Step-by-step explanation:

We have the following inequality 3 (x + 2)> x

To solve the inequality, apply the following steps:

1) Apply distributive property

[tex]3 * x + 3 * 2> x\\\\3x + 6> x[/tex]

2) Subtract 6 on both sides of the inequality

[tex]3x +6 -6> x-6\\\\3x> x-6[/tex]

3) Subtract x on both sides of the inequality

[tex]3x-x> x-x-6\\\\2x> -6[/tex]

3) Divide by 2 both sides of the inequality

[tex]x> -3[/tex]

The solution is all numbers greater than -3

ANSWER

{x|x>- 3}

EXPLANATION

The given inequality is;

[tex]3(x+2) \: > \: x[/tex]

Expand the parenthesis to obtain,

[tex]3x+6>x[/tex]

Group like terms

[tex]3x-x \: > \: -6[/tex]

[tex]2x>-6[/tex]

Divide both sides by 2

[tex]x \: > \: - 3[/tex]

The correct choice is D.

Multiply the side length by the number of sides to get the perimeter. The formula for finding the perimeter of a regular polygon is just the number of sides x the length of any side. Once you've multiplied those 2 numbers together, you've found the perimeter of the polygon

Final answer:

The perimeter of a polygon is calculated by adding together the lengths of all its sides. For regular polygons with equal side lengths, the perimeter is the side length multiplied by the number of sides. For irregular polygons, all unique side lengths must be measured and summed.

Explanation:

The perimeter of a polygon is the total length around the shape. It is calculated by summing the lengths of all its sides. For a regular polygon with all sides of equal length, like a square, if one side length is a, then the perimeter is simply 4a because there are four sides. In the case of irregular polygons, each individual side length must be measured and added together to find the total perimeter.

For instance, consider a rectangle with a length of l and a width of w; the perimeter would be 2l + 2w, because each opposite pair of sides are equal. The units used for the lengths will be the same units used for the perimeter, such as meters. Nonetheless, the calculation can become more complex with polygons of more sides. Each side must be accounted for precisely, and units must remain consistent.

Answer with step-by-step explanation:

We are given the following two functions:

[tex]s(x) = 3x - 6[/tex]

[tex]t(x) = 6 - 3x[/tex]

We are to find the simplified formula and domain for [tex] v ( x ) = \frac { s ( x ) } { t ( x ) } [/tex] and [tex] w ( x ) = \frac { t ( x ) } { s ( x ) } [/tex].

[tex]\frac{3x-6}{6-3x}=\frac{3(x-2)}{3(2-x)}=\frac{x-2}{2-x}=\frac{x-2}{-(x-2))}=-1 [/tex]

So the domain for this function is (-∞, +∞) for v(x) = -1.

[tex]\frac{6-3x}{3x-6}=\frac{3(2-x)}{3(x-2)}=\frac{2-x}{x-2}=\frac{2-x}{-(-x+2)}=\frac{2-x}{-(2-x)}=-1[/tex]

The domain of this function is (-∞, +∞) for w(x)= -1

ANSWER

v(x)=-1

Domain: (-∞,2)U(2,+∞)

EXPLANATION

We have the given function

s(x) = 3x - 6 and t(x) = 6 - 3x.

We want to find the simplified formula and domain for

[tex]v(x) =( \frac{s}{t} )(x)[/tex]

[tex]v(x) = \frac{s(x)}{t(x)} [/tex]

[tex]v(x) = \frac{3x - 6}{6 - 3x} [/tex]

This function is defined if and only if

[tex]6 - 3x \ne0[/tex]

[tex]x \ne2[/tex]

Hence the domain is:

[tex]x \ne2[/tex]

We now simplify to obtain;

[tex]v(x) = \frac{ - (6 - 3x )}{6 - 3x} = - 1[/tex]

Option B is correct.

In solving the inequality, 3x+8/x-4 <= 0, we identify critical points and assign intervals based on them. The solution offers two possible scenarios: x is less than or equal to -8/3 or x is greater than 4.

The inequality 3x+8/x-4 =< 0 can be divided into two possible scenarios by clarifying the critical points. To solve this inequality, you first need to identify where the expression equals zero, that's where 3x+8=0 and x=4. Solving 3x+8=0 yields x=-8/3, which is the first

possible solution. Another critical point is where the denominator is zero, which is x=4.

Next, we need to check the signs of these intervals: (-inf, -8/3), (-8/3, 4) and (4, inf). Testing these intervals on the given inequality gives us the

solution that x is less than or equal to -8/3 or x is greater than 4 . Remember, x cannot be equal to 4 because it makes denominator zero in the origin expression which is undefined in mathematics.

Therefore, the correct solution is 'x less than or equal to -8/3 or x greater than 4'.

36 x (100/12) = 300

The total number of candy bars was 300

Jillian sold 12% of the class's candy bars, which amounts to 36 bars. To find the total, calculate what 1% would be by dividing 36 by 12, and then multiply by 100 to find that the class sold 300 candy bars in total.

