8 = b

y = 3x - 8

The second question answer:

y = mx + b

Get two points:

(3,-7) and (4,-11)

m = -11 - (-7) / 4 - 3

m = -11 + 7 / 1

m = -4 / 1

m = -4

b = + 3

y = -4x + 3

When there are variables with exponents on the bottom you have to subtract the ones on the bottom from the ones on the top. Then if the exponent is negative you have to flip it.

a coin lands on heads 200 times. the relative frequency of heads is 0.4. how many times was the coin thrown?
Kazeer [188]

Answer:

The number of times coin thrown was <u>500</u>.

Step-by-step explanation:

Given:

A coin lands on heads 200 times. the relative frequency of heads is 0.4.

Now, to find the times coin was thrown.

Let the number of times coin thrown was be x.

Relative frequency = 0.4.

Number of lands on heads = 200.

So, to get the number of times coin was thrown we put formula:

Relative\ frequency=\frac{Number\ of\ lands\ on\ heads}{Number\ of\ times\ coin\ thrown}

0.4=\frac{200}{x}

<em>By cross multiplying we get:</em>

0.4x=200

<em>Dividing both sides by 0.4 we get:</em>

x=500.

Therefore, the number of times coin thrown was 500.
