Joe is buying a jacket that originally costs $59.27 but is on sale for 10% off. Sales tax is 7%. What is the total cost of the j

postnew [5]

Hello!

10% off means there's a discount on the jacket, so we will be finding how much the discount is worth and then we'll subtract that from the original cost of the jacket.
Sales tax is basically additional money added to the cost of an item, so we will find what the sales tax is on this and then add that to the cost.

59.27 * 10% = 5.927

59.27 - 5.927 = 53.343

Now, find and add the sales tax.

53.343 * 7% = 3.73401

53.343 + 3.73401 = 57.07701

Round this to 57.1

The total cost of the jacket is $57.1.

A circular garden is enlarged so that the new diameter is twice the old diameter. What is the ratio of the original area to the

Amanda [17]

Answer:

Explained briefly below.

Step-by-step explanation:

For old circular garden:

take the radius as r.

then use the formula to find area of circle: πr² ......this is old garden area.

For new enlarged garden:

the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius

now find area for this new garden: π(2r)² → 4πr²

In common fractions: (old garden)/(new garden)

: ( πr² ) / ( 4πr² )

: 1/4
