For the given situation: Derek has $20 to spend on used books. Hardcover books cost $5 each and paperbacks cost $2 each. What equation in standard form determines the number x of hardcover books and the number y of paperback books he can buy? Select all the pairs that represent combinations of books that Derek can buy. Group of answer choices (2, 5) (0,10) (−2, 15) (3, 5/2) (1, 2/5)

Answers

Answer:

(0,10)

Step-by-step explanation:

All of  the other answers dont make sense or are false so it makes (0,10) the only correct answer.

The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible thus options (A) and (B) is correct.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

As per the given,

Hardcover books cost $5 each and paperbacks cost $2 each.

The number of hardcover books is x while paperbacks are y

Thus,

Total cost = 5x + 2y

5x + 2y ≤ 20

The x and y is the whole number so they will never be negative or in fractions.

Therefore, The pair which satisfies the above expression is (2,5) and (0,10).

Hence "The equation represents the situation is 5x + 2y ≤ 20 so pair (2,5) and (0,10) is possible".

Tiffany wants to calculate the volume of her globe. The globe is in the shape of a sphere. She measured the circumference of the globe along the equator to be 24 inches. What is the volume of the globe? Round your answer to the nearest whole number.

Answers

Answer:

231in^3

Step-by-step explanation:

We know that the volume of a sphere/globe is given as

V=4 /3πr^3

but the circumference is expressed as

C=2πr

solving for r given  that C=24

24=2*3.142r

24=6.284r

r=24/6.284

r=3.8in

put r=3.6 in the expression for volume we have

V=4 /3π(3.8)^3

V=4 /3π(55

V=(220.59*3.142)/3

V=693.12/3

V=231in^3

The volume of the globe is 231in^3

The volume of the globe is 233  cubic inches.

Important information:

Circumference of the globe along the equator to be 24 inches.

We need to find the volume of the globe.

Volume of sphere:

Let [tex]r[/tex] be the radius of the globe.

Circumference of the globe along the equator is:

[tex]C=2\pi r[/tex]

[tex]24=2\pi r[/tex]

[tex]\dfrac{24}{2\pi }=r[/tex]

[tex]\dfrac{12}{\pi}=r[/tex]

Volume of the globe is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

[tex]V=\dfrac{4}{3}\pi \left(\dfrac{12}{\pi}\right)^3[/tex]

[tex]V=\dfrac{4}{3}\pi \left(\dfrac{1728}{\pi^3}\right)[/tex]

[tex]V=233.444...[/tex]

[tex]V\approx 233[/tex]

Therefore, the volume of the globe is 233  cubic inches.

Josue knows that his aunt earns more money. than his uncle. He asked how much his aunt earns each month and was told, "$600 less than twice what your uncle earsn." If his aunt earns $4,200 per month, how much money does his uncle earn each month?

Answers

Answer:

Uncle's earnings is $2400

Step-by-step explanation:

Represent his uncle's earnings with x

$600 less than twice what your uncle earns is represented as:

[tex]2x - 600[/tex]

Since, his aunt's earnings is $4200.

We have:

[tex]2x - 600 = 4200[/tex]

Add 600 to both sides

[tex]2x - 600 + 600= 4200 + 600[/tex]

[tex]2x = 4800[/tex]

Solve for x

[tex]x = 4800/2[/tex]

[tex]x = 2400[/tex]

Hence, His uncle's earnings is $2400

What is the difference between naming a segment and writing its distance?

Answers

Answer:

Explained below

Step-by-step explanation:

In naming a segment, we are essentially naming a line that has definite starting and endpoints. For example if the starting point of the segment is A and the endpoint is B, we can name it "segment AB".

In another example, a segment can be named with a single letter. For example the point from A to B can be referred to as "segment y" if AB is part of maybe a square.

Whereas, in writing a distance, we are essentially writing the measurement of length between the two endpoints. For example if the distance between AB is 20 metres, we can write distance between AB = 20 metres

The holcombe family went out to dinner the meal cost 54.65 the sales tax is 8 peecent the tip was 18 percent of the meal and tax there are 5 people in the holcomebe family what was the cost per person for the meal including sales tax and tip

Answers

Answer:

13.93

Step-by-step explanation:

Meal = 54.65

Sales tax = 8%

= 8/100 * 54.65 + 54.65

= 0.08 * 54.65 + 54.65

= 4.372 + 54.65

= 59.022

Tip = 18% of the meal and tax

= 18/100 * 59.022 + 59.022

= 0.18 * 59.022 + 59.022

= 10.62396 + 59.022

= 69.64596

Total people in the holcomebe family = 5

Cost of meal per person =

69.64596 / 5

= 13.929192

Approximately 13.93
