None of the above
Answer: It is the None of them. If you see, one of the lines is Dotted, and one is solid. So, the Solid has either has ≤ or ≥ in it's equation. If the second option, and in the second option, the second equation has one of those signs, it would be correct, but it doesn't, so it's none of the above. I hope this didn't confuse you, and Happy Holidays! :)

Answer:
# of sides [tex]{}[/tex] Interior One Interior Angle Exterior One
[tex]{}[/tex] Angle Sum Angle Sum Exterior Angle
14 [tex]{}[/tex] 2,160° 154.3° 360° 25.714°

30 [tex]{}[/tex] 5,040 168° 360° 12°
12 [tex]{}[/tex] 1,800 150° 360° 30°
Step-by-step explanation:
Please find attached the table of values calculated with Microsoft Excel
From the given table, we have the formula for the following parameters;
Number of sides = n
Interior Angle Sum = 180×(n - 2)
Measure of ONE Interior = 180×(n - 2)/n
Angle (regular polygon)
Exterior Angle Sum = 360°
Measure of ONE Exterior = 360°/n
Angle (regular polygon)
1) When n = 14, we have;
The interior Angle Sum = 180×(14 - 2) = 2,160°
The measure of one Interior angle (regular polygon) ; 180×(14 - 2)/14 ≈ 154.3°
The exterior angle sum = 360°
The measure of one exterior angle (regular polygon) = 360°/14 ≈ 25.714°
2) When n = 24, we have;
The interior Angle Sum = 180×(24 - 2) = 3,960°
The measure of one interior angle (regular polygon); 180×(24 - 2)/24 = 165°
The exterior angle sum = 360°
The measure of one exterior angle (regular polygon) = 360°/24 = 15°
3) When the interior angle sum = 180×(n - 2) = 1,080°, we have;
n = 1,080°/180° + 2 = 8
n = 8
The measure of one interior angle (regular polygon); 180×(8 - 2)/8 = 135°
The exterior angle sum = 360°
The measure of one exterior angle (regular polygon) = 360°/8 = 45°
4) When the interior angle sum = 180×(n - 2) = 5,040°
n = 5,040°/180° + 2 = 30
n = 30
The measure of one interior angle (regular polygon); 180×(30 - 2)/30 = 168°
The exterior angle sum = 360°
The measure of one exterior angle (regular polygon) = 360°/30 = 12°
5) When the measure of one interior angle (regular polygon), 180×(n - 2)/n = 150°, we have;
180°·n - 2×180° - 150°·n = 0
30°·n = 360°
n = 360°/30° = 12
n = 12
The exterior angle sum = 360°
The measure of one exterior angle (regular polygon) = 360°/12 = 30°

Find the
measure of X given two triangles:
Answer:
The measure of angle x is 68°
Step-by-step explanation:
The isosceles triangle has two sides equal, the angle between these two sides is called the vertex angle, the other two angles are called the base angles and they are equal in measures
In the given figure
∵ An isosceles Δ has a vertex angle of measure 68°
∴ The other two angles are equal in measure ⇒ base angles
→ The sum of the measures of the interior angles of a triangle is 180°
∴ The sum of the measures of the base angles = 180° - 68°
∴ The sum of the measures of the base angles = 112°
→ Divide their sum by 2 to find the measure of each angle
∵ The measure of each base angle = 112° ÷ 2
∴ The measure of each base angle = 56°
∵ There are two intersected segments
∴ There is a pair of vertically opposite angles
∵ The other isosceles Δ has a vertex angle of measure x
∵ A base angle of the 1st Δ and a base angle of the 2nd Δ are vertically
opposite angles
∴ They are equal in measure
∴ The measure of the base angle of the 2nd Δ = 56°
∴ The two base angles are equal in measure
∴ The measure of each base angle is 56°
→ The sum of the measures of the interior angles of a triangle is 180°
∵ 56° + 56° + x = 180°
∴ 112° + x = 180°
→ Subtract 112 from both sides
∴ x = 68
∴ The measure of angle x is 68°

Answer:
14/8 = 1 3/4
48/9 = 5 1/3
Step-by-step explanation:
14/8 = 1 6/8
6/8 = 3/4
14/8 = 1 3/4
48/9 = 5 3/9
3/9 = 1/3
48/9 = 5 1/3

A question on a test asks students to find the speed at which a car travels. The graph shows a proportional relationship between the distance traveled in miles and time in hours. billy incorrectly says that the speed of the car is 1/62
mile per hour. What is the speed of the car? What error might billy have made?
Answer: For time t ≥ 0 hours, let r(t) = 120 1 − e−10t2 represent the speed, in kilometers per hour, at which a ()
car travels along a straight road. The number of liters of gasoline used by the car to travel x kilometers is −x 2
modeled by g(x) = 0.05x 1 − e . ()
(a) How many kilometers does the car travel during the first 2 hours?
(b) Find the rate of change with respect to time of the number of liters of gasoline used by the car when
t = 2 hours. Indicate units of measure.
(c) How many liters of gasoline have been used by the car when it reaches a speed of 80 kilometers per
(a)
(b)
hour?
∫ 2 r (t ) dt = 206.370 kilometers 0
dg dg dx dx dt=dx⋅dt; dt=r(t)
2 : {1 : integral 1 : answer
3:{2:useschainrule
1 : answer with units
dg dt
t=2
dg
= dx ⋅r(2)
x=206.370
= (0.050)(120) = 6 liters hour
(c)
Let T be the time at which the car’s speed reaches 80 kilometers per hour.
Then, r(T ) = 80 or T = 0.331453 hours. At time T, the car has gone
x(T ) = ∫ T r (t ) dt = 10.794097 kilometers 0
and has consumed g(x(T )) = 0.537 liters of gasoline.

Enter your answer by filling in the boxes to complete the equations that describe the calculation.
80 ÷ 5 = __ ÷ 5 + __ ÷ 5
= __ + 6
= __
Answer:
80 / 5 = 40 / 5 + 40 / 5 = 10 + 6 = 16
Step-by-step explanation:
80 / 5 = 16
__ / 5 + __ / 5
You can do 80 / 2 to fill in those two blanks because the answer needs to equal the same as 80 / 5
80 / 2 = 40
40 / 5 + 40 / 5
8 + 8 = 16
the third blank needs to also equal 16. So you can do 16 - 6 to know what fills in the blank.
16-6
10
10+6 = 16
The last blank must equal the same as all the other equations so 16 would fill it.
If you need further help, don't be afraid to reach out with any questions. I hope this helps!
Answer:
80/5= 50/5 + 30/5= 10 + 6= 16
What expression is equivalent to (2a - 7) + 5(3 - a)
Answer:
Step-by-step explanation:
2a-7+15-5a
2a-5a-7+15
-3a+8
The expression which is equivalent to (2a - 7) + 5(3 - a) would be; -3a+8
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We have been given an expression as;
(2a - 7) + 5(3 - a)
Therefore, solving it further;
2a-7+15-5a
Combine the like terms;
2a-5a-7+15
Then we get;
-3a+8
Hence, the expression which is equivalent to (2a - 7) + 5(3 - a) would be; -3a+8
