Answer:
40%
Step-by-step explanation:
decrease in price = 45 - 27 = 18
x% of 45 = 18
x= 40
Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
![A\text{ = }\pi rl](https://tex.z-dn.net/?f=A%5Ctext%7B%20%3D%20%7D%5Cpi%20rl)
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
![A\text{ = 2}\pi rh](https://tex.z-dn.net/?f=A%5Ctext%7B%20%3D%202%7D%5Cpi%20rh)
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
![\pi rl\text{ : 2}\pi rh](https://tex.z-dn.net/?f=%5Cpi%20rl%5Ctext%7B%20%3A%202%7D%5Cpi%20rh)
Canceling out, we have:
![\begin{gathered} =\frac{\pi rl}{2\pi rh} \\ =\text{ }\frac{l}{2h}\text{ or l:2h} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D%5Cfrac%7B%5Cpi%20rl%7D%7B2%5Cpi%20rh%7D%20%5C%5C%20%3D%5Ctext%7B%20%7D%5Cfrac%7Bl%7D%7B2h%7D%5Ctext%7B%20%20or%20l%3A2h%7D%20%5Cend%7Bgathered%7D)
Hence the Answer is option B
Answer:
320
Step-by-step explanation:
25 + 15 = 40 toys each
Toy makers x number of toys each = total toys carved
8 x 40 = 320 totals carved in all
It's quite simple. You just divide into the 3 sections. So, it is 36 divided by 12, which is 3. So A=3. :)
For this case, the first thing you should know is that a number in scientific notation is a number of the form:
![a * 10 ^ b](https://tex.z-dn.net/?f=a%20%2A%2010%20%5E%20b%20)
Where,
a: is a number between 1 and 10
b: is the exponent of the scientific notation.
We have then that the number that is in scientific notation written correctly is:
