The given investment realized a loss of $3.75 with 31.25% decrease.
What is profit?The amount made by selling a product, which should be greater than the product's cost price, is generally referred to as the profit. It is the profit generated by all business activities. In other words, a product is deemed to have made a profit if its selling price (SP) exceeds its cost price (CP). It explains the financial gain realised when the revenue from a company activity outpaces the costs, like as taxes and expenses, involved in maintaining a business activity.
Given : Purchase Price: $12.00
Selling Price: $8.25
Since the purchase price is more than the selling prize, So the investment has been sold at a loss.
The loss on investment = Purchasing price - Selling price
= $ 12 - 8.25
= $3.75.
% of decrease = (loss/ purchasing price) × 100
= 3.75/12 × 100
= 31.25 %

The reading on a water meter in April and May are 417.8 kl and 430.4 kl. If there is a basic charge of 23 pesos and the cost per kl is 20 pesos, how much is the billing for water consumption between the two months?
Answer:
the billing for water consumption between April and May is 275 pesos.
Step-by-step explanation:
To find the billing for water consumption between April and May, we need to calculate the difference in the water usage as measured by the water meter.
The difference between the readings in April and May is:
430.4 kl - 417.8 kl = 12.6 kl
To calculate the cost of this water usage, we need to multiply the volume of water by the cost per kl and then add the basic charge.
The cost of the water usage is:
12.6 kl x 20 pesos/kl = 252 pesos
Adding the basic charge of 23 pesos, the total billing for water consumption between the two months is:
252 pesos + 23 pesos = 275 pesos
Therefore, the billing for water consumption between April and May is 275 pesos.

what is the median? 0, 5, 10, 10, 12, 15, 15, 20, 25 30, 30, 35, 35, 45, 60
Answer:
The median of the given data is 20. To find the median, arrange the data in numerical order, and then take the middle value. In this case, the data is arranged in numerical order as 0, 5, 10, 10, 12, 15, 15, 20, 25, 30, 30, 35, 35, 45, 60. The middle value is 20, which is the median.
Answer:
17.5
Step-by-step explanation:
To find the median of a set of numbers, we need to arrange the numbers in order from smallest to largest and then find the middle value.
In this case, the numbers in the set arranged in ascending order are:
0, 5, 10, 10, 12, 15, 15, 20, 25, 30, 30, 35, 35, 45, 60
There are 15 numbers in the set, which means that the middle value is the eighth number. Since there are two numbers in the middle (15 and 20), we take the average of these two numbers to find the median:
median = (15 + 20) / 2 = 17.5
Therefore, the median of the set of numbers is 17.5.
A real estate agent has 19 properties that she shows. She feels that there is a 30 % chance of selling any one property during a
week. The chance of selling any one property is independent of selling another property. Compute the probability of selling at
least 5 properties in one week. Round your answer to four decimal places.
Answer: This is a binomial probability problem. Let X be the number of properties sold during a week, then X has a binomial distribution with parameters n=19 and p=0.3.
The probability of selling at least 5 properties is:
P(X ≥ 5) = 1 - P(X < 5)
To calculate P(X < 5), we can use the binomial cumulative distribution function or the normal approximation to the binomial distribution.
Using the binomial cumulative distribution function, we have:
P(X < 5) = Σ P(X = k) for k = 0 to 4
Using the formula for the binomial probability mass function, we get:
P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
= (0.7)^19 + 19(0.3)(0.7)^18 + 171(0.3)^2(0.7)^17 + 969(0.3)^3(0.7)^16 + 3876(0.3)^4(0.7)^15
Using a calculator or statistical software, we get:
P(X < 5) = 0.95044
Therefore, the probability of selling at least 5 properties in one week is:
P(X ≥ 5) = 1 - P(X < 5) = 1 - 0.95044 = 0.0496 (rounded to four decimal places).
So the probability of selling at least 5 properties in one week is approximately 0.0496 or 4.96%.

Fοr instance, in equatiοn 3x + 5 = 14, the equal sign separates the numbers by a space. Mathematical expressiοns can be used tο describe the relatiοnship between the twο sentences οn either side οf a letter. The lοgο and the particular piece οf sοftware frequently cοrrespοnd. like, fοr instance, 2x - 4 = 2.
[tex]P = \frac{rP}{(1 - (1 + r)^{-n}}[/tex]
where P is the regular mοnthly payment, r is the interest rate each mοnth, n is the number οf payments, and P is the amοunt οf interest that has already been paid in dοllars.
r = 0.027 / 12 = 0.00225
The number οf payments must then be determined. There are 120 mοnthly payments fοr a 10-year mοrtgage.
n = 120
P = 1% * $100,000 = $1,000
Nοw that the data have been entered, we can cοmpute the monthly payment:
[tex]P = (0.00225 \times $99,000 / (1 - (1 + 0.00225)^{(-120)})) + $8.33[/tex]
where $8.33 represents the mοnthly charge fοr the prepaid interest and $99,000 represents the tοtal amοunt bοrrοwed after subtracting the prepaid interest.
If we cοndense this phrase, we get:
P = $959.49

determine whether the pair of functions and inverse functions f(x)=6x-15 and g(x)=1/6x+5/2
The pair of functions are inverses, as their compositions result in x.
What is the composite function of f(x) and g(x)?The composite function of f(x) and g(x) is given by the following rule:
(f ∘ g)(x) = f(g(x)).
It means that the output of the inside function serves as the input for the outside function.
If two functions are inverse, the composites f(g(x)) and g(f(x)) both result in x.
The composite functions for this problem are given as follows:
f(g(x)) = f(x/6 + 5/2) = 6(x/6 + 2.5) - 15 = x + 15 - 15 = x.g(f(x)) = g(6x - 15) = 1/6(6x - 15) + 2.5 = x - 2.5 + 2.5 = x.Hence they are inverses.

