<u>Answer:</u>

  • The number is 6.

<u>Solution:</u>

  • 2(x + 11) = 34
  • => 2x + 22 = 34
  • => 2x = 34 - 22
  • => 2x = 12
  • => x = 12/2
  • => x = 6

Hence, the number is 6.

What is the length of the hypotenuse of the triangle when x=14
astra-53 [7]

The length of the hypotenuse will be equal to H=122.25 when value of x=14.

<h3>What is pythagorean theorem?</h3>

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal the square of the sum of the other two sides.

It is given that:

Value of x=14

The perpendicular is  =6x+5=6x14+5=89

The base is  =6x=84

So by using the Pythagorean theorem:-

H^2=P^2+B^2\\\\\\H^2=89^2+84^2\\\\\\H=\sqrt{89^2+84^2}\\\\\

Hence the value of hypotenuse will be H=122.25

To know more about the Pythagorean theorem follow

In a math class with 29 students, a test was given the same day that an assignment was due. There were 22 students who passed th
Phoenix [80]

4/29 is the probability that a student who did not complete the homework passed the test.

<u>Step-by-step explanation:</u>

It is given that,

There are 29 students in a math class.

Two types of students who passed the test and are not passed the test.

The other two types of students are who completed the assignment and did not complete the assignment.

So, the given data can be formed as a table.

  • There were 22 students who passed the test.
  • There were 20 students who completed the assignment.
  • There were 18 students who passed the test and also completed the assignment.

                                         Passed the test     Not passed the test    Total

Completed assignment        18                             -                             20

Not completed assignment   x                             -                                -

Total                                       22                           -                               29

Now, you need to find the probability that a student who did not complete the homework passed the test.

⇒ No.of students completed assignment passed the test / Total students.

<u>To find the no.of students completed assignment passed the test :</u>

Let 'x' is the no.of students completed assignment passed the test.

⇒ 18+x = 22

⇒ x = 22 - 18

⇒ x = 4

∴ P(students completed assignment passed the test) = 4 / 29.
