Answer:

\huge\boxed{\sf \frac{1}{12} }

Step-by-step explanation:

<u>Ratio of 45 minutes to 9 hours:</u>

<u>45 mins : 9 hours      [1 hour = 60 mins</u>]

45 mins : 9 * 60 mins

45 mins : 540 mins

45 : 540

÷5    ÷5

9 : 108

÷3   ÷3

3 : 36

÷3  ÷3

1 : 12

<u>It can also be written as:</u>

= \sf \frac{1}{12}

\rule[225]{225}{2}

Hope this helped!

Parallelogram pqrs is shown angle s is (3x)° angle r is 120° and angle q is (2y)° find the value of y
Arada [10]
Parallelograms have adjacent angles supplementary (sum to 180).
For pair r and s, 
3x+120=180, => x=(180-120)/3=20 &deg; 
Similarly, for pair q and r,
2y+120=180 => y=(180-120)/2 = 30 &deg;

Answer:

64.025°F

I think I did it right

Step-by-step explanation:

65=100%

65/100=0.65

0.65=1%

3%=1.95

4.5%=2.925

65+1.95=66.95

66.95-2.925=64.025

Nonsense will be reported!!​
Ainat [17]

[8] The hypotenuses must be congruent, DE and IJ

     HL is hypotenuse-leg, or where the hypotenuse and one leg are congruent.

     Since we see a leg is congruent, to prove they are congruent with HL we will need to know that the hypotenuses are congruent.

[9] Another leg, AC and YX

     LL is leg-leg. Since we have one leg, we will need the other leg to prove the triangles are congruent by LL.

[10] A leg, DE and E? or FE and E?

     LA means leg-angle. The angles by point E are vertical angles, so they will be congruent. To finish prooving the congruence using LA we will also need a leg.

-> The question marks are because the letters are too blurry to read.
