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.

A) 15

Step-by-step explanation:

PEMDAS

20 / 4 + (6 * 2) - 2

take out the parenthesis which is P

20 / 4 + 12 - 2

there is no E

the go the rest of the way MDAS

5 + 12 - 2

17 - 2

15

Answer:

15 (A)

Step-by-step explanation:

ok first off you have to remember PEDMAS parentheses,exponents,division.multiplication,addition.subtraction(D and M are from left to right, as well as A and S.)

so the first thing you have to do is 6*2 because it is in the parentheses

this equation turns into

20/4+12-2

now do the division

5+12-2

now you have to add because it is left to right (it doesn't really matter what you o first in this situation)

17-2

15 (A)

hope this helps! have a nice day :)

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.

Answer:

y=-3/2x+2

Step-by-step explanation:

You can find the equation using y=mx+b, where m is the slope and b is the y-intercept. You can see the slope of this line is -3/2, and the y-intercept is 2. If you plug that into the equation, you get y=-3/2x+2

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

14 2/5x-2/15=-1 23/25

Answer: what he said

Step-by-step explanation:

The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the coordinate of the point be represented as B

The value of B = B ( -10 , -6 )

Now , the dilation factor is given by k = 1/2

So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get

The coordinate of the point B' after the dilation is

B' = B' ( -10/2 , -6/2 )

So , on simplifying the equation , we get

B' = B' ( -5 , -3 )

Hence , the point after dilation is B' ( -5 , -3 )

36 fishes

Step-by-step explanation:

Step 1

Nanette goes fishing. Of the fish Nanette catches, 2/3 are catfish.

Let the total fraction of fish = 1

The fraction of fish that is not catfish is

1 - 2/3

= 1/3

Step 2

She catches 12 fish that are not catfish.

Let the total number of catfish = x

Hence,

1/3 × x = 12

Equation is given as:

x/3 = 12

Cross Multiply

x = 3 × 12

x = 36 fishes

The the total number of fish, x that Nanette catches is 36 fishes

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.

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.

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.

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
