Answer:

-22

Step-by-step explanation:

PEMDAS!

Solve (15 ÷ 5 × 6) first. This is equal to 18.

$3^2$ + 18 - 49

$3^2$ is equal to 9.

9 + 18 - 49 = -22

Divide x^3/4 over x^1/6

kvv77 [185]

Answer:

Step-by-step explanation:

$\frac{x^{\frac{3}{4} } }{x^{\frac{1}{6} } } = x^{\frac{3}{4} - \frac{1}{6} \\$

$\frac{3}{4} - \frac{1}{6} = \frac{(3 * 6) - (4 * 1)}{(4 * 6)}$

$\frac{18 - 4}{24} = \frac{14}{24} = \frac{7}{12}$

irakobra [83]

Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos30° = $\frac{\sqrt{3} }{2}$ , then

cos30° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{20}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2x = 20 $\sqrt{3}$ ( divide both sides by 2 )

x = 10 $\sqrt{3}$ → B
