Answer:

B. 13

Step-by-step explanation:

Time taken to earn $385 = 35 hours

Time taken to earn $1 = \sf  \dfrac{35}{385} hours

\sf = \dfrac{1}{11} \ hours

Time taken to earn $143 = \sf  \dfrac{1}{11} \times 143 hours

\sf = 13 \ hours

35 divided by 385 is 11. This means Vivek will earn $143 in 11 hours.

Can you exchange the coordinates of points ( x 1, y 1) and ( x 2, y 2) in the distance formula and still find the correct distan
notka56 [123]

Answer:

yes

Step-by-step explanation:

As an example

(x₁, y₁ ) = (1,2) and (x₂, y₂ ) = (5,3), then

d = \sqrt{(5-1)^2+(3-2)^2} = \sqrt{4^2+1^2} = \sqrt{16+1} = \sqrt{17}

Now let (x₁, y₁ ) = (5,3) and (x₂, y₂ ) = (1,2), then

d = \sqrt{(1-5)^2+(2-3)^2} = \sqrt{(-4)^2+(-1)^2} = \sqrt{16+1} = \sqrt{17}
