Answer:

48/37

Step-by-step explanation:

Use the formula (y1 - y2)/(x1 - x2).

Plug in your x and y values to get (92 + 4)/(81 - 7).

Simplify down to get 96/74 and simplify again to get 48/37.

Labor rate = $7.50 per hour Labor time = 6.5 hours Retail price of parts = $0 Total job cost = $82.00 Overhead rate?
Ulleksa [173]
Total cost job=
Retail price of parts+labor cost+manufacturing overhead

Total cost job 82

Retail price of parts 0

Labor cost=7.5×6.5=48.75

Manufacturing overhead ?

82=0+48.75+?

?=82−48.75

?=33.25

Manufacturing overhead is 33.25

Now find manufacturing overhead rate from the cost of labor
33.25÷48.75=0.682×100=68.2%

The answer 68.2%

Convert to the product of multiplication<br>a^2-b^2-4b-4
kirill [66]

a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .

<u>Step-by-step explanation:</u>

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , a^2-b^2-4b-4 :

⇒  a^2-b^2-4b-4

We know by identity that , p^2-q^2 = (p-q)(p+q)

⇒  (a-b)(a+b)-4b-4

Taking common term out as -4 :

⇒  (a-b)(a+b)-4(b+1)

Therefore  , a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .
