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°

A rectangular field is five times as long as wide. If the perimeter of the field is 780 feet, what are the dimensions of the field?
Answer:
65 and 325
Step-by-step explanation:
(l+w)*2 = 780
l+w = 390
l = 5w
5w + w = 390
6w = 390
w = 65
length = 325

A particular plant root grows 2.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters).
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.
2. 5 inches * 2.54 cm/1 inch
inches cancels out and now you are left with multiplying 2.5 and 2.54.
2.5 * 2.54 cm = 6.35 cm
If I was to sketch the graph of y=4x+2
What would the graph look like?
Would it be a straight line or a curved line?
Where would it cross the y-axis?
What does 4 in 4x tell us?
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x + 2 ← is in slope- intercept form
Thus its graph is a straight line
crosses the y- axis at (0, 2 ) , that is c = 2
the 4 in 4x is the slope m of the line

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
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.

O is the centre of the circle.
Determine the value of a°.
Answer:
m<a=41º
Step-by-step explanation:
a triangle has 180º total
180-98=82
since O is the center that makes OQ and OP radii and as such they are equally distanced
this means that the m<a and the measure opposite it are equal
so ÷82 by 2

Find the value of x.
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/2 -5=20 please give details
Answer: x=50
how?
[tex]\frac{x}{2}[/tex] - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:
[tex]\frac{x}{2}[/tex]=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)
25 x 2= 50
therefor the x=50
