Answer 1

Answer:

7m^3-11m^2+5m+17

Step-by-step explanation:

it'll be really hard to show work so just trust me on this one-

hope it helps <3

Answer 2

For m^3 : Because you are subtracting a negative from a negative, that means you are adding, therefore the first part should be 7m^3

For m^2 : because you are subtracting a positive from a negative, that means you are subtracting, so it would be -11m^2

For m : because you are subtracting a negative from zero, it would turn into a positive, making it just 5

For the constant : subtracting positive 8 from negative 9 makes it a positive from the double negative. Therefore you would add 8+9, giving you 17

FINAL ANSWER : B. (7m^3)-(11m^2)+5m+17

Answers

Answer:

a) 7/12

b) 1/6

Step-by-step explanation:

(1)

Number greater than 5 include;

6, 7, 8, 9,10, 11, & 12

= 7

Probability of event = number of outcome ( total number of possible events )

= 7/ 12

(2)

Total number of possible events = 180 * 12

= 2160

Number of outcomes for;

Rolling a 3 = 1 * 120 / 2160 = 120/2160

Rolling a 9 = 1 * 120/2160 = 120/2160

Rolling a 11 = 1 * 120/2160 = 120/2160

120/2160 * 3

360/2160

= 1/6

Based on this data, what is a reasonable estimate of the probability that the next voter does not agree to the new amendment?

Answers

Answer:

The probability that the next voter does not agree to the new amendment is 0.2584 or 316/1223

Step-by-step explanation:

For this we have to subtract the number of voters who accepted the new amendment from the total number of voters

1223 - 907 = 316

To calculate the probability that someone will not vote in favor of the amendment we simply have to divide the number of negative votes by the number of total votes

316 / 1223 = 0.2584

The probability that the next voter does not agree to the new amendment is 0.2584

Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .

Answers

Answer:

A. Ruby added instead of divided

Step-by-step explanation:

You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer

12/15 times 15/2 equals 180/30 which, when simplified equals 6

Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

What is simplification?

Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15

Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Answers

Read the article "Voyages of Discovery:"Centuries ago, countries sponsored explorers to set sail for parts unknown and return with tales of new lands. These explorations led thqqqe Europeans to discover North America. The ocean journey from England, France, or Spain to North America was 3,000 miles of unknown dangers, but it led to discoveries. Explorers made these treacherous voyages for three main reasons: religion, wealth, and competition. These voyages of discovery began in the eleventh century.Historical records indicate that Leif Eriksson, a Viking explorer, was the first man to reach North Americaa around 1000. Leif is credited with landing along the coastline of present-day Newfoundland. A Viking settlement was established and occupied for several years before Eriksson left to return to his homeland. He died around 1020.Much later, Christopher Columbus left his homeland in 1492 to seek wealth in the form of trade items. The Italian explorer was destined for China but erred in direction and arrived on Watling's Islaaaaaaaaaaaaaaaaaaaaaaaaaaaaa a a a nd in the Bahamas. It was a long and dangerous journey. Upon arrival, Columbus dedicated the newly discovered land to the Spanish King and Queen of Aragon. Then, Columbus made three more voyages to North America in 1493, 1498, and 1502. To the very end, Christopher Columbus was adamant that he discovered a trade route to China. He denied ever being to North America.Credited with sailing around the southern tip of Florida, Spanish explorer Juan Ponce de Leon had several adventures in the New World. His journey around Florida occurred in 1513. At the time, he thought Florida was an island. When he returned to Florida in 1521, he was wounded by a poisoned arrow, which ultimately ended his life.Afterward, Hernando De Soto, a Spanish adventurer, left to explore present-day Florida in 1538. He and his men traveled thousands of miles through the South. They were the first Europeans recorded to have crossed the Mississippi River in 1541.Sir Walter Raleigh was a soldier, a writer, and a friend of the Queen of England. Around 1587, he sent English colonists to a region later called Virginia. The colony is believed to have been located in North Carolina. Since the people arrived together, their previous lifestyle and beliefs were transplanted to the New World.Finally, Rene Robert de La Salle was French. Historical data credits de La Salle as being the first explorer to traverse the Mississippi to its mouth at the Gulf of Mexico. He claimed the land that bordered the Mississippi River (about a third of present-day United States) for France on April 9, 1682. He built numerous forts along the route, but the settlers were often terrorized by the natives.These brave explorers from England, France, and Spain have left their legacy. As a result of their adventures, many people now enjoy North America's religious diversity, natural resources, and independence.Which sentence from the text helps the reader identify its structure?
