Answer:

The equation you should solve to find b is:

Option D. sin 35° / 9 = sin 40° / b

Step-by-step explanation:

m<A=35°

m<B=40°

a=9

b=?

We can use the Law of sines:

sin A / a = sin B / b

Replacing the given values:

sin 35° / 9 = sin 40° / b

Which of the following pairs of numbers contains like fractions? A. 5⁄6 and 10⁄12 B. 3⁄2 and 2⁄3 C. 3 1⁄2 and 4 4⁄4 D. 6⁄7 and 1
ElenaW [278]
<h2>Hello!</h2>

The answers are:

A.

\frac{5}{6} and \frac{10}{12}

D.

\frac{6}{7} and 1\frac{5}{7}

<h2>Why?</h2>

To find which of the following pairs of numbers contains like fractions, we must remember that like fractions are the fractions that share the same denominator.

We are given two fractions that are like fractions. Those fractions are:

Option A.

\frac{5}{6} and \frac{10}{12}

We have that:

\frac{10}{12}=\frac{5}{6}

So, we have that the pairs of numbers

\frac{5}{6}

and

\frac{5}{6}

Share the same denominator, which is equal to 6, so, the pairs of numbers contains like fractions.

Option D.

\frac{6}{7} and 1\frac{5}{7}

We have that:

1\frac{5}{7}=1+\frac{5}{7}=\frac{7+5}{7}=\frac{12}{7}

So, we have that the pair of numbers

\frac{6}{7}

and

\frac{12}{7}

Share the same denominator, which is equal to 7, so, the pairs of numbers constains like fractions.

Also, we have that the other given options are not like fractions since both pairs of numbers do not share the same denominator.

The other options are:

\frac{3}{2},\frac{2}{3}

and

3\frac{1}{2},4\frac{4}{4}

We can see that both pairs of numbers do not share the same denominator so, they do not contain like fractions.

Hence, the answers are:

A.

\frac{5}{6} and \frac{10}{12}

D.

\frac{6}{7} and 1\frac{5}{7}

What is k/5.2 + 81.9= 47.2
weqwewe [10]
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)

k/5.2+81.9 = 47.2 // - 47.2

k/5.2-47.2+81.9 = 0

0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2

0.19230769*k = -(81.9-47.2) // : 0.19230769

k = (-(81.9-47.2))/0.19230769

k = 5.20000006*(47.2-81.9)

k = 5.20000006*(47.2-81.9)

Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>brainly.com/question/253764
