Here are the first five terms of a sequence.
3 8 17 30
47
Find an expression, in terms of n, for the nth term of this sequence.
Answers
Answer:
So the formula for the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero
Step-by-step explanation:
3 8 17 30 47
First term = 3
Second term = 8
Third term = 17
Fourth term = 30
Fifth term = 47
Second term - first term = 8-3=5
Third term - second term = 17-8= 9
Fourth term - third term = 30-17=13
Fifth term - fourth term = 47-30=17
So the AP is 5 9 13 17
We find out that the common difference is 9-5 = 4
The formula for nth term of the AP is
= a + nd
So the formula fir the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero

Answer:
120 inches
Step-by-step explanation:
Set up a ratio.
1.5 inches = 30 inches
6 inches = x
Cross multiply.
30(6) = 1.5(x)
180 = 1.5x
Divide.
180 ÷ 1.5 = 120 inches
or
6 ÷ 1.5 = 4
4 × 30 = 120 inches

Use the information given to answer the question. Dot plots of two data sets are shown.
Which statement is true?
A. The range of Set 1 is equal to the range of Set 2.
B. The range of Set 1 is greater than the range of Set 2.
C. The range of Set 1 is less than the range of Set 2.
D. The range of each set cannot be compared.
Answers
Answer: The correct answer is option D, "The range of each set cannot be compared."
Step-by-step explanation:
From the given dot plots, it can be observed that the range of Set 1 is from 1 to 9 and the range of Set 2 is from 2 to 10. Therefore, the statement "The range of Set 1 is less than the range of Set 2" is false. On the other hand, the statement "The range of Set 1 is greater than the range of Set 2" is also false.

C.12.6
D.12.66
pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Petra is making a batch of extra large donuts by stamping circles in dough using a pastry stamp with a diameter of 5 inches. For the donut hole, she stamps out a circle using a pastry stamp that has a diameter of 2 inches.
How many square inches of dough are left in the donut after the hole has been removed?
Step 1 - Find the radius of each circle
Step 2 - Find the area of the large circle
Step 3 - Find the area of the small circle
Step 4 - Area of large circle minus area of small circle
Area = \(\pi\)²
Describe how you solved this problem using complete sentences and include all relevant formulas and calculations. Use 3.14 for \(\pi\)
Answers
Answer:
16.49
Step-by-step explanation:
First we are going to find the area of the larger circle. You don't need to find the radius, you can just use the diameter(the radius is 2.5). 3.14 times 2.5 squared=19.63. Next, the radius of the smaller circle is 1. So, 3.14 ^1 squared=3.14 19.63 - 3.14= 16.49
An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer: The total percentage decrease in the investor's stock account is 34%
Step-by-step explanation:
The investor's stock in Company A= $3800
The investor's stock in Company B= $3400
Percentage decline in stock of company A= 22%
Decline in value of stock of company A= 3800× 22/100
= 38×22
= $836
Percentage decline in stock of company B= 3400×12/100
= 34×12
=$408
Total decline in wealth of investor= 836+ 408
= $1244
Total percentage decline in wealth= 1244×100/7200
= 124400/7200
= 17.27%
The percentage decrease in investor's stock is 17.27%

Jack and his friends buy 4 tickets to the show . They also each spend $2 on a drink. They spend $18 in all. Which equation matches the situation.
Answers
Answer:
2(x + 4) = $18
Step-by-step explanation:
Let Jack be x
Jack and his friends buy 4 tickets means,
x + 4
Each spend $2 on a drink means,
2 * (x + 4) = 2(x + 4)
Totally, they spend $18
The final equation :
2(x + 4) = $18
Answer:
2x + 4 = 18
Step-by-step explanation:
jack and his friends bought 4 tickets so number 4 is a constant.
each of them spends $2 on a drink
let x be the total number of friends
they collectively spend $18 in all
thus, the equation can be written as,
2x + 4 = 18
