to work out how much a 20lb turkey would cost you have to divide the cost of a 12lb turkey by 12 (15.25/12= 1.27083) as well as dividing the 12lbs by 12 (12/12= 1) then times both numbers by 20 (1.27083 X 20 = 25.42 (rounded)) (1 X 20 = 20) and you have 20lbs turkey=$25.42

John lays tile for a living. While trying to create the perfect design for his client, he then drew this pattern containing two right angles and an isosceles triangle.

For the triangles to fit together perfectly, John must determine the measure of angles 1, 2, and 3.

Answers

Answer:

Angle 1= 58

Angle 2= 64

Angle 3= 58

Step-by-step explanation:

The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle

then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2

Answer:

angle 1 = 32

angle 2 = 116

angle 3 = 32

What is the measure of all exterior angles of a pentagon

Answers

Answer:

72 degrees for each exterior angle and 360 degrees for all of them summed.

Step-by-step explanation:

An exterior angle of a polygon is the angle between the line extending one of its sides and the next side.  As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees.  All these angles are equal, so each one is 360/n.

For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

The answer is sqrt 64.

64^1/2 = sqrt 64

if y varies directly as the square root of x and y=3, x=3. calculate y when x=64​

Answers

Answer:

  y = 64√3

Step-by-step explanation:

Step(i):-

Given that the 'y' varies directly as √x

    ⇒ y∝ √x

    ⇒  y = k√x

Put y=3 and x=3

       3 = k ×√3

   √3  k = √3×√3

After cancellation '√3' on both sides, we get

      k = √3

Step(ii):-

   Given that x=64 and k = √3

We have a function   y = k√x ..(i)

substitute x =64 and k = √3 in equation (i)

               y = √3 × 64

             y = 64√3

Cual es el valor de un esfero cuando la docena se compra en $7848? Area de un triangulo de 9 unidades de base y 6 unidades de altura? Cien veces la suma de 4.5 con 2.71 Porfavooor es para una tarea de mañana D:

Answers

Answer:

a) $654

b) 27 unidades cuadradas

c) 721

Step-by-step explanation:

a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?

Una docena = 12

Por eso:

12 bolígrafos = $ 7848

1 bolígrafo = $ x

Cruz multiplicar

12 bolígrafos × $ x = 1 bolígrafo × $ 7848

$ x = 1 bolígrafo × $ 7848/12

$ x = $654

b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?

Área de un triángulo =

= 1/2 × Base × Altura

1/2 × 9 × 6

= 27 unidades cuadradas

c) Cien veces la suma de 4.5 con 2.71

Esto se calcula como:

100 × (4,5 + 2,71)

= 100 × (7.21)

= 721
