Answer:

$7.03

Step-by-step explanation:

3 times .89 equals 2.67. 4 times 1.09 equals 4.36. Add 2.67 and 4.36 then you get 7 dollars and 3 cents.

Answer:

7.03

Step-by-step explanation:

3 x 0.89 = 3.27

Answer:

B

Step-by-step explanation:

We can use the following co-function identity:

\(\sin(x)=\cos(90-x)\)

Substuting 35 for x yields:

\(\sin(35)=\cos(90-35)\)

Subtract:

\(\sin(35)=\cos(55)\)

Hence, our answer is B.

The profit-maximizing price and resulting profits are $36 and $0 respectively.

The profit-maximizing price for the monopoly will be to produce at the quantity where marginal revenue is equal to marginal cost.

Therefore, suppose the average total cost is $36 when q = 24, the profit maximizing price is as follows:

when Q = 24 at average cost = $36,

Then,

profit-maximizing price = p = $36

Hence, the resulting profit is as follows;

resulting profit = 36 - 36 = $0

The number completes the number sentence 3m= 5g.

The m refers the meatball which prices $2.50

so for 3m = 3*2.50

          3m = $7.5

g refers to grilled cheese which prices $1.50

so we have to find for how many grilled cheese which equals $7.5

On dividing we get, 7.5/1.50 = 5

Hence, in response to the provided question, we can say that As a result,  equation the item's selling price after both markdowns is 166.40$.

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

Then, we may determine the item's price after the initial 20% discount.

20% of 520$ equals (20/100) * 520$ = 104$, hence the item's new price is 520$ - 104$ = 416$.

After another six months of not selling, the item gets reduced by 60%.

60% of 416$ equals (60/100) * 416$ = 249.60$, therefore the item's ultimate sale price after both markdowns is 416$ - 249.60$ = 166.40$.

As a result, the item's selling price after both markdowns is 166.40$.

Using equations, we can find that the item's selling price after both markdowns is 166.40$.

In an algebraic equation, the equals symbol (=), which represents equality, can be used to connect two quotes. In algebra, an explanation is a declarative statement that establishes the similarity of two formulas. For example, the integers 3x + 5 and 14 are divided by the same letter.

A linear equation can be used to identify the relationship between the texts written on the various sides of a letter. Applications and products can typically be used interchangeably. In this instance, 2x – 4 = 2.

After applying the initial 20% discount, we may determine the item's price as:

20% of 520$ equals (20/100) × 520$ = 104$

Hence the item's new price is 520$ - 104$ = 416$.

After another six months of not selling, the item gets reduced by 60%.

60% of 416$ equals (60/100) × 416$ = 249.60$

Therefore, the item's ultimate sale price after both markdowns is

416$ - 249.60$ = 166.40$.

As a result, the item's selling price after both markdowns is 166.40$.

The cost of the television before the delivery charge and taxes is $452.40.

To determine the cost of the television before the delivery charge and taxes, we need to subtract those amounts from the total cost.

Delivery charge: $12

Taxes: 14% of the cost

Let's calculate the taxes first. The tax amount is found by multiplying the total cost by 14% (or 0.14):

Tax amount = 0.14 * $540 = $75.60

Now, we subtract the delivery charge and tax amount from the total cost to find the cost of the television before these additional charges:

Cost of television = Total cost - Delivery charge - Taxes

Cost of television = $540 - $12 - $75.60

Cost of television = $452.40

4 parallelogram- in order 2 find the area it must fulfill the parallelogram property. parallelogram r quadratic figure that opposite sides r equal. u give me 3 d/t length so it is difficult 2 answer the question.

the expected number of customers in the post office in steady state is 13.16.

We can use the M/M/1 queue model to solve this problem. Since customers arrive at a Poisson rate of 18 per hour, the arrival rate is λ = 18/60 = 0.3 customers per minute. The service times are deterministic, so we can use the mean service time to calculate the service rate. The mean service time is:

(0.5 x 2) + (0.2 x 3) + (0.3 x 5) = 3.1 minutes

So the service rate is μ = 1/3.1 = 0.3226 customers per minute.

The utilization of the system is ρ = λ/μ = 0.3/0.3226 = 0.929. Since the system is stable, the expected number of customers in the system in steady state is:

L = ρ/(1 - ρ) = 0.929/(1 - 0.929) = 13.16 customers

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

Answer:

General form of an exponential equation: \(y=ab^x\)

where:

Let x = years

Let y = investment value

Use (2, 692) and (4, 952) to find a and b of the exponential equation:

\(ab^2=692\)

\(ab^4=952\)

\(\implies \dfrac{ab^4}{ab^2}=\dfrac{952}{692}\)

\(\implies b^2=\dfrac{238}{173}\)

\(\implies b=\sqrt{\dfrac{238}{173}}=1.17\:\textsf{(nearest hundredth)}\)

\(\implies ab^2=a\left(\dfrac{238}{173}\right)=692\)

\(\implies a=\left(\dfrac{59858}{119}\right)=503.01\:\textsf{(nearest hundredth)}\)

Therefore, the exponential equation is:

\(y=503.01(1.17)^x\)

18 years after the initial investment is when \(x=18\):

\(\implies 503.01(1.17)^{18}=8490\)

Therefore, the amount closest to the value of the investment 18 years after the initial investment is $8490

The price of a postcard is 6 cents and Envelop is 8 cents.

Let's call the price of one postcard x.

The price of one envelope is x + 2 cents.

The total cost of the postcards is 15 * x cents.

The total cost of the envelopes is 10 * (x + 2) cents.

The total cost of both is 15 * x + 10 * (x + 2) cents.

This is equal to 170 cents.

We can set up the following equation to represent the information given in the problem:

15 * x + 10 * (x + 2) = 170

Solving for x, we find that the price of one postcard is:

It seems like there are no options to choose from, but if that is one of the options, here's how:

You can simplify ratios by finding if there is a common multiple.

For 35 and 100, there is a common multiple of 5, so you can divide both sides by 5 to simplify the equation.

That leaves us with 7:20. Since one is a prime number, we can't simplify this further.

It outlines the strategy for acquiring customers, establishing customer retention, developing the sales process, and setting prices that enable the business to make a profit.

It is important to consider that the company will only make a profit if the total revenue from sales is greater than the expenses. The cost of manufacturing and providing the service must be considered as well. The revenue from selling goods is reduced by the cost of producing those goods.

Now we want a blue one, the probability is computed in the same way, but now we have 5 blue ones and 14 in total (we already took one)
