Answer:
4
Step-by-step explanation:
So you have 10 marbles all together. you remove one and dont replace it. it will be 3/9 which simplifies to 1/3.
To solve this problem you will need to use the cross product method:
1/16 of an hour → write 1 card
3/4 of an hour → write X cards
(3/4) ÷ (1/16) = X
0.75 ÷ 0.0625 = X
12 = X
Joey can write 12 Thank you cards in 3/4 of an hour.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
<u>The volume and the radius are given. (V=45π, r=3)</u>
<u>1. Solve for height</u>
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
<u>2. Plug the new radius (3*3=9) into this formula and solve for "V"</u>
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π
