John received $300 for his birthday he buys 4 DVDs at $12.95 each. Sales tax is 6.5% how much birthday money does he have left
joja [24]

Answer: $244.83


Step-by-step explanation:

First find the original amount spent on dvds:

    $12.95 * 4 = $51.80

Then, the sales tax (6.5% is converted to decimal form by dividing by 100):

    $51.80 * 0.065 = $3.367

Add the sales tax to the original amount to get the total amount spent:

    $51.80 + $3.367 = $55.167

Round to the nearest hundredth:

    $55.167 -> $55.17

Subtract the total amount from the money received for his birthday:

    $300 - $55.17 = $244.83

Triangle ABCis rotated 90° clockwise around the origin to get
Elanso [62]

Answer:

The distance A’C’ is 4.47 units

Step-by-step explanation:

Before we go on, we need to get the appropriate transformation

Mathematically, we have a 90 degrees clockwise rotation yielding the following;

(x,y) to (-y,x)

A is (-4,1)

C is (-2,5)

By transforming, we have

A’( -1,-4)

C’ (-5,-2)

To get the magnitude of the line segment, we are going to use the distance formula between points

We have this as;

D = √(x2-x1)^2 + (y2-y1)^2

D = √(-5-(-1))^2 + (-2-(-4))^2

D = √(-4)^2 + (2)^2

D = √(16 + 4)

D = √20

D = 4.47 units
