I have 2 questions to ask 1 is divide 180 degrees in a ratio of 4,5 and 9
MAXImum [283]

Here's how to do dividing in a certain ratio:

-- You want to divide up the whole thing in the ratio of
     4 parts, 5 parts, and 9 parts.

-- How many parts all together ?  (4 + 5 + 9) = 18 parts all together.

-- The whole thing is 180, and that's 18 total parts.
    So each part is  (180/18) = 10 degrees.

4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.

Check:  (40 + 50 + 90) = 180 .                yay!

==============================

For the second one, I think there are some words missing.

Two similar triangular prisms have volumes of 27 square meters and 64 square meters.
Inessa [10]

Answer:

9/16

Step-by-step explanation:

First we need to know that the dimensions ratio, the surface area ratio and the volume ratio have the following relation:

volume ratio = dimension ratio ^3

surface area ratio = dimension ratio ^2

The volume ratio between small prism and the large prism is 27 / 64.

To find the dimensions ratio, we need to take the cubic root of the volume scale:

dimension ratio = 3√(27/64) = 3/4

Now, to find the surface area ratio, we just need to make the square of the dimension ratio:

surface area ratio = (3/4)^2 = 9/16
