A plan traveled for a total of 2,773 miles over the course of 8 hours. Heading south, the plan traveled at an average speed of 3
AlexFokin [52]

Answer:

  5 hours

Step-by-step explanation:

Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...

  s + w = 8 . . . . . . total trip time

  344s + 351w = 2773 . . . . total mileage (using d = s·t)

By Cramer's rule, we can find the value of s as ...

  s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5

The plane was heading south for 5 hours.

_____

<em>Comment on Cramer's rule</em>

For the equations ...

  ax +by = c

  dx +ey = f

The solution for x can be found to be ...

  x = (bf-ec)/(bd-ea)

Similarly, the solution for y is ...

  y = (cd-fa)/(bd-ea)

three miners esch dup up 3 diamonds. the weight of the diamonds were 5,13,12,4,9,8,15,210, and 6 ounces of a piece. each of jack
Nataliya [291]

The total weight of Nico's diamond is 564 ounces

<h3>Weights</h3>

The weights of the diamond are given as:

5, 13, 12, 4, 9, 8, 15, 210, and 6 ounces

<h3>Total weights</h3>

Start by calculating the total weights

Total = 5+13+12+4+9+8+15+210+6

Total = 282

The above sum represents the total weights of Jack's diamonds.

So, the total weights of Nico's diamond is calculated as:

Nico = 2 \times 282

Nico = 564

Hence, the total weight of Nico's diamond is 564 ounces

What’s the points for the graph
Aleksandr-060686 [28]
The points for this graph are (3,0) and (0,2). Looking at the point to the right, you go left or right before you go up and down. You first go to the right 3 times, but you don't go up or down. So this point is (3,0). Looking at the next point you don't go left or right at all, but you do go up two spaces, so this point is (0,2).
