Parallel lines are preserved in:
Reflections, Translations & Rotations
Parallel lines maintain their geometric property of not intersecting through all three transformations: rotations, reflections, and translations. Therefore, the correct answer is Option B. l, II, and III.
Explanation:In the field of mathematics, particularly in geometry, transformations involve the manipulation of shapes while preserving their essential properties. In the case of parallel lines, their key property is that they do not intersect, regardless of their length.
Out of the transformations listed - rotations, reflections, and translations - parallel lines are preserved in all three. Therefore, your answer is Option B. l, II, and III.
Specifically, a rotation spins the figure around a fixed point, a reflection flips the figure over a line, and a translation slides the figure along a straight line, parallel to the original lines. In all these transformations, the lines remain parallel to each other.

a soccer team played 47 games and won 33.Rounding to the nearest whole number,what percent of its games did the team win?
Answer:
70%
Step-by-step explanation:
1. divide the number of games won (33) by the total number of games (47)
33/47 = 0.702
2. Move the decimal two places to the right = 70.2%
3. round down to 70%
Final answer:
The soccer team won 70% of its games after calculating the fraction of games won, converting it to a decimal, then to a percent, and finally rounding to the nearest whole number.
Explanation:
To calculate the percent of games won by the soccer team, we divide the number of games won by the total number of games played and then multiply by 100 to convert the fraction to a percentage.
Step 1: Find the fraction of games won: 33 (games won) ÷ 47 (total games).
Step 2: Convert the fraction to a decimal: 33 ÷ 47 = 0.7021.
Step 3: Convert the decimal to a percent: 0.7021 × 100 = 70.21%.
Step 4: Round to the nearest whole number: 70.21% rounded to the nearest whole number is 70%.
Therefore, the soccer team won 70% of its games.
A picture on the wall in Jeremy’s classroom has 4 right angles,4 sides of equal length,and 2 pairs of opposite sides that are parallel.What quadrilateral best describes the picture?
The answer is: A square.
Why?The quadrilateral is a square since:
- It has four right angles, squares have four right angles (90°), giving a total of 360° if you sum all of them.
- It has four equal sides, squares have four sides of equal length.
- It has two pairs of opposite sides that are parallel, if we look for a side of a square, we will find an opposite side which is parallel, so, squares have two pairs of opposite sides that are parallel.

Step-by-step explanation:
If two chords intersect externally, then the product of the length of the chord and the length of the part outside the circle is a constant.
Thus from the figure,
we can deduce that:
8×3=6×x
collecting the like terms together we get:
24=6x
x=4
Answer:
x =4
Step-by-step explanation:
Refer the attached figure:
We will use Intersecting secants theorem
Theorem : When two secant lines intersect each other outside a circle, the products of their segments are equal. i.e. [tex]a\times b = c \times d[/tex](refer the attached figure)
So, using this theorem
[tex]x \times 6 = 3 \times 8[/tex]
[tex]x = \frac{24}{6}[/tex]
[tex]x = 4[/tex]
Hence the value of x is 4.

Tico's Taco Truck is trying to determine the best price at which to sell tacos, the only item on the menu,
to maximize profits. The taco truck's owner decides to adjust the price per taco and record data on the
number of tacos sold each day with each new price. When the taco truck charges $4 for a taco, it sells
an average of 60 tacos in one day. With every $1 increase in the price of a taco, the number of tacos
sold per day decreases by 7. The owner can calculate the daily revenue using the polynomial
expression -7x2 + 32x + 240, where x is the number of $1 increases in the taco price. In this activity.
you'll interpret and manipulate this expression and the scenario it represents.
Part A
What is the constant term in the polynomial expression -7x2 + 32x + 240, and what does it
represent?
The constant term is "240." The number represents the daily revenue when the price of a taco is 0 dollars.
Answer:
The constant term is 240. It represents the initial daily revenue.
Step-by-step explanation:
It is given that Tico's Taco Truck is trying to determine the best price at which to sell tacos, the only item on the menu, to maximize profits.
The owner can calculate the daily revenue using the polynomial expression
[tex]-7x^2+32x+240[/tex]
where x is the number of $1 increases in the taco price.
Constant term does not contain any variable.
In the given expression 240 is free from variable x. So, the constant term is 240.
The value of expression is 240 for x=0. Since x is the number of $1 increases in the taco price, therefore 240 is the daily revenue when the taco price is not increased or the taco price increased by 0.
Therefore the constant term is 240 and it represents the initial daily revenue.

9340.00 is invested into an account that earns 8 1/2% simple interest for 15 years. What is the interest earned and what is the total in the account?
The amount of interest earned is $11908 and the total amount is $21248.
What is simple interest?Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.
Given that 9340.00 is invested into an account that earns 8.5% simple interest for 15 years.
The simple interest will be calculated by the formula below,
Simple interest = ( P x R x T ) / 100
Simple interest = ( 9340 x 8.5 x 15 ) / 100
Simple interest = $11908.5
The total amount will be,
Amount = $11908.5 + $9340
Amount = $21248.5

The simple interest earned on an investment of $9340.00 at a rate of 8.5% over 15 years is $11919.00. The total amount in the account after 15 years is $21259.00.
To calculate the simple interest earned on an investment, you can use the formula I = P × r × t, where I is the interest, P is the principal amount, r is the interest rate (in decimal form), and t is the time in years . In this case:
r (Interest Rate) = 8.5% or 0.085 (since 8 1/2% is the same as 8.5%)
t (Time) = 15 years
Using the formula:
I = $9340.00 × 0.085 × 15 = $11919.00
The total simple interest earned over 15 years would be $11919.00. To find the total amount in the account after 15 years, we add this interest to the original principal:
Total = Principal Amount + Interest
Total = $9340.00 + $11919.00 = $21259.00
Therefore, the total in the account after 15 years will be $21259.00.

