The solution of the inequation 18x + 6 [tex]>[/tex] 12x + 18 is x [tex]>[/tex] 2.

An inequation is a mathematical statement that represents an inequality relationship between two expressions. It compares the relative values of the two expressions, indicating whether one is greater than, less than, or not equal to the other.

Solving an inequation involves finding the values of the variables that satisfy the inequality. This can often be done by using algebraic techniques, such as simplifying and rearranging the expressions, isolating the variable, and applying appropriate rules and operations.

To solve the above inequation, let's assume that it is an equation.

Then,

18x + 6 = 12x + 18

18x - 12x = 18 - 6

6x = 12

x = [tex]\frac{12}{6}[/tex]

x = 2.

Thus the inequation in simplifying is x [tex]>[/tex] 2.

Final answer:

The result to the inequality 18x 6> 12x 18 is x> 2. This is set up by abating 12x from both sides, also abating 6, and also dividing by 6 to insulatex.

Explanation:

To break the inequality 18x 6> 12x 18, we need to insulate the variable x on one side.

Abate 12x from both sides 18x- 12x 6> 18.

Simplify the equation 6x 6> 18.

Abate 6 from both sides 6x> 12.

Divide both sides by 6 to break for x x> 2.

The result to the inequality is x lesser than 2. This gives a range of values for x that will satisfy the original inequality. thus, any number lesser than 2 for x makes the inequality true.

Answer:

Option C) 8 cups

Step-by-step explanation:

Let

x----> the number of cups

y ---> the number of plates

we know that

y=2x-4 -----> equation A

60%=60/100=0.60

y=0.60(x+y) ----> equation B

Substitute equation A in equation B and solve for x

2x-4=0.60(x+2x-4)

2x-4=0.6x+1.2x-2.4

2x-4=1.8x-2.4

2x-1.8x=4-2.4

0.2x=1.6

x=1.6/0.2

x= 8 cups

From looking at the question, the answer is C. 8

Answer:

0.5

Step-by-step explanation:

Sort the given data in ascending order:

47, 48, 50, 52, 53, 53, 55, 68

Possible outlier is number 68. Check whether this number is an outlier:

[tex]Q_1=49\\ \\Q_2=52.5 \\ \\Q_3=54[/tex]

The interquartile range is

[tex]Q_3-Q_1=54-49=5[/tex]

Multiply it by 1.5:

[tex]1.5\cdot 5=7.5[/tex]

and add to third quartile:

[tex]7.5+54=61.5[/tex]

Since [tex]68>61.5,[/tex] number 68 is an outlier.

The median of the sample with outlier is [tex]Q_2=\dfrac{52+53}{2}=52.5[/tex]

The median of the sample without outlier is 52

The difference between the median of the data, including the possible outlier and excluding the possible outlier is 52.5-52=0.5

height of prism = [tex]x+1-\frac{4}{x^3+3x^2+8}[/tex]

Step-by-step explanation:

Volume of rectangular prism = (x^4+4x^3+3x^2+8x+4)

Area of its bases = (x^3+ 3x^2+8)

Height of prism = ?

Volume of rectangular Prism = Area of its bases * Height of prism

Answer:

the radius of the circle= 4m

Step-by-step explanation:

Given:

Area of circle=16π m2

radius,r of circle=?

Formula of area of circle is given as

Area=πr^2

Putting values we get

16π=πr^2

r^2=16

r=4

the radius of the circle= 4m !

Given the area [tex]A=\pi r^2=16\pi[/tex] we can solve the formula for radius.

[tex]A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}[/tex]

So,

[tex]r=\sqrt{\dfrac{16\cdot\not{\pi}}{\not{\pi}}}=\sqrt{16}=4[/tex]

The radius is 4m.

Final answer:

To find f(10) using a recursive formula, we can calculate intermediate values starting from f(1) and applying the given rule to find f(10) as 2.

Explanation:

The function is defined as follows:

f(1)=-1.5

f(n+1)=f(n)+0.5

To find f(10), we can use the given recursive formula to calculate subsequent values:

f(2) = f(1) + 0.5 = -1.5 + 0.5 = -1

f(3) = f(2) + 0.5 = -1 + 0.5 = -0.5

Continuing this pattern, we find f(10) = 2

C.  m < A = 152.5 degrees.

Step-by-step explanation:

Use the Cosine Rule:

a^2 = b^2 + c^2 - 2.b.c.cos A

34^2 = 18^2 + 17^2 - 2.18.17 cos A

2.18.17 cos A = 18^2 + 17^2 - 34^2

cos A =  (18^2 + 17^2 - 34^2) / (2.18.17)

cos A = -0.88725

m < A = 152.5 degrees.

I got it correct on founders edtell

Answer:

Step-by-step explanation:

This is a question that uses the Pythagorean Theorem.

a = 35 feet

b = x            which is the height of the tree.

c = 3*x + 1   so we are trying to find x.  Substitute into a b and c

a^2 + b^2 = c^2

35^2 + x^2 = (3x + 1)^2        

35^2 + x^2 = 9x^2 + 6x + 1     Subtract x^2 from both sides.

35^2 = 8x^2 + 6x + 1               Subtract 35^2 from both sides.

0 = 8x^2 + 6x + 1 - 35^2

0 = 8x^2 + 6x - 1224

Does this factor?

(x + 12.75)(x - 12)

x - 12 = 0 is the only value that works.

x = 12

The tree is 12 feet high.

Note: I used the quadratic formula to solve this.

Answer:

12 ft

Step-by-step explanation:

Let the height of the tree is h.

