Here is trapezoid A in the coordinate plane:
If you drew Trapezoid B, the image of A after a 90\circ∘ rotation clockwise, using the origin as the center of rotation, what would be the coordinates of each of the vertices?
Answers
Answer:
(1,-2) (3,-2) (4,-4) (1,-4)
Step-by-step explanation:
First of all I noted that the origin would be the centre of rotation.
Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point
Then I drew a line from the point (2,1) to the centre of rotation (the origin)
From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).
I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.
From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.
Then I just drew in the other points to make the rest of the shape.
Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you
The required coordinate of the image of the rotation of the trapezoid (1, -2) (3, -2) (4, -4) (1, -4)
Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.
The graph is a demonstration of curves which gives the relationship between the x and y-axis.
Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).
Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

Select all ratios equivalent to 2:3.
Answers
Answer:
12:18 and 10:12 (i think)
Step-by-step explanation:
After converting the given ratios in their simplest form, the equivalent form of 2:3 we get 12:18.
To find the simplest form of a fraction, you have to simplify the numerator and denominator to their lowest terms and keep dividing until you can no longer simplify the fraction any further.
The given ratios are,
12:18,
3:21,
10:12
For the ratio 12:18,
Simplify it by finding the greatest common divisor (GCD) of 12 and 18.
The GCD of 12 and 18 is 6.
By dividing both numbers by 6, we get the smallest ratio of 2:3.
Moving to the ratio of 3:21,
Find the GCD of 3 and 21, which is 3.
Dividing both numbers by 3 results in the smallest ratio of 1:7.
Find the smallest ratio for 10:12.
The GCD of 10 and 12 is 2.
Dividing both numbers by 2 gives us the smallest ratio of 5:6.
Hence, the simplest form of ratios for the given ratios are:
12:18 = 2:3,
3:21 = 1:7,
10:12 = 5:6.
Hence,
The ratio equivalent to 2:3 is 12:18.

Which of the following equations is equivalent to
Answers
Answer:
Step-by-step explanation:
[tex]\frac{x+3}{3} =5- \frac{x-3}{6} \\(\frac{x+3}{3}) *6 =5 - (x-3)[/tex]
[tex]2x+6 = 5 - x+3[/tex]
Answer:
none
Step-by-step explanation:
We can start by multiplying both side of the equation by 6 in order to remove the fractions.
[tex]6*\frac{x+3}{3} = 6(5 - \frac{x-3}{6})[/tex]
[tex]2(x + 3) = 30 - 6*\frac{x-3}{6}[/tex]
[tex]2x + 6 = 30 -(x - 3)[/tex]
[tex]2x + 6 = 30 - x + 3[/tex]
Now, we can try to see if this equation is equivalent to the other options.
Every option has the left side as 2x - 6. In order to get that, we need to subtract 12 on both sides:
[tex]2x - 6 = 30 - x + 3 - 12[/tex]
This simplifies to
[tex]2x-6 = 18 - x + 3[/tex]
This is not the same as any of the options shown.
We can check this by solving the equations.
2x - 6 = 18 - x + 3
3x = 6 + 18 + 3
3x = 27
x = 9
Now, the first option:
2x - 6 = 10 - x - 3
3x = 6 + 10 - 3
3x = 13
x = 13/3
The second option is the exact same as the third, so they would have the same solution:
2x - 6 = 30 - x- 3
3x = 6 + 30 - 3
3x= 33
x = 11
Since none of the options have the answer 9, they are not equivalent to the equation shown.

Jordan has to solve this division problem: 42 divided by 7 = ?
Which of the following equations can he use?
42 + 7 = ?
7 x 42 = ?
? x 7 = 42
7 divided by 42 = ?
Answers
The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:
? x 7 = 42
So, the correct equation is option 3) ? x 7 = 42.
Given that, Jordan has to solve this division problem: 42 divided by 7 = ?
In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.
Therefore, he can use the equation:
? x 7 = 42
This equation represents the inverse operation of division, which is multiplication.
When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).
By solving for the missing factor, he will find the correct answer to the division problem:
The missing factor = 42 / 7 = 6
So, the correct equation is option 3) ? x 7 = 42.

A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Answers
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
