The steps for the geometry sequence with the help of two terms of the sequence, make a system of equation and solve them to find common ratio and first term.
What is geometric sequence?
Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
It can be given as,
[tex]a_n=a_1r^{n-1}[/tex]
Here, a₁ is the first term of the sequence and r is the common ratio.
The fourth term and sixth term given in for the geometric sequence are 3 and 3/16. For the fourth term,
[tex]a_4=a_1r^{4-1}\\3=a_1r^3[/tex] ...1
For the sixth term,
[tex]a_6=a_1r^{6-1}\\\dfrac{3}{16}=a_1r^5[/tex] ....2
On solving, we get, a₁=192 and r=1/4. Thus, the geometric sequence can be given as,
[tex]a_n=a_1r^{n-1}\\a_n=192\times\dfrac{1}{4}^{n-1}[/tex]
Hence, the steps for the geometry sequence with the help of two terms of the sequence, make a system of equation and solve them to find common ratio and first term.

What is P(not odd)? if u roll a 6-sided die
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
We have to find the probability of not getting odd, whole rolling a 6 sided die ~
Actually dices have 3 odd numbers (1 , 3 , 5) and 3 non - odd numbers (2 , 4 ,6)
When we roll a dice, we may get any of the six numbers, so total possible outcomes are 6
and, The number of Favorable outcomes is 3, i.e non - odd numbers.
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{favourable \: outcomes}{total \: \: outcomes} [/tex]
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{3}{6} [/tex]
[tex] \qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{1}{2} \: \: \: or \: \: \: 0.5[/tex]
Answer:
½
Step-by-step explanation:
Not odd (even) numbers from 1 - 6 = 2, 4, 6
Any of these 3 numbers can come when rolling a cubical 6 - sided dice.
Then,
P (not odd)
= Favourable outcomes / total number of outcomes

In a group of 60 workers, the average salary is $80 a day per worker. if some of the workers earn $75 a day and all the rest earn $100 a day how many workers earn $75 a day?
The total number of workers that earn $75 per day is 48
What is average salary?The average salary is calculated based on reported salaries of respondents. The average salary definition is to add the salaries in the sample together, then divide by the number of respondents.
Given that:
In a group of 60 workers, the average salary is $80 a day per worker.
If some of the workers earn $75 a day and all the rest earn $100 a day.
Let 'x' be the total number of workers that earn $75 per day.
So, the total number of workers that earn $100 per day is (60 - x).
As the average salary of 60 workers is $80.
Then,
[tex]\frac{75x + 100(60-x)}{60} =80[/tex]
or, 75 x + 6000- 100x = 80*68
or, -25x= -1200
x= 48
So, the total number of workers earn $75 per day is 48.

Claire says that she can find the volume of any cylinder as long as she can measure the circumference and height is she correct
Answer:
Yes, she is correct. Volume of the cylinder is V = πr²h. Therefore we need height and radius to calculate the volume. Height is given and the radius can be calculated from the circumference.
Step-by-step explanation:
Volume of cylinder
[tex]V = \text{area of circle} \times \text{height}\\V = \pi r^2 \times h[/tex]
For the volume of the cylinder we need the radius of the circle and height of the cylinder. The height is already known.
We can find the radius from the circumference.
Cirumference of the circle
[tex]C = 2 \pi r[/tex]
We can get the radius from rearranging the equation.
[tex]r = \frac{C}{2 \pi}[/tex]
Since C (circumference) is known we can easily calculate the radius.
With that we have all the needed information (height and radius) to calculate the volume of the cylinder.

Does anybody know this? I had it right before but now I don't remember the answer. Find the surface area of the square pyramid.
Answer:
The surface area of the square pyramid is 280 units².
Step-by-step explanation:
As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:
[tex]A=2bs+b^2[/tex]
From the figure, it is clear that
length of its base = 'b' = 9slant height = 's' = 10substituting the values in the formula
[tex]A=2bs+b^2[/tex]
[tex]A=2[/tex] [tex](10)[/tex] [tex](9)+(10)^2[/tex]
[tex]=2[/tex] [tex](10)[/tex] [tex](9)+100[/tex]

[Subtract Integers]
[tex]\rightarrow \sf \dfrac{13}{36}[/tex]
Answer:
13/36.
Step-by-step explanation:
First convert to improper fractions:
10 1/9 = (10*9 + 1)/9 = 91/9.
9 3/4 = (9*4 + 3)/4 = 39/4.
Next find the Lowest Common Denominator of 9 and 4.
This is 9*4 = 36.
Now convert both fractions to 36th:
For 91/9 we multiply by 4/4 and for 39/9 we multiply by 9/9
91*4 / 9*4 = 364/36 and 39*9 / 9*4 = 351/36, so we have:
364/36 - 351/36
= 13/36

Answer:
Step-by-this may be done by rearranging the equation. First, we start with the given equation:

Feeling anxious about another pandemic induced run-on toilet paper, Mrs. Phillips is making room in a closet for hording Angel Soft toilet paper. Using the Fermi process, she wants to estimate the number of rolls of toilet paper she can fit into a rectangular section of a closet with dimensions of length 36 inches, width 36 inches, height 108 inches.

Volume of closet /Volume of rolls139968/73.61901.71902 rollsAnswer:
1372
Step-by-step explanation:
Rectangular closet dimensions:
length = 36 inwidth = 36 inheight = 108 inModelling the roll of toilet paper as a cylinder with dimensions:
diameter = 5 inheight = 3.75 inIf we sit the rolls of toilet paper in the closet with their circular ends as their bases, then we can calculate the number of rolls that cover the base of the closet by dividing the length (and width) of the closet by the diameter of the toilet roll.
⇒ 36 in ÷ 5 in = 7.2 in
Therefore, we can fit 7 toilet rolls along the length and 7 toilet rolls along the width of the closet, meaning that we can fit 7 × 7 = 49 toilet rolls over the base of the closet.
Now calculate how many toilet rolls we can stack on top of each other.
To do this, divide the height of the closet by the height of the toilet roll:
⇒ 108 in ÷ 3.75 in = 28.8
Therefore, we can stack 28 layers of 49 toilet rolls in the closet.
So the total number of toilet rolls = 28 × 49 = 1372
There are other ways of stacking the toilet rolls in the closet (for example, turning them on their side), however, we cannot calculate the number of rolls the closet fits by simply dividing the volume of the closet space by the volume of a toilet roll, since the toilet rolls are cylinders and so there will always be some space between them.

Let $a_1, a_2, a_3,\dots$ be an arithmetic sequence. if $a_{23} = \dfrac23$ and $a_{53} = \dfrac32$, what is $a_{35}$?
Using an arithmetic sequence, it is found that the 35th value of the sequence is given by: [tex]a_{35} = 1[/tex].
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term.
Considering that we have the mth term as reference, the nth term is also given as follows:
[tex]a_n = a_m + (n - m)d[/tex]
In this problem, we have that:
[tex]a_{23} = \frac{2}{3}, a_{53} = \frac{3}{2}[/tex].
Hence:
[tex]a_n = a_m + (n - m)d[/tex]
[tex]a_{53} = a_{23} + (53 - 23)d[/tex]
[tex]30d = \frac{3}{2} - \frac{2}{3}[/tex]
[tex]30d = \frac{9 - 4}{6}[/tex]
[tex]30d = \frac{5}{6}[/tex]
[tex]d = \frac{1}{36}[/tex]
Then the 35th term is:
[tex]a_{35} = a_{23} + 12d = \frac{2}{3} + 12\frac{1}{36} = \frac{2}{3} + \frac{1}{3} = 1[/tex]
