Find the scale factor of the similar shapes below.
Answer:
x=12 and the scale factor is 1.5
Step-by-step explanation:
From D' to F' is 7.5 and from D to F is 5cm the difference is 2.5. From F' to E' is x and from F to E is 8. This is just understanding what you can see. You find x by figuring out the ratio from 5 to 7.5 is and 8 to x or vise versa. It depends which way you are going. I think you are going from E,D,F to E',D',F'. So from 5cm to 7.5 cm. This is 1.5 because you are dividing 7.5/5. If you needed to find x, it would be 12.
Probability of picking 2 marbles without looking out of a bag containing 2 red marbles, 2 blue marbles, and 2 white marbles. What is the probability that you will choose a red marble and then a blue marble without replacing the red one?
Answer: 2/15
Step-by-step explanation:
2 red
2 blue
2 white
6 total
2/6 chance of getting red (1/3)
2/5 chance of getting blue next
2/5*1/3 = 2/15

what is the equation for the line?
Answer:
y=6/5x+8/5
Step-by-step explanation:
find the slope (6/5) you can find this by making a slope triangle between the 2 points.
now, plug in a point to y=6/5x+b
-2=6/5(-3)+b
-2=-18/5+b
-10/5=-18/5+b
b=8/5 (y-int)
so y=6/5x+8/5

a circle is drawn in a coordinate plane centered at (8,15) and a radius of 3 units.
Answer:
(x - 8)² + (y - 15)² = 9
Step-by-step explanation:
Assuming you want the equation.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (8, 15 ) and r = 3 , then
(x - 8)² + (y - 15)² = 9
Question 4: *
What are the solutions to the equation 4x2 – 52x + 169 = 121?
Answer:
1.0769
Step-by-step explanation:
multiply 4x2 to get 8
move -52x over the equal sign to make it 52x
so we get something like this: 8 + 169 = 121 + 52x
also move 121 over the equal sign to make it -121
Like this: 8 + 169 - 121 = 52x
Now when you simply, you will get 56 = 52x
Divide both sides by 52
Final answer is 1.0769

Triangle JKL has vertices J(0, 2), K(–1, 2), and L(0, –3). What are the coordinates of the image of point J after a dilation with a scale factor of 3?
Given:
The vertices of a triangle JKL are J(0, 2), K(–1, 2), and L(0, –3).
To find:
The coordinates of the image of point J after a dilation with a scale factor of 3.
Solution:
If a figure is dilated by a scale factor of k, then
[tex](x,y)\to (kx,ky)[/tex]
The given triangle JKL dilated by a scale factor of 3. So,
[tex](x,y)\to (3x,3y)[/tex]
The coordinates of point J are J(0,2). By using the above rule, we get
[tex]J(0,2)\to J'(3(0),3(2))[/tex]
[tex]J(0,2)\to J'(0,6)[/tex]
Therefore, the coordinates of the image of point J after a dilation with a scale factor of 3 are J'(0,6).

Step-by-step explanation:
(3 / 4) / 3 =
3 / 4 x 1 / 3 =
3 / 12 =
1/4 ton
Can someone please help me with math.
Answer:
A
Step-by-step explanation:
So lets look at the points on the graph.
Actually, lets just look at a and b(We only need 1 of these points, but it doesnt hurt to do a little extra to udnerstand it better)
If we count the coordinates for A, we get:
(-2, 3)
Remember, we need to use a scale factor of 2 for this.
So we need to multiply by 2.
This now gets us:
(-4. 6)
This looks like answer A, which has: (-4, 6) for A coordinates.
Now, lets check this with B coordinates:
(1, 3)
Multiply by 2:
(2, 6)
For answer A, is this the B coordinates?
Yup, answer A has B coordinates (2, 6)
So the answer is A!
Hope this helps! :)
Here is a list of numbers:
18, -4, -3, -19, 11, 1, -16 ,15 ,9 ,5
State the median.
Answer:
6
Step-by-step explanation:
To find the median you simply look for the number in the middle of the list.
In this particular case 1 and 11 are both the fifth number in the series of numbers. When this happens you have to add the two terms together (1+11) and divide by two (12/2)=6
