Answer:

The plant root is growing 6.35 cm per month.

Step-by-step explanation:

This is a conversion problem. You are converting 2.5 inches to centimeters.

hope this helps you.

Answer:

2x° + 10° = 90°

3x° = 120°

2x° + 5° = 85°

2x° - 15° = 65°

Step-by-step explanation:

360° = 3x° + 2x° + 5° + 2x° + 10° + 2x° - 15°

360° = 3x° + 2x° + 2x° + 2x° + 5° + 10° - 15°

360° = 9x°

9x° = 360°

x° = 360° : 9

x° = 40°

2x° + 10°

= 2(40°) + 10°

= 80° + 10°

= 90°

3x°

= 3(40°)

= 120°

2x° + 5°

= 2(40°) + 5°

= 80° + 5°

= 85°

2x° - 15°

= 2(40°) - 15°

= 80° - 15°

= 65°

4. Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the
week beforeThis is a result of...
Sunk cost

Overconfidence

Endowment effect

Answers

Answer:

Endowment effect

Step-by-step explanation:

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

This is a result of the endowment effect.

Given,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

We need to find whether it is a result of

- Sunk cost

- Overconfidence

- Endowment effect

What are the endowment effect and Sunk cost?

The endowment effect is the effect of placing a higher value on an object

they own than the value on the same object they did not own.

The sunk cost is a cost that has already been incurred and that cannot be

recovered.

We have,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

Here,

We are talking about the same item $20.

Losing $20 is losing what Michael owns.

Finding $20 on the sidewalk is not what Michael owns.

And the pain of losing $20 which he owns is more than the joy of finding it on the sidewalk so,

The Endowment effect is found here.

Thus,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

This is a result of the endowment effect.

X would be “C. 14”.

By the vertical angle theorem, the 60 and the 5x - 10 are congruent and equal. Put them equal to each other and solve for x. You end up with X = 14

Find the value of x.

Answers

Step-by-step explanation:

the sum of all angles in a triangle is always 180 degrees.

so,

x + 12 + 2x - 29 + x + 5 = 180

4x - 12 = 180

4x = 192

x = 48

X+12+2x-29+x+5 = 180. This is because a triangle has 180 degrees
Simplify
4x-12=180
Add 12 to both sides
4x = 192
Divide both sides by 4
X=48
