Answer:

$\large\boxed{x=\dfrac{1}{2}=0.5}$

Step-by-step explanation:

$\dfrac{5}{6x}=\dfrac{10}{3}\qquad\text{cross multiply}\\\\(6x)(10)=(5)(6)\\\\60x=30\qquad\text{divide both sides by 60}\\\\x=\dfrac{30}{60}\\\\x=\dfrac{1}{2}$

wel

Answer:

Step-by-step explanation:

The lights and pole form a right triangle. The question gives the hypotenuse as 5 and one side length as 4.

Use the Pythagorean theorem: $a^2+b^2=c^2$ .

Plug in what you are given: $4^2+b^2=5^2$

$16+b^2=25$

$b^2=9$

b = 3

Or you could recognize that it was a pythagorean triple: 3, 4, 5

Distance Formula D=√(x2-x1)² + (y2 - y₁) ² a. 8.149 b. 8.84 c. 9.438 d.12.369

lakkis [162]

Answer:

Step-by-step explanation:

using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )

d = $\sqrt{10-(-2))^2+(1-4)^2}$

= $\sqrt{(10+2)^2+(-3)^2}$

= $\sqrt{12^2+9}$

= $\sqrt{144+9}$

= $\sqrt{153}$

≈ 12.369
