The cost of the jersey that Charlotte wanted to buy  who is visiting to Brazil, in U.S. dollars based on the exchange rate is $16.39.

What is the exchange rate?

The exchange rate is the rate at which two nations currencies are exchanged in the foreign exchange market.

The exchange rate depends on the purchasing power of each currency.

Data and Calculations are as follows :

Cost of jersey = Br. 89

Exchange rate = $1 : Br. 5.43

Cost of jersey in US dollars = $ (Br. 89/Br. 5.43)

Thus, the cost of the jersey that Charlotte in U.S. dollars based on the exchange rate is B. $16.39.

Answer:

Step-by-step explanation:

You are given the equation 8x -3 +4x +3 = 180 and asked to simplify it and solve for x.

Collecting terms, we have ...

  (8 +4)x +(-3 +3) = 180

  12x + 0 = 180

Dividing by the coefficient of x gives ...

  x = 180/12 = 15

The value of x is 15.

The solution to this equation is x = 1, as 2log3x = 1 implies that log3x = 1/2, and then log3(x2 - 2) = 1/2.

The equation log3x log3(x2 2) = 1 2log3x can be simplified to log3x2 - log32 = 1 2log3x. This equation can be further simplified by combining like terms on both sides, resulting in log3x2 - 2log3x = log32. We can now take the logarithm of both sides, resulting in x2 - 2x = 2. This equation can be rearranged to x2 - 2x - 2 = 0, and then solved using the quadratic formula. The solutions of this equation are x = 1 and x = 2. However, since log3x must be positive, the only valid solution to the equation is x = 1. This implies that 2log3x = 1, and then log3(x2 - 2) = 1/2. Therefore, the solution to the equation log3x log3(x2 2) = 1 2log3x is x = 1.

Answer:  Therefore, we purchased 4 adult tickets and 7 child's tickets.

Step-by-step explanation:

Through the information provided, we set up a system equation:

a + c = 11

7.50a + 5.00c = 65

By the first equation, we convert it into a form, then we get a = 11 - c. Then we plug in the a = 11 - c to the second equation:

  7.50(11 - c) + 5.00c = 65

82.5 - 7.50c + 5.00c = 65

            82.5 - 2.50c = 65

                     - 2.50c = 65 - 82.5

                     - 2.50c = - 17.5

                               c = - 17.5/- 2.50

                               c = 7

And we plug c = 7 back into the first equation, which is a + c = 11.

a + c = 11

a + 7 = 11

      a = 11 - 7

      a = 4

Therefore, we purchased 4 adult tickets and 7 child's ticket.

B, a regular quadrilateral is named this way because it contains both the point and linear symmetry. By definition, a regular quadrilateral must have 4 equal sides and angles and must have its diagonals bisect each other.

Image 4:

The probability of the next child being a girl is 0.33.

What  is probability?

Probability is defined as how likely it is for an event to happen or for a statement to be true.

Main Body:

Total children = 3

Total girl child = 1/3 of total children

                       =(1/3)*3

                       = 1

Therefore total boys = 2

Probability of next child being girl = 1/3

                                                         =0.33

hence the answer is 0.33.

The answer choice which could not be modelled by an exponential function among the given answer choices is; A taxi charges a flat fee of $2.00 for pick-up, then an additional fee of 4.75 per mile.

It follows from the task content that the expression which could not be modelled by an exponential expression be identified among the answer choices.

An exponential function is one in which case the change factor is expressed as an exponent of the independent variable.

However, the function described as; A taxi charges a flat fee of $2.00 for pick-up, then an additional fee of 4.75 per mile is termed a linear model in which case;

The rate of change is constant and is equal to; $4.75 per mile.

Hence the required answer choice which cannot be modelled by an exponential function is; A taxi charges a flat fee of $2.00 for pick-up, then an additional fee of 4.75 per mile.

Answer:

Step-by-step explanation:

The question requires to find out how long it will take a hiker to make a complete circuit around the triangular trail with an average walking speed of 2 m/s.

The triangular hiking trail is given in the diagram below; The distance around the trail is the sum of all the three sides of the triangle. To find the length of each side of the triangle, we will apply the distance formula. Distance Formula The distance formula between two points (x₁, y₁) and (x₂, y₂) in a plane is given by;\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)For example, the length of side AC can be calculated as follows;\(AC=\sqrt{(20-0)^2+(10-0)^2}\)\(AC=\sqrt{(20^2+10^2)}\)\(AC=\sqrt{400+100}\)\(AC=\sqrt{500}\)\(AC=22.36\text{ m}\)Similarly,

The length of the other two sides can be calculated as follows; AB = 14.14 mBC = 20 m The perimeter of the triangle is the sum of all the three sides. P = AB + BC + AC P = 14.14 + 20 + 22.36 P = 56.5 m Hence, it will take a hiker more than 100 minutes to make a complete circuit around the triangular trail. Answer: More than 100

Given:

Raul's salary

Houston $ 70,000

Los Angeles $ 110,000 ( w 10% state tax)

Requird: actual % salary increase

Solution

Cost of the state tax = 10% ( $110,000) = (0.10) (110000) = $ 11, 000

The state tax will be deducted from his salary in Los Angeles, leaving him with only

The profit function P(x) = R(x) − C(x) is increasing on the interval 0 ≤ x ≤ 36, because the revenue function R(x) is increasing and the cost function C(x) is decreasing on that interval.

The grocery chain has a cost and revenue model that is determined by the following functions: C(x)=1.2x−0.012x2, 0≤x≤150 and R(x)=3.6x−0.06x2, 0≤x≤150. The cost function C(x) is decreasing on the interval 0 ≤ x ≤ 150 and the revenue function R(x) is increasing on the interval 0 ≤ x ≤ 150. Therefore, the profit function P(x) = R(x) − C(x) is increasing on the interval 0 ≤ x ≤ 36, because the revenue function is increasing faster than the cost function is decreasing. This means that the profit increases as the number of units sold increases from 0 to 36. Beyond 36 units, the cost function decreases faster than the revenue function increases and so the profit decreases.

There are four levels of measurements in statistics, namely nominal, ordinal, interval, ratio. These levels are important when it comes to analyzing data, since it helps us determine the technique that we can use to support or refute our study.

In the nominal level, we can categorize data but they cannot be ranked. An example would be hair color. In an ordinal data, the data can be both categorize and ranked, but doing mathematical calculation may not make sense. Also, the intervals between rankings doesn't necessarily dictate how close or far apart the data are.

A good example is level of education. In an interval level, the data can be categorized, ranked, and measured but they do not have a true zero. An example could be a range of values that does not include zero. Lastly, in the Ratio level the data can be categorized, rank, and measured, and it has a true zero.

So ratio level is most appropriate for ages of children. Note that ages can be categorized, rank, and measured .Moreover, an age equal to zero means that there is no age or the absence of age.

Step-by-step explanation:

Since this is a series of events probability question, in order to calculate the probability you need to first find the probability of getting each individual answer right and then multiplying those probabilities together. This will give you the probability of getting 100% on the entire test. Since the questions are multiple-choice with 4 choices and only 1 correct choice then the probability of getting one right is 1/4 or 25%. Now that we have that probability we simply need to multiply it 5 times for each individual question.
