Mollie watches a film that lasts 130 min it begins at 6:15 pm. What time did it end?
Natalka [10]
Answer:

Starts at 6:15

Note: An hour is 60 minutes.

So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.

So the film ended at 8:25.

What is the value of y? NU=9, NM= 3, MT= 6, TN= y
nevsk [136]

Answer:

6\sqrt{3}

Step-by-step explanation:

We have to use Pythagoras' identity twice to find y

The square on the hypotenuse is equal to the sum of the squares on the other two sides.

In right triangle MUT to find TU

TU² + 3² = 6², that is

TU² + 9 = 36 ( subtract 9 from both sides )

TU = 27 ( take the square root of both sides )

TU = \sqrt{27} = \sqrt{9(3)} = 3\sqrt{3}

In right triangle NUT to find y

y² = 9² + (3\sqrt{3} )² = 81 + 27 = 108 ( take the square root of both sides )

y = \sqrt{108} = \sqrt{36(3)} = 6\sqrt{3}

Could any of you help explain this to me? please and thank youuu
Zanzabum
Variables: x, y, z (we should multiply them and put them together )
x \times y \times z = xyz
Then coeffitions, we should multiply them
3 \times 5 \times 7 = 105
Now put coeffitions before variables:
105 \times xyz = 105xyz
