2. 1 * 3 = 3'
3. 3*3 = 9
4. 9*3= 27
5. 27*3 = 81
6. 81*3 = 243
7. 243
Hope this helps!
The required 7th term in the given geometric sequence would be 243.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The sequence given in the question follows as:
1/3, 1, 3, 9, . . .
This sequence follows the pattern of a geometric progression, where each term is obtained by multiplying the previous term by a fixed number, called the common ratio.
The common ratio for this sequence is 3.
To find the nth term in a geometric progression, you can use the formula:
aₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
Plugging in the values for this sequence, we have:
[tex]a_7 = 1/3 \times 3^(7-1) = 1/3 \times 3^6[/tex]
= 1/3 x 729 = 729/3 = 243
Therefore, the 7th term in the sequence is 243.

whats the mean of -54 -32 -70 -25 -65 and -42 please help need the answer for a math quiz?!
Step-by-step explanation:
To find the mean, you add all the numbers and divide by how many there are.
In this case, you add -54,-32,-70,-25,-65, and -42. Then you divide by 6 because there are 6 numbers.
When you add them all, you get -288.
Now divide.
-288/6=-48
Hope it helps!
Answer:
-48
so you add all the numbers together, which will give you -288
there are 6 terms, so you divide -288 by 6
gives you your answer of -48
What is the division rule for 2?
Answer:
The Rule for 2 : Any whole number that ends in 0, 2, 4, 6, or 8 will be divisible by 2. This is the number four hundred fifty-six thousand, seven hundred ninety-one, eight hundred twenty-four. We can tell if 2 divides into this number without a remainder by just looking at the last digit.

What is a Set?The definition of a set in mathematics is a group of things whose components are unchangeable and fixed. In other words, a set is accurately described as a group of data that does not pass from one person to another. The items can be written in any sequence, but they cannot be repeated in the set. Capital letters are used to denote the set.
Several other kinds of sets include the infinite set, the finite set, the equivalent set, the subset, the universal set, and the superset. Each kind of set has a different place in calculations. Sets are essentially used to represent large amounts of data and collections of data in everyday life. Thus, in this article, we'll learn about and talk about the universal set.
As per the given data:
The integer set is {7, -7, -3, 3}
For the greatest value, arranging the set in ascending order:
{-7, -3, 3, 7}
The greatest value will be 7.

Mr. Hernandez has 41 feet of rope to enclose a pentagonal grazing area for his sheep. Sides of the pen are represented by: x, 7 - 5x, 3x - 2, 3x + 4, 5-3x. Which inequality could be used to find the possible perimeters of the grazing area?
Answer:
Option (B)
Step-by-step explanation:
Length of the rope Mr Hernandez has = 41 feet
He wants to enclose an area in the shape of a pentagon.
Therefore, minimum length of the rope required = perimeter of the pen
Perimeter of the pentagonal pen = Sum of the measures of all five sides of the pen
Perimeter = x + (7 - 5x) + (3x - 2) + (3x + 4) + (5 - 3x)
= (-x + 14)
Now the length of the rope should be more than and equal to the perimeter of the pen to cover.
41 ≥ (-x + 14)
Or
-x + 14 ≤ 41
Therefore, Option (B) will be the answer.

The sum of 8X and 3X
Answer:
8x + 3x=11x
Explain:
Every time you see the word sum, you add
AB = 6x + 2 and
BC = 5x + 3
Find AC.
Answer:
AC = 3x + 3 (answers may vary)
Step-by-step explanation:
AB = 6x + 2
Answers may vary for this question,
Let's say that,
B = 4x + 1
So that means that,
A = 2x + 1
BC = 5x + 3
Since we chose
B = 4x + 1,
we must subtract B from BC to get C,
C = x + 2
Now we add A and C to get AC,
A = 2x + 1
C = x + 2
AC = 3x + 3

Solve this inequality: 4.2x+5.6<7.2-8.3x please give the steps.
Answer:
[tex]x<\frac{16}{125}[/tex]
Step-by-step explanation:
First we will multiply everything by 10 to get rid of the decimals.
[tex]4.2x*10+5.6*10<7.2*10-8.3x*10\\42x+56<72-83x[/tex]
Subtract 56 from both sides:
[tex]42x+56-56<72-83x-56\\42x<-83x+16[/tex]
Add 83x to both sides:
[tex]42x+83x<-83x+16+83x\\125x<16[/tex]
Divide both sides by 125:
[tex]\frac{125x}{125}<\frac{16}{125}\\x<\frac{16}{125}[/tex]

EXAMPLE : 3×5=15
27×5= 135
Answer:
Truefo example: 3•3 = 9 (=2•4+1) 5•7 = 35 (=2•17+1) 11•13 = 143 (=2•71+1)Step-by-step explanation:
If k is any integer then 2k is even number and 2k+1 is odd number
If n is any other integer then 2n+1 is also some odd number
Their product:
(2k + 1)(2n + 1) = 2k•2n + 2•1k + 1•2n + 1•1 = 2(2kn + k + n) + 1
k,n are integers so 2kn also is integer.
Sum of integers is integer too, so if we name 2kn+k+n = z, then product of any two odd integers is 2z+1 which is an odd number.

can you help me find the area of the circle
Answer:
29.26 [tex]units^{2}[/tex]
Step-by-step explanation:
Area of a circle = [tex]\pi r^{2}[/tex]
Area of a circle = 3.14 * 3 * 3 ( so i used pi as 3.14 ) then the radius is 3
Area of a circle = 9.42 * 3 ( first 3.14 times 3 is 9.42)
Area of a circle = 28.26 ( 9.42 times 3 is 28.26)

Liliana noted that the temperature was 45 degrees when she woke up. At noon she started recording the increase in degrees from the morning temperature.
A histogram titled Temperature has time of day on the x-axis and increase in degrees on the y-axis. 12 to 2 pm is 12 degrees; 2 to 4 pm is 18; 4 to 6 pm is 24; 6 to 8 pm is 20; 8 to 10 pm is 14; 10 to 12 am is 5.
Which statement most reasonably explains the hours after the peak increase in temperature?
The temperature always rises after a peak.
The temperature increase went down because the thermometer’s battery was losing power.
The temperature increase went down because it became cooler as the sun went down for the night.
The temperature rose after the peak when the sun came out from behind a cloud bank.
Answer: C
Step-by-step explanation:
The temperature increase went down because it became cooler as the sun went down for the night.

Answer:
The first answer choice.
Answer choice A.
Step-by-step explanation:
The domain of a function would be the set of all possible x-values of that function.
Since we are looking for the domain, the set of the possible x-values, we can eliminate any answer choices that are a set of y-values. B and D are eliminated.
From what we can see in the table, the possible x-values of the function are -6, -1, 0 and 3. Although C does include these values in the set, it also includes many other values. As we can see, answer choice A includes the x-values given in the table and only those values. Therefore, answer choice A is the correct answer.
