Tips to Add Negative and Positive Numbers:

1.) Adding a negative number to a positive number is subtracting it.

example: 5 + (-3) = 5 - 3

2.) Adding a positive number to a smaller negative number is subtracting the smaller number by the larger one.

example: -3 + 5 = 5 - 3

3.) Adding a positive number to a larger negative number is having the positive number subtracted by the larger negative.

example: -5 + 3 = 3 - 5  (but the final answer needs a negative sign)

4.) Adding a negative number to another negative number is adding the numbers together, but with a negative sign in the final calculation.

example: -3 + (-2) = 3 + 2  (but the final answer needs a negative sign)

5.) I think you know how to add two positive numbers

The surface area of the square pyramid with length of the base 6m and slant height of the pyramid 5m is 96 m².

A square pyramid is a 3-D geometrical figure with the base of the shape of square and four triangular faces from each side of the square joining together at the top to form vertex.

The surface area of a square pyramid is given as:

Base area of the square face + 1/2 (perimeter of base × slant height)

Since square base has side of length 6m and the slant height of the pyramid is 5m then surface area is given by;

Surface area = (6×6) + 1/2 (4×6×5)

=> 36 + 1/2 (120)

=> 36 + 60

=> 96 m²

Thus, surface area of square pyramid is 96 m².

The area of the triangle is 6√3 square units.

A triangle with a right angle or two perpendicular sides is referred to as a right triangle, a right-angled triangle, or perhaps more formally as an orthogonal triangle (formerly known as a rectangle triangle). Trigonometry's foundation is the relationship between the right triangle's sides and other angles.

The ratios of a given object's sides 30°-60°-90° triangle are 1 : √3: 2.This information allows us to calculate the lengths of something like the triangle's orthogonal sides.

61/100 is the equivalent fraction for the given decimal number.

A decimal number then has two components: a whole number part and a fractional part. The decimal place value system for the whole part of a decimal number is the same as the whole number value system. However, we get the fractional part of the decimal number as we move toward the right after the decimal point.

A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken.  The number below the line is called the denominator.  It shows the total number of equal parts the whole is divided into or the total number of the same objects in a collection.

for converting a decimal into a fraction we need to multiply and divide the decimal by the 10^n where n is the number of digits after the decimal.

The line segment BC has a length of 13 units.

In this question we know the locations of the two ends of a line segment. The procedure consists in calculating the vector behind the line segment and later determing its magnitude by Pythagorean theorem. If we know that B(x, y) = (8, - 7) and C(x, y) = (- 4, - 2), then the length of the line segment BC is:

BC = (- 4, - 2) - (8, - 7)

BC = (- 12, 5)

BC = √[(- 12)² + 5²]

BC = 13

Step-by-step explanation:

The x-coordinates form the domain.

We know the x-coordinates of the end points of the line, the first numbers in pair of coordinates:

Also, since both points are closed circles, the endpoints are included.

So the domain is the interval between 0 and 4, both inclusive.

This is shown as:

The matching answer choice is A.

The domain of the function includes all x-values from 0 to 4, including both 0 and 4.

So, the correct answer is option A: {[tex]{x | 0 \leq x \leq 4}\\[/tex]}.

The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. In this case, the function begins with a closed circle at (0, 2) and ends with a closed circle at (4, 6), which means that the function is defined at these specific points.

Since the function is a linear function, it represents a straight line.

A linear function is continuous, and it extends indefinitely in both directions.

Therefore, any x-value between 0 and 4 will also be defined by the linear function.

In mathematical notation, we can represent the domain as:

Domain: {x | 0 ≤ x ≤ 4}

This means that the domain of the function includes all x-values from 0 to 4, including both 0 and 4.

So, the correct answer is option A: {[tex]{x | 0 \leq x \leq 4}\\[/tex]}.

Given that 1 kilometer = 0.62 mile, 36 inches = 1 yard, and 1 mile = 1760 yards, 1 km has approximately 39,283.2 inches.

In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.

A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.

From the problem, the conversion factors are given as

1 kilometer = 0.62 mile

36 inches = 1 yard

1 mile = 1760 yards

To convert 1 kilometer into inches, first, convert 1 kilometer to miles using the conversion factor, 1 kilometer = 0.62 mile

1 km = 0.62 miles

Then, convert miles to yards using the conversion factor, 1 mile = 1760 yards

1 km = 0.62 miles = 0.62 (1760 yards)

1 km = 0.62 miles = 1091.2 yards

Lastly, convert yards to inches using the conversion factor, 36 inches = 1 yard

1 km = 0.62 miles = 1091.2 yards = 1091.2 (36 inches)

1 km = 0.62 miles = 1091.2 yards = 39,283.2 inches

The equation which can be used to solve the the average number of miles he would have to ride to meet his target is 28.7 = 17 + 3x.

The solve equation is x = 3.9 miles.

He wants to ride his bicycle 28.7 miles this week.

He has already ridden 17 miles.

He rides for 3 more days.

The equation which can be used to determine the average number of miles he would have to ride to meet his target can be calculated as follows:

The total distance to ride is 28.7 miles.

Therefore,

28.7 = 17 + 3x

where

Therefore,

28.7 = 17 + 3x

subtract 17 from both sides of the equation

28.7 = 17 + 3x

28.7 - 17 = 17 - 17 + 3x

11.7 = 3x

divide both sides by 3

3x / 3 = 11.7 / 3

x = 11.7  /3

x = 3.9

Therefore, he needs to travels 3.9 miles daily for 3 days.

Answer:

z = -4

Step-by-step explanation:

Let's solve the problem,

→ 3(z - 1) - 1/2 (4z + 10) = 4 (z - 3/2) + 10

→ 3z - 3 - 2z - 5 = 4z - 6 + 10

→ z - 8 = 4z + 4

→ 4z - z = -4 - 8

→ 3z = -12

→ z = -12/3

→ [ z = -4 ]

Hence, the value of z is -4.

Based on the calculations, the sum of the areas of the rectangles is equal to: A. 0.25 square unit.

Mathematically, the area of a rectangle can be calculated by using this formula;

A = LW

Where:

By critically observing the figure (see attachment), we can logically deduce the following information:

Width of rectangle A = 2 units

Width of rectangle B = 2 units.

Width of rectangle C = 4 units.

Next, we would determine the length and area of each of the rectangle.

The length of the first rectangle is given by:

Length of rectangle, y = 3^-x

Length of rectangle, y(0) = 3⁻⁰ = 1 units.

Length of rectangle, y = 3^-x

Length of rectangle, y(2) = 3⁻² = 0.11 unit.

Area of first rectangle = 2(0.11)

Area of first rectangle = 0.22 square unit.

For the second rectangle, we have:

Length of second rectangle, y = 3^-x

Length of second rectangle, y(4) = 3⁻⁴ = 0.012 unit.

Area of second rectangle = 2(0.012)

Area of second rectangle = 0.025 square unit.

For the third rectangle, we have:

Length of third rectangle, y = 3^-x

Length of third rectangle, y(8) = 3⁻⁸ = 0.00015 unit.

Area of third rectangle = 4(0.00015)

Area of third rectangle = 0.0006 square unit.

Now, we can calculate the sum of the areas of the rectangles:

Total area = 0.22 square unit + 0.025 square unit + 0.0006 square unit.

Total area = 0.246 ≈ 0.25 square unit.

Total area of rectangle = 0.25 square unit.
