Answer:

YES, YES, NO, YES

Step-by-step explanation:

Cos angle = adj/hyp

Sin angle = oppo/hyp

Tan angle = oppo/adj

Sin B = AC /13.

AC = 13 sin B. This YES

Cos A = AC/13

AC = 13 cos A. This YES

Tan A = 12/AC

AC = 12/ tan A. This is NO

Tan B = AC /12

AC = 12 tan B. This is YES

<h2>Answer:</h2><h2>The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %</h2>

Step-by-step explanation:

Let the fraction be represented as \frac{x}{y} where x is the numerator and y is the denominator

Given that numerator will increase by 25 %, = 25% x

   = 0.25 x

Given that denominator will increase by 20 %, = 20% y

   = 0.2 y

The new fraction becomes  = \frac{x + 0.25 x}{y + 0.2 y}

= \frac{1.25 x}{1.2 y}

= (\frac{1.25}{1.2} ) \frac{x}{y}

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %

4) 4x + 3y = 56<br> 2x + y = 24<br> Solve using elimination please show work
lesya [120]

Answer:

x = 8     y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now  4x + 3y = 56

         <u>-6x - 3y = -72</u>

         -2x      =  -16

            x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check:  Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56  So we have the correct values for x and y
