Tiffany sees this given dilation and claims that the scale factor is 2
because 4 is twice as big as 2. Is this a scale factor of 2? Explain.
Answers
Answer:
The scale factor is not 2
Step-by-step explanation:
Given
See attachment for the dilated triangles
Triangle ABC is dilated through center point O to form triangle A'B'C'.
From the attachment, we have:
[tex]OC = 2[/tex] i.e. the distance from the center point to C
and
[tex]OC' = 6[/tex] i.e. the distance from the center point to C'
The length of OC' is calculated using:
[tex]OC' = OC + CC'[/tex]
[tex]OC' = 2 + 4[/tex]
[tex]OC' = 6[/tex]
The scale factor (k) is then calculated by dividing OC' by OC
[tex]k = \frac{OC'}{OC}[/tex]
[tex]k = \frac{6}{2}[/tex]
[tex]k = 3[/tex]
Hence, Tiffany's claim is incorrect.

hello, can i please have help on this question thank you
Answers
Answer:
Step-by-step explanation:
a) One can get maximum score when all the 20 questions answered are correct.
Maximum score = 20*3 = 60 points
b) Minimum score = 20 * (-2) = -40 points
c) Points for correctly answered questions = 10*3 = 30
Incorrectly answered questions = 14 - 10 = 4
Points for incorrectly answered questions = 4 * (-2) = -8
Total score = 30 + (-8) = 22
d) Points for correctly answered questions =5*3 = 15
Points for incorrectly answered questions = 13 * (-2) = -26
Total score = 15 + (-26) = -11

Natural numbers refer to numbers that are used for counting.
Whole numbers include 0 and natural numbers.
An integer is a collection of whole numbers and their negatives.

1. Taylor needs to purchase a car. The car Taylor plans to purchase costs $10,000. Taylor has saved $2,000 to use as a down payment for the car. Taylor is offered credit terms of 5% APR for 5 years. Please calculate the following:
a. To purchase the car, what is the amount Taylor will need to finance? (1 point)
b. In one year, how much interest will Taylor pay on this loan?
(Interest = Principal x Rate x Time) (1 point)
c. After 5 years, in order for Taylor to own the car, what will the actual, total cost of the car be in dollars? (2 points) (down payment + amount financed + interest = total cost of the car)
Answers
Answer:
a. The amount Taylor will need to finance is $8,000
b. The amount Taylor pays as interest in one year is $400
Step-by-step explanation:
The given parameters of the financing for the car are;
The cost of the car Taylor plans to purchase, C = $10,000
The amount Taylor has saved to be used as down payment, S = $2,000
The interest rate of the credit Taylor is offered = 5%
The duration given for repayment of the loan = 5 years
a. To purchase the car, the amount Taylor will need to finance, 'P', is given as follows;
P = C - S
∴ P = $10,000 - $2,000 = $8,000
b. The amount of interest on the loan in one year, 'I', is given by the following formula;
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Where;
I = The interest payed
P = The principal amount taken as loan = $8,000
R = The interest rate = 5% APR
T = The time period the interest is applied = 1 year
Plugging in the values, we get;
[tex]I = \dfrac{\$ \, 8,000 \times 5 \times 1}{100} = \$ \, 400[/tex]
The interest Taylor will pay on the loan in one year, I = $4,00

Answers
Answer: 999 sq ft
Step-by-step explanation:
Becuase i said so cusseiniji
Answer:
The answer is 44 ft^2
Step-by-step explanation:
You would first make the shape into two rectangles and solve for two different areas.
I started with the one on the bottom. That would be Length= 12 feet * Width= 2 feet= 24 feet
Then, solve for the second rectangle. You know that the far left side is 12 feet because the bottom base is 12 feet and this was once a square, meaning all sides were equal. Knowing this and that you already solved for the bottom rectangle you'd subtract 2 from 12 to give you a new side total of 10 feet. Then you'd solve for the area of the top rectangle.
That would be Length= 2 feet * Width= 10 feet= 20 feet
Finally, you'd add both totals together. 20+24= 44 ft^2

This is what I remember, but you need to check this order of arithmetic operations.
Parentheses first then exponents ( you don't have any) multiplication and division left to right and then addition and subtraction again left to right
2 + (3 – 2 x 2) x 1 so 3 – 2 x 2 equals 3 - 4 which equaltes to
2 + (-1) x 1 -1 x 1 = -1
2 + (-1) x 1 is to clearer to me than 2 + -1 x 1 maybe not

Ind the volume of a pyramid with a square base, where the side length of the base is 15.3\text{ m}15.3 m and the height of the pyramid is 19.6\text{ m}19.6 m. Round your answer to the nearest tenth of a cubic meter.
Answers
Answer:
1,487.3m³
Step-by-step explanation:
Volume of a square based pyramid is expressed as;
V = BH/3
B is the base area
H is the height of the pyramid
Since the side length of the base is 15.3m;
Base area = L²
Base area = 15.3²
Base area = 234.09m²
Height of pyramid = 19.6m²
Get the volume
Volume of the square based pyramid = (234.09*19.6)/3
Volume of the square based pyramid =1,487.3m³ (to the nearest tenth)

A sprinkler is set to water the section of lawn represented by the shaded region in the circle below. which measurement is closest to the area of the lawn watered by this sprinkler
Answers
Answer:
A = 64.141
Step-by-step explanation:
150/360 = 0.41667
41.667% of the circle is shaded so when we find the area we will multiply ir by 0.41667 to find only the shaded area
A=πr^2 x 0.41667
A = π(7)^2 x 0.41667
A = 64.142
The area of the lawn watered by this sprinkler is 64 square feet.
What is area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula to find the area of a sector = θ/360° ×πr².
From the given circle, central angle is 150° and the radius of a circle is 7 feet.
Here, the area of a sector = θ/360° ×πr²
= 150°/360° ×3.14×7²
= 0.417×3.14×49
= 64.15962
≈ 64 square feet
Therefore, the area of the lawn watered by this sprinkler is 64 square feet.
