Answer:
a(n) = 27*(2/3)^(n - 1)
Step-by-step explanation:
The first four terms are 27, 18, 12, 8.
Find the common ratio:
To do this, let that ratio = r, and write and solve 27r = 18. Thus, r = 2/3.
The general explicit formula for this sequence is
a(n) = a(1)*(2/3)^(n - 1), or, since a(1) = 27, a(n) = 27*(2/3)^(n - 1)
111 is 15% of what number
Answer:
16.65
Step-by-step explanation:
15 percent of 111 is the same as 15 per hundred of 111. We can therefore make the following equation:
15/100 = X/111
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 111, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
15/100 = X/111
X/111 = 15/100
X*111/111 = 15*111/100
X = 1665/100
X = 16.65
or
The work above shows the long way to explain how to calculate 15 percent of 111 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 15 percent of 111?", Y is 111 and P is 15:
(111 * 15)/100 = 16.65
And once again you see that the answer is 16.65.
Answer:
740
Step-by-step explanation:
If we substitute "what number" in the question "111 is 15 percent of what number?" with 740, we get this sentence: 111 is 15 percent of 740. Since this statement is true, we know that our answer is correct.
Following shows the steps on how to derive this formula
Step 1: If 15% of a number is 111, then what is 100% of that number? Setup the equation.
111 Y
------ = -------
15 100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
15Y = 111 x 100
15Y = 11100
Y = 11100
100 = 740
Formula = Number x 100 111 x 100
--------------------- = ------------ = 740
Percent 15

A. Definition of Congruence
B. Angle Addition Postulate
C. Supplement Theorem
D. Definition of Vertical Angles
The correct reason for the statement ∠1 ≅ ∠2 will be;
⇒ Definition of Vertical Angles.
Option D is true.
What is Vertical angles?
When the two lines are crosses to each other at a point then the vertical angles are formed.
Given that;
∠1 and ∠2 are formed between two lines which crosses at a point.
Now,
The two lines are vertical lines which passes through a point and ∠1 and ∠2 are formed between them.
So, By definition of Vertical Angles;
∠1 ≅ ∠2
Therefore,
The correct reason for the statement ∠1 ≅ ∠2 will be;

x=12
q=10.12+13
123
Answer:
P = 25
Q = 133
R = 22
Step-by-step explanation:
x + 13 + 10x + 13 + 2x - 2 = 180 add x's
13x + 13 + 13 - 2 = 180 add number's on left
13x + 24 = 180 subtract 24 from both sides
13x = 156 divide both sides by 13
x = 12
x + 13 = 12 + 13 = 25
10x + 13= 10(12) + 13 = 133
2x -2 = 2(12) - 2 = 22

Answer:
x = -360
Step-by-step explanation:
x/9 = x/10 - 4
=> x/9 - x/10 = -4
=> x/10 - x/9 = 4
=> 9x/90 - 10x/90 = 4
=> -x/90 = 4
=> -x = 90(4)
=> x = -360

Answer:
Step-by-step explanation:
7). Since, ∠4 and ∠5 are the linear pair of angles,
m∠4 + m∠5 = 180° [Supplementary angles]
72° + m∠5 = 180°
m∠5 = 180° - 72°
m∠5 = 108°
8). Since, ∠6 and ∠7 are the vertically opposite angles,
Therefore, ∠6 ≅ ∠7
m∠6 = m∠7
3x + 94 = 9x - 38
9x - 3x = 94 + 38
6x = 132
x = 22
m∠6 = 3(22) + 94 = 160°
m∠7 = 9(22) - 38 = 160°
9). Since, ∠2 and ∠3 are the linear pair of angles, both the angles will be supplementary.
m∠2 + m∠3 = 180°
(13x + 54) + (2x + 36) = 180°
15x + 90 = 180°
15x = 90
x = 6
m∠2 = 13(6) + 54 = 132°
m∠3 = 2(6) + 36 = 48°

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
Area of the square = a²
The exact value of the side length of a square with an area of 95 square units can be found by taking the square root of 95.
√95 ≈ 9.74679434481 (approximate value)
Hence , the exact value of the side length of the square is approximately 9.74679434481 units

Samantha works in a chocolate factory at a conveyor belt that is 18 inches wide and moves large amounts of chocolate to packaging. She counts 225 chocolates in a rectangular section of the conveyor belt measuring 6.5 inches long and 18 inches wide. What is the approximate number of chocolates per square inch of the conveyor belt, rounded to the nearest hundredth?
Answer:
1.92 chocolates per in²
Step-by-step explanation:
Given that:
Dimension of conveyor belt :
6.5 inches long and 18 inches wide (6.5in * 18in)
Area of conveyor belt = 6.5 * 18 = 117 in²
Number of chocolate = 225
Number of chocolates per square inch :
225 / 117
= 1.9230769 chocolates
= 1.92 chocolates per in²

HELP ASAP!! Mrs. Walsh is in search of a birthday gift for her niece and decided to shop at Kohls. Mrs. Walsh just had a nice shopping spree there, therefore she had $15 Kohls cash to use. She also had a friends and family coupon for 25% off the entire purchase. Mrs. Walsh made sure to search the fine print and there was nothing noted saying she cannot use BOTH coupons. Which coupon should Mrs. Walsh use first, or does it matter? Will this always be the case? How do you know? Show your work.
Answer:
The best answer would be the 25% off the entire purchase. Say for example Mrs. Walsh was willing to spend 100$ that would be 25% dollars she saved. But when it comes to save the most amount of money. If she spends under 60 dollars use the 15 dollars off. If it’s over 60 use the 25% off coupon