The student is asking about a practical application of percentages in a real-world context, which is a common subject in middle school mathematics. To find the total number of candy bars sold by the class, we need to use the information that Jillian sold 12% of the total and that this amounted to 36 candy bars. The calculation is straightforward: if 12% equals 36, we want to find 100% (the total).

To do this, we set up a simple proportion: if 12% is 36, then 1% would be 36 divided by 12, which is 3 candy bars. Since we're looking for the total, we multiply the number of candy bars representing 1% (which is 3) by 100 to find that the class sold a total of 300 candy bars before taxes.

Step-by-Step Calculation:

Find 1% of the total by dividing 36 candy bars by 12%.

1% of the total = 36 candy bars / 12 = 3 candy bars.

Multiply the value of 1% by 100 to find the total amount.

Total candy bars = 3 candy bars × 100 = 300 candy bars.

Answer:

Final answer is $12696.

Step-by-step explanation:

Given that initial amount P = $28000

Interest rate r = 5.8% = 0.058

Time = 1 year

Then future value is given by :

[tex]A=P\left(1+r\right)^t[/tex]

[tex]A=28000\left(1+0.058\right)^1=29624[/tex]

Similarly calculate future value for 2nd case:

Given that initial amount P = $16000

Interest rate r = 5.8% = 0.058

Time = 1 year

Then future value is given by :

[tex]A=P\left(1+\frac{r}{n}\right)^{n\left(t\right)}[/tex]

[tex]A=16000\left(1+0.058\right)^1=16928[/tex]

then difference = 29624 - 16928 = 12696

Hence final answer is $12696.

Answer:

$696.

Step-by-step explanation:

We are asked to find the amount of interest earned on $28,000 than $16,000 with APYs of 5.8% for a year.

We will use simple interest formula to solve our given problem.

[tex]I=Prt[/tex]

[tex]I[/tex] = Amount of interest,

P = Principal amount,

r = Interest rate in decimal form,

t = Time in years.

[tex]5.8\%=\frac{5.8}{100}=0.058[/tex]

Let us find difference of interests as:

[tex]\$28,000\times 0.058-\$16,000\times 0.058[/tex]

[tex](\$28,000-\$16,000)\times 0.058[/tex]

[tex](\$12,000)\times 0.058[/tex]

[tex]\$696[/tex]

Therefore, it will earn $696 more in interest.

In this situation of selling two properties for the same price but with different gain and loss percentages, the real estate agent does not break even but incurs an overall loss of 6.25%.

This is essentially a problem in profit and loss calculations in the domain of Mathematics. Since the selling price of both the sites is the same, the loss and gain percent will cancel out each other, resulting in no overall gain or loss. Here's why:

The total cost price is Rs. 14400 + Rs. 24000 = Rs. 38400 and the total selling price is Rs. 18000 + Rs. 18000 = Rs. 36000. So, the real estate agent has incurred an overall loss. To find the percentage of loss, use the formula face: [(Loss) / (Cost Price)] * 100 = [(Rs. 38400 - Rs. 36000) / Rs. 38400] * 100 = 6.25% loss.

The x-coordinates of points P and Q, where lines y=2x+8 and y=2x-12 intersect the x-axis, are -4 and 6 respectively. Therefore, the distance between them, PQ, is 10 units.

The two given lines are y = 2x + 8 and y = 2x - 12. These lines intersect the x-axis when y = 0. Setting y=0 in these two equations, we find the x co-ordinates of the intersection points P and Q.

For y = 2x + 8, solving 2x + 8 = 0 gives x = -4. Hence, Point P is at (-4,0).

Similarly, for y = 2x - 12, solving 2x - 12 = 0 gives x = 6. Hence, Point Q is at (6,0).

The distance PQ can then be calculated using the distance formula: "PQ = |Q - P| = |6 - (-4)| = 10 units".

Answer:

22 feet²

Step-by-step explanation:

We are given:

height of tree h = 45 inches

Circumference= πd × inches

But d = 22.2inches

Therefore area will be

Area = 22.2π × 45 inches²

Area = 3137 inches²

Let's convert from inches² to feet², we have:

1 foot = 12 inches.

Therefore,

1 square foot = 1foot × 1foot = 12inches×12inches

= 3137inches² / 144 inches²

= 22feet²

Note: I attached missing data which states that diameter at year 13 is 22.2inches

To calculate the square footage of the tree wrap needed, we multiply the circumference of the tree trunk by the desired height. Assuming the tree trunk is cylindrical, we use the formula for the circumference of a circle: C = 2πr. Then, we convert the height to feet and calculate the square footage.

To calculate the square footage of the tree wrap needed, we need to find the circumference of the tree trunk and multiply it by the desired height. Assuming the tree trunk is cylindrical, we can use the formula for the circumference of a circle: C = 2πr. We can then multiply the circumference by the desired height to get the square footage. Since we know the height is 45 inches, we need to convert it to feet by dividing by 12. Let's say the circumference of the tree trunk is 10 feet. The square footage of the tree wrap needed would be C * H = (2πr) * H = (2π * 5) * 3.75 = 47.12 square feet (rounded to the nearest square foot).
