Two similar regular hexagons have a common center. If each side of the big hexagon is twice the side of the small one and the area of the small hexagon is 3 sq. in, what is the area of the big hexagon?
The area of the larger square is 4 times larger than the area of the smaller square. The area of the big hexagon is 12 sq. in.
Explanation:The area of the larger square is 4 times larger than the area of the smaller square. This is because the area of a square is proportional to the square of its side length.
In this case, the side length of the larger square is twice the side length of the smaller square, so the area of the larger square is 2² times greater than the area of the smaller square.
Given that the area of the small hexagon is 3 sq. in, the area of the big hexagon can be found by multiplying the area of the small hexagon by the square of the scale factor:
Area of big hexagon = (scale factor)² * Area of small hexagon = 2² * 3 sq. in = 12 sq. in
If your monthly net (after-tax) income is $1,500, what should be your maximum amount spent on credit payments? A. $200 B. $300 C. $400 D. $500
According to budgeting guidelines often referred to as the 20/30/50 rule, no more than 20% of your net income should be spent on debt repayments. Therefore, the maximum amount spent on credit payments for a $1,500 monthly income should be $300.
Explanation:The best practice for budgeting recommends that no more than 20% of your net monthly income should be spent on debt repayments, including credit payments. This is commonly referred to as the 20/30/50 rule. Therefore, given a monthly net income of $1,500, the maximum amount spent on credit payments should be 20% of $1,500, which equals to $300.
Here's how you would calculate it:
Convert 20% to decimal form by dividing it by 100. 20/100 = 0.2.Multiply the decimal by your net income to get your maximum spend on credit payments. 0.2 x $1,500 = $300.So, the correct answer is B. $300.

Find the particular solution of the differential equation dydx+ycos(x)=5cos(x) satisfying the initial condition y(0)=7.
The provided differential equation is a first-order linear differential equation, which can be solved using an integrating factor. After solving, the particular solution satisfying the initial condition y(0)=7 is y=e^(-sin(x))(5sin(x)+7).
Explanation:The differential equation provided is a first-order linear differential equation, which can be solved using an integrating factor. In this case, dy/dx + ycos(x) = 5cos(x), the integrating factor is e^(∫ cos(x) dx) = e^sin(x). Multiplying everything by the integrating factor, we get (ye^sinx)' = 5cos(x)e^sin(x).
Then we can integrate on both sides to get ye^sin(x) = 5sin(x) + C, where C is the constant of integration. To find the particular solution, we can use the initial condition y(0)=7. By substituting these values, we can solve for C. Substituting x=0 and y=7 yields C=7. Thus, the particular solution is y=e^(-sin(x))(5sin(x)+7).

A water well is to be drilled in the desert where the soil is either rock, clay or sand. The probability of rock P(R)equals=0.53. The clay probability is P(C)equals=0.21. The sand probability is P(S)equals=0.26. If the soil is rock, a geological test gives a positive result with 35% accuracy. If it is clay, this test gives a positive result with 48% accuracy. The test gives a 75% accuracy for sand.
Given the test is positive, what is the probability that the soil is clay, P(clay | positive)? Use Bayes' rule to find the indicated probability.
To find the probability of the soil being clay given a positive test result, we can use Bayes' rule. Given the probabilities of the different types of soil and the accuracy of the test in each soil type, we can calculate the probability using the law of total probability and Bayes' rule.
Explanation:To find the probability of the soil being clay given a positive test result, we can use Bayes' rule. Bayes' rule states that P(A|B) = (P(B|A) * P(A)) / P(B), where P(A|B) is the probability of event A happening given that event B has occurred, P(B|A) is the probability of event B happening given that event A has occurred, P(A) is the probability of event A happening, and P(B) is the probability of event B happening. In this case, event A is that the soil is clay and event B is that the test result is positive.
Given that the soil is clay, the test gives a positive result with 48% accuracy. Therefore, P(B|A) = 0.48. The probability of the soil being clay is P(A) = 0.21. To find P(B), we need to consider the probabilities of the test result being positive in each type of soil.
If the soil is rock, the test gives a positive result with 35% accuracy, so the probability of the test result being positive in rock soil is P(B|rock) = 0.35. Similarly, if the soil is sand, the test gives a positive result with 75% accuracy, so the probability of the test result being positive in sand soil is P(B|sand) = 0.75. We can calculate P(B) using the law of total probability: P(B) = P(B|rock) * P(rock) + P(B|clay) * P(clay) + P(B|sand) * P(sand).
Plugging in the given values, we have P(B) = 0.35 * 0.53 + 0.48 * 0.21 + 0.75 * 0.26. Now we can substitute the values into Bayes' rule:
P(clay | positive) = (P(positive | clay) * P(clay)) / P(positive) = (0.48 * 0.21) / P(B).
So the probability that the soil is clay given a positive test result is (0.48 * 0.21) / P(B).

Answer:
The equation of line is [tex]y=\frac{1}{2}(x)+1[/tex].
Step-by-step explanation:
Given information: The line passes through the point (4,3) and (2,2).
If a line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the point (4,3) and (2,2), so the equation of line is
[tex]y-3=\frac{2-3}{2-4}(x-4)[/tex]
[tex]y-3=\frac{-1}{-2}(x-4)[/tex]
[tex]y-3=\frac{1}{2}(x-4)[/tex]
Using distributive property, we get
[tex]y-3=\frac{1}{2}(x)+\frac{1}{2}(-4)[/tex]
[tex]y-3=\frac{1}{2}(x)-2[/tex]
Add 3 on both sides.

