Describe a sequence of transformations that take isosceles trapezoid T to its image T'
Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above
Step-by-step explanation:
Transformation involves changing the position of a shape
The transformation from T to T' is a 90 degree counterclockwise
From the figure, we can see that:
The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of TThis means that:
A 90 degree counterclockwise through point D will take trapezoid T to T'
Hence, the required transformation is a 90 degree counterclockwise through point D

A civil engineer wants to know the opinions of drivers about online driving tests. She obtains a list of 730 drivers who have recently completed an online driving course and e-mails a questionnaire to a randomly selected group of 200 of these drivers. Only 102 of the questionnaires are returned. Identify the population and the sample in this study. (4 points)
The population is 200 and the sample is 102.
The population is 730 and the sample is 200.
The population is 102 and the sample is 730.
The population is 730 and the sample is 102.
The population is 200 and the sample is 730.
Answer: The population is 730 and the sample is 102.
Step-by-step explanation:
When we have a given set of elements, N elements, the population is N.
And if we do statistics with A of these N elements, the sample is A.
In this case, the population is the set of the 730 drivers, then the population is 730.
And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).
Then the sample will be 102.
Then the correct option is:
The population is 730 and the sample is 102.
Answer:
730 and 102.

Jim drove 756 miles in 12 hours.
At the same rate, how many miles would he drive in 7 hours?
Answer:
441
Step-by-step explanation:
Use a proportion.
756 miles is to 12 hours as x miles is to 7 hours
756/12 = x/7
12x = 7 * 756
12x = 5292
x = 441
Answer: 441 miles
Answer:
441
Step-by-step explanation:
756 divided by 12 = 63
Jim drives 63 miles in 1 hour
Multiply 63 by 7
63 ⋅ 7 = 441
Jim will drive 441 miles in 7 hours

Answer: B
Step-by-step explanation:
We have to find the amount that Maya painted IN ALL, which means we must add 3/4 and 1/8. First, look for the answer choice that has 1/8 as a number (B and A). However, none of the answer choices have 3/4 as an answer, so we must convert it into an equivalent fraction, 6/8. You get 6/8 by multiplying both the numerator and denominator by 2. Therefore the answer is B.

Which equation is equivalent to 2x + 3y = 12?
y=2/3x+4
y= -2/3x+12
y= -2/3x+4
y=2/3x+12
Answer:
y= -2/3x + 4
Step-by-step explanation:
2x + 3y = 12
3y = 12 - 2x
3y/3 = 12/3 - 2x/3
y = 4 -2x/3

Which statement is true regarding the graphed functions? ((help please :,)
Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)
Answer:
Answer:
(5, 20)
Step-by-step explanation:
We can find the slope of the line
m = (y2-y1)/(x2-x1)
= (40-0)/(10-0)
= 40/10
=4
Since the line goes through (0,0) the y intercept is 0
y = mx+b
y = 4x
Lets check the points by substituting into the equation
40, 10) 10 = 4*40 10 =160 no
(–5, –10) -10 = 4*-5 10 = -20 no
(5, 20) 20 = 4*5 20 = 20 yes
(–10, –20) -20 = 4*-10 -20 = -40 no
Step-by-step explanation:

A school is planning a fundraiser with all profits going to charity. The amount of profit is found by subtracting the total cost from total ticket sales.
Ticket Sales: 200x−10x2
Event Cost: 500+20x
If x represents the price of a ticket, what ticket prices will result in a profit of $200 or more? Express your answers rounded to the nearest cent.
A
$5.69≤x
B
$5.69≤x≤$12.33
C
$3.29≤x
D
$3.29≤x≤$21.29
Please help.
The value of the x should be more than or equal to 5.69. Then the correct option is A.
What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.
A school is planning a fundraiser with all profits going to charity.
Ticket Sales: 200x − 10x²
Event Cost: 500 + 20x
The amount of profit is found by subtracting the total cost from total ticket sales. A profit of $200 or more.
Event cost − Total sales ≥ Profit
(500 + 20x) − (200x − 10x²) ≥ 200
− 200x + 10x² + 500 + 20x − 200 ≥ 0
10x² + 180x − 700 ≥ 0
10x² − 180x + 700 ≥ 0
x² − 18x + 70 ≥ 0
On simplifying, we have
(x − 5.69) (x − 12.33) ≥ 0
x ≥ 5.69, 12.33
Thus, the value of the x should be more than or equal to 5.69. Then the correct option is A.

Equivalent or Not?
Sarah thinks that the following
expressions are equivalent:
2x + 3 = x/2 + 4
Is she correct? If so, prove that these
two expressions are equivalent. If not,
explain what errors she made.
Answer:
equivalentStep-by-step explanation:
2x + 3 = x/2 + 4
2x - x/2 = 4 - 3
3x/2 = 1
x = 1 (2) / 3
x = 2/3
substitute the value of x=2/3 back into the equation:
2(2/3) + 3 = (2/3)/2 + 4
4/3 + 3 = 1/3 + 4
13/3 = 13/3 both are equal if x=2/3!!!BRAINY AND 10 PTS!!!

It will beat 325 times in how many minutes?
I
Answer: 13 minutes
Step-by-step explanation: common sence every minute the heart beats 25 times so 25 times 3 equals 75 so if that s true then 25 times 13 equals 325 ;)
Answer:
12.99 - 13 min.Step-by-step explanation:
It is 12.99 - 13 min. because 325 divided by 75
equals 4.33 and so on. If you times 4.33 by 3
you get 12.99, if your teacher said to round it
then do 13 Min. Hope this helps! <3

can some one solve this its subtitution i need the brainlyist i will give yo a thanks a five star and brainlyist
Step-by-step explanation:
Hey there!
Given;
The equations are;
y = 8x...........(i)
y = 2x-12..........(ii)
Now;
Substituting the value of "y" from equation (i).
8x = 2x-12
8x-2x = -12
6x = -12
X = -12/6
Therefore, X= -2.
Now; Substituting the value of "y" in equation (i)
y = 8*-2
y = -16
Therefore, y= -16.
Therefore, x= -2 and y= -16.
Check:
y = 2x
-16= 8*-2
-16 = -16 (true).
Hope it helps...
