6) The circumference of a circle is
approximately 37.68 centimeters. What is the radius of the circle to the nearest centimeter?
A. 6 cm
C. 12 cm
B. 8 cm
D. 16 cm
Answer: A, 6 cm
Step-by-step explanation:
Circumference is 2(radius) * pi.
A. 12pi C. 24pi B. 16pi D. 32pi
Assuming pi is roughly 3,
A = 36
C = 72
B = 48
D = 96
A is the closest and if you actually used pi, it would be about 3.14159265 which would make the circumference slightly over 36, which 37.68 is.
Hope this helped.

regular number after 167, 118, 82, 57, 41, ?
Answer...
32!!
Step-by-step explanation:
Subtract the numbers to see a pattern of decreasing odd numbers
167-118 = 49
118-82 = 36
82-57 = 25
57-41 = 16
The difference between is 13 then 11 then 9 so the next number should be x-7
Can some explain how to do this.
We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.
How to simplify the expression?Remember the exponent property:
[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]
Here we have the expression:
[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2}[/tex]
We can reorder this to get:
[tex]\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2} = \frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2}[/tex]
The right side can be simplified to:
[tex]\frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2} = 64.04*10{12 - 3 - 2} = 64.04*10^{7}[/tex]
Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:
[tex]6.404*10^8[/tex]
Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).

b. (QS 2) Consider any years that showed somewhat unusual growth rates and provide examples that might have contributed to the anomalous growth.
c. (QS 1) Develop a linear model for the expected attendance t years after 2011.
d. (QS 3) Use the model from c) to project the expected attendance for 2025 and 2030.
e. (QS 3) What are some important factors that could help/hinder future attendance? Explain how these might impact your projections above including whether your model should be more accurate for 2025 vs 2050.
The average rate of change in attendance from 2011-2021 is 1.132 per year
Average rate of change in attendance from 2011-2021From the graph, we have:
Population in 2011 = 47.45Population in 2021 = 58.77The average rate of change is then calculated as:
Rate = (58.77 - 47.45)/(2021 - 2011)
Evaluate
Rate = 1.132
2022 is 11 years from 2011.
So, the predicted annual attendance for 2022 is;
Attendance = 47.45 + 1.132 * 11
Attendance = 59.90
Year with unusual growthThe years with unusual growth are 2020 and 2021.
This is so because they have the same attendance.
The factor that might have contributed to the anomalous growth include
Government policiesNatural occurrenceThe linear model for the attendanceIn (a), we have:
Attendance = 47.45 + 1.132 * 11
Express as a function
y(t) = 47.45 + 1.132(t)
Expected attendance for 2025 and 20302025 is 14 years from 2011.
So, we have:
y(14) = 47.45 + 1.132(14)
y(14) = 63.298
2030 is 19 years from 2011.
So, we have:
y(19) = 47.45 + 1.132(19)
y(19) = 68.958

Jenny is preparing a roast chicken dinner in honour of her daughter coming back for the holidays after studying abroad. Her daughter will be on Flight BM1264. Jenny will arrive at the airport ten minutes before the flight arrives and will leave with her daughter fifteen minutes after it lands. Her journey to the airport takes 25 minutes. Jenny wants to do all the preparation for the meal before leaving for the airport. It takes 30 minutes to prepare. She will leave for the airport straight after finishing the preparation. Jenny has bought a 2.4kg chicken. It takes 35-45 minutes per kg plus an additional 30 minutes to cook the chicken. Jenny will start cooking five minutes after getting back from the airport. QUESTION IS: HOW LATE CAN THEY EAT DINNER, ALSO PLANE ARRIVES AT 4PM
The addition is one of the four fundamental mathematical operations. Jenny can have dinner at 7 pm and 7.5 mins.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
The time can be calculated as,
Time taken for preparation = 30 minTime is taken to travel to airport = 25 minsShe will wait for 10 mins before the flight arrive = 10 minFlight lands at 4 pm
She will leave 15 mins after the flight lands = 15 minsIt takes 25 mins to travel back home ⇒ 15 + 25 minsShe will start cooking after 5 mins ⇒ 15+25+5 minJenny has bought a 2.4kg chicken. It takes 35-45 minutes per kg plus an additional 30 minutes to cook the chicken. Time needed for cooking the chicken = (2.5×45 + 30) = 142.5 min
⇒ 15+25+5+142.5 min
Thus, the total time it takes for Jenny to cook the food starting when the flight lands are ⇒ 187.5 mins = 3 hours 7.5 mins
Since the flight lands at 4 pm
⇒ 4 pm + 3 hours 7.5 mins
⇒ 7 pm and 7.5 mins

At noon, ship A is 20 nautical miles due west of ship B. Ship A is sailing west at 17 knots and ship B is sailing north at 21 knots. How fast (in knots) is the distance between the ships changing at 3 PM? (Note: 1 knot is a speed of 1 nautical mile per hour.)
The distance between the ships is 26.65.
How to illustrate the distance?Based on the information given, after 3 hours, the distance of ship B will be:
= 20 + (17 × 3)
= 71.
A = 21 × 3 = 63
Well calculate the square root which will be:
A² + B² = 71² + 63²

Reason:
To be able to count the number of items inside set [tex]A \cap C[/tex], we first need to determine what this set looks like. In other words, we need to know the number(s) inside this set.
The upside down U symbol is the intersection symbol. It indicates we want to find what the sets A and C have in common. In this case, it's the value "4" and nothing else. This number is in both set A and set C at the same time. It might help to draw a venn diagram as you see below. I'm ignoring set B entirely since your teacher is not asking about the set in this problem.

what is the next # in this sequence 3, 5, 12, 55, 648
Answer:
35 585
Step-by-step explanation:
Each term is the product of the previous two terms minus the term that is two before
3*5 - 3 = 12
5 x12 - 5 = 55
12 x 55 - 12 = 648
55 * 648 - 55 = 35 585
or each term is term that is two before x (term before -1)
3 (5-1) = 12
5 x (12-1) = 55
12 * (55-1) = 648
55 * ( 648-1) = 35 585
The required next term in the sequence is 35,185.
What is inductive reasoning?Inductive reasoning is defined as, tempting judgments by moving from the details to the fact. It's usually determined with inferential reasoning, where you move from known information to precise conclusions.

Step-by-step explanation:
Define the variables:
Let x be the money invested in the account that gained 10%.Let y be the money invested in the account that lost 4%.Given information:
$28,500 = total amount invested between the two accounts$1,310.00 = total amount gainedPercentages in decimal form:
10% = 0.14% = 0.04Create a system of equations using the given information and defined variables:
[tex]\begin{cases}x + y = 28500\\0.1x - 0.04y = 1310 \end{cases}[/tex]
Rewrite Equation 1 to make y the subject:
[tex]\implies y=28500-x[/tex]
