Answer:

5x-6+7x+12=180

Step-by-step explanation:

5x+7x = 12x

12x - 6 +12 = 180

add 12 and -6 to get 6.

12x + 6 = 180

      subtract 6 from both sides to get 174.

12x = 174.

now divide both sides by 12 to get x = 14.5 or 29/2 which cancels out to 6

Answer: 1=60°

Step-by-step explanation:

First, let's take our given angle of 30°

30° is in a right triangle, so the angles must be 90°, 60°, and 30°

Now the angle that is 45° makes angle 1 congruent to angle 60°

Meaning angle 1 is 60°

Answer:

m < 1 = 60

Step-by-step explanation:

Since the transversal is perpendicular to m,

it implies that the triangle formed by the perpendicular transversal, the slant transversal and the line m is a right angle triangle.

We use vertically opposite angles property to bring m<1 in to the right triangle.

We now use the sum of interior angles property to obtain,

m < 1 + 30 + 90 = 180

This implies that,

m  < 1 + 120 + 180

We group like terms to obtain,

m < 1 = 180 - 120

This means that,

m < 1 = 60

We could have also used corresponding angles property, then

m < 1 + 30 = 90

m < 1 = 90 - 30

m < 1 = 60

Answer:

There are 1,679,616 ways to answer the test

Step-by-step explanation:

Here, we want to get the number of ways to answer the test

From the question, we have that there are 8 questions, with each having 6 possible answers

Hence, the total number of answers to pick from is 8 * 6 = 48

We are to pick 6 out of this total 48, with 1 option per question

So in the first, we are picking 1 out of 6

The number of ways here is;

6 C 1 = 6 ways

The next, we have 6 ways also , up to the 8th question

So, the total number of ways will be;

6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 6^8 =

1,679,616

Answer:

Step-by-step explanation:

sureface area of rectanglur object is the sum of the six sides

     Area = Length x Width

   SArea = Top Area + Bottom Area + Front Area + Back Area + Left Side Area

                 + Right Side Area

        since the top and bottom have equal  area  =  long x wide

                  the front and back have equal  area    = long x tall

                  and both sides have equal area  =  wide x tall

              I summed the bottom front and side areas each times 2

   SArea = 2(Bottom Area) + 2(Front Area) + 2(Side Area)

                 factor out the 2 and added the area formulas for the bottom front

                 and side

              = 2 [ (long x wide) + (long x tall) + (wide x tall)]

              = 2 [ (9 x 4) + (9 x 6) + (4 x 6)]

              = 2 [ (9)(4) + (9)(6) + (4)(6)]

              = 2(    36   +   54   + 24 )

              = 2( 114)

              =   ????    What is 2 times 114  ????       You can finish this part.

Answer:

Percent sales tax = 9%

Step-by-step explanation:

Listed price = $29

Price with tax = $31.61

Amount of tax = Price with tax - Listed price

= $31.61 - $29

= $2.61

Find the percent sales tax.

Percent sales tax = $2.61/$29 × 100

= 0.09 × 100

= 9%

Percent sales tax = 9%

m∠3 = 127°

Step-by-step explanation:

From the given picture,

Two parallel lines have been given.

Angle 3 and another angle measuring 53° are located on a point of a straight line.

Therefore, both the angles will be supplementary.

m(∠3) + 53° = 180° [Property of supplementary angles]

m(∠3) = 180° - 53°

          = 127°

Soro did not make any erro

Step-by-step explanation:

Soro bought a $50.00 bus card at the beginning of the week. Each bus ride costs $2.50. He needs to have at least $20.00 on his card at the end of this month.

Let her number of rides he can take be written as x

$50 - $2.50 × x ≥ $20

50 - 2.5x ≥ 20

-2.5x ≥ 20 - 50

-2.5x ≥ -30

x ≥ -30/-2.5

x ≥ 12 rides

Answer:

The picture is kinda blurry so I hope I've got it right.

a) x = 20°

b) x = 70°

c) x = 50°

Step-by-step explanation:

a) 2x + 3x + 4x = 180°

9x = 180°

x = 50°

b) (x - 20°) + (x - 20°) + (x + 10°) = 180°

3x - 30° = 180°

3x = 210°

x = 70°

c) (x + 10°) + (x + 20°) + x = 180°

3x + 30° = 180°

3x = 150°

x = 50°

Answer:

4a[tex]\sqrt{x}[/tex]41

Step-by-step explanation:

12*2+9x2= Perimeter.

The perimeter P of rhombus is given as

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

The diagonals of rhombus bisect each other at right angles and it has same perimeter as that of a square.

From this property stated above we can formulate  side of rhombus is below in equation (1)

Side and  diagonals of rhombus have following relation

[tex]\rm Let \; the \; side \; of\; rhombus = s\\Length\; of \; first \; diagonal = 8a\\ Length\; of \; second \; diagonal = 10a\\\\According \; to \; the \; identity\; for\; area \; of\; rhombus \\ s^2 = (p/2)^2 +(q/2)^2 ....(1) \\where \; p \; and\; q \; are\; the \; diagonals.[/tex]

so

[tex]\rm s^2 = (10a/2)^2 + (8a/2)^2\\s^2 = 25a^2 + 16a^2 = 41 a^2 \\s= \sqrt{41}a ......(2)[/tex]

Equation (2) represents side of rhombus

So the perimeter P of rhombus is given as

[tex]\rm P = 4\times s[/tex]

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

The perimeter P of rhombus is given as

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]
