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}.

Which of the following represents 4x^5/6 in radical form
mash [69]
Remember, order of operations
exponent before multiply

so 4x^5/6=4 times x^5/6
simplify the x^5/6 first

remember
x^\frac{m}{n}=\sqrt[n]{s^m}

so
x^\frac{5}{6}=\sqrt[6]{x^5}

so
4x^\frac{5}{6}=4\sqrt[6]{x^5}

In the triangle XYZ the measure of angle YXZ is 50 degrees and the measure of angle XYZ is 75 degrees. What is the measure of an
lbvjy [14]
<h2>Answer: 55 degrees</h2>

Step-by-step explanation:

Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles \theta, \alpha and \beta:

\theta+\alpha+\beta=180\º

Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:

XYZ+YXZ+XZY=180\º

50\º+75\º+XZY=180\º

XZY=180\º-50\º-75\º

Finally:

XZY=55\º
