Geometry help please. What is the value of v?

Answers

Answer:

v=15

Step-by-step explanation:

31+4v+44=9v

Answer:

v = 15

Step-by-step explanation:

By exterior angle theorem:

9v° = 31° + (4v + 44)°

9v° = (4v + 44 + 31)°

9v = 4v + 75

9v - 4v = 75

5v = 75

v = 75/5

v = 15

Step-by-step explanation:

1/3 is 0.3333333 so 0.3333333 + 5 is 5.333333

Answer:

1/3 + 5 = 16/3 or 5 1/3

Step-by-step explanation:

First we convert 5 to a equal fraction towards 1/3.

5 = 5/1 = 15/3

Then we add 15/3 and 1/3.

15/3 + 1/3 = 16/3.

16/3 = 5 1/3.

So, the answer is 16/3 or 5 1/3.

What is the distance between the two coordinates points c and b?

Answers

I believe the answer is 2 if that’s an option

I need help on listing the four points that have a distance of 8 from B, thank you!

Answers

Answers:

(12, 3)(-4, 3)(4, 11)(4, -5)

A diagram is shown below.

===========================================================

Explanation:

First we locate point B at (4,3). The '4' in the x position means we've gone 4 units to the right of the origin, and the 3 in the y coordinate means we've gone 3 units up.

Now we need to find four points that are 8 units away from this central location. We'll ignore point A.

What we can do is add 8 to the x coordinate of point B to get x+8 = 4+8 = 12. Keeping the y coordinate the same, the point (12, 3) is exactly 8 units away from (4,3). Think of drawing a number line through those two points. Then we can note there are 8 spaces between (4,3) and (12,3). Or we can say "there are 8 spaces between 4 and 12" since that '3' doesn't really play much of a role in this case.

So (12,3) is one answer.

---------------------------------

Move back to point B(4,3)

Instead of adding 8 to the x coordinate, let's subtract 8 from it

x-8 = 4-8 = -4

Again the y coordinate is kept the same.

The point (-4, 3) is 8 units away from (4,3). The number line distance from -4 to 4 is 8 units.

So (-4,3) is another answer.

----------------------------------

Move back to point B

From this starting point, we can move 8 units up. Doing this means we add 8 to the y coordinate, while the x coordinate is kept intact.

(4,3) turns into (4,11) after doing so.

(4,11) is another answer.

---------------------------------

Move back to point B

From this point, we can move down 8 units to arrive at (4,-5). note how y-8 = 3-8 = -5. The x coordinate is kept the same.

(4,-5) is another answer.

----------------------------------

The four points we found were:

(12, 3)(-4, 3)(4, 11)(4, -5)

which are four possible answers

Those points are found by going 8 units right, 8 units left, 8 units up and 8 units down in that order. Each time we started at point B as our center of operation. The use of the word "center" is done because we can form a circle of radius 8, and the center of the circle is at B(4,3). Any point on the circle's edge is exactly 8 units away from the center point B.

Refer to the diagram below. The four answers are the red points P,Q,R,S. The point T is another point that could be an answer, but it's not as easy to find compared to the four other points.

[tex](-27)^\dfrac{2}{3}[/tex] = 9

Step-by-step explanation:

Given that,

Asn expression : [tex](-27)^\dfrac{2}{3}[/tex]

We need to evaluate the above expression.

We know that, [tex](-3)^3=-27[/tex]

So,

[tex](-27)^\dfrac{2}{3}=(-3)^{3\times \dfrac{2}{3}}[/tex]

or

[tex]=(-3)^2\\\\=-3\times -3\\\\=9[/tex]

So, the value of [tex](-27)^\dfrac{2}{3}[/tex] is 9. Hence, the correct option is (b).
