Answer:

47.1

Step-by-step explanation:

Sorry if its wrong

The cone's volume is approximately 47.1 cubic centimeters, obtained by rotating the provided isosceles triangle along its central blue axis.

The volume of a cone is calculated by the following formula:

[tex]$V = \frac{1}{3}\pi r^2 h$[/tex]

where r is the radius of the base and h is the height of the cone.

In this case, the height is simply the height of the triangle, which is 5 cm.

The radius is a bit trickier.  

Notice that the blue dashed line bisects the base of the triangle.  Therefore, the radius is half the length of the base, which is 6 cm / 2 = 3 cm.

Substituting these values into the formula, we get:

[tex]$V = \frac{1}{3}\pi (3\text{ cm})^2 (5\text{ cm})$[/tex]

[tex]$V = 15\pi \text{ cm}^3$[/tex]

Rounding this to the nearest tenth, we get:

[tex]$V = 47.1 \text{ cm}^3$[/tex]

Therefore, the volume of the cone is approximately 47.1 cubic centimeters.

-4b + 18 = -6

Subtract 18 from both sides:

-4b + 18-18=-6-18

Simplify:

-4b= -24

Divide both sides by -4:

-4b/-4 = -24/-4

Simplify:

b=6

Your Answer Is b= 6

Answer:

105 degrees

Step-by-step explanation:

The sum of the angles in a triangle add up to 180. Although we don't the know the numerical values of the angles, we can create an equation with the given expressions:

<P + <Q + <R = 180

(6x + 5) + (11x - 5) + x = 180

18x = 180

x = 10

Now, plug this value of x into the expression for Q:

<Q = 11x - 5 = 11 * 10 - 5 = 110 - 5 = 105

Thus, the measure of angle Q is 105 degrees.

Hope this helps!

Answer:

105 degrees

Step-by-step explanation:

The angles in a triangle must add to 180 degrees

<Q +<P + <R =180

We know <Q is 11x-5, <P is 6x+5 and <R is x, so we can substitute them in

11x-5+6x+5+x=180

Combine like terms

11x+6x+x +5 -5 =180

18x=180

Divide both sides by 18

x=10

Now we know x, and we can substitute that in to to find <Q

<Q=11x-5

<Q=11(10)-5

<Q=110-5

<Q=105

Answer: B

Step-by-step explanation:

X axis only

The graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only

In mathematics, symmetry has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.

A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related.

Here,

The graph of r = -3 + 5cosθ is symmetric about the x axis only

Also when we plot the graph we can say that it is symmetric about x axis only.

Hence, the graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only

But for the second expression, the answers are not equivalent

Answer:

If both expressions have the same value after substituting and simplifying for x = 6 and x = 2, then they are equivalent. The value of both expressions is 15 when x = 6. The value of both expressions is 7 when x = 2. So, the expressions are equivalent

Answer:

Step-by-step explanation:

XY=ST/2

3z+2=(7z-1)/2

2*(3z+2)=7z-1

2*3z+2*2=7z-1

6z+4=7z-1

+1         +1

6z+5=7z

-6z      -6z

5=z

The required value of z is 5.

Given that,

In RST, X is the midpoint of RS,

And Y is the midpoint of RT.

XY = 3z + 2 and ST = 7z - 1.

We have to determine,

What is the value of z.

According to the question,

X is the midpoint of RS,

And Y is the midpoint of RT.

Therefore,

[tex]XY = \frac{ST}{2}[/tex]

Putting the value of XY and ST in the equation,

XY = 3z + 2 and ST = 7z - 1.

Then,

[tex]XY = \frac{RS}{2} \\\\3z+ 2 = \frac{7z-1}{2}\\\\2 \times(3z+2) = 7z-1\\\\= 6z+4= 7z-1\\\\6z-7z = -1-4\\\\-z = -5\\\\= z = 5[/tex]

Hence, The required value of z is 5.

Answer:

A) 288 [tex]cm^{3\\}[/tex]

Step-by-step explanation:

The Volume of the figure is 288 cm³.

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

Given:

Base edges = 4 cm x 4 cm

Height = 1 cm

So, Volume = area of the base x height

For Figure 1:

Volume of figure1

=(4x4)x 10

=160

For Figure 2:

Volume of figure 2

Answer:

37 Degrees

Step-by-step explanation:

Manipulate the triangle so angle A measures approximately 92°.

Manipulate the triangle so angle B measures approximately 51°.

Notice the straight line p.

What must the measurement of angle C be for p to remain a straight line?

Angle C should measure approximately 37 Degrees

There is angle C should measure approximately 37° for line p to remain a straight line.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As we know that a straight line, the sum of the angles is equal to 180°.

So, when angle A measures approximately 92° and angle B measures approximately 51°,

Then, the measurement of angle C must be 180° - 92° - 51° = 37° in order to keep line p a straight line.

Thus, angle C should measure approximately 37° for line p to remain a straight line.
