The length of AD is approximately 17.021 units.In a right triangle ABC with altitude BD drawn to hypotenuse AC, we are given that BD = 15 and DC = 45. We need to find the length of AD.
Since BD is the altitude, it divides the right triangle into two smaller triangles: ABD and CBD.
Using the properties of similar triangles, we can set up the following proportion:
AD/AB = DC/BC
Plugging in the given values, we have:
AD/AB = 45/60
Simplifying the proportion, we get:
AD/AB = 3/4
We can rewrite this equation as:
AD = (3/4) * AB
Now, let's consider triangle ABD. It is a right triangle, and we know that BD = 15.
Using the Pythagorean theorem, we have:
AB^2 = AD^2 + BD^2
Substituting the value of BD, we get:
AB^2 = AD^2 + 15^2
Since we want to find the length of AD, we rearrange the equation as:
AD^2 = AB^2 - 15^2
Substituting the value of AD from our previous equation, we have:
(3/4)^2 * AB^2 = AB^2 - 225
Expanding and simplifying, we get:
9/16 * AB^2 = AB^2 - 225
Cross-multiplying and rearranging, we have:
7 * AB^2 = 3600
Dividing both sides by 7, we find:
AB^2 = 514.2857
Taking the square root of both sides, we get:
AB ≈ 22.695
Finally, substituting this value back into our equation for AD, we have:
AD ≈ (3/4) * 22.695
AD ≈ 17.021
Therefore, the length of AD is approximately 17.021 units.

Fancy Pineapple produces pineapple juice and canned pineapple rings. This year the company anticipates a demand of at least 36,000 pints of pineapple juice and 3,600 cans of pineapple rings. Each pint of pineapple juice requires 2 pineapples, and each can of pineapple rings requires 1 pineapple. The company anticipates using at least 72,000 pineapples for these products. Each pint of pineapple juice costs the company 16¢ to produce, and each can of pineapple rings costs 40¢ to produce. How many pints of pineapple juice and cans of pineapple rings should Fancy Pineapple produce to meet the demand and minimize total costs?
To meet the demand and minimize total costs, Fancy Pineapple should produce 18,000 pints of pineapple juice and 3,600 cans of pineapple rings.
By producing this quantity, the company can meet the demand for 36,000 pints of pineapple juice and 3,600 cans of pineapple rings while using the minimum number of pineapples and minimizing costs.
To determine the optimal production quantity, we need to consider the requirements for each product and the costs associated with production.
Since each pint of pineapple juice requires 2 pineapples and each can of pineapple rings requires 1 pineapple, the total number of pineapples needed for both products is 39,600 (36,000 pints + 3,600 cans).
Given that the company anticipates using at least 72,000 pineapples, this quantity is sufficient to meet the demand.
Next, we consider the costs. Each pint of pineapple juice costs 16¢ to produce, while each can of pineapple rings costs 40¢ to produce. To minimize costs, the company should produce the product with the lower cost per unit.
In this case, producing pineapple juice is more cost-effective as it costs 16¢ per pint compared to 40¢ per can of pineapple rings. Therefore, Fancy Pineapple should produce 18,000 pints of pineapple juice to meet the demand.
In summary, Fancy Pineapple should produce 18,000 pints of pineapple juice and 3,600 cans of pineapple rings to meet the demand for 36,000 pints of pineapple juice and 3,600 cans of pineapple rings while minimizing costs.
This production quantity ensures the optimal use of pineapples and takes into account the lower production cost per unit for pineapple juice compared to pineapple rings.

There is more dispersion relative to the mean in the distribution of GPA compared to the distribution of age of the students.
The coefficient of variation (CV) is a measure of relative dispersion, which compares the standard deviation to the mean of a dataset. A higher CV indicates greater dispersion relative to the mean, while a lower CV indicates less dispersion.
If the distribution of GPA has a higher coefficient of variation compared to the distribution of age, it means that there is more dispersion relative to the mean in the GPA distribution. This suggests that there is greater variation or diversity in GPA scores among the students compared to their ages. In contrast, if the distribution of GPA had a lower coefficient of variation compared to the distribution of age, it would indicate less dispersion relative to the mean in the GPA distribution, implying less variation or more uniformity in GPA scores.

