what is the sum of the interior angles of a heptagon ?

Answers

Answer 1

Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.

Number of sides in a heptagon = 7

So, n = 7

So,

the sum of the interior angles of a heptagon

= (7 - 2) × 180°

= 5 × 180°

= 900°

Answer 2

Answer:

900

C) the triangles are congruent

Step-by-step explanation:

Answer:

c. the triangles are congruent

Step-by-step explanation:

Both the triangles are right triangles which means the square thing at the bottom corner of the triangles are 90 degrees. So with this info, a triangle is 180 degrees, and one of the triangles already gave u one of the corners degrees so

90 + 59 + x =180

149 + x = 180

x = 31, so now the left triangle is solved. Now see the 118 degrees in the middle? A straight line is 180 degrees so with this in mind,

31 + 118 + x = 180

149 + x = 180

x = 31

The right triangle also has 31 and 90 as two of its angles, we don't need to calculate to know the last angle left is 59 like the left triangle. Therefore both triangles are congruent as they are the same.

I need to know which ones are nonlinear or nonproportion

Answers

Nonlinear means that -- the graph isn't exactly the line. It's basically a "curve" like parabola.

Non-proportional means that --- the graph doesn't start from the origin point or doesn't start at (0,0).

( A ) is both linear and proportion.

( B ) is proportion BUT NOT LINEAR (It's curved.)

( C ) is linear and proportion.

( D ) Is linear BUT NOT PROPORTION (Doesn't start at (0,0) )

So ( B ) and ( D )

A gum ball has a radius that is 30mm. The radius of the gumballs spherical hollow core is 28mm. What is the volume of the gum ball if you do not include it's hollow core

Answers

Answer:

V = 21145.01 mm³

Step-by-step explanation:

Given that:

The radius of the gumball = 30  mm

The radius of the spherical hollow-core = 28 mm

Consider the radius of the gumball to be [tex]r_2[/tex] and the radius of the spherical hollow-core to be [tex]r_1[/tex]. Then;

The volume of the gumball can be determined by using the formula of a sphere.

[tex]V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)[/tex]

[tex]V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)[/tex]

V = 21145.01 mm³

Answers

Answer:

i need this asap

Step-by-step explanation:

The equation that models the situation; [tex]y = 148.4 \sqrt {x-1} +154[/tex] Thus, option B is correct.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A company manufactures acoustic guitars.

The table shows the number of units that the company sold each month over a nine-month period beginning in January, that is;

Month, x 1 2 3 4 5 6 7 8 9

Units, y 150 300 380 425 425 480 520 550 575

If we put x = 2

[tex]y = 148.4 \sqrt {2-1} +154\\\\y = 148.4 +154 = 302.4[/tex]

Y = 300 ( approx)

We can see that the equation that models the situation;

[tex]y = 148.4 \sqrt {x-1} +154[/tex]

Thus, option B is correct.
