I really really really need your help

i dont know what it is i can barley see

Answer:

Step-by-step explanation:

For number 1: They are alternate interior angles, so you can set them equal to each other and find the answer that way. The pic is a bit blurry, but I think it's 4x=136, which is simplified to x=34.

For number 2: These are supplementary angles, which means that they add up to 180. 180-125 is 55, which means that 3x+1=55. Simplifying that, x=18.

Number 3: Once again alternate interior angles, which means that 53=x-11. Simplify that and you get x=64

Number 4: These are same side interior angles, and they are supplementary/add up to 180. x+12+110=180. Solved: x=58

Number 5: Same side interior angles. I cant make out the exact numbers on the picture, but basically you add them together and set that equal to 180, then solve like i did above.

Number 6: Alternate interior, so just set them equal to eachother and solve.

Number 7: Same side interior, so add them and set the whole thing equal to 180 like in number 4. Answer: x=10

Number 8: Alternate interior, so just set them equal to eachother. Answer: x=20

Hopefully this helped you understand better, have a great day!

Step-by-step explanation:

C.P=5×1=Rs.5

S.P.=4×1=Rs.4

Loss=C.P.=S.P.

=Rs.5-Rs.4

=Re.1

loss%=loss/C.P ×100

=1/5×100%

=20%

( 2x − 27 ) ( −x + 15 )

= ( 2x + −27 ) ( −x + 15 )

= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )

= −2x^2 + 30x + 27x − 405

= −2x^2 + 57x − 405

Answer:

69

Step-by-step explanation:

you take the sum of the square root and divide by the denominator

Answer:

16.03

Step-by-step explanation:

In triangle ABC angle c = 180-78-40 = 62 degrees

For the triangles to be congruent angle z must equal angle C

Solve for x:

2x + 8 = 62

Subtract 8 from both sides:

2x = 54

Divide both sides by 2:

X = 27

Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.

A. False

B. True

C. True

Thus, the total number of boards required is 2148.

Step-by-step explanation:

Each section of fence contains 12 boards

So, the number of boards required for 179 section of fence is

= 179 x 12 = 2148 boards

Answer:

x=-13

Step-by-step explanation:

-4+4x=-56

add 4 on both sides

4x=-52

divide 4 on both sides

x=-13

Answer:

x=-13

Step-by-step explanation:

-4 + 4x = -56

+4. +4

4x = -52

÷4. ÷4

x = -13

The company needs to sell 8 units in order for the net income to equal $0

The net income function is given as:

[tex]f(x) = 9x^2 - 54x - 144[/tex]

When the net income is 0, then f(x)  = 0.

So, we have:

[tex]9x^2 - 54x - 144 = 0[/tex]

Divide through by 9

[tex]x^2 - 6x - 16 = 0[/tex]

Expand the above equation

[tex]x^2 +2x- 8x - 16 = 0[/tex]

Factorize the above equation

[tex]x(x +2)- 8(x + 2) = 0[/tex]

Factor out x + 2 in the above equation

[tex](x - 8)(x + 2) = 0[/tex]

Split and solve for x

[tex]x = 8[/tex] or [tex]x =-2[/tex]

The units of product cannot be negative.

So, the value of x is [tex]x = 8[/tex]

Hence, the company needs to sell 8 units

Answer:

Step-by-step explanation:

Here we want the side length of x, which is adjacent to the angle 31 degrees. Cosine is the ratio we want because it is adj/hypotenuse.

Here's our basic equation:

cos31=x/17

or

17 * cos31=x

Put this into the calculator and you get around 15.6

Step-by-step explanation:

To find the area of a circle, you use the formula:

[tex]\pi \: {r}^{2} [/tex]

In your problem the radius is 34, so when you square that, multiply is by pi, and round it to the nearest whole number, the answer is 3,632.

Answer: 18

Step-by-step explanation:

Find the scale factor: 144/36= 4. But scale factor of area is r^2=4=> r= 2

Hypotenuse of small triangle is:
