The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest wh
Misha Larkins [42]
Volume of a sphere with radius of 70 feet is:
V =  \frac{4}{3} * \pi * r^{3}

where r is that radius

Because we need quarter sized tank of that radius we need to divide formula for volume by 4

Than we get:
V =  \frac{1}{3} * \pi * r^{3}

V = 359188,76

Rounded:
V = 359189

What is the least common denominator of the fraction 3 x over x plus 1 plus the fraction x plus 1 over 2 x plus the fraction 5 o
Hoochie [10]
3x/(x+1) + (x+1)/(2x) + (5/x)

To find the least common denominator, we multiply the denominators that cannot factor into eachother. x, the denominator in 5/x, fits into 2x, so we do not need to multiply this number.
Therefore, the least common denominator is:
2x(x+1) 

The first term will be multiplied by 2x/2x
The second term will be multiplied by (x+1)/(x+1)
The third term will be multiplied by 2(x+1)

The box plots show the data distributions for the number of customers who used a coupon each hour for two days of a store sale.
lidiya [134]

Answer:

2

Step-by-step explanation:

We can observe from the box plot the medians of both days.

The line in the middle of the box plot represents the median.

The median for Day 1 is: 6

The median for Day 2 is: 8

We have to find the difference between medians of both box plots so the difference is:

8 - 6 = 2

The difference between the medians is 2 ..
