Answer: 50
Step-by-step explanation:
Step 1: 60% = .60
Step 2: 30 = .60Y
Step 3: Divide both sides of the equation by .30 to isolate the variable Y.
30/.60 = .60/.60Y
50=Y
Therefore, 30 is 60% of 50.
Answer:
The side lengths cannot belong to a right triangle.
Step-by-step explanation:
This is a simple case of Pythagorean proof. If this triangle was a right triangle, 20^2 + 21^2 = 28^2. However, this is not the case. 20^2 + 21^2 = 841, which square root is 29.
If you forgot, the Pythagoren Theorem is: a^2 + b^2 = c^2.

i hope this helps
Answer:
- C=31.4cm , A=78.5cm²
- C=50.24mi. A=200.96mi.²
- C=25.12in. A=50.24in.²
- C=37.68Km A=113.04Km²
Step-by-step explanation:
C=2
x r
so for c you times 2
by your radius
Area is
times diameter (diameter is two times your radius)