Q.15. Bloom Pet Supplies makes a profit of $5.50 per bag on its line of dog food. Total expenses
associated with the sale of dog food stand at $2,500 per day. If the store wants to make a profit of
at least $5,225 per day, which inequality represents how many bags of dog food d the store must
sell to meet their goal?
A. 5.50d 2,500 ≥ 5,225
B. 5.50 2,500d ≥ 5,225
C. 5.50d +2,500 ≥ 5,225
D. 5.50 +2,500d ≥ 5,225
Answer:
Let's use option C to represent the relationship between the number of bags of dog food sold and the profit made:
Profit per bag of dog food = $5.50
Total expenses per day = $2,500
The store wants to make a profit of at least $5,225 per day.
If d represents the number of bags of dog food sold, then the profit made can be represented as:
Profit = Revenue - Expenses
Revenue = Profit + Expenses
Revenue = $5.50d + $2,500
To make a profit of at least $5,225 per day, we can set up the following inequality:
$5.50d + $2,500 ≥ $5,225
Simplifying:
$5.50d ≥ $2,725
Dividing both sides by $5.50:
d ≥ 500
Therefore, the store must sell at least 500 bags of dog food per day to make a profit of at least $5,225 per day.
The correct inequality that represents this relationship is option C: 5.50d +2,500 ≥ 5,225.
find the perimeter of P and area of A of triangle JKL J(-5,-7),K(2,3),L(-1,-7)
Answer: To find the perimeter of triangle JKL, we need to find the length of each side and add them up. We can use the distance formula to find the length of each side:
Side JK = sqrt[(2 - (-5))^2 + (3 - (-7))^2] = sqrt[7^2 + 10^2] = sqrt[149]
Side KL = sqrt[(-1 - 2)^2 + (-7 - 3)^2] = sqrt[(-3)^2 + (-10)^2] = sqrt[109]
Side LJ = sqrt[(-1 - (-5))^2 + (-7 - (-7))^2] = sqrt[4^2] = 4
Therefore, the perimeter of triangle JKL is:
P = JK + KL + LJ = sqrt[149] + sqrt[109] + 4
To find the area of triangle JKL, we can use the formula:
A = 1/2 * base * height
We can choose any side as the base, and the corresponding height will be the perpendicular distance from the opposite vertex to the base. Let's choose side KL as the base. The height from vertex J to side KL is the perpendicular distance between J and the line containing KL. We can find this distance using the formula for the distance between a point and a line:
Area = 1/2 * KL * h
where h = |(2 - (-1))( -7 - 3) - (-5 - 2)(-1 - 3)| / sqrt[(-1 - 2)^2 + (-7 - 3)^2]
Simplifying the above expression, we get:
h = 24 / sqrt[109]
Therefore, the area of triangle JKL is:
A = 1/2 * KL * h = 1/2 * sqrt[109] * 24 / sqrt[109] = 12
So, the perimeter of triangle JKL is sqrt[149] + sqrt[109] + 4, and the area of triangle JKL is 12.

Answer: The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours
Step-by-step explanation:
Unit rate is the ratio of the distance travelled o the time taken.
For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;
If distance = 9/8 miles and time = 5/6 hours
Hence the ratio that has a unit rate is 9/8 miles:5/6hours

02/00
HELPPPP MEEEW
Answer:
a) opens down
c) directrix at y = 1/8
d) vertex at (-1/2,0)
Step-by-step explanation:
Starting from the given equation:
4x^2 + 4x + 2y + 1 = 0
We can rearrange to obtain the standard form of the equation of a parabola:
2(y + 1/2) = -4(x + 1/2)^2 + 1
(y + 1/2) = -2(x + 1/2)^2 + 1/2
Comparing to the standard form:
(y - k) = a(x - h)^2
We can see that the vertex of this parabola is at the point (-1/2, -1/2).
Next, we can find the axis of symmetry by noting that the parabola is symmetric about a vertical line passing through the vertex. This line is given by:
x = -1/2
We can also determine whether the parabola opens upward or downward by looking at the sign of the coefficient a. In this case, a = -2, so the parabola opens downward.
The distance between the vertex and the directrix is given by |1/(4a)|. Therefore, the distance between the vertex (-1/2, -1/2) and the directrix is:
|1/(4(-2))| = 1/8
So the directrix of the parabola is the horizontal line y = 1/8.
Therefore, the correct options are:
a) opens down
c) directrix at y = 1/8
d) vertex at (-1/2,0)
The other options are incorrect:
b) The parabola does not open to the left.
e) The directrix is not a vertical line at x = -3/8.

The ribbon costs $3 for each yard. Write an expression for the total cost (in dollars) of the ribbon.
As a result, the price of the ribbons is proportional to the number of party favours, with each Favour costing (3/4) dollars.
What are quantity and example?A measurable quality such as weight, length, time, volume, or pressure is referred to as quantity. A unit is a unit of measurement that is used to measure other quantities (for example, a gramme, a second, a liter, or a pascal are unit of the above quantities). Chemists employ a wide range of measurements.
The amount of ribbon required for n party favours is calculated as follows:
19n inches (since each party Favour requires 9 inches of ribbon)
As the price is stated in dollars per yard, we must first convert the amount of inches to yards before we can determine the ribbon's total cost. Since there are 36 inches in every yard, we can calculate the number of yards by dividing the total amount of inches by 36:
Total yards of ribbon = (9n) / 36 = (n) / 4
