Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?
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.

What does natural log mean?A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x.Euler's Number, e, came before logarithms.One of the most significant mathematical constants, e, is an irrational number that is intimately connected to growth and pace of changeNatural logarithm Rules :
ln (mn) = ln m + ln nln (m/n) = ln m - ln nln [tex]m^{n}[/tex]= n ln mln a = (log a) / (log e)ln e = 1ln 1 = 0so we can rewrite the expression :
ln(400) = ln([tex]4^{2} . 5^{2}[/tex])= ln [tex]4^{2} + ln 5^2[/tex]= [tex]2( ln 4 + ln 5)[/tex]

Find the value of x please!! ASAP
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.

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.

IN THE DIAGRAM the measures of <2,<3 and <6 are 40 THE measure of <1 is 140 . Are lines c & d parallel
Step-by-step explanation:
the answer is D
Yes, the lines are parallel.
What are parallel lines?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.

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

Answer:
d
Step-by-step explanation: bc i said
The possible error of measurement is half of the smallest unit on the tape measure, which is half an inch, option B is correct.
What is Equation?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.

Nanette goes fishing. Of the fish Nanette catches, 2/3 are catfish. She catches 12 fish that are not catfish. Which equation and solution represent the total number of fish, x, Nanette catches?
Answer:
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

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.

Mr. Mann asked his class to form a number pattern using the rules:
Use the number 6 as the first term.
To find the other term, subtract 2 from the previous term, then multiply by 2.
The first two numbers in the pattern are 6 and 8.
What is the fourth number in the pattern?
Answer:
20
Step-by-step explanation:
when you subtract 2 from 6 you get 4. so you multiply 4 into 2 which give the answer 8. when you subtract 2 from 8 you get 6 and then you multiply 6 to 2 which gives the answer 12... next you subtract 2 from 12 which gives the answer 10. so you multiply 10 to 2 Which gives the final answer for you which is 20.
