1. Simplify the expression.
29m - 15
_______
25
2. 11 (5x + y)
________
35
Step-by-step explanation:
Firstly triangle OAB is equilateral so R = AB =OA = 8 in
MES (ARC AB) = R x Ф (in Radian). Note that 60° =π/3
MES (ARC AB) = 8 x π/3 (D)
His mom paid 30 and he paid 10 I did 40÷4 the got 10 then times by how many 25% each had
The volume of a sphere = 4πr^3/3<span>
The volume of a half of sphere = 2</span>πr^3/3 = 2 π (27)/3 = 18π<span>
</span>The volume of a cone= π r^2 h/3 = π (9)(8)/ 3 = 24 π
Total volume = 18 π + 24π = 42π = 42 x 3.14 = 131.9 cm^3
