Answer:
23
Step-by-step explanation:
If cindy is 23 and marcus is 20 years older, 23+20= 43. Cindy is 23 and Marcus is 43, their ages added together is 66.
1 is D, an angle bisector only cuts the original angle in half.
2 is
9x - 18 = 3x
6x - 18 = 0
6x = 18
x = 3
3 is 9(3) - 18 = 27 - 18 = 9
17 by 17
Its all to do with square numbers so 17 x 17 = 289.
Just square root it and you get 17

Answer:
multiply the radius by √1.2 ≈ 1.0954
Step-by-step explanation:
Let the original depth and radius be represented by 30 and r. Let the modified depth and radius be represented by 25 and r'. Assuming the pond is uniform depth, the formula for the volume of a cylinder applies. The volume of a cylinder is given by ...
V = πr²h
In this application, we want the original and modified volumes to be the same.
πr²(30) = π(r')²(25)
(r')² = r²(30/25) = r²(6/5)
r' = r√(6/5)
The radius can be multiplied by √1.2 to maintain the original volume of the pond.
Answer:
4 because you divide 3 and 15 by three which gives you 5 then divide 20 by that gives you 4
