Given the graph below, which of the answer choices is closest to the actual distance between point A and point C?
65
33
the square root of 65
the square root of 33

Answers

Answer:

[tex]\sqrt{65}[/tex]

Step-by-step explanation:

d = √(5+2)²+(0+4)²

d = √7² + 4²

d = √49+16

d = √65

Answer:

square root of 65

Step-by-step explanation:

So remember, the pythagreons theorm is A^2+B^2=C^2.

A and B are the side lengths, and C is the long, sloped line.

Lets count the side lengths, and plug them into the formula.

Line CB is 4, and counting AB, its 7. So lets plug them in:

4^2+7^2=C^2

Square the values(except for the missing one):

16+49=C^2

65=c^2

Now, we need to get C on its own.

To do this, we must get the square root of both sides:

[tex]\sqrt{65} =\sqrt{C^2}[/tex]

[tex]\sqrt{65} =C[/tex]

So C equals the square root of 65!

This is C, the third answer down(the square root of 65).

Hope this helps! :)

Answer:

The point slightly past 200.

Step-by-step explanation:

The volume of a cylinder is given by [tex]V=r^2\pi\cdot h[/tex].

Using 3.14 for [tex]\pi[/tex] as requested in the problem, we have:

[tex]V=4^2\cdot3.14\cdot 4=\boxed{200.96}[/tex].

Therefore, the correct point should be slightly past 200.

Answer:

Second red point from the right. The one above 200.

Step-by-step explanation:

V = πr²h

V = (3.14)(4 in.)²(4 in.)

V = 200.96 in.³

A 12-ft ladder is leaning on a building. If the base of the ladder is placed 5 feet from the building, approximately how high does the ladder reach?

A. 13 ft
B. 7 ft
C. 11 ft

b=10.9

The answer is c.

The answer is C using the Pythagorean theorem, A^2 + B^2 equals C^2.

Here is the question!: Find the surface area of the following triangular prism.

Answers

Answer:

[tex]336\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The total surface area simply consists of three rectangles and two triangles. To find the total surface of the figure, find the sum of each of the shapes that make up the outside of the figure:

2 triangles: 2 x 1/2 x 6 x 8 = 48 ft^2

First rectangle: 6 x 12 = 72 ft^2

Second rectangle: 8 x 12 = 96 ft^2

Third rectangle: 10 x 12 = 120 ft^2

*Note: One of the dimensions is in yards, so make sure to convert it to ft (1 yd = 3ft)

Thus, the total surface area of the figure is 48+72+96+120 = 336 ft^2.

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.
