Every coordinate point of the original triangle is multiplied by the scale factor 1/2 if the scale factor is 1/2. multiplying by half after a scale factor of two.
What is Scale Factor?The scale factor of a shape refers to the amount by which it is increased or shrunk. It is applied when a 2D shape, such as a circle, triangle, square, or rectangle, needs to be made larger.
K is the scaling factor for x in the equation y = Kx. This expression can also be visualised in terms of proportionality:
y ∝ x
K can therefore be regarded as a proportionality constant in this context.
Basic Proportionality Theorem also aids in a better understanding of the scale factor.
Shapes in various dimensions can be scaled using the Scale Factor. In geometry, we study many geometrical forms that exist in both two- and three-dimensions. The scale factor is a way to compare figures with similar appearances but differing scales or measurements. Consider two circles that resemble one another but may have different radii.
The scaling factor indicates how much a figure has increased or decreased from its initial value. With the use of the scale factor, any original shape can be drawn in an enlarged or shrunk form.

An office building has two elevators. One elevator starts out on the 4th floor, 35 feet above the ground, and is descending at a rate of 2.2 feet per second. The other elevator starts out at ground level and rising at a rate of 1.7 feet per second
The system of equations is y = 35 - 2.2x and y = 1.7x.
The solution of the system of equations is (8.97,15.25).
At about 8.97 seconds, both elevators will be about 15.25 feet above the ground.
What is an elevator?
An elevator, often known as a lift, is a car that moves vertically in a shaft to transport passengers or freight between the levels of a multistory building. Most modern elevators are propelled by electric motors via a system of wires and sheave with the assistance of a counterweight (pulleys).
Given that there are two elevators in an office. The 4th floor of the office at 35 feet above the ground and is descending at a rate of 2.2 feet per second.
The equation represents the height of the elevator above the ground after x seconds is y = 35 + (-2.2)x. Since the elevator is descending at a rate of 2.2 feet per second.
The other elevator starts out at ground level and rises at a rate of 1.7 feet per second.
The equation represents the height of the elevator above the ground after x seconds is y = 1.7x. Since the elevator is rising at a rate of 1.7 feet per second.
The system of equations is
y = 35 + (-2.2)x .....(i)
y = 1.7x ........(ii)
Solve the equations substitution method.
Putting y = 1.7x in equation (i)
1.7x = 35 + (-2.2)x
1.7x = 35 - 2.2x
Add 2.2x on both sides:
1.7x + 2.2x = 35
3.9x = 35
Divide both sides by 3.9:
x = 35/3.9
x = 8.97
Putting x = 8.97 in equation (ii)
y = 1.7 × 8.97
y = 15.25
After 8.97 seconds, the elevators will be 15.25 feet above the ground.

Periodical Express is a newspaper printing company. They printed 450 copies of The Informer in just 15 seconds! They next need to print 300 copies of the Sport Report.
If they print at the same rate, how many seconds will it take to print the Sport Report?
Answer: To find out how many seconds it will take to print 300 copies of the Sport Report, we can use the formula:
time = (number of copies) / (rate of printing)
We know that the rate of printing for The Informer is 450 copies in 15 seconds. To find the rate of printing per second, we can divide the number of copies by the time in seconds:
rate of printing = 450 / 15 = 30 copies per second
So to find out how long it will take to print 300 copies of the Sport Report, we can use this rate of printing and plug it into the time formula:
time = (number of copies) / (rate of printing)
time = 300 / 30
time = 10 seconds
Therefore, it will take 10 seconds to print 300 copies of the Sport Report at the same rate as The Informer.

How to find a interior and exterior angle of triangle? Interior angles of a triangle are the angles inside the triangle that are formed by the intersection of two sides. To calculate the measure of an interior angle, you can use the formula: interior angle = 180-(angle 1 + angle 2). This formula works for all triangles, regardless of the size or shape. Exterior angles of a triangle are the angles outside the triangle that are formed by extending one of the sides. To calculate the measure of an exterior angle, you can use the formula: exterior angle = angle 1 + angle 2. This formula works for all triangles as well. To find the interior and exterior angles of a triangle, you need to know the measures of the angles of the triangle. If you don’t know the measures of the angles, you can use the following steps:
1. Measure the length of each side of the triangle.
2. Using the triangle inequality theorem, determine the angles of the triangle.
3. Use the formula to calculate the measure of each interior and exterior angle.
By following these steps, you can easily calculate the interior and exterior angles of a triangle.Solution:
To measure a missing angle of triangle,
∠ABC + ∠ACB + ∠CAB = 180°
x + 132° + 27° = 180°

