You need to change the denominators to the same number like 24 so then 3/8 = 9/24. 2/3 would be 16/24 and 1/3 would be 8/24 then you would add them up and simplify. 1 and 9/24 or 1 and 3/8

Answer:

I'm assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes

18+0.06m≥88.56

we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.

0.06m≥70.56

Then we dives by 0.06

m≥1176

Rania has used at least 1176 minutes

What is the surface area of this right circular cone?

docker41 [41]

Answer:

○ B) 624π mm.²

Step-by-step explanation:

$\pi r(r + \sqrt{ {r}^{2} + {h}^{2}}) = S. A. \\ \\ \pi (12)(12 + \sqrt{{12}^{2} + {40}^{2}}) \\ \\ 12\pi(12 + \sqrt{1744}) = 12\pi(12 + 38) = 12\pi(50) = 600\pi \\ \\ 600\pi ≈ 624\pi$
