Answer:

27.77

Step-by-step explanation:

To convert a decimal to a percentage, multiply by 100 (just move the decimal point 2 places to the right).

0.2777 × 100 = 27.77

The value of k that makes the statement true is: k = -4.

If we are given an equation that has an unknown variable, to find the value of the variable, solve to isolate the variable. The value of the variable is what will make the equation a true statement.

Given the equation:

-k + 12 = 16

Subtract 12 from both sides

-k + 12 - 12 = 16 - 12 [subtraction property]

-k = 4

Divide both sides by -1

-k/-1 = 4/-1 [division property]

k = -4

Check: substitute k = -4 into the equation

-k + 12 = 16

-(-4) + 12 = 16

4 + 12 = 16

16 = 16 [true]

Therefore, the value of k that makes the statement true is: k = -4.

The domain is all real numbers of x that makes the expression defined.

Set-builder notation: { x| x ≥ 0 }.

Interval notation: [0,∞).

Given the function in the question;

f(x) = 3√3x - 3

To determine the domain, we find where the expression is defined by setting the radicand √3x to be greater than or equal to zero and solve for x.

3x ≥ 0

Divide both sides by 3

3x ≥ 0

3x/3 ≥ 0/3

The number of video games that Max will have left when he keeps one is 18 games.

It should be noted that the total amount that he has is $625.95.

Cost of each video game = $32.10

Therefore, the number of games that he can buy will be:

= Amount / Cost of game

= $625.95 / $32.10

= 19.5

= He can buy 19 games.

Therefore, if he keeps one, the number left will be:

= 19 - 1 = 18

He I'll have 18 left.

The graph of the piecewise function is given at the end of the answer. From the graph, and from it's concepts, we have that:

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, the function has two definitions, as follows:

Both are decreasing linear functions, with the definition opening a space at x = 0, between y = 0 and y = -2, as shown in the graph. The closed interval, due to the equal sign, is at x = 0.

Population in the year 2000= 198.85million

From the question, we get to know that the population in 2009 was 191.5 million.

And we have to find the population of the year 2000 which is 3.7%more than the 2009 population.

So let us take the population of the year 2000 to be x.

From the above, we can form an equation:

(population of year 2000 * ( 100-3.7 /100) = (population of year 2009)

i.e., x * 100-3.7/ 100 = 191.5

x * 96.3 = 191.5

x = 198.85

So 198.85 is the population of 2000.

the zeroes of the function f (x) = 2 x² + 8 x - 3 are x = - 2 ± √ 11 / 2.

We are given a function:

f (x) = 2 x² + 8 x - 3

We need to use the completing the square method to find the zeroes.

f (x) = 2 x² + 8 x - 3

f (x) =  x² + 4 x - 3 / 2

f (x) =  ( x )² + 2 (2) (x) + (2)² - (2)² - 3 / 2

f (x) = ( x + 2 )² - 4 - 3 / 2

f (x) = ( x + 2 )² - 11 / 2

(x + 2)² = 11 / 2

x + 2 = ± √ 11 / 2

x = - 2 ± √ 11 / 2

Therefore, the zeroes of the function f (x) = 2 x² + 8 x - 3 are x = - 2 ± √ 11 / 2.

Comparing the values by subtraction, the chocolates are lighter than the weight stated on the label by 0.0042 pounds.

When comparing two values whether which is greater, compare the digits from left to right.

Comparing 0.384 to 0.3798, where the first digits are both 0, and the digit after the decimal are also the same, compare the hundredth's place.

8 > 7

Hence, the actual weight of the chocolates is less than or lighter than the weight stated on the label.

Using subtraction, two values can also be compared by getting how much one exceeds the other.

Subtracting the two values,

0.384 - 0.3798 = 0.0042 pounds

According to the solving the line segment LM of line KM = 3.

A line segment is defined as the area between two different points on a line. A line segment is a section of a line that links two points. A line has no endpoints and stretches in both directions indefinitely, but a line segment includes two fixed or definite endpoints.

In general, if both end points of a line segment are vertices of such a polygon or polyhedron, the line segment has to be either the edge (of that polygon or polyhedron) if they are both adjacent vertices, or a diagonal. A chord is a line segment whose end points are both on a curve (such as a circle) (of that curve).

KL = 9

LM = x - 1

KM = -4 + 4x

So

KL + LM = KM

Substituting the value we get:

9 + x - 1 =  -4 + 4x

8 + x = -4 + 4x

8 + 4 = 4x - x

12 = 3x

x = 4

The value of x  = 4 putting the value in the (LM = x - 1):

We get:

LM = x - 1

LM = 4 - 1

     = 3

LM = 3

It will cost $49.5 for the ten items.

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Total items purchased = 10

Each item cost = $4.95

Thus, Cost of 10 items = 10*Each item cost

Putting the value we get,

Cost of 10 items = 10*4.95

Solving we get,

Cost of 10 items = $49.5

Using a proportional relationship, it is found that:

A direct proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality k, as follows:

y = kx

From point (1.5, 45) on the graph, the constant is given as follows:

k = 45/1.5

k = 30.

Hence the equation is:

y = 30x.

In which:

Hence, point (1.5, 45) means that the 1.5 hours, he traveled 45 miles.

From the constant k = 30, we have that in one hour, Larry traveled 30 miles, also meaning that:

His distance changed at a unit rate of 30 miles per hour, so Larry's speed was of 30 miles per hour.

The slope of the graph is the velocity, hence:

If Larry had driven more slowly, the slope of the graph would be less than 30.
