Answer:
C. not similar, dilations are involved
Step-by-step explanation:
For geometric figures, such as triangles, we generally study a couple of kinds of transformations.
One is the "rigid transformation" which lets us move, rotate, or reflect the figure any way we like, but we keep it the same size—as though it were cut from cardboard or anything else that holds its shape and size. Any figures transformed by a rigid transformation are congruent.
Another is very much like the "rigid transformation", but dilation is involved. That is, the figure is allowed to be stretched or shrunk uniformly (by the same factor in every direction). Figures transformed in this way are similar, but are not congruent.
In this diagram, your triangle has been reflected and changed in size by a different factor horizontally than vertically. Hence dilation is involved (answer choices A or C), but because the factors are different, the figures are not similar (answer choice C).

Rotations may be involved in similarity transformations, too. For some reason, that possibility was left off of choices A and C. (On the other hand, rotation is equivalent to a suitable set of reflections.)

Using Cramer's Rule, the value of x in the given system of linear equations is approximately -5.09.
Explanation:To solve the system of linear equations using Cramer's Rule, we need to find the determinants of the coefficient matrix and the matrices obtained by replacing the corresponding column of the coefficient matrix with the constant matrix. Let's find the determinants:
Determinant of the coefficient matrix = |3 -4| = (3)(-6) - (4)(1) = -18 - 4 = -22
Determinant of the matrix obtained by replacing the x column = |-18 -4| = (-18)(-6) - (-4)(1) = 108 - (-4) = 112
Now, using Cramer's Rule:
x = Determinant of the matrix obtained by replacing the x column / Determinant of the coefficient matrix
x = 112 / -22 = -5.09
Therefore, the value of x in the given system of linear equations is approximately -5.09.

Antuan deposited $2590 into a 3 year CD at an interest rate of 2.3% compounded quarterly.
How much interest did the account earn after the three years? Show your work.
Answers
Answer:
the interest rate is $183.89 =~ $ 184
Step-by-step explanation:
In this question, Antuan deposited $2590 into a 3 year CD (Certificate of Deposit) at an interest rate of 2.3% compounded quarterly. We need to find the interest account earned after 3 years.
Formula used will be :
[tex] Interest = P ( 1 + r/n) ^ n ^ t - P[/tex]
Where
P= Principal amount
r= interest rate (in decimals)
n= no of times the interest is compounded
t = no of years
Here we are subtracting P because we only need interest amount and not the future value.
Using this formula and finding the value will be:
P= $2590
r = 2.3 % or 0.023
n = 4
t = 3
[tex]Interest = 2590 * ( 1 - 0.023 / 4) ^ 4^ * ^ 3 - 2590[/tex]
[tex]Interest= 2590 (1.071) -2590\\Interest= 2773.89 - 2590\\Interest= 183.89[/tex]
So the interest rate is $183.89 =~ $ 184

Solve the triangle given two angles and one side.
Answers
Answer:
a = 102.05
b = 393.76
B = 93°
Step-by-step explanation:
The law of sines tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
Since the sum of angles in a triangle is 180°, angle B must be ...
B = 180° -72° -15° = 93°
and the unknown sides must be ...
a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192
B = 93°
b = 375·sin(93°)/sin(72°) ≈ 393.75796

