Answer:

C.  x=2.5, DC=7.5, EC=15

Step-by-step explanation:

since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.

Now you can just do 2.5+5=7.5 so DC=7.5

Answer:

186

Step-by-step explanation:

PEMDAS

First do 46 x 8 = 368 then divide that by 2, which would be, 184. Then add 2 to 184 and you get 186. :)

Answer:

  see attached

Step-by-step explanation:

The break-even point is on both curves. The y-intercept can be used for the other point in each case.

The break-even point is where cost and revenue are the same:

  20/3x +50 = 10x

  50 = 10/3x . . . . . . . . subtract 20/3x

  15 = x . . . . . multiply by 3/10

  r = c = 10(15) = 150 . . . . for x = 10

Two points you can use for graphing the lines are ...

  cost: (0, 50) and (15, 150)

  revenue: (0, 0) and (15, 150)

Answer:

x = 5

Step-by-step explanation:

Here, from what we have, the angle and the sides facing it are equal

Since we have pi oh both sides

Thus;

6x + 6 = 9x-9

9x-6x = 9 + 6

3x = 15

x = 15/3

x = 5

Answer:

Step-by-step explanation:

sin(x) + tan(x) =sin(X) + sin(x)/cos(x)

=sinx(1+1/cosx)

=Sinx(1+secx)

=1+secx/cosecx. (Since sinx=1/cosecx)

Hence LHS=RHS proved

Answer:

B.)58?

Step-by-step explanation:

Hope I helped..

Answer:

b: 58

Step-by-step explanation:

AC=37

BC=5X+6

AB=2X + 3

2x + 3 + 5x + 6 = 37

7x + 9 = 37

7x = 28

x = 4

BC = 5(4) + 6

BC = 26

Answer = BC = 26

Answer:

The sum of the two solutions to the given equation is 1/3.

Step-by-step explanation:

Nature of Roots of a Second-Degree Equation

Given a quadratic equation:

[tex]ax^2 + bx + c = 0[/tex]

The roots of the equation are:

[tex]\displaystyle x_1=\frac{-b+ \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\displaystyle x_2=\frac{-b- \sqrt{b^2-4ac}}{2a}[/tex]

The sum of the roots is:

[tex]\displaystyle x_1+x_2=-\frac{b}{a}[/tex]

The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term, divided by the leading coefficient.

We are given the equation:

[tex]3x^2 - x = 4[/tex]

Rearranging:

[tex]3x^2 - x - 4=0[/tex]

The coefficient b is b=-1, and the leading coefficient is a=3, thus the sum of the roots is:

[tex]\displaystyle x_1+x_2=-\frac{-1}{3}[/tex]

[tex]\displaystyle x_1+x_2=\frac{1}{3}[/tex]

The sum of the two solutions to the given equation is 1/3.

Answer:

(1 + 2i)(1 - 2i)

Step-by-step explanation:

Multiplying a complex number and its conjugate results in a real number.

Thus

1 + 2i and 1 - 2i are conjugates

(1 + 2i)(1 - 2i) ← expand using FOIL

= 1 - 2I + 2I - 4I² [ note i² = - 1 ]

= 1 - 4(- 1)

= 1 + 4

= 5 ← a real number

Answer:

25m

Step-by-step explanation:

/_B=pie/4=45°

since we have /_C=90° then this triangle is a right isosceles triangle

so sides are equal

so a=b= 25 m

Answer:

y=2/3x-16/3    

Step-by-step explanation:

ok ill show you how to do one question since the rest will take too long so what you do is

equation is y=mx+b right

so you have slope and these points (2,-4) and m=2/3

y=2/3x +b right

now all you do is sub in x and y which are ur given points

-4=2/3 (2) +b

now you solve for b

-4 = 4/3 + b

-4-4/3 = b

-12/3 - 4/3 = b

-16/3=b so therefore

y=2/3x-16/3    

Answer:

120 minutes or 2 hours I think

Step-by-step explanation:

ok so you want to figure out how many hours it will take for her to bake 48 cookies. It takes 15 minutes to bake 6 cookies.

So 6x8=48 cookies.

Multiply 15 minutes times 8 since one batch of cookies (6) 15 minutes long and she wants to bake 48 cookies.

15x8=120

That's 120 minutes, but you want how many HOURS it takes.

there are 60 minutes on a hour so you will take 120 divided by 60

120/60= 2

To check, multiply 60x2= 120.

Hope this helps!
