If the answer is D. the equation to represent the ages of students is:
n + n+1 + n+2 = 45
it is showing that n is the age of one student and the other student has age one year more than the first one and third students has age of 2 years more than first student and one year greater than the second student. if we solve this equation for the value of n, we get;
3n + 3 = 45
3n = 45 -3
3n = 42
n = 14
so the age of one student is 14, second student 15 and third student 16 years.
and if we add there ages, 14 + 15 + 16 = 45
Answer:
I think √170
Step-by-step explanation:
The points are A: (-3,5) and (4,-6) so we plug this into the distance formula
√(x2-x1)^2+(y2-y1)^2
√(4-(-3))^2+(-6-5)^2
√(7)^2+(-11)^2=
√49+121= √170 or a really long decimal which starts out 13.038404810
If I got the points wrong I can redo the problem and get another answer but I did the problem on my own and used a calculator and got the same answer
The volume of a sphere is
V_s = 4/3 * pi * r_s^3
The volume of a cone is
V_c = 1/3 * pi * h * r_c^2
Since we know that the two volumes are equal, we can say
V_s = V_c
4/3 * pi * r_s^3 = 1/3 * pi * h * r_c^2
Let us now isolate r_c, the radius of the cone:
4/3*r_s^3 = 1/3 *h*r_c^2
sqrt((4*r_s^3)/h) =r_c = 12 cm
So the radius of the cone is 12 cm
