How do I do a ratio?​
Kamila [148]
A ratio is comparing one thing to another (numbers in this case). You can write ratios in many ways
here’s three different ways.
There are four girls and and 2 boys.
The ratio of girls to boys is:
4:2
4 to 2
4/2

*THE RATIO MUST ALWAYS BE IN ORDER!!! If boys come first in the problem WRITE THE BOYS NUMBER FIRST! If girls come first, WRITE THE GIRLS FIRST IN THE RATIO!!! (That’s a very common mistake) hope this helps!

Solve the equation for 0° ≤ x ≤ 90°. Round to the nearest degree. tan^2 B = 4
Anettt [7]

<u>ANSWER</u>

B=63\degree


<u>EXPLANATION</u>

We want to solve the trigonometric equation;


tan^2(B)=4, where 0\degree \le B \le 90\degree.


Taking square root of both sides gives,


tan(B)=\pm \sqrt{4}


tan(B)=\pm 2


Since B is in the first quadrant, we proceed with;


tan(B)=2, because the tangent ratio is positive in the first quadrant.


\Rightarrow B =arctan(2)


\Rightarrow B =63.43\degree.


Correct to the nearest degree,


B =63\degree

This is a little difficult for me! Can someone explain?
ch4aika [34]

Answer:

We can write sin 21° as 1200 / x and also 0.36 so we can write:

1200 / x = 0.36

1200 = 0.36x

x = 1200 / 0.36

x ≈ 3333 ft

1. For the shown triangle, AD is 42, MD is 27, AN is 20 and NG is 3x+3.
GuDViN [60]

Answer:

  • 11

Step-by-step explanation:

<u>According to triangle similarity, corresponding sides have equal ratios.</u>

  • AM/AD = AN/AG

<u>Convert the ratio as below:</u>

  • (AD - MD)/AD = AN/(AN + NG)
  • (42 - 27)/42 = 20/(20 + 3x + 3)

<u>Simplify and solve for x:</u>

  • 15/42 = 20/(3x + 23)
  • 5/14 = 20/(3x + 23)
  • 1/14 = 4/(3x + 23)
  • 3x + 23 = 4*14
  • 3x + 23 = 56
  • 3x = 33
  • x = 11
