Answers

Answer:

x = 8

Step-by-step explanation:

Recall: Ratio of the corresponding side lengths of two similar figures are equal.

Therefore,

EF/AB = GH/CD

6/4 = 12/x

Cross multiply

6*x = 12*4

6x = 48

Divide both sides by 6

6x/6 = 48/6

x = 8

This inequality will be correct if x is less than or equal to 17. Meaning any number less than 17 and including 17 will make the equation correct. For this reason you pick the one with a filled circle. The answer is H

Mr. Tough can grade the final exams in 12 hours. His assistant, Ms. Nice, can grade the same exams in 15 hours. What fraction of the exams can Mr. Tough grade in 1 hour, without any help? This is impossible. Please help me. I spent sooo loong on this and got it wrong. I don't have many points. Sorry about the 20 points. IT IS VERY URGENT!!!!!!!!!!!!!!!!!

Answers

Answer:

1/12

Step-by-step explanation:

if Mr.Tough can grade 1 in 12 hours he can do 1/12

The fraction of the exams that Mr Tough and Mrs Nice grade in 1 hour if they work together is 3/20

What are fractions?

A fraction is used to denote a portion or component of a whole. Numerator and denominator are the two components that make up a fraction. There are three types of fractions: proper, incorrect, and mixed.

Using, rate × time = work done

So, Mr Tough's rate:

Mr Tough's rate × 12 hours = final exam

Mr Tough's rate = 1/12

and, Mrs. Nice's' rate:

Mrs .Nice's' rate × 15 hours = final exam

Mrs .Nice's' rate = 1/15

So, Total time:

T(1/12 hours + 1/15 hours) = final exam

T =  final exam / (1/12 + 1/15)

T =  final exam / (0.15)

Now, 1 hour =  final exam / (0.15)

final exam = 1 × 0.15

                = 0.15

                = 15/ 100

                = 3/20

Therefore, 3/20 fraction of the final exam.

Because you're asked to find the number so that x% is y, we will have to find that number. The equation in that case would be NUM * 0.934 = 107. Divide both sides by .934 to get an answer of approximately 114.56.

Show that 2/4-x = 10/4+x

is equivalent to 12x = 32 for all values of x not equal to 4 or -4

Answers

Answer:

See proof below

Step-by-step explanation:

Given the expression 2/4-x = 10/4+x

Cross multiply

10(4-x) = 2(4+x)

10(4) - 10x = 2(4)+ 2x

40 - 10x = 8 + 2x

-10x - 2x = 8 - 40

-12x = -32

Multiply both sides by -1

-1(-12x) = -1(-32)

12x = 32

This shows the required expression

Unbeknownst to them, James W. Marshall had discovered flakes of gold at Sutter's Mill near Coloma, California just days earlier. Marshall shared the news with John Sutter, the owner of the mill, and the two men decided to keep the discovery a secret. Unfortunately for them, news of the golden flakes spread. Sam Brannan even walked through San Francisco with gold, proving that there was indeed gold for the taking.When the news reached the East Coast, many American citizens were skeptical. When President James K. Polk shared a report written by Colonel Richard Mason, the military governor of California, the nation learned about the huge amounts of gold available. With this official confirmation, many men decided to sell their possessions, leave their families, and go west. They had gold fever and wanted to strike it rich. Most women did not go west. Instead, they remained at home to take care of businesses and farms. Many American prospectors chose to join the gold rush by sailing around Cape Horn or traveling overland along the Oregon-California Trail.Sailing Around Cape Horna map of the world with ships starting at the East Coast of the United States, traveling around South America, and ending on the West Coast of the Unites StatesMany people living on the East Coast chose to sail around the bottom tip of South America, past Cape Horn. Passengers purchased their fare for between 500 and 1000 dollars or more. The trip was long and could take five to seven months. Many passengers suffered from seasickness and boredom. Stormy weather sometimes sank ships. Cape Horn was infamous for its strong currents and unpredictable winds. Despite these dangers, over a third of fortune hunters chose to travel by ocean.Traveling Along the OregonCalifornia Traila map of the United States showing the Oregon Trail showing pioneers, a covered wagon, and a horse approaching the Rocky MountainsThose living in America's West chose to travel more than 2,000 miles overland along the Oregon-California Trail. For four to six months, oxen pulled the covered wagons filled with possessions along the bumpy trail. Prospectors walked beside the wagons or rode on horses. Wagons traveled together in groups called wagon trains. At night, the wagons made a circle to provide protection for the animals. Travelers cooked over fires and slept in the wagons or outside under the stars. These adventurers faced a lack of fresh drinking water, which led to outbreaks of cholera and typhoid. The journey to California led prospectors through formidable landscapes, including swift rivers, dusty plains, and dry deserts. Treacherous weather hit adventurers with lightning, hailstorms, and floods. Finally, as Native Americans watched an increasing number of people encroach upon their lands, they began to attack. However, these prospectors persevered and arrived in California.Regardless of their methods, over 300,000 adventurers joined the gold rush and arrived in California. Their contributions led to the creation of the state and shaped the city of San Francisco, which is built on abandoned gold rush ships.What were two ways that people reached California during the Gold Rush?
