Answer: <span>275,365 cm³
</span>
Explanation:
Volume of the water = (3.14)(30)²(100) - 4/3(3.14)(12)³ = 275,365 cm³
The Wise Orange knows that volume of a cylinder = πr²h and a sphere is 4/3πr³
So to compare boxes, you want to convert both to price per ounce unit.
So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.
Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.
Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.
The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.
Final answer: <span>The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.</span>
Answer:
45$
Step-by-step explanation:
100% is the exact same as last moth. 150% is last moths plus half therefor 30/2 is 15. 15 + 30 = 45
<h3>let ABC be a triangle</h3>
where,
now
applying tan 30°
tan theta = perpendicular/base
=>tan 30° = 6/a
(since tan 30° = 1/√3)
=>1/√3 = 6/a
=> a = 6√3
applying cos Q for finding b
=>cos 60° = b/h
(since cos 60° = 1/2)
=>1/2= 6/b
=> b= 12