The floor of a shed has an area of 70 square feet. The floor is in the shape of a rectangle whose length is 4 feet less than twice the width. Find the length and the width of the floor of the shed.
Answers
Answer:
length: 10 ft; width: 7 ft.
Step-by-step explanation:
Factorizations of 70 are ...
70 = 1·70 = 2·35 = 5·14 = 7·10
The last pair of numbers has the relation that 2·7 -10 = 4, so the numbers 7 and 10 can be used for width and length.
The length is 10 ft; the width is 7 ft.
Each exterior angle of a regular n-gon shaped gazebo at Logan Park measures 22 1/2. Each exterior angle of a regular n-gon shaped gazebo at Cerro Park measures 15 15/23. By how many sides the gazebo at Logan Park is different from the gazebo at Cerro Park?
Answers
Answer:
the exterior angles of a polygon sum to 360
so the number of sides is 360/45
-PlushDna
Answer:
The difference in number of sides from one park to the next is 7
Step-by-step explanation:
For all polygon's the exterior angles combine to measure to 360 degrees. So to find the number of sides of each gazebo, we simply divide 360 by the measure of each individual exterior angle. We'll start with Logan Park.
360/22.5 = 16 sides
Now we can do the same with Cerro Park.
360/15.65 = 23 sides
Therefore, the difference in sides would be 7
23 - 16 = 7
Eva buys online tickets to a play for her family. Each ticket costs $45.00 and there is a fee of $17.99. The total cost for tickets including the fee is $422.99. How many tickets does Eva buy?
Answers
45.00x +17.99 = 422.99 (Setup Equation)
45.00x = 405 (Subtract 17.99 from both sides)
x = 9 (Divide both sides by 45.00)
Answer:
9
Step-by-step explanation:
First, you write out the equation. We don't know how many tickets Eva bought, so it can be represented by x. Each ticket costs 45 dollars. The amount of tickets times 45 plus the fee will equal 422.99, so the equation will look like this:
45x + 17.99 = 422.99
Subtract 17.99 from both sides:
45x = 405
Divide 45 on both sides:
x = 9
Eva bought 9 tickets

A Pizza restaurant offers the following deals”
Deal #1: $8.99 for one large pizza and $5 for each additional large pizza on the same order
Deal#2: $6.00 per large pizza
At what number of pizzas does Deal #1 become a better deal?
What is the cost of 10 pizzas for each deal?
What is the cost per pizza in Deal #1? Which is the better deal and why?
Answers
Answer:
The least number of pizza make deal 1 better than deal 2 is 4
The cost of deal 1 is $53.99 and the cost of deal 2 is $60
The cost per pizza of deal 1 is $5.399
The better deal is deal 1
Step-by-step explanation:
* Deal 1 becomes better if it costs less than deal 2
- Assume that the number of pizza are n
* Deal 1:
∵ The cost of one large pizza = $8.99 for first 1 and = $5 for each
additional one
∵ They ordered n large pizza
∴ The cost = 8.99 + 5(n - 1)
- Multiply the bracket by 5
∴ The cost = 8.99 + 5n - 5
- Add like terms
∴ The cost = 3.99 + 5n
∴ The cost of deal 1 = 3.99 + 5n
* Deal 2:
∵ The cost of any large pizza is $6
∵ They ordered n large pizza
∴ The cost = 6 × n = 6n
∴ The cost of deal 2 = 6n
- We need Deal 1 better than deal 2
- Then, put the cost of deal 1 < the cost of deal 2
∵ 3.99 + 5n < 6n
- Subtract 5n from both sides
∴ 3.99 < n
∴ n > 3.99
∴ n = 4
* The least number of pizza make deal 1 better than deal 2 is 4
∵ n = 10
∴ The cost of deal 1 = 3.99 + 5(10) = 53.99
∴ The cost of deal 2 = 6(10) = 60
* The cost of deal 1 is $53.99 and the cost of deal 2 is $60
∵ The cost per one pizza = total cost ÷ the number of pizza
∴ The cost per pizza of deal 1 = 53.99 ÷ 10 = 5.399
* The cost per pizza of deal 1 is $5.399
∵ The unit price of deal 1 is $5.399
∵ The unit price of deal 2 is $6
∵ $5.399 < $6
∴ The unit rate of deal 1 is less than the unit price of deal 2
* The better deal is deal 1
Deal #1 becomes a better deal at 4 pizzas. The cost of 10 pizzas for Deal #1 is $43.99, and for Deal #2 is $60.00. The cost per pizza in Deal #1 is $8.99 for the first pizza and $5 for each additional pizza. Deal #1 is the better deal when ordering 4 or more pizzas because the cost per pizza decreases as more pizzas are added to the order.
To determine at what number of pizzas Deal #1 becomes a better deal than Deal #2, we need to compare the total cost of pizzas under each deal.
For Deal #1, the cost structure is as follows:
The first pizza costs $8.99.
Each additional large pizza on the same order costs $5.
For Deal #2, the cost is a flat rate of $6.00 per large pizza.
Let's first find out at what point the total cost of pizzas under Deal #1 equals the total cost under Deal #2. We'll denote the number of additional pizzas (after the first one) as 'n'.
The total cost for Deal #1 can be expressed as:
[tex]\[ C_1 = 8.99 + 5n \][/tex]
The total cost for Deal #2 is:
[tex]\[ C_2 = 6(n + 1) \][/tex]
We set [tex]\( C_1 \) equal to \( C_2 \)[/tex] to find the break-even point:
[tex]\[ 8.99 + 5n = 6(n + 1) \][/tex]
[tex]\[ 8.99 + 5n = 6n + 6 \][/tex]
[tex]\[ 8.99 - 6 = 6n - 5n \][/tex]
[tex]\[ 2.99 = n \][/tex]
Now let's calculate the cost of 10 pizzas for each deal:
For Deal #1:
[tex]\[ C_{10} = 8.99 + 5(10 - 1) \][/tex]
[tex]\[ C_{10} = 8.99 + 5 \times 9 \][/tex]
[tex]\[ C_{10} = 8.99 + 45 \][/tex]
[tex]\[ C_{10} = \$43.99 \][/tex]
For Deal #2:
[tex]\[ C_{20} = 6 \times 10 \][/tex]
[tex]\[ C_{20} = \$60.00 \][/tex]
The cost per pizza in Deal #1 is $8.99 for the first pizza and $5 for each additional pizza. As the number of pizzas increases, the average cost per pizza decreases.

