For this case, we must indicate what was the final cost of the items since the TV has a 20% discount. So, we make a rule of three to determine the discount amount.

545 ---------------> 100%

x -------------------> 20%

Where "x" represents the amount given by the 20% discount.

x = \frac {20 * 545} {100}\\x = 109\

So, on TV you save $ 109.

545-109 = 436\

Payment for TV $ 436

Then the total cost of the two items, excluding taxes, was:

185 + 436 = 625\

Answer:

$ 625

$185 + $545 = $730
$730 x .20 = $146
$730 - $146 = $584

FINAL COST NOT INCLUDING TAX:
$584

In the equation y = kx, the slope of the line is represented by the constant
vovangra [49]
K is the constant of proportionality also the same as slope.
You can see the commonality in the equations
y = kx
y = mx + b
The difference is that is a direct proportion the line will always go through the origin so the b will be zero.
The answer is B.

Can anyone help me out? thanks
Alik [6]

Answer:

450 cm

Step-by-step explanation:

12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.

The minor arc length of 15 is in the same ratio to the circumference as  the 2 angles , so the circumference = 30 * 15 - 450 cm.