What is the proportional relationship of y=5/6, x=3/4
Proportional relationships refer to the relationship between two variables in which their ratio always remains constant. In the given case, we have two variables, y and x, and their respective ratios y = 5/6 and x = 3/4.
Therefore, we can determine their proportional relationship as follows:
$$y : x = \frac{5}{6} : \frac{3}{4} = \frac{5}{6} \cdot \frac{4}{3} = \frac{20}{18} = \frac{10}{9}$$
This implies that for every 10 units of y, there are 9 units of x, and their ratio remains constant throughout.
Hence, we can say that y and x have a proportional relationship with a constant ratio of 10:9.
The proportional relationship between two variables is a special type of linear relationship that describes how the variables are related to one another. It is a type of relationship in which the ratio of the two variables remains constant. In other words, as one variable increases or decreases, the other variable changes in proportion to maintain a constant ratio. For example, the relationship between distance and time is a proportional relationship because the ratio of distance to time is always constant. In this case, the constant ratio is the speed of the object traveling the distance over a given time interval.
In the given problem, the variables y and x have a proportional relationship, and their ratio is constant at 10:9. This means that for every 10 units of y, there are 9 units of x, and the ratio remains constant regardless of the values of y and x. This is because the values of y and x are in the same proportion as their respective numerators and denominators. Therefore, we can conclude that y and x have a proportional relationship with a constant ratio of 10:9.
Proportional relationships describe the relationship between two variables in which their ratio always remains constant. In this case, we have two variables, y and x, and their respective ratios y = 5/6 and x = 3/4. We found that y and x have a proportional relationship with a constant ratio of 10:9. This implies that for every 10 units of y, there are 9 units of x, and the ratio remains constant regardless of the values of y and x.

How long will it take me to travel a distance of 12 km at the average rate of 5m/s
To find out how long it will take to travel a distance of 12 km at an average rate of 5 m/s, we can use the formula for speed:
Speed = Distance / Time
Rearranging the formula to solve for time, we have:
Time = Distance / Speed
Substituting the values, we have:
Time = 12 km / 5 m/s
To perform the calculation, we need to convert the distance to meters since the speed is given in meters per second. There are 1000 meters in 1 kilometer, so 12 km is equal to 12,000 meters.
Now, we can substitute the values into the formula:
Time = 12,000 meters / 5 m/s
Dividing 12,000 by 5, we get:
Time = 2400 seconds
Therefore, it will take approximately 2400 seconds to travel a distance of 12 km at an average rate of 5 m/s.

The water slides have 37 temporary employees and 37 permanent employees. What percentage of the employees at the water slides are temporary?
At the water slides, there are a total of 37 temporary employees and 37 permanent employees. To determine the percentage of employees who are temporary, 50% of the employees at the water slides are temporary employees.
The total number of employees at the water slides is the sum of temporary and permanent employees: 37 temporary + 37 permanent = 74 employees.
To find the percentage of temporary employees, we divide the number of temporary employees by the total number of employees and multiply by 100:
Percentage of temporary employees = (Number of temporary employees / Total number of employees) * 100
Plugging in the values:
Percentage of temporary employees = (37 / 74) * 100

Solve g^-1(x)=5x
Can anyone work out part b pls?
To solve the equation g^(-1)(x) = 5x, we need to find the inverse function of g and then substitute it into the equation. The inverse function of g, denoted as g^(-1), can be found by interchanging the roles of x and y in the original function g(x). Once we have the inverse function, we substitute it into the equation and solve for x.
Let's denote the inverse function of g(x) as g^(-1)(x). To find g^(-1)(x), we interchange the roles of x and y in the original function g(x), so g^(-1)(x) = y.
Next, we substitute y into the equation g^(-1)(x) = 5x, which gives us y = 5x. Now, we replace y with g^(-1)(x), resulting in g^(-1)(x) = 5x.
To solve for x, we need to isolate x. We can do this by applying the inverse operation to both sides of the equation. Dividing both sides by 5, we obtain g^(-1)(x) / 5 = x.
Therefore, the solution to the equation g^(-1)(x) = 5x is x = g^(-1)(x) / 5.

