Can you help me with this question please
1 answer:
Answer:
171 pounds
Step-by-step explanation:
So lets break this down
If the ratio between Ann and Bill is 2 : 9, then Bill gets 4.5 times more than Ann, because 9/2 = 4.5
We already know that Chloe and Dave get 2.5 times more than Ann
So let's first solve for how many pounds Ann gets, by this equation:
Where x is the amount that Ann gets
So lets solve:
So now we know that Ann gets 38 pounds, and Bill gets 4.5 times more than Ann, we we need to multiply 38 times 4.5., which equals 171 pounds

Answer:
<em>1885.5 m^3 of water</em>
<em></em>
Step-by-step explanation:
I'll assume this is the complete question
<em>Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14 </em>
<u><em>The pool forms</em></u><em> a cylinder with a radius of 12 feet and a height of 4.5 feet.</em>
<em></em>
height of pool = 4.5 ft
radius of pool = 12 ft
height of water is 4 inches below pool top
<em>12 inches make 1 ft</em>
4 inches = 4/12 ft = 0.33 ft
Therefore, height of water = 4.5 - 0.33 = 4.17 ft
<em>volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed</em>
volume of cylinder formed by the water = volume of water = πh
volume = 3.14 x x 4.17 = <em>1885.5 m^3 of water</em>
