Step-by-step explanation:

Hello There!

A is not true because overall 22% had trucks of the 100 people while only 9% overall had a van. So more people overall had trucks then vans meaning that vans has the lowest percentage of type of vehicle driven therefore we can eliminate answer choice A

B is also incorrect because from ages 41-50, a total of 14 people drive a van or sedan. Also from ages 41-50, a total of 14 people drive a SUV or truck. Because the total of people that drive each of the grouped vehicles is the same neither of the percentages would be lower or higher therefore we eliminate answer choice B

C is also incorrect because the same amount of people in the age group 31-40 drive trucks as the amount of people in the age group 41-50. Because the same amount of people from the different age groups drive trucks the percentage would be neither higher nor lower therefore C is incorrect

D is the correct answer choice because the total amount of people that drive trucks from the age range 21-30 is the same as the amount of people that drive a truck from other age groups. Or to be more specific the sum of the people who drive a truck from ages 31-40, 41-50 and over 50 is 11 (3+4+4=11) This meaning that the same percentage of people in the age range from 21-30 that drive a truck is the same as the percentage of people that drive a truck from the sum of the other age ranges. Hence the correct answer choice is D

The length of the diameter of the circle which  the equation x + y + 18x-22y = -153 is 3.5 units long.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here (h,k) is the center of the circle and (r) is the radius of the circle.

The equation of the circle given as,

[tex]x^2 + y^2 + 18x-22y = -153[/tex]

Rearrange the equation to make it as standard form,

[tex]x^2 + y^2 + 18x-22y = -153\\x^2 + 18x+ y^2-22y = -153[/tex]

Add 121 and 81 both side of the equation,

[tex]x^2 + 18x+81+ y^2-22y+121 = -153+81+121\\x^2 + 18x+9^2+ y^2-22y+11^2 =41[/tex]

Using the formula of whole square,

[tex](x+9)^2+(x-11)^2=7^2\\(x-(-9))^2+(x-11)^2=7^2[/tex]

Compare it with standard equation, we get the radius of the circle r is 7.

As the radius is half of the diameter. Thus, the diameter of the circle is,

[tex]d=\dfrac{7}{2}\\d=3.5\rm\; units[/tex]

Thus, the length of the diameter of the circle which  the equation x + y + 18x-22y = -153 is 3.5 units long.

If a number in parenthesis is directly next to a number without, then the two numbers need multiplied.

-12(5/6)(-2/15) is an example of a double multiplication. But we'll multiply -12 and 5/6 first, then multiply the product by -2/15.

-12x5/6=14 2/5

Answer:

x = 10

Step-by-step explanation:

By looking at the picture, I can tell the angle of the 3x is also 30 degrees.

This means 3x = 30.

When you solve for x by dividing each side by 3, you result with the answer of x = 10.

To check you work, plug in 10 for x to recieve 30 degrees again.

The possible error of measurement is half of the smallest unit on the tape measure, which is half an inch, option B is correct.

Two or more expressions with an Equal sign is called as Equation.

The possible error of measurement refers to the smallest unit of measurement on the tape measure.

In this case, the tape measure is marked every half inch, so the smallest unit of measurement is 0.5 inches.

Therefore, the possible error of measurement is also 0.5 inches.

This means that any measurement taken using this tape measure may be off by up to 0.5 inches due to the limitations of the instrument used.

Hence, the possible error of measurement is half of the smallest unit on the tape measure, which is half an inch. Therefore, the answer is B. 0.5 in.

Yes, the lines are parallel.

Parallel lines are coplanar straight lines that do not intersect at any point.

We have,

Line [tex]c[/tex] and [tex]d[/tex], and transversal [tex]e[/tex].

[tex]\angle 2 =\angle 3=\angle6=40^0[/tex],

And, [tex]\angle 1=140^0[/tex]

Now,

[tex]\angle 1=\angle4=140^0[/tex]     (Vertically Opposite Angles)

So,

When a transversal line cuts two lines and sum of angles on the same side of the line is [tex]180^0[/tex] .

i.e. [tex]\angle6+\angle4=180^0[/tex]

[tex]140^0+40^0=180^0[/tex]

[tex]180^0=180^0[/tex]

So, sum of [tex]\angle6\ and\ \angle4[/tex] is [tex]180^0[/tex], that means line are parallel.

Hence, we can say that Yes, the lines are parallel.

Answer: $40

Step-by-step explanation:

The tax rate is 6% on the price of the good bought.

This means that $2.40 is 6% of the price of the helmet before taxes.

Assuming the before tax price is x, the price of the helmet is:

2.40 = x * 6%

x = 2.40 / 6%

x = $40

$40 is the before tax cost.

6 times what equals 84?

6 times what equals 84? In other words, what do you multiply by 6 to get 84? If "x" is "what" in the sentence, "6 times what equals 84?", then the equation to solve the problem is as follows:

6 • x = 84

Which can be written as:

6x = 84

To solve the equation above, we need to remove the 6 on the left side to make the x alone. To do that, we divide both sides by 6.

6x/6 = 84/6

6x/6 is x and 84/6 is 14 which means our equation will look like this:

x = 14

Thus, the answer to "6 times what equals 84?" is 14.

Answer:

14

Step-by-step explanation:

cause 84 divided by 6 is 14,then do 14 times 6 and its 84.

Answer:

The time it would take the element to decay to 28 grams is approximately 22.5 minutes

Step-by-step explanation:

The give half life of element X = 6 minutes

The given initial mass of the radioactive element X = 390 grams

The mass of the element X after decay = 28 grams

The function that represent the decay of element X is given as follows here;

[tex]y = a \cdot (0.5)^{\dfrac{t}{h} }[/tex]

Which is of the form;

[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]

Therefore;

h = 6 minutes = The time duration of the half life

a = N₀ = The initial mass = 390 g

N(t) = The final mass = 28 g

t = The time it takes the element to decay

Plugging in the values gives;

[tex]28 = 390 \times(0.5)^{\dfrac{t}{6} }[/tex]

[tex](0.5)^{\dfrac{t}{6} } = \dfrac{28}{390}[/tex]

Therefore;

[tex]\dfrac{t}{6} \times ln\left(0.5} \right) = ln \left(\dfrac{28}{390} \right)[/tex]

t/6 = ln(29/390)/ln(0.5)

t = 6 ×  ln(29/390)/ln(0.5) ≈ 22.496

Given the answer to the nearest tenth of a minute, the time it would take the element to decay to 28 grams, t ≈ 22.5 minutes.

There is no real solution of the equation.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Given is an equation x = 2 / (x-2) we need to find the solution,

x = 2 / (x-2)

x(x-2) = 2

x²-2x = 2

x²-2x-2 = 0

Using the quadratic formula, we get the solution of this equation,

x = 1±√3

Hence, there is no real solution of the equation.
