which of the following algebraic represents shows a dilation that is an enlargement ?
Answers
Answer:
D: (5/2x, 5/2y)
Step-by-step explanation:
A dilation is an enlargement only when the dilation factor > 1
Only 5/2 is greater than 1
Others are less than 1
Dilation is a transformation that changes the size of a figure without changing its shape. It is represented algebraically as 'y=a*x' or 'y=a*x+b', where 'a' is the scale factor. If 'a' is greater than 1, it represents an enlargement.
Explanation:In algebra, a dilation is a transformation that changes the size of a figure without altering its shape. It can either enlarge (expansion) or reduce (contraction) a figure depending on the scale factor. If the scale factor is more than 1, the dilation is an enlargement. Any algebraic representation, such as 'y=a*x' or 'y=a*x+b' where 'a' is greater than 1, represents a dilation that is an enlargement. For instance, if we have y=2x, the '2' is the scale factor that determines the enlargement. The greater the number, the larger the image after dilation.

Quadrilateral DUCKDUCKD, U, C, K is inscribed in circle OOO. What is the measure of \angle K∠Kangle, K?
Answers
Answer:
Measure of ∠K=180-∠U
Or
Measure of ∠K=1/2m(arc DUC)
Step-by-step explanation:
Given:
DUCK quadrilateral inscribed in circle with center O
To Find:
Measure angle K
Solution:
Here the Quadrilateral in inscribed in a circle with center O named as DUCK
So angle K and U are opposite to each other
We know that the angle of Quadrilateral inscribed in a circle are supplemenatry angles
Hence
∠U+∠K=180
Or The ∠K=1/2*m∠arc(DUC).
Hence depending on the given value for arc measure or angle of quadrilateral we calculate the angle K
Answer:
angle K = 95 degrees
Step-by-step explanation:
180 - U = K
180 - 85 = K

The required value of a number of people is 20 who don't do either.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
here, we have,
Column 1 has the entries run, do not run, and total. Column 2 is called lift weights, and it has the values 40, blank, and 65. Column 3 is captioned "do not lift weights" and has entries blank, x, and blank. Column 4 is called total and has the entries 75, blank, and 120.
As per the given information, the required solution would be as:
The number of people who do not run or lift weights by first determining that 55 individuals do not lift weights and 35 people run but do not lift weights. When you subtract 35 from 55, you get 20 people who don't do either.
Thus, the required value of a number of people is 20 who don't do either.

The number x represents the number of people who do not run and do not lift weights. To calculate x, subtract the number of people who lift weights from the total number, then subtract the number of people who run and lift weights.
Explanation:To find the number that x represents, we can use the information given in a table with a row and column structure. From the total number of people (120) and the number of people that lift weights (65), we deduct the number that run and lift weights (40), leaving us with the number of people who either do not run or do not lift weights.
The total number of people that run is given as 75. Therefore, the number who do not run is 120 - 75 = 45. We know that 65 people lift weights, so by subtraction, 120 - 65 gives us the total number of people who do not lift weights.
Now, using the total number of people who do not lift weights, we can calculate the value of x, which represents the number of people who do not run and also do not lift weights. Subtracting the number of people who run but do not lift weights from the total number who do not lift weights gives us:
Number of people who do not lift weights = Total number of people - Number of people who lift weights
Number of people who do not lift weights = 120 - 65 = 55
Therefore, x equals 55 - 40, since 40 is the number of people who run and lift weights.
x = 55 - 40 = 15

Which is the better buy, 12 ounces for $7.50 or 1 pound for $9.00? Explain your reasoning.
Answers
and 9/16 = to .56
To determine the better buy, compare the cost per ounce for each option. The second option of 1 pound for $9.00 is the better buy with a lower cost per ounce.
Explanation:To determine which option is the better buy, we need to compare the cost per ounce for each option.
The first option is 12 ounces for $7.50. To find the cost per ounce, we divide the total cost ($7.50) by the number of ounces (12), giving us a cost of $0.625 per ounce.The second option is 1 pound for $9.00, which is equivalent to 16 ounces. To find the cost per ounce, we divide the total cost ($9.00) by the number of ounces (16), giving us a cost of $0.5625 per ounce.Therefore, the second option of 1 pound for $9.00 is the better buy as it has a lower cost per ounce.

Josie found a small bird bath at a garage sale. The bird bath has a circular opening with a radius of 10 cm, as shown in the diagram below. Using 3.14 for pi, Josie calculates that the water in the small bird bath has 314 cm2 of surface area. Josie lives in a wooded area with lots of birds, so she plans to use the bird bath she found as a scale model to build a much larger bird bath. If she doubles the dimensions of the scale model, how many square centimeters of surface area will the larger bird bath have for bathing?
Answers
Answer: 1256cm
Step-by-step explanation:
Final answer:
When Josie doubles the radius of the bird bath to build a larger one, the new surface area will be 1256 cm², as surface area quadruples when doubling the radius of a circle.
Explanation:
Josie calculated that the surface area of her small bird bath with a radius of 10 cm is 314 cm^2. If she doubles the dimensions for a larger bird bath, the new radius will be 20 cm. To find the surface area of the larger bird bath, we use the formula for the area of a circle, A = πr².
Plugging in the new radius:
A = 3.14 × (20 cm)^2
A = 3.14 × 400 cm^2
A = 1256 cm2
This means the surface area for the larger bird bath Josie plans to build will have 1256 cm^2 for bird bathing. This calculation demonstrates how the surface area of a circle quadruples when the radius is doubled, which is consistent with the principle that surface area scales with the square of the dimension changes.

m∠BOC = 6x - 6
m∠AOB = 5x + 8

We know that the segments OA ⊥ OC so they are complementary angles.
1.- The sum of complementary angles equals 90°
m∠BOC + m∠AOB = 90°
2.- Substitution
6x - 6 + 5x + 8 = 90°
3.- Solve for x
6x + 5x = 90 + 6 - 8

11x = 88

x = 88/11
x = 8

Final answer:
To find the actual length of each leg of the Apollo Lunar Module, use the given scale of 1 to 50. Measure the length of the leg on the drawing and multiply it by the scale factor.
Explanation:
To find the actual length of each leg of the Apollo Lunar Module, we need to use the given scale of 1 to 50. This means that 1 unit on the drawing represents 50 units in real life. First, measure the length of the leg on the drawing. Let's say it measures 3 centimeters. To find the actual length, multiply the measured length by the scale factor: 3 cm x 50 = 150 centimeters. Therefore, each leg of the Apollo Lunar Module is 150 centimeters long.
