Answer:
53
Step-by-step explanation:
The area of the pool is ...
A = πr²
A = 3.14×(10 ft)² = 314 ft²
The number of bags of sand required is ...
(314 ft²)/(6 ft²/bag) ≈ 52.33 bags
53 bags of sand are needed.
Answer: 76.4
Step-by-step explanation:
Move the decimal over one
The answer is found by solving the unit rate and to find the unit rate we need to divide so 70/3 is 23.3333333 infinite now you can make it more simple by making it 23.34 and that means that the falcon travels 23.34 miles PER HOUR hope this helps
Answer:
-53/12
Step-by-step explanation:
Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then
![\frac{99}{2} (2x+98)=p^3 \\ \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}](https://tex.z-dn.net/?f=%20%5Cfrac%7B99%7D%7B2%7D%20%282x%2B98%29%3Dp%5E3%20%5C%5C%20%20%5C%5C%2099x%2B4%2C851%3Dp%5E3%5C%5C%20%5C%5C%20%5CRightarrow%20x%3D%5Cfrac%7Bp%5E3-4%2C851%7D%7B99%7D)
By substitution, we have that
![p=33](https://tex.z-dn.net/?f=p%3D33)
and
![x=314](https://tex.z-dn.net/?f=x%3D314)
.
Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>
