How do you dilate a triangle with a scale factor of 2 3?
The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.The dilation o a triangle with a scale factor of 2 3 represents a contraction.
How to Dilate a triangle with a scale factor ?
The scale factor is defined as the proportion of the new image's size to that of the previous image. A fixed location in the plane serves as the centre of dilatation. The scale factor and the centre of dilation are used to determine the dilation transformation.
The image stretches if the scaling factor is greater than 1.The image contracts if the scale factor is between 0 and 1.The original image and the resulting image are consistent if the scale factor is 1.Finding the dilation's centre point is the first step in determining the scale factor. Next, we measure the distances between the centre point and various points on the preimage and the image. According to Math Bits Notebook, the scale factor is equal to the ratio of these distances.
Since each angle is congruent, every segment is proportional, the slope of every segment is preserved, and the perimeter of the preimage and image have the same scale factor, we may use dilation scale factors to compress or enlarge a figure to the size we desire.
Dilate a triangle with a scale factor
Assume that the coordinate plane's centre of dilation is at (0, 0) at the origin. Every coordinate point of the original triangle is multiplied by the scale factor 2/3 if the scale factor is 2/3. multiplying by half after a scale factor of two.

Answer:
So in total, 1681 pennies were collected.
Step-by-step explanation:
divide the total amount collected, $16.81, by the value of a penny, which is $0.01.
16.81 / 0.01 = 1681 pennies.
So in total, 1681 pennies were collected.

Trisha and Byron are washing and vacuuming cars to raise money for a class trip. Trisha raised $38 by washing
5 cars and vacuuming 4 cars. Byron raised $28 by washing 4 cars and vacuuming 2 cars. Find the amount they
charged to wash a car and vacuum a car.
Answer:
Step-by-step explanation:
Let x = amount charged for washing a car
y = amount charged for vacuuming a car
Solution :38 = 5x + 4y (1)
28 = 4x + 2y (2)
Can be solved by substitution or simply subtracting the (1) and (2) equation.
By Substitution:
38 = 5x + 4y ---> solve for x
38 - 4y = 5x (transposed 4y to the other side of the equation and it's sign changes from (+) to (-).
[tex]\frac{38-4y}{5} =x[/tex]
substitute the value of x to the (2) equation.
28 = 4x + 2 y
[tex]28=4(\frac{38-4y}{5})+2y[/tex]
[tex]28=\frac{152-16y}{5} +2y[/tex] , then multiply both side by 5 to eliminate the denominator 5.
140 = 152 - 16y + 10y (transposed 152 to the other side, change sign from (+) to (-)).
140 - 152 = -16y + 10 y
-12 = -6y (divide both side by (-6)
y = 2 or $2 (amount charged for vacuuming)
Using any of the 2 equation, we can solve for the value of x.
38 = 5x + 4 (2) (we substitute, the value of y)
38 - 8 = 5x
30/5 = x
x= 6 or $6 (amount charged for washing)

Josephine wrote the numbers one to one hundred and placed them in a bag. If he randomly selects a number without looking, what is the probability that the number is greater than seventy-eight? The probability that the number is greater than seventy-eight is twenty-two out of one hundred, or twenty-two percent. This is because there are a total of one hundred numbers in the bag, and out of those one hundred numbers, seventy-eight are less than seventy-eight. Therefore, there are twenty-two numbers that are greater than seventy-eight. The probability of selecting a number greater than seventy-eight is twenty-two out of one hundred, or twenty-two percent.

(a) calculate the number of tins in one bag. (b) if the business man made total of sha 29,640. how many bags had he sol? (c) the businessman later used the total sales to buy more maize at shs.926.25 per bag he sold half of the bags to the maize millers the rate of shs.1,390 per bag and retailed the remaining at his stall to consumers at shs.39 per tin. which option would earn more profit and by how much? (2mk) (d) express the difference as a percentage of the sales to the consumers.
a) To calculate the number of tins in one bag, we can use the information given in the problem: "he later sold the maize39 per tine"
So we can assume that one bag of maize is divided into tins and the price per tin is 39 shs.
b) To find out how many bags the businessman sold, we can use the information that he made a total of 29,640 shs in profit.
We know from the problem that the profit per bag is 515 shs, so to find out how many bags he sold we can divide the total profit by the profit per bag: 29,640 shs / 515 shs/bag = 57.5 bags
c) To find out how much profit the businessman made by selling half of the bags to the maize millers, we can use the information that he bought the bags at 926.25 shs and sold them at 1,390 shs.
We know that he sold half of the total number of bags, so we can divide the total number of bags by 2: 57.5 bags / 2 = 28.75 bags
To find out the total profit he made, we can multiply the number of bags sold by the profit per bag: 28.75 bags * (1,390 shs - 926.25 shs) = 22,447.5 shs
d) To express the difference as a percentage of the sales to the consumers, we can use the information that the businessman sold the bags to the maize millers at 1,390 shs and to the consumers at 39 shs.
To find the difference, we can subtract the price he sold the bags to the consumers from the price he sold the bags to the maize millers: 1,390 shs - 39 shs = 1351 shs
To find the percentage of the difference, we can divide the difference by the price he sold the bags to the consumers and multiply by 100: (1351 shs / 39 shs) * 100 = 34,641.03%

Step-by-step explanation:
All of the interior angles of a triangle sum to 180 °
Smallest is 5 out of (14 + 5 + 11) = 5/30 ths of 180° = 30°
Middle is 11/30 ths = 66°
Largest is 14/30 ths = 84°
Answer:
30° , 66° , 84°
Step-by-step explanation:
sum the parts of the ratio, 14 + 5 + 11 = 30 parts
divide the sum of the angles in a triangle 180° by 30 to find the value of one part of the ratio.
180° ÷ 30 = 6° ← value of 1 part of the ratio , then
