Wittaler [7]

Answer:

$18

Step-by-step explanation:

Given:

y = 0.9x - 4.5

Where,

x = age in years

y = hourly pay in dollars

what is the best prediction for the hourly pay of a 25 year old?

That is, find y when x=25

y = 0.9x - 4.5

= 0.9(25) - 4.5

= 22.5 - 4.5

= 18

y = $18

The prediction for the hourly pay of a 25 year old is $18

The diameter of a reamed hole is 70.36 mm. What is the radius setting, in mm., used to draw the hole?
Natalija [7]

Answer:

r = 35.18 mm

Step-by-step explanation:

We have,

The diameter of a reamed hole is 70.36 mm.

It is required to find the radius required to draw the hole.

The relation between diameter and radius is given by :

D = 2r

r is radius setting

r=\dfrac{D}{2}\\\\r=\dfrac{70.36 }{2}\\\\r=35.18\ mm

So, the radius setting used to draw the hole is 35.18 mm.
