Step-by-step explanation:

I am not positive if the experimental probability questions are correct, since it has been a while since I've done this, but the theoretical questions should be right. This is because there are 4 kings in every deck and there is replacement. Also, there are 13 hearts in each deck and there is replacement.

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?

Answers

Given:
radius of the cone = half the radius of the cylinder
height of the cone = radius of the cylinder

Volume of the cone = π r² h/3

let x be the radius of the cylinder

V = 3.14 * (x/2)² * x/3
V = 3.14 * (x/2 * x/2) * x/3
V = 3.14 * x²/4 * x/3
V = 3.14x³ / 12
The answer is π r³/12.

The radius of the cylinder is r.
The radius of the cone is half of the radius of the cylinder: r/2.
The height of the cone is equal to the radius of the cylinder: r.

If the volume of the cone is 
π r²h/3, and the radius of the cone is r/2, and the height of the cone is r, then:
V = π × r² × h / 3
V = π × (r/2)² × r / 3
V = π × r²/4 × r / 3
V = 
π r³/12

For which equation is x = 6 the solution?2x = 8
6x = 66
8x = 56
9x = 54

Answers

Just insert 6 into x then multiple it out and see if it matches right side of the equation.

The answer is D, 9x = 54, since 9×6 = 54.

Answer:

D 9x=54

Step-by-step explanation:

just look at it as 9times6=54 .

What is 0.96 recurring as a fraction

Answers

Answer:

96/100

Step-by-step explanation:

Numerator & Denominator for 0.96 as a Fraction

0.96 = 0 96/100

numerator/denominator = 96/100

Level of Precision for 0.96 = 0 96/100

Customize the level of precision to break 0.96 down further into a fraction. Note that the last digit after the precision point is rounded up or down accordingly.

With that in mind decimal 0.96 with a precision point of two has the following fractional breakdown:

96/100

= 48/50

= 24/25
