at a yard sale you find 5 paperback books by your favorite author. each book is $0.75. write a rule for the amount (in dollars) you spend as a function of the number of books you buy.

Answers

Answer 1
y = 0.75x....where y is the total cost and x is the number of books

or it could be f(x) = 0.75x...in function notation
Answer 2

The function for the amount of money left after buying books is y = 10 - 0.75x.

Let x represent the number of books you buy. Each book costs $0.75, so the total cost for x books is 0.75x. You start with $10.

Therefore, the amount of money you have left, y, can be represented by the function:

y = 10 - 0.75x

For example, if you buy 3 books, the remaining money would be:

y = 10 - 0.75(3)

= 10 - 2.25

= 7.75

The complete question is:

At a yard sale, you find 5 paperback books by your favorite author.  You have $10 in each book is priced at $0.75. Write a rule for the amount of money you have left as a function of the number of books you buy.

Mulch to cover a rectangular garden costs $48. Mulch is needed to cover a larger, similar garden. The ratio of dimentions is 2:3. How much would it cost to cover the larger garden?

A) $288
B) $192
C) $72
D) $108

Answers

The cost of covering the larger garden is $192. So option (b) is correct.

To solve this problem, let's first find the dimensions of the larger garden.

Given that the ratio of dimensions between the two gardens is 2:3, let's assume the dimensions of the smaller garden are 2x and 3x, where x is a common factor.

So, the smaller garden's area is (2x) * (3x) = 6x².

Now, let's find the area of the larger garden. Since the ratio of dimensions is 2:3, the dimensions are 2(2x) and 3(2x), which are 4x and 6x.

Thus, the larger garden's area is (4x) * (6x) = 24x².

Now, since the cost of mulch is directly proportional to the area, we can set up a proportion to find the cost.

(6x²) / (24x²) = $48 / Cost of covering the larger garden

Solving for the cost of covering the larger garden:

Cost of covering the larger garden = ($48 * 24x²) / (6x²)

= $192

So, the correct answer is B) $192.

If a real estate agent receives 11 percent of the selling price of each house he sells, then what would the agent make if the house sells for $1033,000?

Answers

if you take the percentage out of 1,033,000 you get the answer $113,630

The real estate agent would make $113,630 by earning an 11% commission on the sale of a house priced at $1,033,000.

The real estate agent would receive 11% of the selling price of the house if it sells for $1,033,000. To calculate the commission, we use the formula:

Commission = Selling Price  imes Commission Rate

So, the agent's commission would be:

Commission = $1,033,000  imes 0.11 = $113,630.

Therefore, the real estate agent would make $113,630 from the sale of the house.

Divide each cost over the number of bottles

For the 6-pack, we have
3.79 dollars divided by 6 = 3.79/6 = 0.6317 which rounds to 0.63

So we pay $0.63 per bottle or 63 cents per bottle

-------------------------------------

For the 9-pack, we have
4.50 dollars divided by 9 = 4.50/9 = 0.50

meaning we pay $0.50 per bottle or 50 cents per bottle
-------------------------------------

For the 12-pack, we have
6.89 dollars divided by 12 = 6.89/12 = 0.57416 which rounds to 0.57

So we pay $0.57 per bottle or 57 cents per bottle
-------------------------------------

In summary we have
The 6-pack costing 63 cents per bottle
The 9-pack costing 50 cents per bottle
The 12-pack costing 57 cents per bottle

The lowest per bottle cost is 50 cents per bottle, which is for the 9-pack

A Term is a small group of whole equation. for example, the terms in this problem would be 6pq, 8p, and -6r.
A constant is a number by itself, so with no number behind it.

Square X is similar to square Y. The scale factor from square X to square Y is 2.5. The area of square X is 25 cm². What is the area of square Y?

Answers

if scale factor is 2.5 then ratio of the areas = 1:2.5^2  = 1 : 6.25, so:-

Area  of square Y = 25 * 6.25  =  156.25 
Final answer:

The area of square Y is 156.25 cm².