Amir operates a large lobster boat. The operating cost for the boat is $2.250 each day. At the end of each day, he sells all his freshly caught lobster to either the local restaurant or the local grocery store with the following conditions:
• The price per pound that the restaurant is willing to pay follows a triangular distribution with minimum value $1.50, maximum value $5.50, and likeliest value $3.50.
• The price per pound that the grocery store is willing to pay is decreasing with more lobsters: $3.85 - 50.0005 * y, where y is the total lobster amount sold in pounds.
• The amount of lobster that Amir catches in a single day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.
Amir decides to sell a fixed percentage of lobster to the local restaurant and the rest to local grocery stores. Using either math or simulation, can you help Amir determine what percentage he should choose in order to maximize his expected profit in the long run?
Previous question
The expected profit in the long run can be determined by calculating the expected value of the total revenue from selling the lobsters. The expected total revenue is the sum of the expected revenue from selling the lobsters to the restaurant and the from selling the lobsters to the grocery store.
The expected value of the revenue from selling the lobsters to the restaurant can be calculated by multiplying the expected price per pound from the restaurant by the expected amount of lobsters caught in a day. The expected price per pound from the restaurant follows a triangular distribution with minimum value $1.50, maximum value $5.50, and likeliest value $3.50. The expected amount of lobsters caught in a day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.
The expected value of the revenue from selling the lobsters to the grocery store can be calculated by multiplying the expected price per pound from the grocery store by the expected amount of lobsters caught in a day. The expected price per pound from the grocery store is decreasing with more lobsters: $3.85 - 50.0005 * y, where y is the total lobster amount sold in pounds. The expected amount of lobsters caught in a day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.
Given the expected values of the total revenue from selling the lobsters to the restaurant and the grocery store, Amir can use simulation to determine the optimal percentage of lobsters to sell to the restaurant in order to maximize his expected profit in the long run. He can run several simulations with different percentages of lobsters to be sold to the restaurant and compare the expected profits for each simulation. The percentage that produces the highest expected profit is the optimal percentage for Amir to maximize his expected profit in the long run.

Chad bought a box of donut hole that contain 60% glazed and the ret powdered ugar. The box ha 12 powdered ugar donut hole. How many glazed donut hole are in the box Chad bought?
The box has 18 glazed donut hole that Chad bought.
The percentage of glazed donut holes = 60%
The percentage of powdered sugar donut hole = (100 - 60) % = 40%
Let us consider the total number of donut hole in the box bought by Chad to be 'x'
Number of powdered sugar donut hole = 12
Hence, we can say that the number of powdered sugar donut hole in the box Chad bought is:
(40% of x) = 12
Therefore, x = (12 x 100) / 40 = 30
Since the total number of donut hole in the box = 30
The number of glazed donut hole = 30 - 12 = 18

This is an observational study. The researchers are observing and measuring the relationship between media usage and tiredness, but they are not manipulating or controlling any variables. They are collecting data by randomly selecting homes to visit and interviewing the adult member of the household whose birthday was nearest.
An observational study draws conclusions from a sample of a population in disciplines like epidemiology, social sciences, psychology, and statistics when the independent variable is not under the researcher's control due to ethical considerations or practical limitations. One typical observational study examines how a therapy may affect its participants, but the researcher has no control over which group the subjects are assigned to—the treated group or the control group. Unlike experiments like randomized controlled trials, when each subject is arbitrarily assigned to either a treated group or a control group, this does not happen.

What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
The equation to find final amount in compound interest is,
A = P (1 + r/n)^(n t)
Here A is the final amount, P is the initial amount, r is the rate of interest, n is the number of times compounding is done in a year, t is the time in years.
Given, A = $93,000
t = 19 years
r = 2.2% = 0.022
n = 4 (since compounding is quarterly)
93,000 = P [1 + (0.022/4)]^(4×19)
93,000 = P [1.0055]^(76)
93,000 = P (1.517)
