Find the surface area

9514 1404 393

Answer:

  15.8

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

so the distance from A to B is ...

  AB = √((-1-5)^2 +(1-(-1))^2) = √((-6)^2 +2^2) = √40 ≈ 6.3

Lengths BC and CA are similarly computed. (A spreadsheet does this nicely.)

The perimeter is the sum of the side lengths. It is ...

  P = AB +BC +CA

  P = 6.3 + 4.1 + 5.4

  P = 15.8

The perimeter of ∆ABC is 15.8 units.

Answer:

28.12

Step-by-step explanation:

No Need To Explain, Just Multiply.

Answer:

28.12

Step-by-step explanation:

a=bh

Step-by-step explanation:

-12 = a(0+2)²-20

-12=4a -20

4a = 20-12

4a=8

a=2

y = 2x²+ 8x -12

=> y = 2 x² + 8 x + -12

2 , 8 , -12

Answer:

B

Step-by-step explanation:

Answer:

Step-by-step explanation:

4 + 5x + x + 2  =  180   {linear pair}

5x + x + 4 + 2 = 180  {Combine like terms}

      6x + 6   = 180  {Subtract 6 form both sides}

              6x = 180 - 6

              6x = 174   {Divide both sides by 6}

                x = 174/6

x = 29

x + 2 = 29 + 2 = 31

5x + 4 = 5*29 + 4 = 145 + 4 = 149

2) 6x + 4 + 32 = 90   {Complementary angles}

           6x + 36 = 90   {Subtract 36 from both sides}

                   6x = 90 - 36

                    6x = 54       {Divide both sides by 6}

                      x = 54/6

x = 9

6x + 4 = 6*9 + 4 = 54 + 4 = 58

Answer:

d: 21%

Step-by-step explanation:

1. add 180+135+105+80=500 total

2. then find the percent of 105 from 500 (Determine the total or whole amount.

Divide the number to be expressed as a percent by the total. In most cases, you'll divide the smaller number by the larger number.

Multiple the resulting value by 100.)

you get an answer of 21%

21% of students chose snowboarding as their favorite sport.

Answer:

Which is the smallest number which leaves remainder 8 and 12 when divided by 28 and 32 respectively? 204.

Step-by-step explanation:

Have a great summer.

Answer:

204 is the smallest number.

Step-by-step explanation:

28 - 8 = 20 and 32 - 12 = 20

The required number will be 20 less than the LCM of 28 and 32.

Prime factorization of 28,

→ 2 × 2 × 7

Prime factorization of 32,

→ 2 × 2 × 2 × 2 × 2

LCM(28, 32) = 2 x 2 x 2 x 2 x 2 x 7 = 224

Hence, the required smallest number,

→ 224 - 20 = 204

Answer:

Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.

Step-by-step explanation:

Answer:

90 + 90 = 180, 45 + 45 = 90

Step-by-step explanation:

Supplementary angles add up to 180 and to be vertical angles they need to be equal to each other so 2x = 180

x = 90

Hence both angles will be equal to 90

Complementary angles add up to 90 and as previously stated, to be vertical angles they need to be equal to each other so 2x = 90

x = 45

Hence both angles equal to 45

Answer:

(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602

Step-by-step explanation:

Primero definamos las operaciones usadas:

El cuadrado de un número N, se escribe como N^2

La raíz cubica de un número M, se escribe como ∛(M)

El producto entre dos números, A y B, se escribe como A*B

Ahora queremos plantear la operación:

"El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14."

Lo podemos separar en partes:

"El producto entre el cuadrado de -7 y la raíz cubica de 1728,..."

esto se escribe como:

(-7)^2*∛(1728)

Ahora, la operacion completa es:

El producto entre el cuadrado de -7 y la raíz cubica de 1728, todo eso sumado 14.

Esto se escribe como:

(-7)^2*∛(1728) + 14

Ahora debemos resolver esta operación.

sabemos que:

(-7)^2 = 49

∛(1728) = 12

Reemplazando esos dos en nuestra operación, obtenemos:

(-7)^2*∛(1728) + 14 = 49*12 + 14 = 588 + 14 = 602

Answer:

13

Step-by-step explanation:

(3 - 2i)(3 + 2i)

FOIL

Answer:

Step-by-step explanation:

let angle p be x

x+27=56 degree (sum of two opposite interior angle is equal to the exterior angle formed)

x=56-27

x=29 degree

therefore p is 29 degree.

Step-by-step explanation:

for the perimeter...

18-6=12

that's to get the slant side

perimeter=10+6+12+12+20

=60

for the area I'm not sure how to solve it sorry!!

Answer:

10 x 6 = 60

20 + 10 = 30, 30 x 12 x 1/2 = 180

180 + 60 = 240 cm2 is your area

6 + 6 = 12, 12 + 10 = 22, 22 + 20 = 42

Now lets find hypotenuse:

10 - 20 = 10, 10 divided by 2 = 5

5^2 + 12^2

25 + 144 = 169

Square root of 169 is 13

Add perimeters:

42 + 13 = 55 cm is your perimeter.

Answer:

Step-by-step explanation:

Does the spinner only have these 3 sections?

If so, the probability of spinning an odd number is 1/3. There are a total of 3 possibilities (denominator), and only 1 is odd (numerator).

The P(odd) is the probability of spinning an odd number that would be equal to 1/3.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

You spin the spinner once.

6, 7, 8

There are a total of 3 possibilities (denominator), and only 1 is odd (numerator).

So, the probability of spinning an odd number = 1/3.
