For the full circle, Area = pi(r)^2
pi x 1^2 = pi
Semi circle = pi/2 = 1.57 square feet
1 and 7 because they have the same angles
1 1/2 * 3/4 =
Change 1 1/2 to an improper fraction = 3/2
3/2 * 3/4 = 6/4 * 3/4
6/4 * 3/4 = 18/4 = 4 2/4 = 4 1/2
The answer is 4 1/2.
Hope this helped☺☺
Answer:
Step-by-step explanation:
a) if the population at the beginning of the year 2000 was 7500 people,
The 1-year percent change in the city's population would be
3.6/100 × 7500 = 270
b) The population after 1 year is
7500 - 270 = 7230
The percentage of the previous value of the population to its new value for each year is
7230/7500 × 100 = 96.4%
c) the 1-year growth factor for the population of the city would be
(1 - 0.036)^1 = 0.964
d) the function, g that determines the population of the city (in thousands of people) in terms of the number of years t since the beginning of 2000 would be
g = 7500(1 - 0.036)^t
g = 7500(0.964)^t
Mark has 32 marbles and John has 96 marbles. If you add the marbles together they both have a total of 128.
