For the first question, we can extend all of the lines on the trapezoid, and triple the distance from B on the line, so we can use the fact that B is (2, 2), A is (0, 0), C is (4, 2), and D is (6, 0) to get that the new coordinates are A (-4, -4), B (2, 2), C (8, 2), and D (14, -4).

For the second question, notice that we are changing the size on the same line, and every side length is tripled by 3. If every side length is tripled by 3, then the perimeter of the new image is triple the perimeter of the original.

Jane will spin the spinner below 30 times. How many times would Jane expect it to land on an even number? the numbers on the spi

Sedbober [7]

Answer:

below 15 times

Step-by-step explanation:

If the numbers on the spinner are 1, 2, 3, 4, 5, 6 (six numbers) the even numbers are 2, 4, 6 ( three numbers) than 3 out of 6 numbers on the spinner are even.

If Jane will spin the spinner below 30 times the is expected that less than half of the time 30/2 = 15 times will be an even number.

Help pls help <br> It’s a grade

The first option is correct.

You could do all the math to compare the final answers, but I looked at the part where you add. Using a standard algorithm, when going on to the next digit in the second number, you always add a 0 first. The rest of those options don't include a 0.

I'm really not sure how to go about solving this algebraic equation, please help! .513 = (2x)^2 / (.05-x)

LiRa [457]

Let's set it up like this:
$0.513=\frac{\left(2x\right)^2}{\left(0.05-x\right)}$
Multiply both sides by $0.05-x$
$0.513\left(0.05-x\right)=\frac{\left(2x\right)^2}{0.05-x}\left(0.05-x\right)$
$0.513\left(0.05-x\right)=4x^2$
We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:
$x=-\frac{0.513+\sqrt{0.673569}}{8},\:x=\frac{\sqrt{0.673569}-0.513}{8}$
The variable $x$ can be both positive or negative.
We have found successfully our answer.

Let me know if you have any questions regarding this problem!
Thanks!
