J would equal -11
first subtract 3 so 2 is -1
then divide -1 by 11
so j=-11

This is how you solve it:

3 + j / 11 = 2

3 + j = 2 × 11

3 + j = 22

j = 22 - 3

j = 19

Now you could check your answer by substituting the value of j :

3 + j / 11 = 2

3 + 19 / 11 = 2

22/11 = 2

2 = 2

The length of the hypotenuse of a right triangle is 24. If the length of one leg is 8, what is approximate length of the other l

Verdich [7]

Something that a right triangle is characterised by is the fact that we may use Pythagoras' theorem to find the length of any one of its sides, given that we know the length of the other two sides. Here, we know the length of the hypotenuse and one other side, therefor we can easily use the theorem to solve for the remaining side.

Now, Pythagoras' Theorem is defined as follows:

c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

Given that we know that c = 24 and a = 8, we can find b by substituting c and a into the formula we defined above:

c^2 = a^2 + b^2

24^2 = 8^2 + b^2 (Substitute c = 24 and a = 8)

b^2 = 24^2 - 8^2 (Subtract 8^2 from both sides)

b = √(24^2 - 8^2) (Take the square root of both sides)

b = √512 (Evaluate 24^2 - 8^2)

b = 16√2 (Simplify √512)

= 22.627 (to three decimal places)

I wasn't sure about whether by 'approximate length' you meant for the length to be rounded to a certain number of decimal places or whether you were meant to do more of an estimate based on your knowledge of surds and powers. If you need any more clarification however don't hesitate to comment below.

im, Paco, Maria, and Jenny are standing in line for lunch. Jenny is standing between Paco and Maria, and Paco’s position in line

Zanzabum

Answer:

The person standing at the fourth position is Maria.

Step-by-step explanation:

We are given that,

There are four students standing in line for lunch namely, Tim, Paco, Maria and Jenny.

Now, as Jenny is standing between Paco and Maria.

So, we have the possibility, P J M.

Also, as Paco is standing at an odd numbered position.

So, we have, either Paco stands at 1st or 3rd position.

Further, it is given that, Tim is not standing on either end of the line.

<em>So, we get, the possibilities,</em>

P J T M and M J P T.

But, in M J P T, T=Tim is standing at the end of the line, which is not possible.

So, the final positioning is given by, P J T M.

Hence, the person standing at the fourth position is Maria.

Ryan runs 100 m two times. His times were 14.19 s and 13.78 s. Daniel runs 100 m two times. His times were 15.77 s and 16.24 s.

MakcuM [25]

14.19 + 13.78 = 27.97 seconds for Ryan

15.77 + 16.24 = 32.01 seconds for Daniel

32.01 - 27.97 = 4.04 seconds greater