Are these ratios equivalent? Explain why or why not.
The ratios of the number of boys to girls in ninth grade (4:5) and the number of apples to pears sold at the farmers market (12:15) are equivalent because we were able to convert 4:5 into 12:15 by multiplying both terms by 3.
Ratios equivalent:
When two ratios have the same value, they are equivalent ratios. To verify that two ratios are equivalent, you may cross-multiply and reduce the resulting fractions. In the ninth grade, there are 4 boys for every 5 girls. 4:5 is the ratio of boys to girls. Similarly, 12 apples are sold for every 15 pears at the farmers' market. 12:15 is the ratio of apples to pears, and we need to decide whether this ratio is equivalent to 4:5 or not.Let's convert the ratio 4:5 to its equivalent ratio 12:15 by multiplying both terms by 3, which gives us 12:15. Since 12:15 is the same as 12:15, the two ratios are equivalent.

Two cyclists meet at the library and then go for a bike ride.
The distance each person has traveled from her home at x
hours from the start of the ride is linear, as shown.
Which statement must be true?
Two cyclists meet at the library and then go for a bike ride. The distance each person has traveled from her home at x hours from the start of the ride is linear, as shown.
Let's assume that cyclist A and B start at a distance x and y, respectively, from the library. Further, let's assume that cyclist A starts at t = 0. Then, the distance from the library for cyclist A at t hours after the start of the ride is represented by x + rt. The distance from the library for cyclist B at t hours after the start of the ride is represented by y + st.As the question says, the distance each person has traveled from her home at x hours from the start of the ride is linear. Thus, we can write their distances from the library as:dA(x) = x + rtdB(x) = y + st, where dA and dB represent the distance covered by cyclists A and B respectively.Now, if we want to find out the distance between the two cyclists at x hours after the start of the ride, we can use the following formula:distance between the two cyclists = dB(x) - dA(x)= (y + st) - (x + rt) = (y - x) + (s - r)tSince s and r are constants, the expression (y - x) + (s - r)t is linear with respect to t. Hence, the statement "The distance between the two cyclists is a linear function of x" must be true.

The carpet Zac selected sells for $2.40 a square foot. How much will it cost Zac to carpet the entrance and hallway of his house?
The entrance measures 6 feet wide and 8 feet long, and the hallway is 3 feet wide and 14 feet long. We need to calculate the area of both and then multiply by $2.40. We can do that as follows:
Entrance area = 6 feet x 8 feet
= 48 square feet
Hallway area = 3 feet x 14 feet
= 42 square feet
Total area = 48 + 42
= 90 square feet
The cost of the carpet, we can multiply the total area by the cost per square foot: $2.40/square foot x 90 square feet = $216.00
It will cost Zac $216.00 to carpet the entrance and hallway of his house if he selects the carpet that sells for $2.40 a square foot.

The right triangle shown below is formed by joining three squares at their vertices. What
is the value of z, the side length of the bottom square?
We find: z = x Therefore, the value of z, the side length of the bottom square, is equal to the side length of the top square.
Let's assume the side length of the top square is x. Since the right triangle is formed by joining the squares at their vertices, the hypotenuse of the triangle is the diagonal of the top square.
In a square, the length of the diagonal is equal to the side length multiplied by the square root of 2. Therefore, the hypotenuse of the right triangle is x * √2.
The two legs of the right triangle are the side lengths of the squares adjacent to the hypotenuse. In this case, one leg is z, the side length of the bottom square.
Using the Pythagorean theorem, we have the equation:
z^2 + z^2 = (x * √2)^2
Simplifying the equation, we get:
2z^2 = 2x^2
Dividing both sides by 2, we have:
z^2 = x^2
Taking the square root of both sides, we find:
z = x
Therefore, the value of z, the side length of the bottom square, is equal to the side length of the top square.

averi bought a 6 ounce can of pecans for 4.89 . what was the unit price
The unit price of the pecans is $0.815 per ounce (rounded to three decimal places).
To calculate the unit price, we divide the total cost of the item by the quantity purchased. In this case, Averi bought a 6-ounce can of pecans for $4.89.
To find the unit price, we divide the total cost ($4.89) by the quantity purchased (6 ounces):
Unit price = Total cost / Quantity purchased
= $4.89 / 6 ounces
To simplify the unit price, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4.89 and 6 is 3.
Dividing both the numerator and denominator by 3, we get: Unit price = ($4.89 / 3) / (6 ounces / 3)
= $1.63 / 2 ounces
Therefore, the unit price of the pecans is $0.815 per ounce (rounded to three decimal places). This means that Averi paid approximately $0.815 for each ounce of pecans she purchased.
