So this one really confuses me, it may be easy for you guys though. So, a magical square 3x3 with 8 numbers 1/4 - 2 going by fractions, so, 1/4, 2/4, 3/4, 1, 1 1/4, 1 2/4, 1 3/4, 2. Each side has to equal 3. Good luck, I've spent 2 hours now.

Step-by-step explanation:

Ok so I was looking at what the other answer said and it doesn’t really work for this because that uses 9 numbers, this has 8. My work is in whole numbers but it’s all equivalent to the numbers you gave if you make it 4ths ex. 5=5/4=1 1/4 or 8=8/4=2

During two games, the number of points scored by a basketball team increased from 75 to 87. By what percentage did the number of points scored increase?
A - 12%
B - 14%
C - 86%
D - 16%

Answers

Answer:

D 16% increase

Step-by-step explanation:

This is ez

just did this stuff in pre algebra

The solution is Option D.

The percentage of increase in number of points is 16 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The number of points scored by the basketball team = 75

The increased points scored by the basketball team = 87

The increase in points =

increased points scored by the basketball team - number of points scored by the basketball team

The increase in points = 87 - 75

                                      = 12 points

So , the percentage increase in points = ( increase in points / number of points scored by the basketball team ) x 100

The percentage increase in points = ( 12 / 75 ) x 100

                                                          = 0.16 x 100

                                                          = 16 %

Therefore , the percentage increase is 16 %

Hence , the percentage of increase in number of points is 16 %

The point (7, 0) is reflected over the x-axis. What do you notice about the coordinates of the reflected point? Why is this?

Answers

Answer:

The coordinate stayed the same

Step-by-step explanation:

because when you reflect on the x-axis, the x-axis stays the same while the y-axis gets flipped. in this case, the coordinate is on the y-axis, or the y-axis is 0, and you can't flip 0 to get an opposite. the opposite of 0 is 0, so he coordinate stayed the same.

The value of reflected point is, (7, 0)

And, Any point on the line of reflection is invariant

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The point (7, 0) is reflected over the x-axis.

Hence,

The point (7, 0) becomes the point (7, 0) when reflected over the x-axis. That is, its coordinates do not change.

And, The point (7, 0) lies on the x-axis, so is on the line of reflection. Any point on the line of reflection is invariant--it doesn't move.

Hence, The transformation for reflection in the x-axis is ...

 (x, y) ⇒ (x, -y)

 (7, 0) ⇒ (7, 0) . . . . . . the opposite of 0 is 0

Thus, The value of reflected point is, (7, 0)

And, Any point on the line of reflection is invariant
