Find the rate per hour for each of the four asked by diving the total by the number of hours:

Mark: 100 /10 = $10 per hour

Rick: 80 / 9 = $8.89 per hour

Steve: 75 / 8 = $9.38 per hour

Andy: 60 / 5 = $$12 per hour

Now add the four hourly rates and divde by 4:

10 + 8.89 + 9.38 + 12 = 40.27 / 4 = 10.07

Rounded to the nearest whole dollar would be $10 per hour.

The answer is A.

Triangle ABC has the following coordinates: A (-2, 3) B (4, -3) C (-2, -3) What are the coordinates points for triangle A'B'C' i

lina2011 [118]

Answer:

A' (3/2, -9/4)

B' (-3, 9/4)

C' (3/2, 9/4)

Step-by-step explanation:

1. You have the following coordinates of the vertices of the triangle ABC:

A (-2, 3) B (4, -3) C (-2, -3)

2. The given scale factor is -3/4, therefore, to calculate the coordinates of the triangle A'B'C', you must multiply each coordinate of the triangle ABC by the scale factor.

3. Therefore, you obtain that the the coordinates of the triangle A'B'C' are:

A'=((-2)(-3/4), (3)(-3/4))=(3/2, -9/4)

B'=(4(-3/4), (-3)(-3/4))=(-3, 9/4)

C'=((-2)(-3/4), (-3)(-3/4))=(3/2, 9/4)

X is directly proportional to w²

umka21 [38]

The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³

<h3>Variation</h3>

x = k × w²

w = 4, x = 48

48 = k × 4²

48 = k × 16

48 = 16k

k = 48/16

k = 3

So,

x = k × w²

x = 3 × w²

x = 3w²

y = k/x³

x = 2, y = 14

14 = k / 2³

14 × 2³ = k

14 × 8 = k

112 = k

So,

y = k/x³

y = 112/x³

y = (1/112)x³
