Answer: the number of hours of labor that was needed to complete the job is 11

Step-by-step explanation:

On the final bill, Samantha was charged a total of $1187. This means that the total amount that Samantha was charged was $1187.

$450 was listed for parts and the rest for labor. It means that the total amount charge for labour would be the total charge minus the amount charged for listed parts. Therefore,

Total labour charge = 1187 - 450 = $737

If the hourly rate for labor was $67, it means that the number of hours that the plumber worked would be

737/67 = 11 hours

a 32 foot ladder is leaned against a wall. if the base of the ladder is 8 feet from the wall, how high up the wall will the ladd
Leno4ka [110]

Answer:

31 feet

Step-by-step explanation:

Given: The length of ladder, leaned against wall= 32 foot

           The base of ladder is 8 feet away from wall

Adjacent= 8 feet and Hypotenuse= 32 foot

we need to find height of wall till the ladder reach (Opposite).

We will use Pythagorean theorem; hypotenuse^{2} = adjacent^{2} +opposite^{2}

⇒32^{2} = 8^{2} +opposite^{2}

⇒1024= 64+opposite^{2}

subtracting both side by 64

⇒ Opposite^{2} = 1024-64= 960

⇒Opposite= \sqrt{960} = 30.98 ≅ 31 ft

∴ 31 ft high up the wall.
