Answer:
the number of people as well as the number of chairs is 5.
Step-by-step explanation:

Answer:
A bus travels with a constant speed of 48 miles per hour. How long will it take to travel 60 miles?
Step-by-step explanation:
Mostly it's 1.25 hours </3 Since distance = rate times , or d = rt, then we have
t = d/r = 60 miles / 48 mph = 1.25 hours = 1 hour 15 minutes
either 1 hour 15 mins or 1hour and 25 mins.
Answer:
1.) 18 is decreasing by 83%
2.) 16 is decreasing by 12.5%
Step-by-step explanation:
Part ÷ Whole = Percent (decimal form)
1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being <em>decreased</em> by 83%.
2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being <em>decreased</em> by 2%.

Answer:
31
Step-by-step explanation:
V = (1/3)(b^2)(h)
<span>b = 48/4 = 12cm </span>
<span>h = 12cm </span>
<span>V = (1/3)(144)(12) = 576cm^3 (third choice) </span>
<span>3) </span>
<span>V = (pi)(r^2)(h) </span>
<span>V = (3.14)(64)(8) = 1608cm^3 (not one of the choices but I'm certain that this calculation is correct) </span>
