DONE
I need the last part
Answer:
1. Geometric sequence
2. 4,096
3. 5,460
Step-by-step explanation:
Part 1
Since the number of letters sent is multiplied by 4 for any subsequent term, the sequence is an example of a geometric sequence as it grows exponentially.
Part 2
Given a geometric sequence, the nth term is determined using the formula:
[tex]T_n=ar^{n-1},$ where r=common ratio, a=first term, n=number of terms[/tex]
In this case,
a=1 (i.e. Nyah)
r=4
Since we want to determine how many letters will be sent on the sixth mailing(i.e after Nyah), n=7
Substituting
[tex]T_6=1*4^{7-1}\\=4^6\\=4096[/tex]
Part 3
To determine how many people would have participated by the sixth mailing, we are required to find the sum of the first seven terms of the geometric sequence.
We use the sum of a geometric sequence formula
[tex]S_n=\dfrac{a(r^n-1)}{r-1} \\S_7=\dfrac{1(4^7-1)}{4-1} \\=\dfrac{16383}{3}\\\\=5461[/tex]
Therefore, excluding Nyah, 5460 people would have participated by the sixth mailing.
Answer:
1. Geometric sequence

Answer:
Step-by-step explanation:
6)Let the number be x
Product of a number and -4 = x * -4 = -4x
Product of a number and -4 increase by 3 : -4x + 3
-4x +3 = 9
Subtract 3 from both sides
-4x + 3 - 3 = 9 - 3
-4x = 6
Divide both sides by (-4)
-4x/-4 = 6/-4
x = -3/2
x = -1 1/2
7)Let the number be x
[tex]\frac{x}{6}-9=11\\\\[/tex]
Add 9 to both sides
[tex]\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\[/tex]
Multiply both sides with 6
[tex]\frac{x}{6}*6=20*6\\\\[/tex]
x = 120

A customer states that she was shorted in change by receiving only 23 cents change from $3.00
dollars instead of 32 cents. How would you handle this?
Answer:
First, I would check and see if she was correct. If she wasnt, I would simply show her why she was incorrect. If I was to accidently short her, I would give her the money and move on with my day. if she refused to leave after showing her that I gave her the correct amount of money, she would probably call for the manager. I'd get the manager, explain what happened, and the annoying customer would most likely get kicked out of the store.

Lucia speed walks 3 kilometers in of an hour. At 2/3 that rate, how many meters does she speed walk per minute?
Answer:
2000 meters
Step-by-step explanation:
The first step in this problem is to find 2/3 of 3 kilometers per hour.
2/3 * 3/1 = 6/3. This can be simplified to 2 kilometers per hour.
Now, find the rate of meters per minute. To do so, multiply 2 by 1000.
2 * 1000 = 2000
Therefore, at 2/3 of Lucia's rate, she walks 2000 meters per minute.
Answer:
The answer is 75 meters per minute.
Step-by-step explanation:
Ok I been seeing people say 2000 meter which is WRONG. 1 kilo= 1,000 meters
2/3 of an hour= 40 minutes
3,000 meters/40mins= 75 meters per minute

List the sides in ΔEFG in order from smallest to largest. Picture includes possible solutions
The list of sides in triangle EFG in order from smallest to largest is option A) EF, EG and FG.
What is Triangle?A triangle is a polygon in two dimension which has three vertices, three edges and three angles.
There are different kinds of triangles like equilateral triangle, isosceles triangle and so on.
Given triangle EFG and the angles of the triangle is also given.
The largest side of a triangle is the side which has the largest opposite angle.
Or in other words, the side opposite to the larger angle will be having larger length.
Here the largest angle is 63°. So the side opposite to this angle which is side FG is having largest length.
Then comes the angle 62°. The side opposite to this is EG which is the side standing next to FG.
The smallest angle is 55° and the side opposite to it which is EF is having smallest side length.
So the order from smallest to largest is EF, EG, FG.
Hence the sides in order from smallest to largest is EF, EG, FG.

To find the area of a triangle, multiply the base by the height, and then divide by 2.2.4 x 3.7 = 8.88next i divide by 28.88 / 2 = 4.44so my answer is 4.44Hope this helpsask questions if it is wrongBrainliest plzA cylinder and its dimensions are shown. Which equation can be used to find V, the volume of the cylinder in cubic centimeters?
A) V = π(3.5h)2
B) V = π(7h)2
C) V = π(3.5)2h
D) V = π(7)2h
Answer:
The volume of a cylinder is given by the equation:
V = π(R)^^2*h
where π = 3.14, R is the radius and h is the height.
If in the image we see that the radius is 7, then the correct option is D.
If in the image we shee that the DIAMETER is 7 (a linea that goes from end to end of the circle and goes trough the middle) then we know that the radus is half of the diameter, 7/2 = 3.5
in this case he correct option is C.
Answer:
There is no image included, so I cannot give a direct answer. However, you should be able to figure out the answer after my explanation.
Step-by-step explanation:
‼️now pay attention in order to get this question correct‼️
Well, this is a simple problem, since you don’t necessarily need to solve it. First, you need to know the formula of volume for a cylinder. This is: V = πr²h.
Figure out π. Π is a number too long to be written, so we found it up to 3.14.
π = 3.14
Now figure out the radius, for r. This, isn’t my problem to solve because I don’t have a picture of the cylinder so I cant determine so.
The equations don’t specify any height written, so we don’t have to solve for h yet.
This is your job now. So far, I’ve only figured out π, now find the radius, take that number, and fit it in the parentheses. V = π(_)²h. That’s it. Now look at the options, and pick the option that matches what you’ve already written.
I hope I’ve helped, taking time to write this... but I hope you wouldn’t mind brainliest lol c: take care and have a nice day!
In the diagram, which two angles are alternate interior angles with angle 14?

Angle 4 and Angle 12
Angle 3 and Angle 9
Angle 2 and Angle 10
Angle 12 and Angle 15
Answer:
Angle 4 and Angle 12Step-by-step explanation:
Angles 4 and angles 12 are alternate interior angles with 14.
Angle 4 is alternate interior with angle 14, and angle 12 is alternate interior with angle 14.
The person that answered above me is wrong. But there is some truth to his answer, because angle 3 is alternate interior with angle 9, but they are NOT alternate interior WITH angle 14.
That is why many people answering this question fail. The question says:
In the diagram, which two angle ARE alternate interior angles WITH angle 14?
To finally answer the question completely, angles 4 and 12 ARE alternate interior angles WITH angle 14.
Therefore the guy above me is 100% wrong.
Hence, the right option is (A).
