Answer:

Choice A. $\frac{2}{3}$

Step-by-step explanation:

Turn the mixed numbers into improper fractions:

$\frac{14}{9} /\frac{7}{3}$

Flip the second term and multiply:

$\frac{14}{9} /\frac{3}{7}$
$\frac{42}{63}$

Simplify:

$\frac{2}{3}$

Of the students attending a school party, 60% of the students are girls, and 40% of the students like to dance. After these stud

elena-s [515]

Answer:

252 students at the party like to dance

Step-by-step explanation:

Given:

60% of the students are girls

40% of the students like to dance

20 more boy students

Percentage of the girls in the party = 58%

To Find:

How many students now at the party like to dance=?

Solution:

Let the number of girls be g.

Let the number of total people originally be t.

We know that

$\frac{g}{t}=\frac{60}{100}$

$\frac{g}{t}=\frac{3}{5}$ ----------------------------------(1)

We also know that

$\frac{g}{t+20}=\frac{58}{100}$

$\frac{g}{t+20}=\frac{29}{50}$ -----------------------------(2)

We now have a system of equation from (1) and (2)

3t=5g

$g = \frac{3t}{5}$ ------------------------(3)

50g=29t+580------------------------(4)

Substituting 3 in 4, we get

$50(\frac{3t}{5})=29t+580$

$(\frac{150t}{5})=29t+580$

$30t =29t+580$

$30t -29t = 580$

t =589

So originally there was 580 students

In this 580 students 40% liked to dance

Then the number of students liked to dance =

=> $40\% \text{of} 580$

=> $\frac{40}{100} \times 580$

=> $0.4 \times 580$

=> 232

We also know that with these people, 20 boys joined, all of whom like to dance.

Now the number of students like to dance = 232+20 = 252 students

romanna [79]

The distance from E to side AD is 25/13.

<h3>What is a distance?</h3>

The length of the line connecting two places is the distance between them.
If the two points are on the same horizontal or vertical line, the distance can be calculated by subtracting the non-identical values.

To find what is the distance from E to side AD:

If you draw a diagram, you'll see that triangle AEB is a right triangle with lengths 5, 12, and 13.
Let's call F the point where E meets side AD, so the problem is to find the length of EF.
By Angle-Angle Similarity, triangle AFE is similar to triangle BEA. (the right angles are congruent, and both angle FAE and ABE are complementary to angle BAE)
Since they're similar, the ratios of their side lengths are the same.
EF/EA = EA/AB (they're corresponding side lengths of similar triangles).

Substitute them with known lengths:

EF/5 = 5/13
EF = 5 × (5/13) = 25/13

Therefore, the distance from E to side AD is 25/13.

The correct answer is given below:
Square ABCD has side lengths of 13 units. Point E lies in the interior of the square such that AE=5 units and BE=12 units. What is the distance from E to side AD? Express your answer as a mixed number.
