The value of the sales tax applied to the bill is $0.36

If we have an initial value A, and we increase it by a percentage X, then the new value (after the increase) is given by:

A' = A*(1 + X/100%).

Here we know that the bill before the tax and the tip (it will be the initial value) is:

A = $11.85

And a sales tax of 3% is applied to that bill, then the new amount is:

A' = $11.85*(1 + 3%/100%)

A' = $11.85*(1 + 0.03) = $12.21

The sales tax is equal to the difference between the amount above and the initial value of the bill.

tax = $12.21 - $11.85 = $0.36

Answer:

[tex]\dfrac{155}{18} \pi \textrm{ cm}[/tex]

Step-by-step explanation:

This problem asks us to find the length of an arc ACB on the circumference of a circle with center O and a radius of 5 cm.

We first must solve for the total circumference (perimeter) of the circle. This is represented by the formula C = 2πr. Hence, the circumference of this circle is:

C = 2π(5) cm

C = 10π cm

Next, we have to find what fraction of 360º the major arc ACB is in order to deduce how much of the circle's total circumference the arc takes up.

[tex]\dfrac{(360 - 50)\textdegree}{360\textdegree} = \dfrac{31}{36}[/tex]

Finally, we can multiply the amount of circumference that arc ACB takes up by the length of the whole circumference to get the length of arc ACB.

[tex]\textrm{Length of arc } ABC = \dfrac{31}{36} \cdot 10\pi[/tex]

[tex]= \dfrac{310}{36} \pi[/tex]

[tex]= \dfrac{155}{18} \pi \textrm{ cm}[/tex]

Answer:

[tex]\textsf{Length of major arc $\overset{\frown}{ACB}$}: \;\; \boxed{\dfrac{155}{18}\pi\; \sf m}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $= \pi r\left(\dfrac{\theta}{180^{\circ}}\right)$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in degrees.\\\end{minipage}}[/tex]

Angles around a point sum to 360°.  Therefore:

[tex]\begin{aligned}\implies m \angle BOA&=360^{\circ}-m \angle AOB\\&=360^{\circ}-50^{\circ}\\&=310^{\circ}\end{aligned}[/tex]

Therefore, the given values are:

To find the length of the major arc ACB, substitute the given values into the arc length formula:

[tex]\begin{aligned}\implies \overset{\frown}{ACB}&=\pi \cdot 5 \cdot \left(\dfrac{310^{\circ}}{180^{\circ}}\right)\\\\&=5\pi \cdot \dfrac{31}{18}\\\\&=\dfrac{155}{18}\pi\; \sf m\end{aligned}[/tex]

On solving the provided question, we can say that  equation that has a solution of 4 is -8+16=0

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

If we solve   -8+16=0, we get

-4-4n+16=0

(-4)-4(-4)=0

(-4)(-4)=0

which give -4=0

=4

The inequality which represents the number of backpacks need to be sold is 40x - (10x + 12,000) ≥ 980. Factory should sell at least 433 backpacks in a week.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Selling price of 1 backpack = $40

Cost to make 1 backpack = $10

Operating expense per week = $12,000

Let x be the number of backpacks which are sold in a week.

Total revenue per week = 40x

Total expense per week = 10x + 12,000

Profit = Revenue - Expense

         = 40x - (10x + 12,000)

Factory's goal is to make a profit of at least $980 each week.

40x - (10x + 12,000) ≥ 980

This is the inequality that represents the number of backpacks need to be sold.

Solving the inequality,

40x - (10x + 12,000) ≥ 980

40x - 10x - 12,000 ≥ 980

30x ≥ 980 + 12,000

30x ≥ 12,980

x ≥ 432.67 ≈ 433

Hence factory must at least a total of 433 backpacks to meet it's weekly goal of $980.

A: To find the intersection of the sets A and B, we need to find the elements that are common to both sets.

A = {x ∈ ℕ : 2 ≤ x < 19}

B = {x ∈ ℕ : x is even}

The intersection of the sets A and B is {x ∈ ℕ : 2 ≤ x < 19, x is even}

∩ = {4,6,8,10,12,14,16,18}

B: To find the difference of the sets A and B, we need to find the elements that are in set A but not in set B.

A = {x ∈ ℕ : 2 ≤ x < 19}

B = {x ∈ ℕ : x is even}

The difference of the sets A and B is {x ∈ ℕ : 2 ≤ x < 19, x is not even}

∖ = {3,5,7,9,11,13,15,17}

So the solution for A is ∩={4,6,8,10,12,14,16,18} and for B is ∖={3,5,7,9,11,13,15,17}

An equation is a expression that shows the relationship between numbers and variables.

The standard form of a linear equation is:

Where m is the rate of change and b is the y intercept

Let y represent the amount of sodium silicate in x ml of liquid soap.

From the graph, using the points (1000, 100) and (3000, 300):

y - 100 = [(300 - 100)/(3000 - 1000)](x - 1000)
