PLEASE HELP WITH NUMBER 11 ASAP!!!! (Please show how you got the answer)
Alex777 [14]

Answer:

Triangle B is right

Step-by-step explanation:

Using the converse theorem of Pythagoras.

If the square of the longest side in a triangle equals the sum of the squares of the other 2 sides then the triangle is right.

Triangle A

longest side squared = 36² = 1296

26² + 18² = 676 + 324 = 1000 ≠ 1296

Hence triangle A is not right

Triangle B

longest side squared = 25² = 625

20² + 15² = 400 + 225 = 625 ← correct

Hence triangle B is right

Solve for X<br> 1) 5<br> 2) 6<br> 3) 4<br> 4) 3
Molodets [167]

Answer:

x = 4

Step-by-step explanation:

given 2 chords intersecting inside a circle , then

the product of the parts of one chord is equal to the product of the parts of the other chord, that is

9 × 4x = 8(4x + 2)

36x = 32x + 16 ( subtract 32x from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

How many movies are 120 minutes or less in length?
borishaifa [10]

The movies of 120 min or less than 120 mins are 100

Further explanation:

A histogram is a visual representation of data.

In the given histogram we can see that

5 movies are 0 to 30 minutes, 10 movies are 31 to 60 minutes, 30 movies are 61 to 90 minutes, 55 movies are 91 to 120 minutes, and 15 movies are over 120 minutes.

In order to find the number of movies which are 120 minutes long or less than 120 minutes we will add up all the number of movies with 120 length and less than that

So,

No.\ of\ movies\ 120\ min\ long\ or\ less\ than\ that = 5+10+30+55\\=100\ movies

The movies of 120 min or less than 120 mins are 100
