Answer:

Below!

Step-by-step explanation:

To find out which ratio is equal to 4:9, multiply anything to both the numerator and the denominator. Remember, the multiplication must be equal to both the numerator and the denominator must be the same. Please check below to understand this problem better.

=> 4:9 = 4/9 = 4 x 2/9 x 2 = 8/18 = 8:18
=> 4:9 = 4/9 = 4 x 3/9 x 3 = 12/27 = 12:27

<u>These are all examples of ratios equivalent to 4:9</u>

8x + 4 = 5x - 11

Subtract 5x from both sides:
3x + 4 = -11

Subtract 4 from both sides:
3x = -15

Divide both sides by 3:
x = -5

Answer : x = -5

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan

denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

$\theta=32.5\°$ is the the angle of elevation

$d=35.6 km$ is the horizontal distance between the plane and the radar station

$x$ is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is <u>cosine</u>:

$cos\theta=\frac{d}{x}$ because $d$ is the adjacent side of the right triangle

$cos(32.5\°)=\frac{35.6 km}{x}$

Finding $x$ :

$x=\frac{35.6 km}{cos(32.5\°)}$

$x=42.21 km$

I use 3 fifth size strips to model 3/5.I want to use tenth size strips to model an equivalent fraction.How many tenth size strip

Yuri [45]

3/5= 3 fifth size strips
You want to find an equivalent fraction with the denominator of ten, correct? Then you would multiply the fraction in a way that will allow you to have a denominator of ten.
So...
3/5*2/2=6/10
You would need 6 tenth size strips.
