The correct statement for the rational number is the opposite of the opposite of -12 is -12.

What is rational number?

Rational numbers are those numbers which include natural numbers, whole numbers as well as integers. And it is written in the form of a/b where a and b are integers. Sometimes, the values of the denominator is one then the given number is not fraction.

According to the question, rational number are those numbers which takes positive integers, negative integers as well as zero.

Therefore, on a number line, the opposite of (-12) is 12. And again the opposite of 12 is (-12). Therefore the first statement is correct.

Hence, the correct statement for the rational number is the opposite of the opposite of -12 is -12.

Range:

{5,3,8,−4}

Step-by-step explanation:

The product of the numbers 758 and 93 is 70494

The numbers are given as

758 x 93

By using the standard algorithm i.e. the partial product method, we have the following equation

758 x 93 = 758 x (90 + 3)

Open the bracket

So, we have the following equation

758 x 93 = 758 x 90 + 758 x 3

Evaluate the products

758 x 93 = 68220 + 2274

Next, we evaluate the sum

758 x 93 = 70494

This means that the final product is 70494

Time taken to cover path around the park if he runs at speed 5miles/hour is 15.96min

What is Speed ?

Speed indicates how quickly something or someone is moving. If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance x time.

Given that,

Time taken when Bob runs 4miles/hour = 20min

Time taken when Bob runs 5miles/hour = ?

First we have to find the distance of the path around the circle

Distance = speed x time

               = 4 x 20/60

               = 4/3 miles

               = 1.33 miles

Now to calculate the time when he ran 5 miles/hours:

Time = distance / speed

         = 1.33 / 5

         = 0.266hours

0r

         = 0.266 x 60 min

         = 15.96 min

Hence, its will take 15.96min to cover the path around the park

Recall that:

Therefore:

Simplifying the above result, we get:

If  he increased his average speed to 300 m/min and finish the race on minute faster than he had during training. The distance of the race is:  1500 meters.

Slower speed :

rate = 250 m/min

time = x minutes

distance = r×t = 250x meters

Faster speed :

rate = 300 m/min

time = x - 1 minutes

distance = 300x - 300 meters

Equate

distance  = distance

250x = 300x - 300

Collect like terms

50x = 300

Divide both side by 50x

x = 300/50

x = 6 minutes

Hence,

Race distance = 250x where x =6

Race distance = 250×6

Race distance= 1500 meters

Therefore we can conclude that the distance is 1500 meters.

When he spends $52 in total, the number of bottles of water and protein bars that he buys will be 40 and 20 respectively.

It should be noted that an equation is used to show the relationship between the variables.

In this case, Kawan buys some protein bars at $0.80 each and bottled water at $0.90 each for a group hike and he buys twice as many bottles of water as protein bars.

Let x = the number of protein bars

Table waters = 2x

Therefore, the equation will be:

0.8x + 0.9(2x) = 52

0.8x + 1.8x = 52

2.6x = 52

Divide

x = 52/2.6

x = 20

The number of proteins bars is 20.

The number of water will be:

There are 90 apples in the pile and the row has 4 fewer apples than the row below.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The sum of an arithmetic sequence is the sum of the first n terms of the sequence as

Sₙ = n/2(2a+(n−1)d)

In arithmetic, here a₁ is the first term and sequence d represents the common difference.

Sum of the apples = 25 + 21 + 17 + 14 + 13 + 9

This series is in AP where a = 25 , d = - 4 and n = 6

As per the given data, the sum of apples would be as:

S₆ = 6/2(2×25+(6-1)×-4)

S₆ = 3(50 + 5×-4)

S₆ = 3(50 - 20)

S₆ = 3(30)

S₆ = 90

Answer:24 bags

Step-by-step explanation:

Using the given information, the number of bags created with  random seed packets is 16 complete bags of seeds and a remainder of 5 seed packets

The number of bags created achieved by division. This is a basic mathematical operator used in sharing items

Given information

Seed Type                                 Number of Packets

Aster                                                       95

Daisy                                                       160

Pansy                                                      70

Sunflower                                                 -

Wildflower                                                -

Adding the number of packets available gives

95 + 160 + 70 = 325 seed packets

Sharing them in a bag containing 20 seed packets each we divider the total number of seed packets by 20

= 325 seed packets / 20

= 16.25

Therefore 16 bags will be created and 5 will be remaining

Using the polynomial expression, the non-real solutions are x = (2 + i√26)/3 and  x = (2 - i√26)/3

Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators

The equation of the polynomial expression is given as:

3x^3 + 14x^2 - 14x + 60 = 0

From the question, we have

Real solution = -6

Rewrite the above equation as

x = -6

Add 6 to both sides of the equation

So, we have

x + 6 = 0

The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0

This is represented as

3x^3 + 14x^2 - 14x + 60/x + 6

Using a graphing calculator, we have

3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10

Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3

So, we have

x = (4 ± √-104)/6

This gives

x = (4 ± 2√-26)/6

Divide

x = (2 ± √-26)/3

Rewrite as

x = (2 ± i√26)/3

Split

x = (2 + i√26)/3 and  x = (2 - i√26)/3

Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and  x = (2 - i√26)/3

The solution of the given inequality for the value of x, x ≥ 1/2.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than. Both mathematical phrases, equations, and inequalities are created by connecting two expressions. The equal sign (=) indicates that two expressions in an equation are believed to be equivalent. The symbols >,<,≥,≤,≠ or indicate that the two expressions in inequality are not always equal.

Integer represents the total change in the time when you use 5 clues with the condition of using 3 free clues is equal to 10 minutes.

As given in the question,

Number of free clues =3

Total number of clues used to escape from a room = 5clues

Out of these 5 clues, 3 clues are free to use. Hence these 3 clues do not result in any time change.

Hence total time elapsed after usage of 3 clues = 0

Each removes 5 minutes from your remaining time

Integer represents the total change in the time for the usage of 4th and 5th clue = 10 minutes

So overall change in timeline after consuming 5 clues = 10 minutes since each of the 4th and 5th clue results in decrease of 5 minutes each; thus effecting 10 minutes total time change (reduction)

The cost of the jalapeno poppers is $11.09    .

In the question ,

it is given that

Cost of the nachos = $18.85

amount paid by each friend = $9.98

amount paid by three friends = 9.98*3 = $29.94

let the cost of jalapeno poppers = $x

So according to the question

the total amount paid by three friends = cost of nachos + cost of jalapeno poppers

Substituting the values from above , in the equation we get

29.94 = 18.85 + x

simplifying further , we get

x = 29.94 - 18.85
