Answer:

Step-by-step explanation:

When looking at the number line, we can see the distance between A and B is one unit

A |-2| + |-1| = 2+1 =3 That is not 1 unit

B 2-1 =1 that is 1 unit

C -2 + -1 = -3 that is not 1 unit

D |-1| - (-2) = 1 + 2 =3 that is not 1 unit

Even though it says all expressions, there is only 1 that shows a distance of 1 unit

Answer:

$45

Step-by-step explanation:

Here we need to calculate the income of this year.

We know that a year has 52 weeks. And, our payed weeks are 51, they are, the 50 weeks we work plus the one week of paid-vacation. The remaining week does not give us income, as is unpaid. So our total year income is:

51 * $615 = $31,365

So, our surplus will be our income minus our expenses:

Surplus = $31,365 - $31,320 = $45

Our cash surplus is $45

nignag [31]

For this case we have the following conversions:
$1 mile = 1,609 km

1 mile = 5,280 feet$
We must apply the conversions to move from kilometers to feet.
We have then:
$(3.2) * (1 / 1,609) * (5280) = 10500.93226
$
Rounding off we have:
10501 feet
Answer:
there are 10501 feet in 3.2 km
