Which direction will the box move in the diagram below?


A.It will move to the left.
B.It will move to the right.
C.It will not move.
D.It will move up.

Answers

Answer:

B.it will move to the right.

Answer: B) It will move to the right

Explanation:

We have 5 newtons of force pushing to the right, and 3 newtons of force pushing to the left. We can place the positive direction on the right hand side and the negative direction on the left.

This means we can think of "3 newtons of force to the left" as the integer -3

That way we can then add 5 to -3 getting 5+(-3) = 2. The result is positive, meaning the net force is pushing to the right. Specifically, 2 newtons of force are pushing to the right.

It's like saying there are 5 people pushing to the right and 3 pushing to the left. From each side, 3 people will pair up and they'll cancel each other out. The 2 extra people pushing right will ultimately win out.

7. Inscribed angle

Step-by-step explanation:

7. Inscribed angle

8.

y° = 70°

z° = 140°

8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.

Therefore, y° = 70°

Measure of central angle is two times the measure of the inscribed angle.

Therefore,

z° = 2* 70° = 140°

The rate of change on the graph :---

(Final amount - initial amount)/(Final year - initial year)

[tex] \frac{(0 -400)}{(9 - 0)} = \frac{-400}{9} =\boxed{-44.44}✓\\ [/tex]

slope is negative as the amount is decreasing every year

$44.44 per year is the right answer.

Miley can walk 5 1/2 miles and 1 2/3 hours how far can she walk in four hours?

Answers

Answer:

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Step-by-step explanation:

Given that:

Distance walked by Miley in [tex]1\frac{2}{3}[/tex] hours = [tex]5\frac{1}{2}[/tex] miles

We will find unit rate in term of hours.

[tex]\frac{5}{3}\ hours = \frac{11}{2}\ miles[/tex]

Multiplying both sides by 3/5

[tex]\frac{3}{5}*\frac{5}{3}\ hour = \frac{11}{2}*\frac{3}{5}\\\\Unit\ rate = \frac{33}{10}\miles\ per\ hour[/tex]

Distance walked in four hours = [tex]4*\frac{33}{10}\ miles[/tex]

Distance walked in 4 hours = [tex]\frac{66}{5}=13\frac{1}{5}\ miles[/tex]

Hence,

Miley can walk a distance of [tex]13\frac{1}{5}[/tex] miles in four hours.

Answers

Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

6x + 12 = 8x - 8

Subtract 6x from both sides.

12 = 2x - 8

Add 8 to both sides.

20 = 2x

Divide both sides by 2.

x = 10

The value of 10 for x will make the given parallelogram a rhombus.
