Answer:

31

Step-by-step explanation:

The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.

Answer and Step-by-step explanation:

We know that a is equal to 25.

Let's subtract that from the entire angle measure of line segment AB, which is 180.

180 - 25 = 155.

Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.

155 = 2x + 3x

155 = 5x

31 = x

So, the value of x is 31.

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:

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.

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.

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

Step-by-step explanation:

Hey there!

In (a) part we can see that a person delivers approximately 120 newspapers in 3 hours. Kate will deliver 30 × 3 = 90 newspapers. So, (a) part is the answer.

In (b) part, a person delivers 40 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers. So, Kate is faster, (b) option cancelled.

In (c) a person delivers 110 newspapers in 4.5 hours. Kate will deliver 30 × 4.5 = 135 papers, that's again greater. Option (c) cancelled.

Option (d), we can easily cancel it out. But I'm showing the work; a person delivers 20 newspapers in 4 hours, Kate delivers 30 × 4 = 120 newspapers, much faster than the person.

Hence option (a) is the answer.

Answer:

The surface area of the figure is;

36·π cm²

Step-by-step explanation:

The parameters of the figure are;

The shape of the figure = A sphere

The radius of the sphere, r = 3 cm

The surface area of a sphere, A = 4·π·r²

Therefore, for the given sphere, we have;

The surface area of the sphere, A = 4 × π × (3 cm)² = 4 × π × 9 cm²

∴ The surface area of the figure (sphere), A = 36·π cm².

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
