Please check the explanation.
Step-by-step explanation:
1) Writing the equation of the pattern
Figure 1 has 4 circles.
Figure 2 has 7 circles.
Figure 3 has 10 circles.
Thus, the sequence becomes
4, 7, 10,...
Finding the common difference between the adjacent terms
d = 7 - 4 = 3, d = 10 - 7 = 3
As the common difference is the same, so this represents the Arithmetic sequence.
so
d = 3
as
a₁ = 4
Thus, the nth term of the Arithmetic sequnce is
aₙ = a₁ + (n-1)d
aₙ = 4 + (n-1)3
aₙ = 4 + 3n - 3
aₙ = 1 + 3n
2) Determining the circles in the 23rd figure
As the nth term is given by
aₙ = 1 + 3n
putting n = 23
a₂₃ = 1 + 3(23)
a₂₃ = 1 + 69
a₂₃ = 70
3) Determining the figure having 82 circles
As the nth term is given by
aₙ = 1 + 3n
Given
aₙ = 82
To determine
n=?
Thus,
aₙ = 1 + 3n
82 = 1 + 3n
3n = 82-1
3n = 81
Dividing both sides by 3
n = 27
Therefore, 27th figure will have 82 circles.

Are these triangles congruent? If so, state why. Choose the correct answer.
Answer: C) The triangles are not congruent
======================================================
Explanation:
At first glance, they seem to be congruent. However, we simply don't have enough information to say yes or no.
Note how VT = VT by the reflexive theorem. This is the shared overlapping sides.
The tickmarks indicate WT = VU is another pair of congruent sides.
Finally, the red arcs indicate angles TWV and VUT are congruent.
We have two pairs of congruent sides and a pair of congruent angles; however, the angles are not between the congruent sides. Recall that SSA is not a valid congruence theorem. This is because SSA could lead to ambiguity.
So that's why we don't have enough info to say if they are congruent or not. That's why choice C is the best answer.

Step-by-step explanation:
Make a reasonable estimate for the situation. A snail moves at a speed of 3.395 inches per minute. If the snail keeps moving at this rate, about how many inches will it travel in 6.187 minutes?
Answer:
Distance = 21.0049 inches
Step-by-step explanation:
Given the following data;
Speed = 3.395 inches per minute.
Time = 6.187 minutes
To find the distance;
Distance = speed * time
Substituting into the equation, we have;
Distance = 3.395 * 6.187
Distance = 21.0049
The vertices of a polygon are given. Find the coordinates of the vertices of the image after the specified translation.
P(–5, 4), Q(1, 4), R(1, 1);
(x, y) —--> (x + 1, y – 5)
P’ (__, __) Q’ (__,__) R’ (__,__)
Answer:
The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)
Step-by-step explanation:
If the point (x, y) is translated horizontally h units and vertically k units, then its image is (x + h, y + k) and the rule of translation is T (x + h, y + k)
∵ The vertices of the polygons are P (-5, 4), Q (1, 4), R (1, 1)
∵ The rule of translation is (x, y) → (x + 1, y - 5)
→ That means add each x-coordinate by 1 and subtract each
y-coordinate by 5
∴ P' = (-5 + 1, 4 - 5)
∴ P' = (-4, -1)
∴ Q' = (1 + 1, 4 - 5)
∴ Q' = (2, -1)
∴ R' = (1 + 1, 1 - 5)
∴ R' = (2, -4)
∴ The coordinates of the images are P' (-4, -1), Q' (2, -1), R' (2, -4)

A cell phone plan costs 28.70$ per month for minutes of talk time. It costs an additional $0.05 per minute for each minute over 700 minutes. To get e-mail access, it costs 30% of the price for 700 minutes of talk time. Your bill, which includes e-mail, is the same each month for months. The total cost for all months is $326.48. Write and solve an equation to find the number of minutes of talk time you use each month.
Answer:
Total number of minutes= 6,483
Step-by-step explanation:
Giving the following information:
Fixed cost (700 minutes)= $28.7
E-mail= (28.7*0.3)= $8.61
Cost per minute (over 700)= $0.05
Total cost= $326.48
First, we establish the total cost formula:
Total cost= 28.7 + 8.61 + 0.05*x
x= number of minutes over 700
Now, we need to calculate the number of minutes over 700:
326.48= 28.7 + 8.61 + 0.05x
289.17=0.05x
5,783 = x
Total number of minutes= 700 + 5,783
Total number of minutes= 6,483
A 30ft electric line is suspended between the tops of two 20ft electric poles on level ground. The lowest point of the line is 5ft above the ground. What's the distance between the two electric poles?
Answer:
There is no distance between them
Step-by-step explanation:
For a 30 ft electric line to be placed between two 20ft electric poles, it would take 15 ft of the electric line to go down to about 5 ft above the ground and another 15 ft of the line to go to the top of the second electric pole. This means that a total of 30ft (15 ft + 15 ft) electric line would be needed which is all the cable we have.
For this to be possible then the poles must be adjacent to each other (i.e. no distance between them).

#surfacearea
Answer:
773 or 278.5 (if it only wants the sides the pic shows)
Step-by-step explanation:
13*5=65
65/2=32.5 (since it is a triangle you by 2)
12*9=108
108/2=54
15*20=300 (it is a square so you leave it)
you do it on the other sides that you can't see in the pic.
Add all the numbers together: 32.5+32.5+54+54+300+300 or 32.5(2)+56(2)+300(2)=773

Step-by-step explanation:
The length of the second side of a triangle is twice the length of the first side. The length of the third side is 4 units more than the first side. The perimeter of the triangle is 52 units. How long is each side, and how do you determine that?
Answer:
First side = 12 units
Second side = 24 units
Third side = 16 units
Step-by-step explanation:
First, we can assign variables for each side of the triangle to make it easier:
A = side 1
B = side 2
C = side 3
The length of the second side of the triangle is twice the length of the first side, so we know that B is twice the length of A. We can represent this in an equation like this:
B = A * 2
The length of the third side is 4 units more than the first side. This tells us that C is going to be 4 more than A:
C = A + 4
And finally, the perimeter of the triangle is 52 units. Since the perimeter is just all the sides added together, we can create this equation:
A + B + C = 52
To start solving for lengths, I'm going to plug in the first two equations we got into the third equation:
A + B + C = 52
A + (A * 2) + (A + 4) = 52
1A + 2A + 1A + 4 = 52
4A + 4 = 52
4A = 48
A = 12
Now that we know what A is, we can solve for the other two variables:
B = A * 2
B = 12 * 2
B = 24
C = A + 4
C = 12 + 4
C = 16
Now we have all three variables, just don't forget what the variables represent (first side, second side, third side).

It is given that set W = { x, y, z).
What is the subset of set W?
Answer:
Please check the explanation.
Step-by-step explanation:
Given the set W = {x, y, z}
If there are n elements in a set, then are 2ⁿ subsets.
As there are 3 elements in a set, then are 2³ or 8 subsets.
so
W = {x, y, z} has 8 subsets.
They are:
∅, {x}, {y}, {x}, {x, y}, {x, z}, {y, z}, and {x, y, z}
Please note that any subset of the set W = {x, y, z} contains all the elements which are also the elements of the set W = {x, y, z}Please answer question... if it is good will give brainliest
^2 = SQUARED( to the second power)
Answer:
2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.
Step-by-step explanation:
2. 2x * 2x = 4x^2
+i * -i = -i^2
-i^2 can be transferred into positive 1.
i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.
3. The same thing as 2.^
1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.
