1/3 and 1.5

Step-by-step explanation:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15

There are 5 Multiples of 3 on the Spinner and 3 multiples of four.

5/15 is the probability for a multiple of 3 which can be simplified to 1/3

3/15 is the probability for a multiple of 4 which can be simplified to 1/5

Hope this Helps!

Solve x2 + 10x = 24 by completing the square. Which is the solution set of the equation? (negative 5 minus StartRoot 34 EndRoot

Naya [18.7K]

Answer:

x = - 12, x = 2

Step-by-step explanation:

Given

x² + 10x = 24

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = 24 + 25

(x + 5)² = 49 ( take the square root of both sides )

x + 5 = ± $\sqrt{49}$ = ± 7 ( subtract 5 from both sides )

x = - 5 ± 7, thus

x = - 5 - 7 = - 12 or x = - 5 + 7 = 2

Answer:

skew

Step-by-step explanation:

Perpendicular lines must intersect. In fact, they intersect forming right angles.

Lines AC and RC are not in the same plane and do not intersect.

They are called "skew lines."

Find the measure of the exterior angle.

MaRussiya [10]

Answer:

$120 \degree$

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle

Therefore,

$90 + x = 4x$

Now solve for x

$90 + x = 4x \\ 90 = 4x - x \\ 90 = 3x \\ \frac{90}{3} = \frac{3x}{3} \\ 30 \degree = x$

Now let's solve for the exterior angle

$4x \\ 4 \times 30 \\ 120 \degree$

Hope this helps you.

Let me know if you have any other questions :-)
