Tell whether each sequence is arithmetic or geometric and determine the 11th term. (a) 3, 10, 17, 24, ... arithmetic or geometric? 11th term: (b) 4, 12, 36, 108, ... arithmetic or geometric? 11th term: (c) -20, -24, -28, -32, ... arithmetic or geometric? 11th term:
Step-by-step explanation:
(a) 3, 10, 17, 24, ...
d=10-3=17-10=7 then it is arithmetic sequence
a(n) = a +(n-1)d
a(11) = 3 +(11-1)7
=73
(b) 4, 12, 36, 108,
r=12/4=36/12=108/36=3
So it is geometric
By using this equation:
and we have a(1)=4 , r=3
a(11)=4*(3)^(11-1)
=236196
(c) -20, -24, -28, -32, ...
d=-24+20=-28+24=-4 then it is arithmetic sequence
a(11) = -20 +(11-1)-4
=-60
hope this helps

Dee has collected no fewer than 388 coats for charities. She gave 64 of the coats to her church and donated the remaining coats equally to local shelters. If Dee gives a minimum of 36 coats to each shelter, how many shelters receive coats?
Answer:
9 shelters
Step-by-step explanation:
Subtract 64 from the total number of coats to get the total amount of coats donated to shelters:
388 - 64 = 324
Then, divide 324 by 36, since that's the minimum number of coats given to each shelter:
324 ÷ 36 = 9
So at least 9 shelters received coats.
Dee gives a minimum of 36 coats to each shelter, 9 shelters receive coats.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Dee has collected no fewer than 388 coats for charities.
Let n be the number of coats.
n = 388
She gave 64 of the coats to her church and donated the remaining coats equally to local shelters.
Then,
n = 388 - 64
n = 324
The 324 remaining coats equally to local shelters.
She gave 36 to each shelter.
That means, use division operation,
the number of shelters = 324 / 36
The number of shelters = 9
Therefore, the number of shelters is 9

Michael buys a basket of mangoes on sale for $4 before tax. The sales tax is 12% What is the total price Michael pays for the basket of mangoes?
Answer:
$4.48
Step-by-step explanation:
First, you have to convert the percentage into a decimal.
12% x 100 = 0.12
Second, you multiply the decimal with the cost of the product before tax.
$4 x 0.12 = $0.48
This number is the amount of money you will have to pay in tax.
Third, you add the tax amount to the original cost of the product to get the total price.
$4 + $0.48 = $4.48

Read this excerpt from I Never Had It Made. Here we go again, I thought. Another time-wasting experience. But Sukeforth looked like a sincere person, and I thought I might as well listen. I agreed to meet him that night. When we met, Sukeforth got right to the point. Mr. Rickey wanted to talk to me about the possibility of becoming a Brown Dodger. If I could get a few days off and go to Brooklyn, my fare and expenses would be paid. At first I said that I couldn't leave my team and go to Brooklyn just like that. Sukeforth wouldn't take no for an answer. He pointed out that I couldn't play for a few days anyhow because of my bum arm. Why should my team object? I continued to hold out and demanded to know what would happen if the Monarchs fired me. The Dodger scout replied quietly that he didn't believe that would happen. I shrugged and said I'd make the trip. I figured I had nothing to lose. Which statement best summarizes this excerpt?

Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 3/4 feet long.
Each president's picture is 6 inches wide.
(THE FIRST PICTURE WOULD GO HERE)
If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer:
8 pictures
Step-by-step explanation:
Given
Step-by-step explanation:
Determine the number of pictures
First, we need to calculate the length of the available space
This is calculated by subtracting the width of the window from the width of the wall.
Convert fraction to decimal
Since, the pictures are placed side by side.
This means that, there's no empty space between them.
Number of pictures is:
Convert feet to inches
Hence, 8 pictures can fit the wall

3 bears = 3
1 bear = 3 ÷ 3
1 bear = 1
2 glasses + 1 bear = 5
2 glasses + 1 = 5
2 glasses = 5 - 1
= 4
1 glasses = 4 ÷ 2
1 glasses = 2
1 Cyxus + 1 bear + 1 Cyxus + 1 glasses = 9
2 Cyxus + 1 + 2 = 9
2 Cyxus = 9 - 1 - 2
= 6
1 Cyxus = 6 ÷ 2
1 Cyxus = 3
1 glasses + 1 bear + 1 glasses + 1 Cyxus - 1 bear - 1 glasses = ?
2 + 1 + 2 + 3 - 1 - 2 = 5
Find the square root of the number.
V=36
The square root is
Answer:
6i is the square root
Step-by-step explanation:
The square root of a negative number means there are no real numbers we can use, so it must be an imaginary number. The square root of 36 is 6, the square root of any negative has (i) or an imaginary number in it. As (i) squared is equal to -1. So 6i squared is 36(-1) or -36. Making the answer 6i.

Answer:
Not similar
Step-by-step explanation:
For a rectangle you would make a equation with length a over length b equalibg width a over width b. I'll use the problem and show it in an equation below.
[tex] \frac{12}{24} = \frac{8}{18} [/tex]
There are a few ways to solve this, 1, by simplifying, and the other cross multiplying. I like cross multiplying more, so I'll explain it like that. To cross multiply you multiply the numerator of one fraction by the denominator of the other.
[tex]12 \times 18 = 216 \\ 24 \times 8 = 192[/tex]
Because these values are not equal, the rectangles are not similar.
The relationship between the radius, r, of a sphere and its surface area, A, is r = ( A /4 π ) 1/2. What is the radius of a sphere that has a surface area of 64π square units?
Answer:
8 units
Step-by-step explanation:
Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;
r = 1/2( A /4 π )
We are to find the radius r when Area A is 64π
Substitute A = 64π into the expression and get r as shown;
Recall that: r = 1/2( A /4 π )
r = 1/2( 64 π/4 π )
r = 1/2(16)
r = 16/2
r = 8units
Hence the radius of the sphere will be 8 units

A proportional relationship between the number of pounds of lettuce (x) and the price in dollars (y) is graphed, and the ordered pair (5, 3) is on the graphed line. Part A: What is the price of 1 pound of lettuce? Show your work. (8 points) Part B: What does the ordered pair (10, 6) on the graph represent? Explain in words.
Answer:
A) $0.6
The point (5,3) means that you get 5 pounds of lettuce for 3 dollars, which means that one pound of lettuce would cost 3/5 dollars.
B) It tells us that 10 pounds of lettuce costs $6.
The x value of the point on the this graph tells us the number of pounds of lettuce and the y value of the point tells us the cost of those pounds of lettuce.
