Answer:

h=5in, r=1in

Step-by-step explanation:

The volume of a cylinder is:

V=\pi*r^2*h

where r is the radius and h is the height.

The height is 4 inches greater that the radius, so:

h=r+4in

Substituting this in the formula for volume:

V=\pi*r^2*(r+4)

the volume is V=5\pi in^3

thus:

5\pi in^3=\pi*r^2*(r+4in)

Dividing everything between pi:

5in^3=r^2*(r+4in)

5in^3=r^3*+4r^2

We can see that the solution for this is r=1in

since (1)^3*+4(1)^2=1+4=5

We have the radius, now we find the height:

h=r+4in=1in + 4in = 5in

h=5in, r=1in

Use trigonometry to solve for x. Round to the nearest tenth.
mel-nik [20]

Answer

12

Step-by-step explanation:

You need to use cosine because the side length needed is adjacent and you have the hypotenuse.Set up a proportion of "cos23 = x/13" and solve by cross multiplying. Then just round.

The sequence below represents Marisa’s fine at the library for each day that she has an overdue book:
Georgia [21]
The correct answer for the question that is being presented above is this one: "C. f(n) = 0.15n + 0.35." The equation that represents Marisa’s library fine as a function of a book that is n days overdue is f(n) = 0.15n + 0.35

Here are the following choices:
A. f(n) = 0.15n
<span>B. f(n) = 0.50n
</span><span>C. f(n) = 0.15n + 0.35
</span>D. f(n) = 0.50n + 0.15

Can you help me with number 3? Please!!!!
Fantom [35]

Answer:

D

Step-by-step explanation:

Take it step by step.

The area of a rectangle is width times length.

We know the length is 7 since it's given, and we can find the width by adding shared sides of the square and triangle.

So the width is 10 + 14 or 24

That means the area of the rectangle is 7 * 24

The area of the second rectangle is 12 * 14, since they are both given.

Finally, the area of the triangle is 1/2 of the base times height and we can find the height by looking at the shared side and using the definition of a rectangle.

So the area of the triangle is 1/2 of 10 * 12.
