Answer:

147/4 or 36 3/4

Step-by-step explanation:

1 1/2=3/2

3 1/2=7/2

7/2 × 3/2 = 21/4

21/4 × 7 = 147/4

Step-by-step explanation:

1. 90+65= 155°

2. π+ π/6 = 7π/6 or 210°

3. 24+180=204°

4. 3π/2 + 2π/9 = (27π+4π)/18 = 31π/18

or 310°

Answer:

x=130°

y=50°

z=130°

Step-by-step explanation:

__________

Answer:

x = 130°

y = 50°

z = 130°

Step-by-step explanation:

From the diagram, you can see that the angle given, 50° is a vertical angle to y. This means they are equal, so y = 50°.

Next, angle x, and the given 50° angle are supplementary since they form a straight line. Because of this, you get that:

50° + x = 180°

- and -

x = 130°

You can see that angle z is a vertical angle to angle x, so they are equal, which gives you z = x = 130°. --> z = 130°

Imagine opening the Triangular prism

We will have 2 triangles at the base

and 3 rectangles

The sides of the triangle : base 9in, height 3in

Area of Triangle

   = [tex]\frac{1}{2} * base * height = \frac{1}{2} * 9*3 =\frac{27}{2}[/tex]

Now the rectangles

Rectangle1 with sides 9in and 15in, Area = 9*15 = 135

Rectangle 2 with sides 5in and 15in , Area = 5*15 = 75

Rectangle 3 with sides 6in and 15in, Area = 6*15 = 90

Now the total area of the prism

            = [tex]\frac{27}{2}+\frac{27}{2}+135+75+90 = 27+ 135+75+ 90 = 327in^{2}[/tex]

Answer:

28.26 ft.²

Step-by-step explanation:

Mathematics: Explain/formula.

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

[tex]\pi r^2(3.14*radius*radius)[/tex]

[tex]\pi =pi[/tex]

Mathematics: Solve.

Here, the diameter is 6 ft.

To find the radius, divide the diameter by 2.

[tex]6/2=3[/tex]

[tex]radius=3[/tex]

Now, we can plug the numbers into the formula.

[tex]\pi 3^2(3.14*3*3)=28.26[/tex]

Mathematics: Conclude.

Therefore, the area of this circle is 28.26 ft.²

the area of the given circle will be 28.27 ft².

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, a circle that has a diameter of 6 ft,

Since, Radius = diameter/2

Thus,

Radius = 6/ 2

Radius = 3ft

From the formula of the area of the circle:

Area = pi* radius *radius

In our case,

Area = pi * 3 * 3

Area = 28.274

Therefore, the area of the given circle will be 28.27 ft².

Answer:

The velocity at t = 6 is of -166 units of velocity.

Step-by-step explanation:

Velocity function:

The velocity function is the integral of the acceleration function.

We have that:

The acceleration function is:

[tex]a(t) = 12 - 4t^2[/tex]

So the velocity function is:

[tex]v(t) = \int a(t) dt = \int (12 - 4t^2) dt = 12t - \frac{4t^3}{3} + K[/tex]

In which K is the constant of integration, which is v(0).

v(0)=50

This means that:

[tex]v(t) = 12t - \frac{4t^3}{3} + 50[/tex]

What is the velocity at t=6?

[tex]v(6) = 12*6 - \frac{4*6^3}{3} + 50 = -166[/tex]

The velocity at t = 6 is of -166 units of velocity.

     AI: (b, z), (c, y); AE: (a, w), (d, x); SI: (b, y), (c, z); SE: (a, x), (d, w)

Step-by-step explanation:

This is a vocabulary question. It is intended to see if you understand the meaning of the names given to the different angle pairs in this geometry.

All of the pairs of angles filling the first 4 blanks (corresponding, vertical, alt. int., alt. ext.) are congruent pairs of angles. The pairs of angles filling the last two blanks (same-side ...) are supplementary angles (total 180°).

__

Corresponding angles lie in the same direction from the point of intersection. For example, the upper-left angles are corresponding.

Vertical angles are formed from opposite rays.

Alternate refers to angles on opposite sides of the transversal. (Same-side refers to angles on the same side of the transversal. Same-side angles are also called consecutive angles.)

Interior refers to angles that are between the parallel lines. Exterior refers to angles outside the parallel lines.

__

The figures are a bit fuzzy. We assume the angle designations are (CW around the intersection point from upper left, left group first) ...

  Figure 11) {a, b, c, d}, {4, 3, 2, 1}

  Figure 12) {d, c, b, a}, {z, w, x, y}

If this is not correct, you will need to make appropriate substitutions in the pairs given below.

__

11) Corresponding: (a, 4), (b, 3), (c, 2), (d, 1)

  Vertical: (a, c), (b, d), (4, 2), (3, 1)

  Alternate Interior: (c, 4), (d, 3)

  Alternate Exterior: (a, 2), (b, 1)

  Same-side Interior: (c, 3), (d, 4)

  Same-side Exterior: (a, 1), (b, 2)

Additional comment

The vocabulary is used to cite various theorems supporting claims regarding angle relationships. In practice, when the lines are parallel, all obtuse angles related to a transversal are congruent, all acute angles are congruent, and the acute angles are supplementary to the obtuse angles. (If the angles are 90°, neither acute nor obtuse, then they are all congruent.)

Answer:

[tex]68^\circ[/tex]

Step-by-step explanation:

FGD is congruent to CGE because they are vertical angles.

Because AB is a line and AGC makes a right angle, then CGB is also a right angle. Thus [tex]\angle{EGB} = \angle{CGB}-\angle{CGE}[/tex], or [tex]\angle{GCE} = 68^\circ[/tex]
