The least common multiple of 30 and 13 is 390 !

**Answer:**

**51°**

**Step-by-step explanation:**

Note that the square in the angle place = 90°.

Also note, that a complete circle is 360°.

Set the equation. Let the ? be denoted by the variable x:

x + 90+ 124 + 95 = 360

Simplify. Combine like terms:

x + (90 + 124 + 95) = 360

x + (309) = 360

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:

x + 309 (-309) = 360 (-309)

x = 360 - 309

x = 51

**51°** is your answer.

**Answer:**

Thus # 2 is correct **(5 (y + 4))/2**

**Step-by-step explanation:**

Simplify the following:

(5 y (y^2 - 16))/(2 y (y - 4))

(5 y (y^2 - 16))/(2 y (y - 4)) = y/y×(5 (y^2 - 16))/(2 (y - 4)) = (5 (y^2 - 16))/(2 (y - 4)):

(5 (y^2 - 16))/(2 (y - 4))

y^2 - 16 = y^2 - 4^2:

(5 (y^2 - 4^2))/(2 (y - 4))

Factor the difference of two squares. y^2 - 4^2 = (y - 4) (y + 4):

(5 (y - 4) (y + 4))/(2 (y - 4))

Cancel terms. (5 (y - 4) (y + 4))/(2 (y - 4)) = (5 (y + 4))/2:

Answer: (5 (y + 4))/2

**Answer:**

The correct answer is C. She could use a six-sided number cube.

**Step-by-step explanation:**

Since Shiloh has 6 options from which to choose a unique alternative, it can be stated that her eligibility ratio is 1/6. Thus, since the dice has 6 numbers and only 1 will come up face up, the option of the dice is the most appropriate to make her decision.

On the other hand, the other options do not contemplate 6 possibilities but 12, 2, 12 and 13 possibilities respectively, with different possible alternatives, which does not give an equitable distribution of possibilities between each option.
