The lower two larger spheres in the tower has a radius of 25 meters and 22.5 meters. Therefore, the total volume of the two largest sphere is as follows:

volume of lower sphere = 4 / 3 × 3.14 × 25³

volume of lower sphere = 196250 / 3

volume of lower sphere = 65416.6666667

volume of lower sphere = 65416.7 m³

volume of higher sphere = 4 / 3 × 3.14 × 22.5³

volume of higher sphere = 143066.25 / 3

volume of higher sphere = 47688.75

volume of higher sphere = 47688.8 m³

The approximate total volume = 65416.7 + 47688.8 = 113105.45 m³

James has a dog grooming service. He charges a flat rate of $50 per month, plus $10 per grooming. Bradly does not charge a month

solmaris [256]

Answer:

The numbers of grooming visits for which James and Bradly would charge the same amount is 2

Step-by-step explanation:

Let

w -----> the numbers of grooming visits

y ----> the charge in dollars

we know that

<em>James</em>

$y=10w+50$ ----> equation A

<em>Bradly</em>

$y=35w$ ----> equation B

equate equation A and equation B

$35w=10w+50$

Solve for w

$35w-10w=50$

$25w=50$

$w=2$

therefore

The numbers of grooming visits for which James and Bradly would charge the same amount is 2
