Answer:
290 units long.
Step-by-step explanation:
This is a 3D version of the pythagorean theorem.
2D c = sqrt(a^2+b^2) or c^2 = b^2 + a^2
3D bar length = sqrt(FG^2 + BC^2 + FC^2)
so: sqrt(16^2 + 288 + 30^2) = 290
Have a good day.
Answer:
Colin gets
of the total money
Step-by-step explanation:
If we let the total amount be "90" (or any multiple of 9), then the solution gets much easy.
Let total money be 90.
Caroline gets 1/9, so that is:
1/9 * 90 = 10
Remaining is 90 - 10 = 80
This 80 is divided in the ratio 1:3, that means Colin gets 1 part and Sarah gets 3 part. That is 1 + 3 = 4 parts altogether.
80 divided in 4 parts is 80/4 = 20 each part.
Colin gets 1 part, that is 1 * 20 = 20
Colin gets 20 OUT OF 90 (total initial).
<em>What proportion is that? We simply divide and reduce!!</em>

20/90 = 2/9

Answer:
its 53
Step-by-step explanation:
5. if x=3 then replace x with 3. 3^2 is 9, 1/3 of 9 is 3, 3+2 = 5
