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).

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)

Answer:
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.

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).

find the surface area of the cylinder using pie.
Answer:
≈1130.97336 yd
Step-by-step explanation:
the formula to find the surface is A= 2 π r h + 2 π r 2
where r is the radius and h the height. you subsitute it with your value.
r = 9 yd and h = 11 yd
so, A= 2 π r h + 2 π r 2 = 2 x π x 9 x 11 + 2 x π x 9^2 ≈ 1130.97336 yd

Solving systems of equation using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x = y + 2
3x + 2y = 5
Step 2: Rewrite Systems
3x = y + 2
Subtract 2 on both sides: 3x - 2 = yRewrite: y = 3x - 2Step 3: Redefine Systems
y = 3x - 2
3x + 2y = 5
Step 4: Solve for x
Substitution
Substitute in y: 3x + 2(3x - 2) = 5Distribute 2: 3x + 6x - 4 = 5Combine like terms: 9x - 4 = 5Isolate x term: 9x = 9Isolate x: x = 1Step 5: Solve for y
Define equation: 3x + 2y = 5Substitute in x: 3(1) + 2y = 5Multiply: 3 + 2y = 5Isolate y term: 2y = 2Isolate y: y = 1Use the graph below for this question: A 6 4 3 What is the average rate of change from x = -1 to x = -2? (1 point) 2 - 2 4 -1
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change = [tex]\frac{5-7}{-1-(-2)}[/tex] = [tex]\frac{-2}{1}[/tex] = - 2
