Since the equation for a circle is (x-h)^2+(y-h)^2=r^2, with the center being (h,k) and the radius being r, we can plug it in to get (x-(-2))^2+(y-3)^2=5^2
=(x+2)^2+(y-3)^2=25
Semester 1:
let the number of students in the art class be 2a, and the number of the students in the gym class be 7a. (check: the ratio is 2a:7a = 2:7)
so the total number of students is 9a.
semester 2:
the 9a students are go to the art class and gym class at a a ratio of 5: 4,
so 5a students go to the art class, and 4a students go to the gym class.
<span>75 students are in art class in second semester means that 5a=75,
so a=75/5=15.
In the 1st semester the number of students was:
art class: 2a=2*15=30
gym class: 7a=7*15=105</span>
No because
48 times 53=2544
his estimate is way off- it is off by (2544-250)= 2294
Answer:
704 pi in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi ( 8)^2 * 11
V = pi (704)
V = 704 pi in ^3
Answer: its 218
Step-by-step explanation: you just have to subtract 250 minus 32
