We know the area of the middle rectangle is 48 (length * width). removing that rectangle leaves us with two semicircles. you can combine those semicircles to be the equivalent of one circle. the area for a circle is r^2 * pi. we know the diameter is 4 because that is where we cut the semicircles. radius is half the diameter, so r is 2. 2^2 is 4, 4* pi is 12.56. add 12.56 (area of semicircles) with 48 (area of rectangle) and we get 60.56
Answer:
75 students
Step-by-step explanation:
500 students x 0.25 (25%) = 125 play baseball
500 students x 0.10 (10%) = 50 play soccer
125 who play baseball - 50 who play soccer = 75 more students who play baseball
Answer:
Step-by-step explanation:
-4i+3i=i-8+3i-12
-i=4i-20
20=4i+i
20=5i
20/5=i
4=i
Answer:
98 cats and 19 dogs
Step-by-step explanation:
cat = c
dog = d
The animal shelter currently has a total of 117 animals
c + d = 117
c = 117 - d
the number of cats is 3 more than 5 times the number of dogs
c = 3 + 5d
subtitute c
117 - d = 3 + 5d
117 - 3 = 5d + d
114 = 6d
6d = 114
d = 114/6 = 19
so, the cat is 117-19 = 98
