Answer:

4

Step-by-step explanation:

The total amount was $120.

A portion of the $120 was for parts.

The rest of the $120 was for service. Service cost $12 per hour.

Start with $120.

Subtract $72 to find the amount spent on service.

$120 - $72 = $48

$48 was spent on service.

The service costs $12 per hour.

$48/($12/hour) = 4 hours

Answer: 4 hours

Check:

$72 in parts + 4 hours * $12/hour = $72 + $48 = $120

4 hours is correct.

As the average daily temperature in New York City decreases, the number of persons who are observed wearing sweaters in the work
ruslelena [56]

When the average daily temperature in New York City decreases, the number of persons who are observed wearing sweaters in the workplace increases, this implies a<u> </u><u>negative correlation.</u>

Negative correlation simply means the relationship between two variables where as one variable increases, the other variable will reduce.

Therefore, in a situation where the average daily temperature in New York City decreases and the number of persons who are observed wearing sweaters in the workplace increases, this illustrates a negative correlation.

A factory ship the 100 boxes with 15 skateboards in each box and 10 boxes with 15 helmets in each box
netineya [11]

Answer:

150(10s + h)

Step-by-step explanation:

We need to write an expression for the total items they shipped.

Let each skateboard be s.

Let each helmets be h.

The factory ships 100 boxes with 15 skateboards in each box. That is:

100 * (15 * s) = 1500s

The factory ships 10 boxes with 15 helmets in each box. That is:

10 * (15 * h) = 150h

The total number of items shipped is therefore:

1500s + 150h = 150(10s + h)

This expression represents the total number of items shipped.

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)
