Step-by-step explanation:
A = b x h
Answer:
1. 4/11 2. 2/10 or 1/5
Step-by-step explanation:
The first thing you need to do is find the total number of marble and then break it into their probabilities. 4+2+5= 11
Red: 4/11, Yellow: 2/11 and Blue: 5/11
So for 1. you just need the probability of pulling a red marble with we already figured out, 4/11.
For the second part you're looking for the probability of pulling a yellow marble after a red was pulled and not replaced. When we take one out and don't replace it the only thing that changes is the total and the number for that color so, the probabilities change to: Red: 3/10, Yellow: 2/10 and Blue: 5/10.
So now you have the probability of pulling a yellow if a red was pulled first without being replaced.
circumference = 3.14 * diameter
circumference = 3.14 * 4.79 ft
circumference = 15.0406 ft

Step-by-step explanation:
Unknown side length of two similar triangles can be found out by scale factor and any of the side lengths.
Step-by-step explanation:
The similarity is one of the criteria of triangles. Two triangles are similar when their respective sides are in similar ratio or proportion. In layman’s term, it can be understood as a condition in which two triangles have similar shapes but not similar sizes.
If ΔABC is similar toΔ XYZ, then their respective sides would be in proportion to each other.
This means AB/XY=AC/XZ=BC/YZ
This common ratio is often termed as “scale factor”
Hence any sides length can be found out if either of the terms (i.e. scale factor, side ) is given.
