Answer:

D. $53.76

Step-by-step explanation:

When calculating discounts and sales tax, you need to first change your percentages to decimals by dividing each by 100:

20%/100 = 0.2

5%/100 = 0.05

Since the shoes are at a 20% discount, you will only pay 80% of the original amount, or:  $64.00 x 0.8 = $51.20

However, you also need to pay a 5% sales tax, in addition to the sales price, so you can take the discounted amount and multiply:

$51.20 x 1.05 = $53.76 total cost

An equation parallel and perpendicular to 4x+5y=19
mestny [16]

Answer:

An equation parallel to 4x + 5y = 19 would be y = -4/5x +12.

An equation perpendicular to 4x + 5y = 19 would be y = 5/4x + 10.

Step-by-step explanation:

The equation given represents a linear equation in Standard Form (Ax + By = C).  Lines that are parallel to each other go the same direction and don't touch, so their slopes must be the same.  However, lines that are perpendicular go in opposite directions and intersect, so their slopes must be the direct opposite of each other.  In order to find the slope, you must first convert from the Standard Form given to Slope Intercept Form (y = mx +b).  When you solve the given equation for 'y', you get: y = -4/5x + 19, where the slope = -4/5.  To make a parallel equation, simply keep the same slope and choose a different y-intercept ('b').  To make a perpendicular equation, take the direct opposide of your slope 5/4 (positive) and choose a different y-intercept.

Solve the equation by finding the square roots<br>w^2-36=-64​
sammy [17]

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : w^2-36-(-64)=0 Step by step solution : Step 1 : Polynomial Roots Calculator : 1.1 Find roots (zeroes) of : F(w) = w 2 +28 so the answer could be 2.176 or 30.

Total revenue is 3,000 cost of goods 1,500 total selling expence is 500 what is profit
12345 [234]
Cost of goods = 1,500
Selling expense = 500

Total cost in selling = 1500 + 500 = 2000

Profit = Total Revenue - Total cost in selling = 3000 - 2000 = 1000

Profit = 1000

Hope this explains it.
