Answer:

24 edges, 24 vertices, 8 faces - For that weird Cylender thing.

Step-by-step explanation:

There are six faces on sides (and two on both tops, these don´t have vertices or edges of their own), 4 edges on each one, 4 vertices on each one.

Answer:

There are 6 faces

One up one down one front one backs one right one left

12 edges and 8 ventricles

We will form the equations for this problem:

(1) 1100*y + z = 113

(2) 1500*y + z = 153

z = ? Monthly administration fee is notated with z, and that is the this problem's question.

Number of kilowatt hours of electricity used are numbers 1100 and 1500 respectively.

Cost per kilowatt hour is notated with y, but its value is not asked in this math problem, but we can calculate it anyway.

The problem becomes two equations with two unknowns, it is a system, and can be solved with method of replacement:

(1) 1100*y + z = 113

(2) 1500*y + z = 153

----------------------------

(1) z = 113 - 1100*y [insert value of z (right side) into (2) equation instead of z]:

(2) 1500*y + (113 - 1100*y) = 153

-------------------------------------------------

(1) z = 113 - 1100*y

(2) 1500*y + 113 - 1100*y = 153

------------------------------------------------

(1) z = 113 - 1100*y

(2) 400*y + 113 = 153

------------------------------------------------

(1) z = 113 - 1100*y

(2) 400*y = 153 - 113

------------------------------------------------

(1) z = 113 - 1100*y

(2) 400*y = 40

------------------------------------------------

(1) z = 113 - 1100*y

(2) y = 40/400

------------------------------------------------

(1) z = 113 - 1100*y

(2) y = 1/10

------------------------------------------------

if we insert the obtained value of y into (1) equation, we get the value of z:

(1) z = 113 - 1100*(1/10)

(1) z = 113 - 110

(1) z = 3 dollars is the monthly fee.

Answer:

y=(x-1)(x-4) & 100°

Step-by-step explanation:

Graph

1) there are x-intercepts at 1 and 4so you set those equal to x

ex. x=1 x=4

2) then subtract them over to equal 0 and set it equal to y

ex. y=(x-1)(x-4)

Angle

*IMPORTANT* Straight lines are equal to 180°

∠CBD = 80°

1) So you just subtract ∠CBD from 180°

ex. 180° - 80° = 100°

Answer:

the answer is 91,5007.50 dollars

Step-by-step explanation:

find the first year you would do 83,000 times 105% and that would equal 87,150 next you would do 87,150 times 105% and I would equal to 91,507.50

Answer:

83830

Step-by-step explanation:

because 5percent of 83000 is 412 and 412 plus 412 is 830 and plus 83830

Answer:

[tex] \sin( \alpha ) = \frac{4}{5} [/tex]

Step-by-step explanation:

as if we form an imaginary triangle with this line as hypotenuse

we get

using Pythagoras theorem:-

hyponteuse ² = perpendicular ² + base²

hyp² = 4² + 3²

hyp² = 16 + 9

[tex]hyp = \sqrt{25} [/tex]

hyp = 5 units

[tex] \sin( \theta ) = \frac{perpendicular}{hypotenuse} \\ \sin( \theta) = \frac{4}{5} [/tex]

Answer: 25

Step-by-step explanation: I just entered the equation into my calculator like so.

A negative number times a negative number equals a positive number.

I hope this helps, have a nice day.

Answer:

c(12 + 9 + 6)

12(2.25c)

Step-by-step explanation:

12c + 12 (3/4c) + 12 (1/2c)

12(1c) + 12(3/4c) + 12 (1/2c)

12(c + 3/4c + 1/2c)

12(2 1/4c)

12(2.25c)

Or

12c + 12 (3/4c) + 12 (1/2c)

12c + 9c + 6c

c(12 + 9 + 6)

Answer:

Step-by-step explanation:

sin(x) = opposite over hypotenuse

= 3/(3sqrt(2))

= 1/sqrt(2)

= sqrt(2)/2

x = arcsin( sqrt(2)/2 )

= arcsin( sqrt(2)/2 )

= 45°

Answer:

[tex] { \tt{x + y + 2 = 0}} \\ y = - x - 2 \\ \\ { \tt{x + y - 2 = 0}} \\ y = - x + 2 \\ \\ { \tt{x - y - 2 = 0}} \\ - y = - x + 2 \\ y = x - 2[/tex]

Answer:

11.17 tonnes was in the fourth and final load.

Step-by-step explanation:

11.25 + 12.76 + 12.82 = 36.83 > total of the first 3 loads.

x = 4th load.

36.83 + x = 48

x = 48 - 36.83

x = 11.17

The domain of [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex].

The range of the given function [tex]y = tanx[/tex] is the set of all real numbers.

The domain of a function is the set of values that we are allowed to plug into our function.

The range of a function is the set of its possible output values.

According to the given question.

We have a function

[tex]y = tanx[/tex]

The above function can be written as

[tex]y = \frac{sinx}{cosx}[/tex]

⇒ [tex]tanx[/tex] is defined for all values except the values that makes [tex]cosx = 0[/tex], a fraction with denominator is not defined.

And we know that

[tex]cosx = 0 \ \forall \ x \in \frac{(2n+1)\pi }{2} \ where \ n \in Z[/tex]

Hence, for all these values, [tex]tanx[/tex] is not defined.

Therefore, the domain of [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex].

Since, the domain of  [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex], so when we input these values in the given function we get only real numbers.

Therefore, the range of the given function [tex]y = tanx[/tex] is the set of all real numbers.

Thus, option D and B are correct.

Answer:

159.25 meters

Step-by-step explanation:

Using the solution diagram attached ;

From Trigonometric relation, the width, w of the canal can be obtained using :

Tanθ = opposite / Adjacent

Tan 37 = 120 / w

w * tan 37 = 120

w = 120 / tan 37

w = 159.24537 meters

Hence, width of canal is 159.25 meters

Answer:

1/3 x 1/3 x 1/3(volume of small cube) = 1/27

2/3 x 7/3 x 4/3(volume of figure shown) = 2 2/27

Now we divide to see how many cubes can fit.:

2 2/27(make improper fraction) divided by 1/27 = 56 small little cubes can fit.

Answer:

0.0233

Step-by-step explanation:

We are told that 40% of students prefer to use pencils over pens for their assignments.

This means 40 out of 100 students prefer to use pencils over pens.

Thus, for the first draw, P(pencil over pens for first draw) = 40/100

Since person using pencil over pens is selected without replacement, then, we now have a sample space of 99;

Second draw; P(pencil over pens for 2nd draw) = 39/99

Similarly, for third draw; P(pencil over pens for 3rd draw) = 38/98

For fourth draw; P(pencil over pens for 4th draw) = 37/97

Thus;

probability that you randomly select four students and all four prefer to use pencils over pens is;

P(all four prefer pencils over pens) = (40/100) × (39/99) × (38/98) × (37/97) = 0.0233
