Is it accurate to call the 1920s the best of times

A carpenter purchased 70 ft of redwood and 80 ft of pine for a total cost of $351. A second purchase, at the same prices, includ

Hey there!!

Let us take the cost of 1 feet redwood as ' x '

Let us take the cost of 1 feet pine as ' y '

For the first scenario :

70 ft red wood and 80 ft pine

1 feet redwood - $x

70 feet redwood - $70x

1 feet pine - $y

80 feet pine - $80y

Total = $351

70x + 80y = 351 --------------------------------- ( 1 )

Second scenario :

1 feet redwood - $x

100 feet redwood - $100x

1 feet pine - $y

60 feet pine - $60y

total - $420

100x + 60y = 420 ----------------------- ( 2 )

Now let us get both the equations together :

70x + 80y = 351 ------------- ( 1 )

100x + 60y = 420 ------------- ( 2 )

Now let us multiply the the 1st equation with 3 and the 2nd equation with 4

3 ( 70x + 80y ) = 3 ( 351 )

4 ( 100x + 60y ) = 4 ( 420 )

............................

210x + 240y = 1053

400x + 240y = 1680

...........................

Now let us subtract the first equation from the second ...

400x + 240y = 1680

- ( 210x + 240y ) = - ( 1053 )

......................

190x = 627

dividing by 160 on both sides

x = 627 / 190

x = 3.3

The cost for 1 feet or per foot for the redwood is $3.3

Now substitute the value of x in any given given equation and find out y

I will substitute in the 1st equation

70x + 80y = 351

70 ( 3.3 ) + 80y = 351

231 + 80y = 351

Subtracting by 231 on both sides

80y = 351 - 231

80y = 120

dividing by 80 on both sides

y = 120 / 80

y = 1.5

The cost for 1 feet or per foot for the pine = $1.5

The answers - $3.3 ( redwood ) ; $1.5 ( pine )

Hope my answer helps!

What was the effect of the destruction of buffalo on native Americans?

pashok25 [27]

Years ago Native Americans discovered what they believed was a gold mine. They noticed a herd of 30 to 60 million Buffalo's roaming the plains. The Native Americans hunted the buffalo so they can maintain an accurate amount of food. By the 1700's the Native Americans tamed some of the buffalo, which made hunting easier. The Native Americans moved with the herds so they can have a good supply of food. The Native people used different methods of hunting. One method use is called the Dog Soldier. A group of Native people who are called this, push some of the herd over a cliff so some of the animals would die. During winter they would chance the larger animals onto frozen lakes and slaughter them. The ice made it difficult for the buffalo to run. Warriors did the killing. The woman were responsible for getting the meat. The rest of the buffalo was used for clothing, shelter and weapons. Native American knew that their survival depended on the buffalo. They never killed too many. They only killed wanted they needed and celebrated the life of the buffalo after.

TIMED! ESSAY: From 1855 to 1890, western settlement increasingly brought Americans and American Indians into conflict with one a

Rina8888 [55]

Answer:

Westward expansion beyond the American frontier was one of the most significant historical events in North American history. The United States quickly became one of the twentieth century’s most powerful nations after settling more than three million square miles of rich, diverse land. Despite the rewards, the expansion resulted in great destruction, suffering, and cultural loss to Native American peoples. Warfare between whites and Native Americans began as early as 1809 and ended in 1890, when the Indians were ultimately defeated and forced to live on reservations. Despite heavy military involvement in the Indian Wars, the final conquest of Native Americans rested squarely on the shoulders of the vast numbers of white settlers who wrested land from the native peoples. After 1800, the United States militantly expanded westward across the continent. Rooted in the idea of manifest destiny, the United States considered it a God-given right and duty to gain control of the continent and spread the benefits of its “superior” culture. Illustrated by the white, blonde, feminine figure of Columbia, the historical personification of the United States, people saw the nation’s mission as one of bringing education, modern technology, and civilization to the West and driving away the “uncivilized” American Indians.
