Answer:
The average speed of the second ant is 2 cm/s
Step-by-step explanation:
The details of the ants moving on the sides of the pentagon are;
The length of the sides of the pentagon = 12 cm
The path of the first ant = A to B, B to C, then C to D
The average speed of the first ant = 3 cm/s
The path of the second ant = A to E, and E to D
The time of arrival of the second ant at the point D = The time of arrival of the first ant at the point D
Given that both ants departed at the same time, from point A, we have;
The time it takes the first ant to arrive at the point D = The time it took the second ant to arrive at the point D
The distance from A to B = 12 cm
The distance from B to C = 12 cm
The distance from C to D = 12 cm
∴ The distance traveled by the first ant from A to D = 12 cm + 12 cm 12 cm = 36 cm
Average speed = (Total distance)/(Total Time)
Total time = (Total distance)/(Average speed)
Let 't' represent the time it takes the first ant to move from point A to point D, we have;
t = 36 cm/(3 cm/s) = 12 seconds
Therefore, the time it takes the first ant to move from point A to point D, t = 12 seconds = The time it takes the second ant to move from point A to point D through point E
The total distance traveled by the second ant from A to point E, then from point E to point D, [tex]T_{d2}[/tex] = 12 cm + 12 cm = 24 cm
The average speed of the second ant, v₂ = [tex]T_{d2}[/tex]/t
∴ v₂ = 24 cm/(12 seconds) = 2 cm/s
The average speed of the second ant, v₂ = 2 cm/s.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The solution is
(Simplify your answer.)
B. The solution is all real numbers.
OC. There is no solution.
Answer:
x = 20.
Step-by-step explanation:
37x + 16 = 6(6x + 6)
Distribute.
37x + 16 = 36x + 36
Subtract 36x from both sides.
x + 16 = 36
Subtract 16 from both sides.
x = 20.
The solution is 20.
Proof
37x + 16 = 6(6x + 6)
37(20) + 16 = 6(6(20) + 6)
740 + 16 = 6(120 + 6)
756 = 6(126)
756 = 756.

Find the missing height of the solid figure
9514 1404 393
Answer:
5 in
Step-by-step explanation:
The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.
The right side is marked as 15 inches.
The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...
10 in + ? = 15 in
? = 5 in . . . . . . subtract 10 in
The missing height is 5 inches.

Find X and arc KGH
Answer:
x = 21°
arc KGH = 228°
Step-by-step explanation:
The sum of the arcs = 360°
9x - 22° + 61° + 5x - 7° + 34° = 360°
combine like terms:
14x + 66° = 360°
subtract 66° from both sides of the equation:
14 x = 294°
x = 21°
arc KGH = 9(21°) - 22° + 61° = 228°

I need help on this question can anyone explain to me the answer?
Answer:
Option C, [tex]y = \frac{1}{10} x+1[/tex]
Step-by-step explanation:
We can find the correct answer by plugging in the x and y values of a point on the graph into each option, then finding the one that gives a true statement as a result.
For example, one point on the graph is (30,4). We can substitute 30 for the x and 4 for the y in option C's equation, [tex]y = \frac{1}{10} x+1[/tex]. Then, simplify:
[tex]y = \frac{1}{10} x+1\\4 =\frac{1}{10} (30)+1\\4 = \frac{30}{10} +1\\4 = 3 +1\\4 = 4[/tex]
4 does equal 4, so when we substitute a point from the graph into this equation, the result is a true statement. Thus, option C is the answer.
given the following sequences : -17 -25 -33 -41... write an explicit formula and find the 28th term in this sequence
Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233

now in triangle JKL
<J+<K+<L=180°[ sum of interior angles of a triangle is 180°]
49°+90°+<L=180°
<L=180°-49°-90°=41°
:.arcJK=41°
is your answer.
Answer:
Question:Find the measure of the arc or angle indicated.
Solution:In ∆LRK & ∆JKL,
∠KRL= ∠LJK = 49°
( inscribed angle standing on a same Aaka equal in a circle)Now , In ∆JKL,
∠JKL = 90°
(angle suspended to the center of the circle =90°)Now,
construction: A line segment OK joining the points O(center)& KSince, OK&OJ are the radii of the same circle,
Hence, OK = OJ
.°. ∠JKO = ∠OJK = 49°
Now,
In ∆ JOK,
∠JKO +∠OJK+ ∠JOK = 180°
Angle sum property of a∆∠JOK = 180°- (∠JKO +∠OJK)
∠JOK = 180°-(49°+49°)
∠JOK = 180°- 98°
∠JOK = 82°
Hence, 82° is your answer[tex] \\ \\ [/tex]

(4x – 10)
Find the value of x.
Answer:
x = 34
Step-by-step explanation:
4x - 10 + x + 20 = 180
5x + 10 = 180
5x = 170
x = 34
Answer:To find the value of x, we can use the property of opposite angles in a parallelogram. In a parallelogram, opposite angles are congruent.
Given that mF = x + 20° and mi = 4x - 10, we can set these two expressions equal to each other:
x + 20° = 4x - 10
Now, let's solve for x:
x - 4x = -10 - 20°
-3x = -30°
Divide both sides by -3:
x = -30° / -3
x = 10°
Therefore, the value of x is 10°.

If a triangle is rotated about the y-axis as shown below, what three-dimensional polyhedral would be formed?
An image of a right triangle centered at the origin is shown with an arrow showing motion about the y axis.
(1 point)
Triangular prism
Cone
Cylinder
Square pyramid
Answer:
Cone
Step-by-step explanation:
I took the test and got it right :)
The triangle is rotated about the y-axis then a cone will be formed.
It is given that the triangle is rotated about the y-axis as shown in the picture.
It is required to find what three-dimensional polyhedral would be formed.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have an image of a right triangle centered at the origin in the picture, if we rotate it about the y-axis we will get a cone because the side which is at the y-axis will be fixed and the base of the triangle will move about the y-axis which will make a circular shape similarly the other side(hypotenuse) will also rotate about the y-axis which will create an outer surface for the cone.
Thus, the triangle is rotated about the y-axis then a cone will be formed.
