What would a piece 430 feet 3 inches cost if you get a 10% discount for the larger volume? A piece of wire cable 180 ½ feet long
alexgriva [62]
To get the answer to this question you would have to multiply these numbers.
The normal price appears to be 65.95 for 180.5 feet. 
First we could divide 430.25 by 180.5
This divides out to become 2.39027778.
We would then multiply This by our normal price for 180.5 feet, which is 65.95.
This gives us 157.63882.
We would next need to take the 10 percent off. The easiest way to do this is to multiply our price by .90
This would give us 141.484938.

A TV has an original price of $599. Enter the new price after the given percent of change.
vlabodo [156]

Answer:

The new price = $718. 8

Step-by-step explanation:

Original Price =  $599

Given that the increase is 20%.

i.e.

Thus,

The amount of 20% Percentage increase = 20/100 × 599

                                                                             = 0.2 × 599

                                                                              = $119.8

Therefore,

New price = Original price + 20% increase amount

                 = 599 + 119.8

                  = $718. 8

Therefore, the new price = $718. 8

3xz(9xy+z)-2yz(x+y-z)
Alisiya [41]

Answer:  27x²yz + 3xz² - 2xy - 2y²z + 2yz²  

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

Use the distributive property.

   3xz(9xy + z)           - 2yz(x + y - z)

= 3xz(9xy)  +  3xz(z)  -2yz(x)   -2yz(y)   -2yz(-z)

=  27x²yz   +   3xz²    -2xy       -2y²z      +2yz²
