Flagpole
shadow
40 ft
The diagram above shows a 40-foot flagpole and its shadow in relation to a nearby building that is
324 feet tall. If the flagpole's shadow is 50% longer than the flagpole itself, how far is the
building from the flagpole?
The distance between the flagpole and the building is the number of feet between them
The building is 162 feet from the flagpole
How to determine the distanceThe given parameters are:
Flagpole = 40 feetBuilding Shadow = 324 feetThe flagpole's shadow is 50% longer than the flagpole.
So, the length (l) of the flagpole's shadow is:
\(l = 40 * (1 + 50\%)\)
\(l = 60\)
The length of the building's shadow (d) is then calculated as:
\(60 : 40 =d : 324\)
Express as fraction
\(\frac{60}{40}= \frac{d}{324}\)
\(1.50 = \frac{d}{324}\)
Solve for d
\(d = 1.50 * 324\)
\(d = 486\)
The distance (x) of the building from the flagpole is then calculated as:
\(x = 486 - 324\)
\(x = 162\)
Hence, the building is 162 feet from the flagpole

Suppose the results indicate that the null hypothesis should not be rejected; thus, it is possible that a type II error has been committed. Given the type of error made in this situation, what could researchers do to reduce the risk of this error? Choose a 0.01 significance level, instead of a 0.05 significance level. Increase the sample size.
Answer:
Increase the sample size.
Step-by-step explanation:
Increasing the sample size is the best way to reduce the likelihood of a type II error.
The type II error occurs when a hypothesis test accepts a false null hypothesis. That is, it fails to reject the null hypothesis that is false.
In such a situation, to increase the power of the test, you have to increase the sample size used in the test. The sampling size has the ability to detect the differences in a hypothesis test.
We have a bigger chance of capturing the difference if the sample size is larger, and it also increases the power of the test.
The graph below shows the average cost of renting a studio apartment in one city in each of the years 2002 through 2006. By what percentage does the average price increase from 2002 to 2003? Obtain a second version of the graph by sliding a piece of paper over the bottom of the graph so that the bars start at 300. In this new graph, by what percentage does the price appear to increase from 2002 to 2003?
In the new graph, the price appears that is increase from 2002 to 2003 is 25% and 100%. Hence, option A is correct.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from.
Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the data mentioned in the question,
Average cost to rent studio in 2002 = 400 and,
Average cost to rent studio in 2003 = 500
Then percent increase from year 2002 to 2003 will be,
% increase = (500 - 400)/400 × 100
% increase = 25%
Then, % increase from 2002 to 2003 is 25%,
(200 - 100)/100 × 100 = 100%.

What is the percent of 1 - 3√(5/35) ?
Answer:
1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755
0.0755 * 100 = 7.55%
Step-by-step explanation:
To find the percentage of 1 - 3√(5/35), we need to first evaluate the expression.
1 - 3√(5/35) = 1 - 3√(1/7) = 1 - 3*(1/sqrt(7)) ≈ 0.0755
To convert this decimal to a percentage, we simply multiply by 100:

Find the 36th term.
5, 8, 11, 14, 17, ...
36th term = [?
Answer:
110
Step-by-step explanation:
nth term = 3n + 2
3 (36) + 2
108 + 2 = 110
Answer:
The 36th term in the sequence is 104.
Here's how to find it:
- Start with the first number in the sequence: 5.
- Add the common difference, which is 3, to get the second number in the sequence: 8.
- Add the common difference to the second number to get the third number: 11.
- Continue adding the common difference to each subsequent number to find the next term in the sequence.
- The 36th term is three less than 37 times the common difference added to the first term.
- Using that formula, we can calculate the 36th term as: 5 + (36 - 1) * 3 = 5 + 105 = 110.
- Therefore, the 36th term in the sequence is 104.

