Answer:
Step-by-step explanation:
the perimeter of the semi-circle would be the diameter plus the circumference of half of the circle.
They want to know the perimeter of a square using the diameter of the sem-circle as ONE side, so the perimeter of the square would be 4 times the ONE side.
We should recall:
diameter = 2 times the radius circumference of a cirlce = 2π r
How do we find the diameter of the of the semi circle?
The perimeter of the semi circle is given as 108 cm
Perimeter of the semicirle = 2r + π r diameter plus semi circumference
108 = r ( 2 + π) factor out the r and solve for r
108 / (2 + π) = r divide both sides by ( 2 + r)
Now we know r, the perimeter of the squqre is 4 times 2r or 8r
perimeter of square = 8 [ 108 / (2 + π) ] π I used 3.14
= 864 / 5.14
= 168.1 cm I got rounded to nearest tenth

4x + 3 = x + 2(x + 7)
step by step
Answer:
x=11
Step-by-step explanation:
4x + 3 = x+ 2x + 14
4x + 3 = 3 x + 14
4x - 3x = 14 -3
x= 14 - 3
x= 11
Answer:
x=11
Step-by-step explanation:
Distribute :
4x + 3 = x + 2( x+ 7)
4x + 3 = x + 2x + 14
Combine like terms :
4x + 3 = x + 2x + 14
4x + 3 = 3 x+ 14
Subtract 3 from both sides of the equation :
4x + 3 = 3x + 14
4x + 3-3 = 3x + 14 -3
Simplify :
what ever way you know how to subtract the numbers you should get this answer :
4x = 3x + 11
Subtract 3 from both sides of the equation :
4x = 3x + 11
4x - 3x = 3x + 11 - 3x
Simplify :
combine like terms
multiply by 1
combine like terms
x= 11
Which set of integers is ordered from least to greatest -13 , 4, 0, -8 -5 , -2, 3, 1 -12 , -18 , -4 , 7 -15, 6 , -9 , -21
Given:
The set of integers in the options.
-13 , 4, 0, -8
-5 , -2, 3, 1
-12 -18 , -4 , 7
-15, 6 , -9 , -21
To find:
The set of integers that is ordered from least to greatest.
Solution:
We know that the larger negative value is the smaller value and the larger positive value is the greater value.
Ordered from least to greatest means first we need to write the smallest value, write the value larger than and the greatest value occurs at the end.
In option A, we have -13 , 4, 0, -8. Here, 4>0. So, the option A is incorrect.
In option B, we have -5 , -2, 3, 1. Here, 3>1. So, the option B is incorrect.
In option C, we have -12 -18 , -4 , 7 Here, -12>-18. So, the option C is incorrect.
In option D, we have -15, 6 , -9 , -21. Here, 6>-9. So, the option D is incorrect.
Therefore, all the options are incorrect.

What is the recursive formula?
Answer:
a+(n-1)d please do you get it or
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5
Step-by-step explanation:
Given the explicit formula
A(n) = 2 - 5(n - 1)
Compare with the standard form
A(n) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 5
A recursive formula allows a term in the sequence to be found by adding d to the previous term.
Then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 5 , with a₁ = 2

n =
Step-by-step explanation:
[tex]7n - 4 = 317 \\ 7n = 317 + 4 \\ 7n = 321 \\ n = \frac{321}{7} \\ n = 45 \frac{6}{7} [/tex]
Answer:
[tex]n = \frac{321}{7} [/tex]
Step-by-step explanation:
1) Add 4 to both sides.
[tex]7n = 317 + 4[/tex]
2) Simplify 317 + 4 to 321.
[tex]7n = 321[/tex]
3) Divide both sides by 7.
[tex]n = \frac{321}{7} [/tex]
Therefor, the answer is n = 321/7 and in decimal form it would be, 45.857143.

4 A triangle with a height of 3 cm and a base
of x cm is the result of reducing each
dimension by a scale factor of one-third.
The area of the original triangle is
162 cm². What was the original length of
the base?
Answer:
L = 36
Step-by-step explanation:
"A triangle with a height of 3 cm and a base of x cm is the result of reducing each dimension by a scale factor of one-third"
We are looking for the original. This triangle was reduced by 1/3, so we would have to mulitply by 3 to get the original triangle measurements.
height = 3 x 3 = 9
length = x * 3
"The area of the original triangle is 162 cm²."
Area = Base x Height/2
162 = (x*3) * 9/2
324 = (x*3)*9
36 = x*3
x = 12
What was the original length of the base?"
Length = x * 3
= 12 * 3
Length = 36

if an is defined as a geometric sequence, is the sequence 1/an also a geometric sequence? explain your reasoning.
Answer:
Since An/An-1 = r
(1/An)/(1/An-1) = An-1/An = 1/r
so, the ratio between terms is still constant.
Step-by-step explanation:
If an is defined as a geometric sequence, is the sequence 1/an also a
geometric sequence because the ratio between terms remain constant.
What is a geometric sequence and how to find its nth terms?Suppose the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r
Then the sequence would look like
[tex]a, ar, ar^2, ar^3, \cdots[/tex]
(till the terms to which it is defined)
Thus, the nth term of such sequence would be[tex]T_n = ar^{n-1}[/tex]
Since An/An-1 = r
(1/An)/(1/An-1) = An-1/An = 1/r
Therefore, the ratio between terms is still constant.
