Answer:

-15 and 9

Step-by-step explanation:

$x^2+6x=135 \\\\\\x^2+6x-135=0 \\\\\\x=\dfrac{-6\pm\sqrt{36+540}}{2}=\dfrac{-6\pm\sqrt{576}}{2}=\dfrac{-6\pm24}{2}=-3\pm12=-15,9$

Hope this helps!

If 5/12 visitors are adults and 3/10 were men what fraction were men?

Zigmanuir [339]

You need to do the following equation:

(5/12)*(3/10)

5*3=15

12*10=120

15/120=5/40 of the adults who visited were men.

Give the exact form and decimal form of the equation

Svet_ta [14]

Answer:

Exact form: $\sin{(6x)} = \frac{8}{9}$

Decimal form: $\sin{(6x)} = 0.8889$

The solution for x is: The solution for x is of 10.455º

Step-by-step explanation:

We are given the following equation:

$8 = 9\sin{(6x)}$

Placing into the desired format, the exact format is:

$\sin{(6x)} = \frac{8}{9}$

In the decimal part, we divide 8 by 9. So

$\sin{(6x)} = 0.8889$

Solving for x:

We apply the inverse sine. So

$\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}$

$6x = 62.73$

$x = \frac{62.73}{6}$

$x = 10.455$

The solution for x is of 10.455º

Eva has $10 for lunch. Her meal cost $8.60. She wants to leave a 20% tip. Does she have enough money? Explain your reasoning.

snow_tiger [21]

No she doesn't have enough money. All you do is multiply 8.60 by .2 which come out to 1.72 and 8.60 plus 1.73 which equals 10.33 so she needs 33 more cents tone able to tip 20%.
