Answer:

$11.80 per hour

Step-by-step explanation:

So in the first 30 hours.Julio's rate is r ( the normal hourly rate)

so in the 35 hours we divide it as 30 hours and 5 hours as

30(r) + 5 (1.4r) = 436.60

solve for r : 30r + 7r = 436.60

                    37r=436.60

Divide both sides by 37 : r= 11.8

Julios normal hourly rate is $11.80 per hour

soldier1979 [14.2K]

Given :

Hight of the van from the ground, h = 3 feet.

The ramp into the van makes a 12° angle with the ground.

To Find :

How long is the ramp.

Solution :

Let, length of ramp is l .

So, height of ramp in terms of length is given by :

h = l \times sin\ 12^o\\\\l = \dfrac{h}{sin \ 12^o}\\\\l = \dfrac{3}{sin \ 12^o}\\\\l = 14.429 \ feet

Hence, this is the required solution.
