Answer:
24 purple jelly beans
Step-by-step explanation:
We are told in the question that;
Lucas had a mix of red and purple jelly beans. There were 2 red jelly beans for every 3 purple jelly beans.
The results in a ratio
2:3
Where 2 represented red jelly beans
3 represented purple jelly beans
Total number of jelly beans = 40 jelly beans.
The number of purple jelly beans that we have =
3/( 2 + 3) × 40
= 3/5 × 40
= 3 × 8
= 24.
Hence, there are 24 purple jelly beans in the bag.
Answer:
I'm not the greatest at math but I'll see if I can get this right.

Answer:
Step-by-step explanation:
You should set this up as an y = mx + b equation. Since 300 is her final number, that will be your y value. She started with 100, so that will be your b value. 20 is the number related to the variable you don't know so that will be your m.
300 = 20x + 100
-100 -100
200 = 20x
divide both sides by 20
10 = x
Answer with Step-by-step explanation:
V=kr²h
Where r is the radius and h is the height of the cylinder
Cylinder A has a volume of 251.2 cubic inches and has a radius of 4 inches and a height of 5 inches.
⇒ 251.2=k×4²×5
⇒ 251.2=80k
⇒k=251.2/80
⇒ k=3.14
We have to find volume of cylinder B, which has a radius of 3 inches and a height of 9 inches
r=3 inches
h=9 inches
V=3.14×3²×9
=254.34 cubic inches
Hence, Volume of cylinder B is:
254.34 cubic inches