So the distance of top of the tree = 3 h + 1

Distance of base of tree = 35 ft

So, by use of Pythagoras theorem

[tex]\left ( 3h+1 \right )^{2}=h^{2}+35^{2}[/tex]

[tex]8h^{2}+6h-1224=0[/tex]

[tex]4h^{2}+3h-612=0[/tex]

[tex]h=\frac{-3\pm \sqrt{9+4\times 4\times 612}}{8}[/tex]

[tex]h=\frac{-3\pm 99}{8}[/tex]

Take positive sign

h = 12 ft

Thus, the height of tree is 12 ft.

Answer:

[tex](g \circ f)(x)=10x^2-60[/tex]

Answer:[tex]10x^2-60[/tex]

Step-by-step explanation:

[tex](g \circ f)(x)=g(f(x))[/tex]

Replace [tex]f(x)[/tex] with [tex]x^2-6[/tex].

This gives us:

[tex](g \circ f)(x)=g(f(x))[/tex]

[tex](g \circ f)(x)=g(x^2-6)[/tex]

This means to replace the old input variable with new input, [tex](x^2-6)[/tex].

Let's do that:

[tex](g \circ f)(x)=10(x^2-6)[/tex]

They probably want you to distribute:

[tex](g \circ f)(x)=10x^2-60[/tex]

Answer:

10x^2-60

Step-by-step explanation:

(G o F)(x) is the same as g(f(x)). We know that f(x)=x^2-6. So now you have to find g(x^2-6). To solve for that plug in x^2-6 in for x in the original equation for g(x). You get 10(x^2-6) or 10x^2-60

Answer:

60(1/5)^(n-1).

Step-by-step explanation:

The common ratio  r   is 12/60 = 12/5 / 12  = 12/25 / 12/5 = 1/5.

The first term a1 = 60 so the explicit rule is

a1 * r^(n-1)

= 60(1/5)^(n-1).

aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .This can be obtained by using the formula of geometric sequence.

Sequence is s collection of objects in a particular order and repetitions are allowed.

Geometric Sequence:

In the given question, first term a=60

Common ratio r = a₂/a₁ = 12/60 = 1/5 ⇒ r = 1/5

By definition, arⁿ⁻¹ = (60)(1/5)ⁿ⁻¹ is the required explicit rule for the geometric sequence.

Hence aₙ=60(1/5)ⁿ⁻¹ is the explicit rule for the geometric sequence 60,12,12/5, 12/25,12/125,... .

Y=-4x-5

Step-by-step explanation:

-21=-4(4)+b

-21=-16+b

b=-5

y=-4x-5

Answer:

y = - 4x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 5 is in this form with slope m = - 4

• Parallel lines have equal slopes, hence

y = - 4x + c ← is the partial equation of the parallel line

To find c substitute (4, - 21) into the partial equation

- 21 = - 16 + c ⇒ c = - 21 + 16 = - 5

y = - 4x - 5 ← equation of parallel line

The given frequency is showing only 4 intervals, that means there should be only 4 bars in the right histogram, that lead us only to the first or second choice as right answers.

Now, according to the frequency table the first interval is larger than the second interval and the third interval is larger than the fourth interval. This means the first bar must be taller than the second bar, and the third bar must be taller than the fourth bar, and the second histogram is showing this.

Therefore, the right histogram is the second one.

Answer:

They can buy 160 commercial vans, 80 small trucks and 40 large trucks.

Step-by-step explanation:

The company plans to spend $8 million on 280 new vehicles.

Commercial van = $25,000

Small truck = $30,000

Large Truck = $40,000

Let 'x' be commercial van, 'y' small truck and 'z' large truck. Therefore:

x + y + z = 280

Also, we know that x = 2y

Therefore: 3y + z = 280

Also we know that:

25,000x + 30,000y + 40,000z = 8,000,000

50,000y + 30,000y + 40,000z = 8,000,000

80,000y + 40,000z = 8,000,000

Therefore, we need to solve the following system of equation:

3y + z = 280  [1]

80,000y + 40,000z = 8,000,000  [2]

We have that the results are: y=80, z=40 and x=160.

Therefore, they can buy 160 commercial vans, 80 small trucks and 40 large trucks.

Answer:

Step-by-step explanation:

Hey diddle diddle the medians in the middle you add then divide for the mean. the mode is the one that appears the most and the range is the difference in between.

Median: you have to organize the numbers from least to greatest then eliminate one by one.

12, 15, 15, 18, 20, 29, 33, 42

eliminate 12, and 42

15, 15, 18, 20, 29, 33

eliminate 15, and 33 ... so on

once you get to the median you end up with two numbers.

18, 20

because you can only have one median you find the number between, which in this case would be 19

Answer:

19

Step-by-step explanation:

The median is the middle value of the data in ascending order. If there is no exact middle then it is the average of the two values either side of the middle.

Arrange in ascending order

12, 15, 15, 18, 20, 29, 33, 42

The middle is between 18 and 20

median = [tex]\frac{18+20}{2}[/tex] = [tex]\frac{38}{2}[/tex] = 19

Answer:

The correct option is A) Q and W are similar but not congruent.

Step-by-step explanation:

Consider the provided graph.

Figure Q is a quadrilateral with sides measuring 5 and 2

Figure S is a quadrilateral with sides measuring 5 and 2.

Figure W is a quadrilateral with sides measuring 10 and 4.

Two figures are similar if the shape of the figures are same but not necessarily same size.

Two figures are congruent if the size and shape of the figure are same.

Note: If two figures are congruent, then they are also similar, but converse is not true.

The dimensions of Q is equals to the corresponding dimensions of the rectangle S. Thus, Q and S are similar and congruent as they have the same shape and the same size.

The dimension of quadrilateral W is 2 times of quadrilateral Q and S. Thus the dimensions of W is proportional to dimensions of Q.

That means quadrilateral W is similar to Q and S but not congruent.

Thus, the correct option is A) Q and W are similar but not congruent.
