How do we write algebraic expressions? ( You can explain which keywords tells you to add, subtract, multiply and divide) Give two examples.

Answers

Answer 1

Answer:

Step-by-step explanation:Before you can tackle complex word problems, you need to know how to translate simple problems into algebra. Generally, you'll do this by replacing the words with operators that mean the same thing. So for instance, four divided by x could be 4 ÷ x. ÷ and / are just two ways of writing divided.      If you were to translate this word for word, you'd change the word times to a multiplication symbol (⋅) and put a plus sign (+) between the four and the two. Your expression would look like this:

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data

4 x (58 x 25) = 4 x (25 x __) = (__ x __) x 58 = ____

(293 x 50) x 20 = 293 x (50 x __) = ___

Answers

Answer below:

4 x (58 x 25) = 4 x (25 x 58) = (25 x 4) x 58 = 5800

(293 x 50) x 20 = 293 x (50 x 20) = 293000

The required solutions would be below which are commutative Properties of Multiplication illustrated here:

4 × (58 × 25) = 4 × (25 × 58) = (25 × 4) × 58 = 5800

(293 × 50) × 20 = 293 × (50 × 20) = 293000

What is the Commutative Property of Multiplication?

The commutative property of multiplication says that the result is unchanged by how we multiply the two integers.

If 3 and 7 are the numbers, then 3 × 7 = 21, and 7 × 3 is also equal to 21. Thus 3 × 7 = 7 × 3. Therefore, the commutative property holds true for the multiplication of numbers.

According Commutative Property of Multiplication,

4 × (58 × 25) = 4 × (25 × 58) = (25 × 4) × 58 = 5800

(293 × 50) × 20 = 293 × (50 × 20) = 293000

Hence, the numbers are commutative Property of Multiplication is illustrated here.

identify the slope and y-intercept of the function y = -2x+4

Answers

The y intercept is 0 because when you find x it’s 2 so you plug that in and you get y=0

Answer:

Slope = -2

y-intercept = (0, 4)

Step-by-step explanation:

The equation is written in slope-intercept form, y = mx + b, where "m = slope" and "b = y-intercept". Thus, we have to identify what part of the equation is part of each element in slope-intercept form:

Slope-intercept form

y = mx + b

Equation:

y = -2x + 4

m = -2

b = 4

Thus, the slope is -2 and the y-intercept is (0, 4)

He considers the smallest ratio of blue marbles: 58/200
He considers the largest ratio of blue marbles: 82/200
He estimates that there are most likely between 580 and 820 blue marbles in the jar.

Is Omar's estimate reasonable? Why or why not?

It is not because only doing the first one you need to scale it to 1000 so you would need to multiply 58 by 5 and that only gets you to 290 so automatically the estimate can not be reasonable.

How many quadrants plane have a positive x-value?

Answers

Answer:

2

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

Each side has angle 24°

So,

n = 15 sides

I hope my answer helps you.

Answer:
The polygon has 5 sides.

Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.

=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

The volume of a cone is 80π cubic units. The radius of this cone is tripled.

Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.

Answers

Natalie is correct. The volume of a cone is given by the formula:

V = (1/3)πr^2h

Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.

To see this more clearly, consider the following example:

Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:

V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units

If we triple the radius of the cone to 6 units, the volume of the cone becomes:

V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units

The volume of the cone has been multiplied by 9.

D

Step-by-step explanation:

Using the rules of exponents

\(a^{m}\) × \(a^{n}\) = \(a^{(m+n)}\) and \(a^{-m}\) = \(\frac{1}{a^{m} }\)

Given

\(2^{-4}\) × 2² = \(2^{(-4+2)}\) = \(2^{-2}\) = c , hence

c = \(2^{-2}\) = \(\frac{1}{2^{2} }\) = \(\frac{1}{4}\) → D

Answer:

The answer is option D.

Step-by-step explanation:

2^-4 • 2² = a^b = c

Use the rules of indices

Since the bases are the same and they are multiplying we add the exponents

That's

2^-4 + 2 = a^b = c

2^-2 = a^b = c

a^b = 2^-2

c = 1/4