On a busy day you clock into work at 6:45 a.m .You clock out for lunch at 12:30 p.m how long did you work before lunch
The student worked for 5 hours and 45 minutes before taking a lunch break, calculated by finding the difference between the clock-in time of 6:45 a.m. and the lunchtime of 12:30 p.m.
Explanation:The student worked for a certain number of hours before taking a lunch break. To calculate the duration of work before lunch, we subtract the start time from the end time. The student clocks in at 6:45 a.m. and clocks out at 12:30 p.m. for lunch.
First, we convert the time worked to a 24-hour format: 6:45 a.m. remains the same but 12:30 p.m. is 12:30 in 24-hour time. Now, we calculate the time difference:
From 6:45 a.m. to 7:45 a.m. is 1 hour.7:45 a.m. to 12:30 p.m. is 4 hours and 45 minutes.Adding up the hours and minutes, we get a total of 5 hours and 45 minutes worked before lunch.

The sales tax for an item was $22.50 and it cost $450 before tax. Find the sales tax rate. Write your answer as a percentage.
Final answer:
The sales tax rate is found by dividing the amount of sales tax by the cost of the item before tax and then multiplying by 100. In this case, the sales tax rate is 5%.
Explanation:
To find the sales tax rate of an item, you need the amount of sales tax paid and the cost of the item before tax. The formula to calculate the sales tax rate is:
sales tax rate = (amount of sales tax \/ cost of the item before tax) \ 100
Applying the formula, we have:
sales tax rate = ($22.50 \/ $450) \ 100
sales tax rate = 0.05 \ 100
sales tax rate = 5%
Therefore, the sales tax rate for the item is 5%.
The t value for a 99% confidence interval estimation based upon a sample of size 10 is
The [tex]\( t \)[/tex]-value for a 99% confidence interval based on a sample size of 10 is 3.2498.
To find the [tex]\( t \)[/tex]-value for a 99% confidence interval estimation based on a sample size of 10, we need to use the [tex]\( t \)[/tex]-distribution table or a calculator. The [tex]\( t \)[/tex]-distribution is used when the sample size is small (typically [tex]\( n < 30 \)[/tex]) and the population standard deviation is unknown.
Given:
- Confidence level: 99%
- Sample size [tex](\( n \)): 10[/tex]
The degrees of freedom [tex](\( df \))[/tex] are calculated as:
[tex]\[ df = n - 1 = 10 - 1 = 9 \][/tex]
To find the critical [tex]\( t \)[/tex]-value for a 99% confidence interval with 9 degrees of freedom, we look for the [tex]\( t \)[/tex]-value that corresponds to the area in the tails of the distribution. For a 99% confidence interval, the area in each tail is:
[tex]\[ \frac{1 - 0.99}{2} = 0.005 \][/tex]
So we need the [tex]\( t \)[/tex]-value such that 0.5% of the distribution is in each tail.
Using a [tex]\( t \)[/tex]-distribution table or a calculator, we find the [tex]\( t \)[/tex]-value for 9 degrees of freedom and a 99% confidence interval (or 0.5% in each tail).
The [tex]\( t \)[/tex]-value for 9 degrees of freedom at the 99% confidence level is approximately:
[tex]\[ t_{0.005, 9} \approx 3.2498 \][/tex]
Thus, the [tex]\( t \)[/tex]-value for a 99% confidence interval based on a sample size of 10 is approximately 3.2498.
A cylinder has a diameter of 14 cm and a height of 20 cm.
a. Find the total surface area of the cylinder.
b. If gift wrap cost $3 per square centimeter, how much will it cost to cover the cylinder with gift wrap? Use 3.14 for π.
c. Find the volume of the cylinder.
The total surface area of the cylinder is approximately 1187.72 cm², the volume is approximately 3077.2 cm³, and the cost to cover it with gift wrap at $3 per square centimeter is $3,558.76.
Finding the Surface Area and Volume of a CylinderThe surface area of a cylinder is calculated using the formula: Surface Area = 2πr(height) + 2πr². With a diameter of 14 cm, the radius (r) is half of that, which is 7 cm. Plugging in the values, the surface area is 2π(7 cm)(20 cm) + 2π(7 cm)².
For part b, once we have calculated the surface area, we can determine the cost to cover the cylinder using the given price per square centimeter. If S represents the total surface area, the cost will be $3 times S.
The volume of the cylinder can be found with the formula V = πr²h, and using the radius of 7 cm and a height of 20 cm, we get the volume V = π(7 cm)²(20 cm).
Performing these calculations:
Surface Area = 2π(7 cm)(20 cm) + 2π(7 cm)² = 2π(7 cm)(20 cm) + 2π(49 cm²) = 2π(140 cm²) + 2π(49 cm²) = 280π cm² + 98π cm² = 378π cm².Volume = π(7 cm)²(20 cm) = π49 cm²20 cm = 980π cm³.Cost = $3 × 378π cm² = $1134π.Using 3.14 for π, we get:
Surface Area = 378π cm² = 1187.72 cm² (approximately).Volume = 980π cm³ = 3077.2 cm³ (approximately).Cost = $1134π = $3,558.76 (approximately).In the triangle XYZ, IF WZ=24, then WY is:
