The sides of a square field are 12 meters. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to a side of the field. How far does the sprinkler travel in 2 revolutions? How much of the field is not reached by the sprinkler? Round your answer to the nearest hundredth.
Answers
There are 30.90 meters squared of the field is not reached by the sprinkler.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
First, get the area of the square field. The area of the square is side multiplied by side.
A = S x S
A = 12 X 12
A = 144 meters squared
Second, get the area of the circle formed by the sprinkler.
The circle is formed inside the square with a radius of 6 meters (half of the diameter which is 12 meters).
A = πr²
A = 3.1415 x 6²
A = 113.09733 meters squared.
In order to get the not sprinkled area, subtract the area of the square by the area of the circle.
Hence, Not Sprinkled Area = 144 meters squared - 113.09733 meters squared
Thus, The final answer is 30.90 meters squared.

Answer:
g
g
Answers
The quantity of butter that should be used is 120g. ii. The total quantity of flapjacks would be: 540g. b. The amount of oats would be: 75g.
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given that the ratio of ingredients for the recipe is 1: 2: 2: 4.
Let us suppose the syrup has a ratio of 1x, then the ratio of other ingredients are:
sugar = 2x
butter = 2x
oats = 4x
a. Tiger uses syrup, x = 60g
i. The quantity of butter that should be used is 2x = 2(60) = 120g.
ii. The total quantity of flapjacks would be:
x + 2x + 2x + 4x = 60 + 120 + 120 + 240 = 540g
b. Given that:
150g syrup = 8 flapjacks
x = 1 flapjack
Using the cross multiplication method, we have:
x = 150/8
x = 18.75g
So, for one flap jack the syrup needed is 18.75g, then the amount of oats would be: 4x = 4(18.75) = 75g.
Hence, the quantity of butter that should be used is 120g. ii. The total quantity of flapjacks would be: 540g. b. The amount of oats would be: 75g.

How many tourists only visited the LEGOLAND (of these three)?
Answers
44 tourists only visited LEGOLAND (of these three).
Solving for the tourists only visited the LEGOLAND only:Let's call the number of tourists who visited only LEGOLAND x.
From the information given, we know that:
258 tourists had visited the Magic Kingdom
299 tourists had visited Universal Studios
100 tourists had visited both the Magic Kingdom and LEGOLAND
82 tourists had visited both the Magic Kingdom and Universal Studios
76 tourists had visited both LEGOLAND and Universal Studios
12 tourists had visited all three theme parks
68 tourists did not visit any of these theme parks
We can calculate x as follows:
x = number of tourists who visited LEGOLAND only
number of tourists who visited LEGOLAND - number of tourists who visited LEGOLAND and Magic Kingdom - number of tourists who visited LEGOLAND and Universal Studios + number of tourists who visited all three parks
= 100 - 82 - 76 + 12
= 44

Can someone solve this with the work also shown?
Answers
Answer:
a.
The growth rate (k) can be calculated using the exponential growth formula: P = P0 * e^(kt), where P0 is the initial population, t is the time in years, and e is the natural logarithm base.
From the information provided, the initial population of elves in 2000 was 23, and in 2003, the population was 34. By substituting the values into the formula and solving for k, we get:
34 = 23 * e^(k * 3)
Taking the natural logarithm of both sides:
ln(34) = ln(23 * e^(k * 3))
Using the logarithmic identity:
ln(34) = ln(23) + ln(e^(k * 3))
Solving for k:
k = (ln(34) - ln(23)) / (3) = 0.175
Therefore, the growth rate (k) for the population of elves is 0.175.
b.
To find the population of elves in 2020, we can use the exponential growth formula:
P = P0 * e^(kt)
Substituting the initial population of elves in 2000, which was 23, and the growth rate (k), which we found to be 0.175, we get:
P = 23 * e^(0.175 * 20)
Calculating the exponential function:
P = 23 * e^3.5
Therefore, there will be approximately 51 elves in 2020.
c.
To find the year when there will be 543 elves, we can use the exponential growth formula and solve for t:
543 = 23 * e^(0.175 * t)
Dividing both sides by 23 and taking the natural logarithm of both sides:
ln(543/23) = 0.175 * t
Solving for t:
t = (ln(543/23)) / 0.175
Therefore, there will be 543 elves in the year 2027.

