Answer:

4,140 degrees

Step-by-step explanation:

Mathematically, the sum of interior angles of a polygon is;

(n-2)180

where n is the number of sides the polygon has

Mathematically;

we will be replacing n by 25 here

So, we have;

(25-2)180

= 23 * 180 = 4,140 degrees

Given:

The base of a prism is a right triangle with legs measuring 16 feet and 4 feet.

Height of the prism is 14 feet.

To find:

The volume of the triangular prism.

Solution:

The area of a triangle is:

[tex]Area=\dfrac{1}{2}\times b\times h[/tex]

Where, b is base and h is height of the triangle.

The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. It means the base of the triangle is 16 feet and height is 4 feet. So, the area of the base of the prism is:

[tex]B=\dfrac{1}{2}\times 16\times 4[/tex]

[tex]B=32[/tex]

Now, the volume of a triangular prism is:

[tex]V=Bh[/tex]

Where, B is base area and h is the height.

Putting [tex]B=32,h=14[/tex] in the above formula, we get

[tex]V=32\times 14[/tex]

[tex]V=448[/tex]

Therefore, the volume of the triangular prism is 448 cubic feet.

Answer:

  B, C, E

Step-by-step explanation:

When the central angles are congruent, the corresponding triangles are congruent:

  ΔJHK ≅ ΔLHM . . . . selection E

and the base chords are congruent:

  ML ≅ JK . . . . selection B

The subtended arcs are also congruent, so adding arc LK to each will result in congruent arc measures:

  arc MLK ≅ arc LKJ . . . . selection C

Answer: BC = 5.83

Step-by-step explanation:

Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:

AB = 5

AC = 3

BC = ?

To find BC, we can simply use the Pythagorean Theorem:

[tex]a^{2}+b^{2}=c^{2}[/tex]

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

Now square root to find c, or BC.

[tex]\sqrt{34}=\sqrt{c^{2} }[/tex]

c = 5.83 (rounded by nearest hundredth)

Answer:

D

Step-by-step explanation:

Answer:

x = 22

Step-by-step explanation:

The sum of the angles round a point is 360°

Sum the given angles and equate to 360

x + 6x + 40 + 3x + 100 = 360

10x + 140 = 360 ( subtract 140 from both sides )

10x = 220 ( divide both sides by 10 )

x = 22

Answer:

D. inverse variation; xy = 8

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

For direct variation the equation relating x and y is

y = kx, that is

k =  

Using the values in the table

= 2

=  

k is not constant hence not direct variation

For inverse variation the equation relating x and y is

y = , that is

k = xy

Using the values in the table

2 × 4 = 8

4 × 2 = 8

8 × 1 = 8

12 ×  = 8

Thus the table represents inverse variation with xy = 8

...............................................................................................................................................

Answer:

D. inverse variation; xy = 8​

Step-by-step explanation:

First we need to understand the concept of direct and inverse relation or proportion between variables.

When value of one variable increases with the increase in value of second variable, this relation is called directly proportional.

When value of one variable decreases with the increase in value of second variable, this relation is called inverse proportion.

You can observe it it daily life example too. Like if you pour water in glass, its weight will increase. If you add more water, the weight of glass will increase more. It is direct proportion. But on the other hand, if one man do any particular task in 2 hours, two men will perform task in less time, which means the hours of work are inversely proportional to number of men.

Now in given equation you can see that, when x = 2, y =4, but when x = 4, y =2, which means value of y is decreasing with the increase in value of x. So this relation is inverse.

You can also satisfy the equation by putting values of x and y.

xy = 8

From first column

2x4 = 8

Therefore...

A:

12 foot = 365.76

365.76 / 45.72 = 8

Answer:

y=3,000(0.985)^x

y=1,500(1.012)^x

Step-by-step explanation:

System of equations  Brandon can use for  two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]

Profit and loss percentage are used to refer to the amount of profit or loss that has been incurred in terms of percentage.

According to question

Brandon is analyzing the profits from two of his restaurant locations.

where

x = number of week

y = the profit

1st restaurant : showed a profit of $3,000 in the first week of the year but

has a showed a steady decrease in profits of 1.5% each week since then

So in equation we can write it as

y= [tex]3000(1 - 0.015)^{x\\}[/tex]

y= 3000[tex](0.985)^{x}[/tex]

2nd restaurant : showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since then.

So in equation we can write it as

y = [tex]1500(1+0.012)^{x}[/tex]

y =[tex]1500(1.012)^{x}[/tex]

Hence, system of equations can Brandon use to determine the x and y form the two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]

Answer:

25.899sq.metres

Step-by-step explanation:

Area of this section of wood = Area of the sector

Area of the sector = theta/360 * πr²

r is the radius

theta is the central angle

Substitute

Area of the sector = 85.3/360 * πr²

Area of the sector = 85.3/360 * 3.14(5.90)²

Area of the sector = 85.3/360 * 109.3034

Area of the sector = 9,323.58002/360

Area of the sector = 25.899

Hence the area of the section of wood  is 25.899sq.metres
