HELP PLEASE!! 60POINTS - BRAINLIEST IF CORRECT

$20.52

Step-by-step explanation:

To find this, we have to first add up the prices of all the items.

5.25 + 2 x 3.18 + 2 x 1.29 + 4.99 = 19.18

So, without tax, we know that the total price is $19.18

Now, since the tax is 7%, that means the price with tax will be $19.18, plus the price of the tax.

To find the price of the tax, we just multiply 7% by 19.18.

7% can also be written as the decimal 0.07

0.07 x 19.18 = $1.34

Now, we just add 1.34 and 19.18

1.34 + 19.18 = $20.52

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