(b) What do you know about the two lines in this system of equations?
Answer:
Part a) In the procedure
Part b) Line A and Line B are different parallel lines
Step-by-step explanation:
Part a) we have
[tex]3x-6y=-12[/tex] ----> equation A
[tex]x-2y=-8[/tex] ----> equation B
Isolate the variable x in the equation B
[tex]x=2y-8[/tex]
Substitute the value of x in the equation A
[tex]3(2y-8)-6y=-12[/tex]
[tex]6y-24-6y=-12[/tex]
[tex]-24=-12[/tex] ------> is not true
therefore
The system of equations has no solutions
Part b) What do you know about the two lines in this system of equations?
[tex]3x-6y=-12[/tex] ------> equation A
isolate the variable y
[tex]6y=3x+12[/tex]
[tex]y=(1/2)x+2[/tex]
[tex]x-2y=-8[/tex] -------> equation B
isolate the variable y
[tex]2y=x+8[/tex]
[tex]y=(1/2)x+4[/tex]
Line A and Line B are parallel lines, because their slopes are the same
Line A and Line B are different lines because their y-intercept is not the same
Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. Then she used 3/4 of the remainder to make a salad. What fraction of the tomatoes did mrs Jenkins use to make the salad?
Answer:
Final answer is 1/3.
Step-by-step explanation:
Question says that Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. After that she used 3/4 of the remainder to make a salad. Now we need to find about what fraction of the tomatoes did Mrs Jenkins use to make the salad.
As she used 5/9 of the tomatoes to make pasta sauce.
Now remaining amount of tomatoes = 1- 5/9 = 9/9 -5/9 = 4/9
Then she used 3/4 of the remainder to make a salad. So fraction of the tomatoes did Mrs Jenkins use to make the salad = (4/9)(3/4)=12/36=1/3
Hence final answer is 1/3.

a motorboat maintains a constant speed of 38 miles per hour. it takes 30 minutes to travel upstream and 27 minutes back. what is the speed of current?
Answer:
r = 2 [stream's speed is 2 mph downstream
Step-by-step explanation:
Remark
The distances traveled [upstream and downstream] are the same.
If it takes longer to go upstream, it means the speed of the current is going against him. So the rate is 38 - r where r is the speed of the current.
The rate of the downstream is 38 + r because it takes him less time to go downstream and the current is helping him go.
The times are given
Givens
Time Upstream = 30 minutesTime Downstream = 27 minutesDistance upstream = d1Distance downstream = d2rate upstream: 38 - rrate downstream: 38 + rd1 = d2Formula
d1 = d2
d1 = (38 - r) * 30
d2 = (38 + r) *27
(38 - r) * 30 = (38+r)*27
Solution
Remove the brackets on both sides.
38*30 - 30*r = 38*27 + 27r Add 30r to both sides
38*30 - 30r + 30r =38*27 + 27r + 30r Combine the numbers
1140 = 1026 + 57r Subtract 1026 from both sides.
114 = 57r Divide by 57
114/57 = 57r/57
r = 2
Cube A has a side length of 3 meters and cube B has a side length of 6 meters. Calculate the volume of the two cubes. Which statement accurately represents the relationship between the two volumes? A) The volume of cube A is half the volume of cube B. Eliminate B) The volume of cube B is 4 times the volume of cube A. C) The volume of cube B is 6 times the volume of cube A. D) The volume of cube B is 8 times the volume of cube A.
Answer: The correct answer is choice D.
Step-by-step explanation: In order to answer this question you need to calculate the volume of each of the cubes.
Cube A has a side which is 3 meters, so the volume = 3 x 3 x 3 = 27
Cub B has a side which is 6 meters, so the volume = 6 x 6 x 6 = 216
216/27 = 8. Therefore, the volume of cube B is 8 times the volume of cube a.
The volume of cube A is 27 cubic meters and the volume of cube B is 216 cubic meters. Cube B's volume is 8 times greater than cube A's. The correct answer is option D)
Explanation:The volume of a cube is calculated by cubing the length of its side. So, the volume of cube A is 3 meters x 3 meters x 3 meters = 27 cubic meters. The volume of cube B is 6 meters x 6 meters x 6 meters = 216 cubic meters. Comparing the volumes, cube B's volume is 216/27 = 8 times greater than the volume of cube A. Therefore, the statement that accurately represents the relationship between the two volumes is option D) The volume of cube B is 8 times the volume of cube A.

Step-by-step explanation:
y = x + 2 x + y = 3

x + (x + 2) = 3
2x + 2 = 3
2x = 1
x = [tex]\dfrac{1}{2}[/tex]

Answer:
x = 1/2
y = 5/2
Step-by-step explanation:
So we're gonna use the elimination method, by eliminating one of x or y to find the value of the other one.
y = x + 2 --------------(1)
x + y = 3 --------------(2)
In (1), x is in LHS and y is in RHS. To make things simpler, we take both x and y to the same side.
y = x + 2
y - x = x + 2 - x ( take x to the other side)
y - x = 2-------------------------(3)
Note that in (2), x is positive and in (3), x is negative. So by adding these two, we can single out y because +x and -x cancels out. So we can eliminate x.
(3) + (1) : (x+y) + (y- x) = 3 + 2
2y = 5
y = 5/2
Substituting y = 5/2 for (1),
5/2 - x = 2
5/2 = 2 + x
5/2 - 4/2 = x
x = 1/2
∴ x = 1/2
y = 5/2
