Answer:

Three

Step-by-step explanation:

So to count the number of faces, you look for how many flat sides the the figure  has. Looking at the shape, you see that it has a face on top, on the bottom, to the left and to the right, on the front and at the back.

The given figure has five faces, option D is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The given figure is a triangular prism

A triangular prism is a three-dimensional geometric shape that has two congruent triangular bases and three rectangular faces connecting them. Since each triangular base has one face, there are two faces that are triangular.

Additionally, there are three rectangular faces that connect the triangular bases.

Therefore, a triangular prism has five faces in total.

Area of sector = 132.78 cm² (Approx.)

Step-by-step explanation:

Given:

Angle created by sector = 90°

Diameter of circle = 13 centimeters

Find:

Area of sector

Computation:

Radius of sector = Diameter of circle / 2

Radius of sector = 13 / 2

Radius of sector = 6.5 centimeters

Area of sector = [θ/360]πr²

Area of sector = [90/360][22/7][13]²

Area of sector = [1/4][22/7][169]

Area of sector = [0.25][3.1428][169]

Area of sector = 132.78 cm² (Approx.)

Answer:

C. (x - 3)² = 1

Step-by-step explanation:

Given;

x² - 6x  + 8 = 0

Using completing the square method, the equation above is solved as follows;

x² - 6x  = - 8

Half the coefficient of 'x' (-6), square the result and add it to both sides of the equation;

Half of coefficient of x (-6) = ¹/₂ (-6)  = -3

x² + (-3)² = -8 + (-3)²

(x - 3)² = -8 + 9

(x - 3)² = 1

Thus, the correct option is 'C'

C. (x - 3)² = 1

Answer:

Answer      $625:

Step-by-step explanation:

Since the discount is 24% that means that   $475 is 76% of the total

X is the 100% of the price (before sale)

475...............76%

x..........................100%

cross multiplication

76x  =  475x100

76x = 47500

Divide both sides by 76

x= 625

Answer:

y = 4x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

16x - 4y = - 20 ( subtract 16x from both sides )

- 4y = - 16x - 20 ( divide terms by - 4 )

y = 4x + 5 ← in slope- intercept form

The equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].

What is the slope of line?

The slope of a line gives the measure of its steepness and direction.

The slope of a straight line between two points says [tex](x_1,y_1),(x_2,y_2)[/tex] and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘[tex]m[/tex]’.

As we know that, the equation of a line in slope- intercept form is

[tex]y = mx + c[/tex]

where [tex]m[/tex] is the slope and [tex]c[/tex] is the y-intercept.

So,

[tex]16x - 4y = - 20\\\\-4y=-20-16x\\\\-4y=-(16x+20)\\\\4y=16x+20\\\\y=\frac{16x}{4}+\frac{20}{4}\\\\y=4x+5[/tex]

Hence, the equation of a line into slope-intercept form is [tex]y = 4x + 5[/tex].

Answer:

188.24  (rounded)--- 188.2

Step-by-step explanation:

You want to first find the area of all the the different shapes you have...

you have 2 semicircles   A=  πr²/2    (because it is /2 you don't really need that because in the end you are going to *2 so just make the equation A= πr²)

you have a rectangle A= b*h

you have a triangle A = b*h/2

Semicircles:  A= πr²   =     (3.14) 4²   =  (3.14*16)           =      50.24

rectangle:  A = b*h     =      12*8              =      96

Triangle:   A = b*h/2         =   12 * 7/2         =      84/2        =       42

then you add them up

50.24 + 96 + 42

= 188.24

Answer:

15

Step-by-step explanation:

a² + b² = c²

9² + 12² = c²

81 + 144 = c²

c² = 225

[tex]\sqrt{c^2} =\sqrt{225}[/tex]

c = 15

Answer:

50

Step-by-step explanation:

Angle 1 is inside a triangle. Angles in a triangle add up to 180.

Angle 1 = 180 - 90 - 40 = 50.

Angle 2 is on a straight line (180 degrees), shared with angle 1. Therefore, angle 2 is 180 - Angle 1 = 130. Angle 3 and 4 can be calculated the same way Angle 2 was calculated (1=3, 2=4).

Angle 5 is 180 - 90 - Angle 3 which is 180-90-50 which is 40.

Angle 6 is 180 - Angle 5 = 180 - 40 = 140.

Angle 8 is the same as Angle 6

Finally, Angle 7 is 180-90 = 90.