Find the number of ways 66 identical coins can be separated into three nonempty piles so that there are fewer coins in the first pile than in the second pile and fewer coins in the second pile than in the third pile.
There are 331 ways when 66 identical coins can be separated into three nonempty piles
Let the piles have a, b and c coins, with 0<a <b <c. Then, let b=a+k₁, and
c=b+k₂, such that each ki≥1.
The sum is then a+a+k₁+a+k₁+k₂= 66 ⇒ 3a+2k₁+k₂ = 66.
This is simply the number of positive solutions to the equation
3x+2y+z = 66.
If a = 1, then 2k₁ + k₂ = 63⇒ 1≤k₁ ≤31. Each value of k₁ corresponds to a unique value of k₂, so there are 31 solutions in this case.
Similarly, if a = 2, then 2k₁+k₂= 60⇒ 1≤k₁ ≤29, for a total of 29 solutions in this case.
If a = 3, then 2k₁+ k₁= 57 ⇒ 1 ≤ k₁ ≤28, for a total of 28 solutions.
In general, the number of solutions is just all the numbers that aren't a multiple of 3, that are less than or equal to 31.
We then add our cases to get
=1+2+4+....31=1+2+3+...31-3(1+2+3+...10)

Emily's score for a Mathematics test was 5% higher than her score for an English test. If Emily scored 84 points for the Mathematics test, how many points did she score for the English test?
Answer:
80 points
Step-by-step explanation:
If score in English is x points and score in math is 5% higher then score in math
y = x + 0.05x
where 0.05 = 5% expressed as decimal
0.05x refers to the 5% increase in score
y = math score
y = x(1 + 0.05)
y = 1.05x
Given score in math = 84 this becomes
84 = 1.05x
x = 84/1.05
x = 80
So Emily's score in English was 80 points

102.5 degrees Fahrenheit. How much
medicine would be usual dose for a 18

milligrams
Round your answer to the nearest milligram.
Answer: The usual dose for an 18-month-old weighing 21 pounds is 48 mg of ibuprofen.
Step-by-step explanation: To find the usual dose of ibuprofen for a child, we need to follow these steps:
Convert the child’s weight from pounds to kilograms. One pound is equal to 0.4536 kilograms, so we multiply 21 by 0.4536 to get 9.5256 kilograms.Multiply the child’s weight in kilograms by the dose per kilogram. The dose per kilogram is 5 mg when the fever is under 102.5 degrees Fahrenheit, so we multiply 9.5256 by 5 to get 47.628 mg.Round the result to the nearest milligram. To round a number to the nearest milligram, we look at the digit after the decimal point. If it is 5 or more, we add one to the digit before the decimal point and drop the rest. If it is less than 5, we keep the digit before the decimal point and drop the rest. In this case, the digit after the decimal point is 6, which is more than 5, so we add one to the digit before the decimal point and drop the rest. The result is 48 mg.Therefore, the usual dose for an 18-month-old weighing 21 pounds is 48 mg of ibuprofen. Hope this helps, and have a great day! =)

Brooklyn is going to invest in an account paying an interest rate of 3.5% compounded continuously. How much would Brooklyn need to invest, to the nearest ten dollars, for the value of the account to reach $64o in 9 years?
Brooklyn needs to invest $432.43, rounded to the nearest ten dollars.
To determine how much Brooklyn needs to invest in an account that pays a continuously compounded interest rate, we can use the formula:
A = \(Pe^(^r^t^)\)
where A is the future value of the account, P is the principal investment, e is the mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time in years.
In this case, we want the future value of the account to be $640, the interest rate is 3.5% (or 0.035 as a decimal), and the time is 9 years. We can substitute these values into the formula and solve for P:
640 = \(Pe^(^0^.^0^3^5^*^9^)\)
640 = Pe^0.315
P =\(640/e^0^.^3^1^5\)
P = 432.43
Therefore, to have a future value of $640 in 9 years with a continuously compounded interest rate of 3.5%.

The class must seat 40 students along with the teacher's table and shelves, which occupy 350m2. How much space will each student occupy? (Show how you drive at your answer)
The amount of space each student will occupy is 0.25 square meters of space in the classroom.
How to calculate the space each student will occupyTo find the amount of space each student will occupy,
We need to first subtract the area taken up by the teacher's table and shelves from the total area of the classroom.
Then we can divide the remaining area by the number of students.
Let's say the total area of the classroom is A.
Then we have:
A - 350 ( the area available for students)
If each student occupies an area of x, then we have:
40x = A - 350
Substituting the first equation into the second equation, we get:
40x = (A - 350)
We can solve for x by dividing both sides by 40:
x = (A - 350) / 40
We know that there are 40 students, so we can substitute that into the equation:
x = (A - 350) / 40 = (360 - 350) / 40 = 0.25
Therefore, each student will occupy 0.25 square meters of space in the classroom.
