Agold coin appreciated in value from $200.00 to $475.00 in 6 years. find the yearly rate of appreciation. show or explain all work.

16%

Step-by-step explanation:

To solve this we are using the standard growth equation:

Were

is the final value after years

is the initial value

is the growth factor (yearly rate of appreciation in our case) in decimal form

is the time in years

We know from our problem that gold coin appreciated in value from $200.00 to $475.00 in 6 years, so , , and .

Let's replace the values in our equation and solve for :

which rounds to

Since our appreciation rate is in decimal form, we need to multiply it by 100% to express it as percentage:

0.16*100% = 16%

We can conclude that the yearly appreciation rate of our gold coin is approximately 16%

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

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
