Answer:
0.341
or 1.0723
Step-by-step explanation:
the volume of hemisphere = (2/3)
r = (1/2)d = 0.8
(2/3)
= 0.341 = 1.0723
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Two secants drawn from outside the circle, then
The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) ← distribute both sides
9 + 3y = 2 × 11
9 + 3y = 22 ( subtract 9 from both sides )
3y = 13 ( divide booth sides by 3 )
y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
Answer: x ≥ -4 (in words: x is greater than or equal to -4)
Step-by-step explanation:
The number line shows all values greater than -4 being shaded in, meaning that x can be any of them. In addition, the point at -4 itself is shaded in, showing that it is also a possible value for x.
Answer:
46. 135°
47. 225°
47. 270°
48. 3/8
49. 3/4
Step-by-step explanation:
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish
