Answer:

The length of the car affects how fast it travels down the ramp

Step-by-step explanation:

It does not tell us the length

The length of the car affects how fast it travels down the ramp cannot be concluded by the given table.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The mass of the car affects how fast it travels down the ramp can be concluded from the table given.

The car with more mass will travel the fastest down the ramp can be concluded from table or data given.

The length of the car affects how fast it travels down the ramp can not be concluded by the given data as there is no length given in the table.

The car with the least mass will travel slowest down the ramp also be concluded from the data.

Hence, the length of the car affects how fast it travels down the ramp cannot be concluded by the given table.

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

How to solve:

    Let's follow his process step-by-step to analyze what property is being used. The breakdown is as follows:

Jayden's work

Set up equation                                                     9(2 + 7x)

Step 1                                                                      9(7x + 2)

Step 2                                                                     9(7x) + 9(2)

Step 3                                                                      (9*7)x + 18

Breakdown

Set up equation                                                     9(2 + 7x)

Step 1: Commutative Property of Addition

This property states that when adding, the order of the numbers being added does not matter, and are therefore interchangeable.

Original equation: 9(2 + 7x)

Equation's formula: a(b + c)

Changed equation: 9(7x + 2)

Equation's formula: a(c + b)

By swapping the b and c values in the parentheses, Jayden is demonstrating the Commutative Property. Both will still produce the same sum.

Step 2: Distributive Property of Multiplication

This property states that the sum of two addends that are multiplied by the same number is equal to the product of that number multiplying the sum of both addends.

Original equation: 9(7x + 2)

Equation's formula: a(c + b)

Changed equation: 9(7x) + 9(2)

Equation's formula: a(c) + a(b)

By splitting the parentheses and multiplying each term separately, Jayden is demonstrating the Distributive Property. Both will produce the same product.

Step 3: Associative Property of Multiplication

This property states that the product of three terms, where one is outside of the parentheses multiplying the other two, is not affected by changing which term is on the outside of the parentheses.

Original equation: 9(7 * x) +18

Equation's formula: a(c*x) + (ab)

Changed equation: x(7*9) + 18

Equation's forumula: x(c*a) +18

By swapping the 9 and x variables, Jayden is demonstrating the Associative Property. Both will produce the same product.

Simplified:

Step 1 - Commutative Property

Step 2 - Distributive Property

Step 3 - Associative Property

Step-by-step explanation:

The surface area of the square pyramid is 1040 ft² in the given figure.

The total surface area of the given pyramid can be expressed as:

Surface area of a square pyramid = A + (1/2) p × s

where A is the base area, p is the perimeter of the base, and s is the slant height

As per the question, we have

length (l) = 20 ft

base perimeter (p) = 4l = 4 × 20 = 80 ft

base area (A) = l² = 20² = 400 ft²

slant height (s) = 16 ft

Substitute the values in the formula for surface area:

Surface area = 400 + 1/2 × 80 × 16

Surface area = 400 + 1280/2

Surface area = 400 + 640

Surface area = 1040 ft²

Thus, the surface area of the square pyramid is 1040 ft².

Fractions have different applications in the real word. We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie. They can also be interpreted as decimals and percentages.

Step-by-step explanation:

Hope this helps!

All the correct methods to interpret fractions is,

Fractions as parts of wholes or parts of sets;

Fractions as the result of dividing two numbers;

Fractions as the ratio of two quantities;

Fractions as operators; and fractions as measures.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

To find the method for interpret fractions.

Since, Fractions have different applications in the real word.

Hence, We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie.

A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.

B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.

C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.