A store is having a sale on trail mix and jelly beans. For 2 pounds of trail mix and 3 pounds of jelly beans, the total cost is 13. For 4 pounds of trail mix and 8 pounds of jelly beans, the total cost is $33. Find the cost for each pound of trail mix and each pound of jelly beans.
Answers
Answer:
trail mix: $1.25jelly beans: $3.50 per poundStep-by-step explanation:
The difference between double the first purchase and the second purchase is $7 and 2 pounds of jelly beans. Hence a pound of jelly beans is $3.50.
(4t +8j) -2(2t +3j) = (33) -2(13) . . . . . let t and j represent pounds of trail mix and jelly beans, respectively
2j = 7 . . . . . . . . . . simplify
j = 7/2 = 3.50
Using that value in the first purchase, we get ...
2t +3(3.50) = 13
2t = 13 -10.50
t = 2.50/2 = 1.25
A pound of trail mix is $1.25.
Find the exact circumference of a circle with diameter equal to 8 ft. 8 ft. 16 ft. 64 ft.

ANSWER
8π ft
EXPLANATION
The circumference of a circle is calculated using the formula C=πd.
Where d=8 is the diameter of the circle.
We substitute d=8 into the formula to obtain,
C=8π ft.
Because we are looking for the exact circumference, we leave the answer in terms of π.
Answer:
The correct answer is,
circumference = 8π feet
Step-by-step explanation:
Formula:-
Circumference of a circle = 2πr
Or circumference = πd
Where 'r' is the radius of circle and 'd' is the diameter of circle
It is given that, diameter of circle is 8 feet
To find the circumference
Here d= 8 feet
Circumference = πd = π * 8 = 8π feet

b. [tex]\( 1 \frac{1}{2} \div \frac{1}{2} \):[/tex]This would divide 1 1/2 hours by 1/2, which is not what we need.
c. [tex]\( \frac{1}{2} \times 1 \frac{1}{2} \):[/tex]This is the correct operation, as it multiplies 1 1/2 hours by 1/2 to find half of the time.
d.[tex]\( \frac{1}{2} + 1 \frac{1}{2} \):[/tex] This would add 1/2 hour to 1 1/2 hours, which is not what we need.
So, the correct equation to find the amount of time they spent swimming laps is:
[tex]c. \( \frac{1}{2} \times 1 \frac{1}{2} \)[/tex]
Let's calculate it:
[tex]\[\frac{1}{2} \times 1 \frac{1}{2} = \frac{1}{2} \times \frac{3}{2} = \frac{3}{4} \text{ hours}\][/tex]
Therefore, Paul and Krystal spent [tex]\( \frac{3}{4} \)[/tex] hours (or 45 minutes) swimming laps.
