A DVD movie sells for $25 and the sales tax is 6.5%. What is the total cost of the movie to the nearest penny

1 answer:

6 0

Hello! First, let's add 1 to the tax rate in decimal form. 6.5% is 0.065. 1 + 0.065 is 1.065. Multiply that number by 25 to get 26.625 or 26.63 when rounded to the nearest penny. The total cost of the movie is $26.63.

Note: If a question asks for the total cost with tax, always add 1 to the tax rate in decimal form. That way, you will get straight to the answer and not have to do any complicating work.

Patricia purchased x meters of fencing. She originally intended to use all of the fencing to enclose a square region, but later

Answer:

(y^2)/4 square meters

Step-by-step explanation:

For a perimeter length of x, the side of a square will be x/4 and its area will be (x/4)^2.

If one side of the square is shortened by y/2 and the adjacent side is lengthened by y/2, then the difference in side lengths will be y. The area of the resulting rectangle will be ...

(x/4 -y/2)(x/4 +y/2) = (x/4)^2 -(y/2)^2

That is, the difference in area between the square and the rectangle is ...

(x/4)^2 - ((x/4)^2 -(y/2)^2) = (y/2)^2 = y^2/4

The positive difference between the area of the square region and the area of the rectangular region is y^2/4 square meters.

Jayson’s car can go 300 miles on 12.5 gallons of gasoline. How far can he drive on 42 gallons of gas?

fomenos

$300\ miles\ on\ 12,5\ gallons\\
x\ miles\ \ on\ \ \ 42\ gallons\\\\
Making\ proportion:\\
300-12,5\\
x-42\\\\
Cross\ multiplication\\
300*42=12,5x\\\\12600=12,5x\ \ \ | divide\ by\ 12,5\\\\
x=1008\\\\
He\ can\ drive\ 1008\ miles\ on\ 42 \ gallons\ of\ gas.$