Explanation:

To find the area of square Y, we need to use the scale factor to determine its dimensions. The scale factor is 2.5, which means the side length of square Y is 2.5 times the side length of square X. Since the area of square X is 25 cm², we can calculate the side length of square X by taking the square root of 25, which is 5 cm. Therefore, the side length of square Y is 5 cm * 2.5 = 12.5 cm. The area of square Y is then calculated by squaring its side length: 12.5 cm * 12.5 cm = 156.25 cm².

A. 89 fl oz

C. 10 fl oz
D. 33 fl oz

Answers

there are 33.841 fluid ounces in a liter so 33.841 x 3 is approximately 101 fl oz.

Answer:

B. 101 fl oz

Step-by-step explanation:

We have been that some doctors recommend that men drink 3 liters of water every day . There are approximately 29.6 milliliters in 1 fluid ounce.

We know that 1 liter equals 1000 ml.

3 liters = 3,000 ml.

To find the number of fluid ounces in 3 liters, we will divide number of milliliters in 3 liters by number of milliliters in 1 fluid ounce.

[tex]\text{The number of fluid ounces in 3 liters}=\frac{3000}{29.6}[/tex]

[tex]\text{The number of fluid ounces in 3 liters}=101.35135135\approx 101[/tex]

Therefore, there are 101 fluid ounces in 3 liters of water and option B is the correct choice.

The hotel that the Hutchinson family is staying at on the vacation is shaped like a rectangle prism it is 234 feet long 158 feet wide and 37 feet tall what is the volume of the hotel

Answers

Final answer:

The volume of the hotel that the Hutchinson family is staying at, which is shaped as a rectangular prism, can be found by multiplying its length (234 feet), width (158 feet), and height (37 feet) to get a total volume of 1,371,132 cubic feet.

Explanation:

The hotel that the Hutchinson family is staying at can be considered as a rectangular prism when trying to calculate its volume. The formula for calculating the volume of a rectangular prism is Volume = length × width × height.

The given dimensions of the hotel are 234 feet (length), 158 feet (width), and 37 feet (height). Thus, the volume of the hotel can be calculated by multiplying these dimensions together:

Volume = 234 feet × 158 feet × 37 feet

Calculating, we get:

Volume = 1,371,132 cubic feet.

Therefore, the volume of the hotel is 1,371,132 cubic feet.

An airplane takes 4 hours to travel a distance of 2600 miles with the wind. The return trip takes 5 hours against the wind. Find the speed of the plane in still air and the speed of the wind.

Answers

2,600/4 =650
650•5 =3,250


I found the unit rate of the 2,600 by dividing the per hour and then times it by the 5 hours

Hopefully that was what you were looking for

The speed of the plane in still air = 585 mph

and the speed of the wind = 65 mph

What is speed?

"It is the distance covered per unit time."

What is the formula of speed?

"speed = distance/time"

For given question,

Let, the speed of the airplane in still air = x mph

and the speed of the wind = y mph

So, the speed of the airplane with the wind = (x + y) mph

and the speed of the airplane against the wind = (x - y) mph

Here, the distance (d) = 2600 miles

An airplane takes 4 hours to travel a distance of 2600 miles with the wind.

[tex]\Rightarrow x+y=\frac{2600}{4} \\\\\Rightarrow x+y=650~~~~~~~~~~.........................(i)[/tex]

The return trip takes 5 hours against the wind.

This means, an airplane takes 5 hours to travel a distance of 2600 miles against the wind.

[tex]\Rightarrow x-y=\frac{2600}{5}\\\\ \Rightarrow x-y=520~~~~~~~~~~............................(ii)[/tex]

From equation (ii),

x = 520 + y                ........................(iii)

Substitute this value in equation (i),

⇒ (520 + y) + y = 650

⇒ 2y = 650 - 520

⇒ 2y = 130

⇒ y = 65 mph

Substitute the value of y in equation (iii),

⇒ x = 520 + y  

⇒ x = 520 + 65

⇒ x = 585 mph

Therefore, the speed of the plane in still air = 585 mph

and the speed of the wind = 65 mph