Reid found 6 coins that totaled 61c in all. What coins did the find?
Answers
Reid found 1 quarter, 3 dimes, 1 nickel and 1 penny coins.
What is currency?Currency is anything that is generally accepted to have value as a medium of exchange so that it can be traded for goods and services.
Given that, Reid found 6 coins that totaled 61 cents in all.
Since, in total he got 6 coins that value 61 cents in total.
So, wd know that,
1 quarter = 25 cents
1 dime = 10 cents
1 nickel = 5 cents
1 penny = 1 cents,
Adding them = 25 + 10 + 5 + 1
= 41 cents
We need 20 cents and 2 coins more,
So, add 3 coins more in nickel, so, that,
3 nickels = 30 cents
Now, Reid in total will have 6 coins and that will value 61 c.

What do you mean by Probability?Probability is a branch of mathematics that deals with the study of random events and their likelihood of occurring. It provides a framework for understanding the uncertainty and unpredictability of real-world events and helps to make informed decisions based on data and evidence.
The basic concept of probability is the idea that every event has a numerical value between 0 and 1, representing the likelihood of the event occurring. An event with a probability of 1 is considered certain to occur, while an event with a probability of 0 is considered impossible to occur. Events with probabilities between 0 and 1 are considered uncertain, and their likelihood of occurrence can be described using a probability distribution.
There are different methods for calculating probabilities, including classical probability, which assumes that all outcomes are equally likely, and empirical probability, which is based on actual observations of real-world events. The concept of conditional probability is also important, as it allows us to calculate the likelihood of an event occurring given the occurrence of another event.
Probability is widely used in many different fields, including science, engineering, finance, and medicine. In science, it is used to model and understand complex systems, while in engineering it is used to design and test new technologies. In finance, it is used to evaluate investments and make informed decisions, while in medicine it is used to assess the risk of diseases and evaluate the effectiveness of treatments.

4. The sum of the first eight terms of an arithmetic sequence is 60. The sum of the 9th to 14th terms is 108. Find the 25th term.
Answers
Answer:
PLACEHOLDER SRRY BRB
Step-by-step explanation:
The formula for the sum of the first n terms of an arithmetic sequence is: Sn = n/2(2a + (n-1)d).
Using this formula, we can find the value of d:
For the first eight terms:
8/2(2a + (8-1)d) = 60
Solving for d:
d = (60 - 2a) / 14
For the next six terms:
6/2(2a + (9-1)d) = 108
Solving for a:
a = (108 - 6d) / 10
Now that we have the values of a and d, we can find the 25th term using the formula for the nth term of an arithmetic sequence: an = a + (n-1)d.
an = a + (25-1)d = a + 24d
Plugging in the values of a and d found above, we get the 25th term:
an = (108 - 6d) / 10 + 24 [(60 - 2a) / 14] = (108 - 6d) / 10 + 24 [(60 - 2(108 - 6d) / 10) / 14]
Simplifying further, we can find the 25th term

Answers
Answer:
student tickets cost $4.50
adult tickets cost $7.00
Step-by-step explanation:
a = cost of an adult ticket
s = cost of a student ticket
(1) 68a + 136s = 1088
(2) 79a + 140s = 1183
solve (1) for a:
68a = 1088 - 136s
a = 16 - 2s substitute this into (2):
79(16-2s) + 140s = 1183
1264 - 158s + 140s = 1183 solve for s:
-18s = -81
s = -81/-18 = 4.50 plug this into either equation 1 or 2 to solve for a:
68a + 136(4.50) = 1088
68a = 1088 - 612 = 476
