Which fractions are equivalent to 10/12? Select each correct answer. ​ ​2/3​ ​5/6​ ​12/24​ ​30/36​ ​50/60​ ​60/84​
Yuri [45]

Answer:

[See Below]

Step-by-step explanation:

✦ Turn into decimals:

  • \frac{10}{12}=0.83
  • \frac{2}{3} =0.67
  • \frac{5}{6} =0.83
  • \frac{12}{24} =0.5
  • \frac{30}{36} =0.83
  • \frac{50}{60} =0.83
  • \frac{60}{84} =0.71

So \frac{10}{12} ≈ \frac{5}{6},\frac{30}{36},and,\frac{50}{60}.

Can you guys help me out on this? I'm still learning sign, cosign, and tangent :)
lara [203]

Answer:

1. 12/13 and 5/13

2. 5/13 and 12/13

3. The sin of <A and cos of <B are congruent.

Since "Sine" is Opposite/Hypotenuse and Cosine is adjacent hypotenuse...

The opposite of angle A is 12, and the hypotenuse is 12, therefore making 12/13.

The adjacent of angle B is 12, (The adjacent side is the side next to the opposite that is not the hypotenuse) and the hypotenuse is 13, therefore making 12/13.   (The hypotenuse never changes no matter how you look at the triangle.)

Sin <A = 12/13

Cos <B= 12/13

Draw 2 squares. The first one should have an area of 12 square units.The second one should have an area that is DOUBLE that of t
statuscvo [17]

Step-by-step explanation:

Given the information:

  • 1st square:  12 square units
  • 2nd square: DOUBLE that of the first square = 2*12 = 24 square units

From that, we can determine the length of the side in each square:

1/ x^{2} = 12

<=> x = 2\sqrt{3}

2/ a^{2} = 24

<=> a = 2\sqrt{6}

Please have a look at the attached photo.

Hope it will find you well.
