Which Point Is A Reflection Of (1.5, -4.5) Across The X-axis And The Y-axis?A. Point IB. Point JC. Point

Answers

Answer 1

Answer:

(1.5, 4.5 ) and (- 1.5, - 4.5 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

(1.5, - 4.5 ) → (1.5, 4.5 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

(1.5, - 4.5 ) → (- 1.5, - 4.5 )

If x- axis then y- axis

(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

You select a marble without looking and then put it back. If you do this 5 times, what is the best prediction possible for the number of times you will pick a pink marble?

Answers

Since the ratio of pink marbles to other marbles is 1:5 meaning only 1 pink marble for every five you pick usually, the number of times you might pick a pink marble is 1 if you did it 5 times.

Answers

Answer:

7 units from (-3,2)(,2)and(,2)

Step-by-step explanation:

The purpose of this task is for students to solve a mathematical problem using points in the coordinate plane. This task also helps lay the foundation for understanding operations on signed numbers without formally introducing those notions, which are not expected until 7th grade (see 7.NS.1). Students will not have the full machinery needed to find distances between two arbitrary points in the plane until they have studied the Pythagorean Theorem in 8th grade. However, it is straightforward for them to find horizontal and vertical distances, which mirrors how one might represent sums and differences of signed numbers on a number line. The solution for the first part shows how these questions can be represented using absolute values (as described in standard 6.NS.C.8), although students are unlikely to make this connection without being asked to do so. If students are asked to solve this problem on their own first, it could be used to launch a discussion of the relationship between the the absolute value of coordinates of points in the plane and their distance to the respective axes.

Please note that students will have to assume that the points have integer coordinates, which is reasonable but worth mentioning.

Solution

The distance between points B and C is 5 units, as indicated below.

We can determine the distance between points B and C by counting the units between the two points since they are on the same vertical line which happens to be a grid line.

We can also note that the coordinates for B are (3,2) and so it is |2| units above the x-axis. Similarly, the coordinates for C are (3,−3), so it is |-3| units below the x-axis. Thus, the distance between B and C is

|2|+|−3|=5

units.

The distance between points D and B is 7 units, as indicated below.

The distance between points D and E is 4 units, as indicated below.

Point C is the only one of points A,…E that is both 4 units away from (−1,−3) and 2 units away from (3,−1). There is another point that satisfies these two criteria (which is the other intersection point of the circle of radius 4 and circle of radius 2 shown below), but it does not have integer coordinates and is not one of the points identified in the task

Archer Middle School has 78 students playing soccer this year. This number is 6 more than 3 times the number of students who played last year. Let n represent the number of students who played last year. Which equation expresses an equality between two different ways of expressing the number of students who are playing soccer this year?

A: n + 6 = 78
B: 3n + 6 = 78
C: n - 6 = 78
D: 3n - 6 = 78

Answers

The answer is B. This is because we know this is 6 more than 3 times the number of students that played last year. A and C makes no sense. D does not make any sense because it is 6 more not 6 less.

Describe how to subtract a decimal from a whole number. Use 15 - 12.75 as an example, and determine its solution.

Answers

Answer:

2.25

Step-by-step explanation:

15.00

-12.75

-----------

2.25

The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25.

What is subtraction?

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

As per the given,

15 - 12.75

⇒ (14 + 1) - (12 + 0.75)

Open bracket

14 + 1 - 12 - 0.75

14 - 12 + 1 - 0.75

2 + 0.25 = 2.25

Hence "The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25".

Answer:

[tex]7\frac{1}{3}[/tex]

Step-by-step explanation:

So for this problem, we want to solve for x

75x + 50 = 600

First, we isolate x by subtracting 50 from both sides.

75x + 50 - 50 = 600 - 50

75x = 550

Then we divide both sides by 75 to find x

75*x/75=550/75

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr^3

A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...

  V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3

Rounded to tenths, that's approximately 4188.8 yd^3.
