Answer:
500 /3 pi cm^3
Step-by-step explanation:
The side length of the cube is 10 cm, so the diameter of the sphere is 10 cm
That means the radius is
r =d/2 =10/2 = 5 cm
The volume of a sphere is
V = 4/3 pi r^3
= 4/3 pi (5)^3
= 500 /3 pi cm^3
I got E and F. A would be correct as is I think, B is 9^2x, C, correct as is, D, is 9 ^2x, and E and F is 9^x
<h3>The system of equations has infinitely many solutions</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
y = x + 2 ------ eqn 1
-3x + 3y = 6 -------- eqn 2
Solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
-3x + 3(x + 2) = 6
-3x + 3x + 6 = 6
-3x + 3x = 6 - 6
0 = 0
If we end up with the same term on both sides of the equal sign, then we have infinite solutions
Thus the system of equations has infinitely many solutions
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = 
sin(15.5°) = 
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.
