a high school club is researching a tour package offered by the island kayak company. the company charges $35 per person and $245 for the tour guide. which function represents the total cost, c(x), of this kayak tour package for x club members? A. C(x) = 35x B. C(x) = 35x+245 C. C(x) = 35(x+245) D. C(x) = 35 + (x+245)

Answers

The function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x

How to calculate the total cost on a package?

According to the given question, we have the following parameters

Amount charged on tour guide = $245

Let the total number of club members charged be "x", such that if the company charges $35 per person, the total cost on "x" members will be 35x

Determine the total cost

Total cost =  Amount charged on tour guide + cost of "x" members

Total cost = 245 + 35x

Hence the function that represents the total cost, c(x), of this kayak tour package for x club members is 245 + 35x

Omar and Zina Aboud found that the dealer's cost of the base price was $16,558. 16 and the dealer's options cost was $611. 60. The consumer paid the $475. 00 destination charge. If the percent of the dealer's cost is 92% and the percent of dealer's options cost is 88%, find the car's sticker price

Answers

Assuming the percent of the dealer's cost is 92% and the percent of dealer's options cost is 88%, The car's sticker price is: $17,644.76 and the dealer price is $16,246.72.

Car's sticker price and dealer's price

a. Car's sticker price:

Using this formula

Car's sticker price=Base price+Options cost+Destination charge

Let plug in the formula

Car's sticker price=$16,558. 16 + $611. 60+$475. 00

Car's sticker price=$17,644.76

b. Dealer price:

Dealer's price=Percent of base price+Percent of options cost+Destination charge

Let plug in the formula

Dealer price=16,558. 16+$611. 60+$475.00

Dealer price=$16,246.7152

Dealer price=$16,246.72 (Approximately)

Two siblings, Miko and Cheko, receive some pocket money every month. This month, the ratio of Miko's pocket money to Cheko's pocket money is 8:12. Cheko's pocket money is $660. How much must Cheko give to Miko such that each of them have an equal amount of pocket money?

Answers

Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio of Miko's pocket money to Cheko's pocket money.

= 8:12

= 2:3

Now,

Let's represent Miko's pocket money as 2x and Cheko's pocket money as 3x.

We know that,

3x = $660
x = $220

Miko's pocket money.

= 2x

= 2($220)

= $440.

To make their pocket money equal,

Cheko needs to give half of the difference between their pocket money to Miko.

The difference between their pocket money.

= $220 (i.e., $660 - $440).

Half of that is $110.

Therefore,

Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.

What is the slope of a line that passing through the points ( 6 , -10 ) and ( 8, -18) ?

Answers

Answer:

Slope = -4

Step-by-step explanation:

Given:

Point 1: (6,-10)Point 2: (8,-18)

Rate of change (Slope) formula:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1} }[/tex]

Where:

y₂ = y-coordinate of second point = -18y₁ = y-coordinate of first point = -10x₂ = x-coordinate of second point = 8x₁ = x-coordinate of first point = 6

Substitute the coordinates of the given points in the formula to determine the slope of the line (Rate of change).

[tex]\implies \text{Slope} = \dfrac{(-18) - (-10)}{8 - 6 }[/tex]

Finally, let's simplify the fraction on the right hand side as needed.

[tex]\implies\text{Slope} = \dfrac{(-18) + 10}{8 - 6 }[/tex]

[tex]\implies \text{Slope} = \dfrac{-8}{2 } = -4[/tex]

Therefore, the slope of a line that passes through (6 , -10 ) and (8, -18) is -4.

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.
Find the base and the height of the triangle.

Answers

Answer:

b = 10 ft , h = 6 ft

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

let base = b theh height h = b - 4

given A = 30 , then

[tex]\frac{1}{2}[/tex] b(b - 4) = 30 ( multiply both sides by 2 to clear the fraction )

b(b - 4) = 60 ← distribute parenthesis on left side by b

b² - 4b = 60 ( subtract 60 from both sides )

b² - 4b - 60 = 0

(b - 10)(b + 6) = 0

equate each factor to zero and solve for b

b - 10 = 0 ⇒ b = 10

b + 6 = 0 ⇒ b = - 6

however, b > 0 , then b = 10

and h = b - 4 = 10 - 4 = 6

then base is 10 ft and height is 6 ft

Answers

The area of the rhombus with length of diagonals 12 cm and 12 cm is 72 centimetre squared.

Area of a rhombus

The area of a rhombus can be represented mathematically as follows:

area of a rhombus  = ab / 2

where

a and b are the length of the diagonal

a = 6 + 6 = 12 cm

Therefore, let's find b

tan 45 = opposite / adjacent

tan 45 = 6 / x

x = 6 / tan 45

x = 6 / 1

x = 6

b = 6 + 6 = 12 cm

Which equation is represented by the graph below?
i’ll make brainlyesttttt

Answers

Answer:

y=e^x - 4

Step-by-step explanation:

The log functions decrease with increasing x.  The line shown increases as x increases, so it must be one of the two e^x equations.  We can decide which one by calculating which equation povides the correct values to match the two points the curve crosses the y and x axes.

The graph shows the line crossing the y axis at -3 (0,-3)

It shows it crossing the x axis at a little over 1, perhaps 1.4 (1.4,0).  

When x=0, e^0 = 1.  

Look at the point (0,-3):  

We know the e term will be 1 (e^0 = 1), so for y to be -3, we need to subtract 4:  The form e^x - 4  would yield a value for y, when x is 0, of y = 1 - 4 or -3.

Check the other point (1.4,0):

y = e^1.4  is equal to 4.00

y = 4.00 - 4

y = 0

This point is also correct (1.4,0)

The correct equation is y=e^x - 4

Answers

Answer:

Median = 58.5

Q1 = 55

Q3 = 65

Interquartile = 10

Step-by-step explanation:

first let’s correct the data set :

It’s 38 46 55 56 58 59 61 65 67 75  not   38 46 55 56 558 59 61 65 67 75

Data set : 38 46 55 56 58 59 61 65 67 75

Median:

After we put Our data set from Smallest to largest

we define the median as the middle number of the data set but our set consists of an even number which is 10

In this case the median is the average of the two middle numbers which are the 5th and 6th numbers

38 46 55 56 [58 59] 61 65 67 75

Then

Median = (58+59)/2 = 117/2 = 58.5

quartile 1 : It’s just the median of the lower set of numbers which means it’s the median of : 38 46 55 56 58

Then Q1 = 55 because it’s the middle number.

quartile 3 : It’s just the median of the upper set of numbers which means it’s the median of : 59 61 65 67 75

Then Q3 = 65  (Easy to spot)

Interquartile = Q3 - Q1 = 65 - 55 = 10
