c=11

Step-by-step explanation:

8+9+12+c/4= 10

17+12+c/4=10

29+c/4=10

29+c=40

c=40-29

c=11

Answer:

I THINK its 11

Step-by-step explanation:

Mean is just average and if you add the cars sold in the first 3 months it equals 29. we need an average of 10. 40 divided by 4 is 10. we divide by for because it is the number of months. to get to 40 overall cars, he would need to sell 11 cars in the 4th month.

f(x) = (x - 7)(x + 8)

To obtain the zeros , let f(x) = 0, that is

(x - 7)(x + 8) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 8 = 0 ⇒ x = - 8

A truck can be rented from Company A for ​$110 a day plus ​$0.80 per mile. Company B charges ​$30 a day plus ​$0.90 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Company A a better deal than Company​ B's?

Answers

Answer:

800 miles

Step-by-step explanation:

Let the number of miles be represented by x

Company A for ​$110 a day plus ​$0.80 per mile.

$110 + $0.80 × x

110 + 0.80x

Company B charges ​$30 a day plus ​$0.90 per mile to rent the same truck.

$30 + $0.90 × x

30 + 0.90x

110 + 0.80x = 30 + 0.90x

110 - 30 = 0.90x - 0.80x

80 = 0.1x

x = 80/0.1

x = 800 miles

800 miles driven per day makes the rental cost for Company A a better deal than Company​ B's

DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked of the original price, but it was really off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?

Answers

Answer:

 $24

Step-by-step explanation:

The question is not complete, here is the complete question

"DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"

SolutionTake note of the words "of" and "off"

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost per bracelet = 1.50

Cost per necklace = 2.25

Let :

number of necklace = n

Number of bracelet = b

Cost equation C ;

C = 1.5b + 2.25n

Number of necklace that could be sold for exactly $12

5 necklaces and 1 bracelet :

1.5 + 2.25(5) = 12.75

•2 necklaces and 5 bracelets:

1.5(5) + 2.25(2) = 12

• 3 necklaces and 3 bracelets

1.5(3) + 2.25(3) = 11.25

• 4 necklaces and 2 bracelets

1.5(2) + 2.25(4) = 12

• 3 necklaces and 5 bracelets

1.5(5) + 2.25(3) = 14.25

• 6 necklaces and no bracelets •

1.5(0) + 2.25(6) = 13.5

No necklaces and 8 bracelets

1.5(8) + 2.25(0) = 12

Amount charged per Tshirt = c

Setup fee = $40

Number of students in drama club = 21

Total cost of order = $187

Calculate C ;

Total order cost = set up fee + (cost per shirt * number of shirts)

Total order cost = 40 + 21c

187 = 40 + 21c

187 - 40 = 21c

147 = 21c

c = 147 / 21

C = 7

Hence cost per shirt = $7

Will someone check and see if it is good enough to seem like I tried? Marco Polo (1254-1324) is likely the most renowned westerner who travelled on the Silk Road. He excelled past all other travelers in his decision, work, and effect. The travels of his through the continent lasted 24 years, and he hit farther than any of his forerunners, beyond Mongolia, to Taiwan. He turned into a friend of Kublai Khan, and travelled the whole of Taiwan and returned to tell his story, which eventually turned into a great travelogue. A citizen of the commonwealth of Venice, Polo grew up in a household where both his dad Niccolo and Uncle Maffeo were Merchants. Even before Marco was born, these brothers had journeyed extensively, setting up trading posts as Istanbul, Sudak, Crimea, and the West portion of the Mongol monarchy. They still visited Taiwan occasionally. His dad, Niccolo, traded with the Near East, and grew rich, attaining great prestige. Niccolo and Maffeo set off on the trading journey, just before Marcos own first expedition. In 1260, Niccolo and Maffeo, while residing in Istanbul, then the capital of the Latin Monarchy, anticipated the governmental effect. They liquidated their possessions into jewels and relocated themselves elsewhere. According to the Travels of Marco Polo, they fell through some of the continent, and met with Kublai Khan, the Mongolian ruler and father of the Yuan Dynasty. Their decision to make Constantinople proved to be timely. "The Travels of Marco Polo" turned into a largely popular novel. It was translated into several languages and spread all throughout Egypt. After the decline of Kublai Khan, the Ming Dynasty was the next great empire. They were largely suspicious of any traveller, and little information was free. This made the Novel even more fashionable. His Novel presents a wide and vast-extending display of Kublai Khan's thirteenth century realm. Marco Polo is the Great Khan's messenger who is appointed to go all through his domain. Marco Polo is sent to research and report back his discoveries about individuals, customs, culture, atmosphere, widely varied vegetation, game, winged animals and residence. The Great Khan's realm ranges from the Mideast and the Levant east through all the grounds and realm to the China Sea and islands in it, north to Russia and the polar area and south to the Indian Ocean islands. Marco Polo is accepted to travel farther and more broadly than any other person in the realm of his day. Polos choice to travel was paved by the pioneering endeavors of his ancestors, specifically his dad Niccolo, and his Uncle, Maffeo. His family had dealt with the Middle East for an extension of time, gaining significant wealth and prestige. Although it is questionable if the Polos were of nobility, this was of small value in Venice, the city of Republican and mercantile traditions. This time period was also known as the Golden age of Venice. They left home in 1271 and eventually returned there in 1295. A few years afterwards, Venice defended the battle with the city of Genoa. Marco was place under seizure. While under arrest, Marco told detailed tales of his journeys to an author, whom was named Rustichello, who took note of all of them, and published them in the novel, The Traveling Of Marco Polo. The discovery of the New World, the colonization of the Americas, the American Revolution, and the modern era: all of these great events in humanity may not have occurred in the same way or at all if it was not for one of historys greatest explorers. He traveled the Silk Road, enlightened Europeans to the ways of the East, and inspired future explorers who would be filled with his same drive to catalog the unknown. Yes, history would not have been the same without Marco Polo.
