tan∠Y = 2,14

Step-by-step explanation:

First , we need to determine XY

in order to do that we use the Pythagorean theorem :

XY = √(85^2-77^2) = 36

tan∠Y = 77/36 = 77÷36 = 2,138888888889

The planet Neptune orbits the Sun. Its orbital radius is 30.130.1 astronomical units (\text{AU})(AU).

Ronch [10]

Answer: 189.028 AU.

Step-by-step explanation:

Given: The radius of the orbit = 30.1 AU

Since, the orbit is circular in shape, then the distance traveled by Neptune is given by:-

$\text{Circumference=}2\pi r\\\\\Rightarrow\ \text{Circumference=}2(3.14)\times(30.1)\\\\\Rightarrow\ \text{Circumference=}=189.028\text{ AU}$

Hence, the distance traveled by Neptune in a single orbit around the Sun = 189.028 AU.

Solve the given inequality. Describe the solution set using the set builder or interval notation. Then graph the solution set on

Sophie [7]

Answer: THIRD OPTION.

Step-by-step explanation:

Given the following inequality:

$3(x-5)\geq 6$

You can follow these steps in order to solve it:

1. Apply Distributive property on the left side:

$3(x-5)\geq 6\\\\(3)(x)+(3)(-5)\geq 6\\\\3x-15\geq 6$

2. Add 15 to both sides of the inequality:

$3x-15+(15)\geq 6+(15)\\\\3x\geq 21$

3. Finally, divide both sides of the inequality by 3:

$\frac{3x}{3}\geq \frac{21}{3}\\\\x\geq 7$

The symbol is $\geq$ means "Greater than or equal to", and indicates that 7 is include in the solution.

Therefore, the solution can be expressed as:

$[7, \infty)$

Now you must mark this point with a closed dot on the number line and shade everything to the right.
