A beanie hat is to be made from a piece of fabric and one square metre of this fabric weighs 470g.
Ainat [17]

Answer:

The hat weight = 81.166 g

Step-by-step explanation:

∵The figure formed by a rectangle and two identical semi-circle

∵ The length of the rectangle = 52 cm = 0.52 m

∴ The length of the two diameter = 52 cm = 0.52 m

∴ The radius of the semi-circle = 52 ÷ 4 = 13 cm = 0.13 m

∴ The width of the rectangle = 36 - 13 = 23 cm = 0.23 m

∴ The area of the rectangle = 0.52 × 0.23 = 0.1196 m²

∴ The area of the semi-circles = π (0.13)² = 0.0531 m²

∴ The area of the hat = 0.1196 + 0.0531 = 0.17269292 m²

∵ 1 m² = 470 g

∴ The weight of the hat = 0.17269292 × 470 = 81.16567 ≅ 81.166 g

compará y ordena de mayor a menor las siguientes cantidades 23.4 ,15/20 ,32.245,.056,4/10,50/100,8/9,.009,9/1000 y 54.45​
nignag [31]

Answer:

El orden de mayor a menor es:

54.45 ; 32.245 ; 23.4 ; 8/9 ; 15/20 ; 50/100 ; 4/10 ; 0.056 ; 9/1000

Step-by-step explanation:

El mayor número será el que tenga el mayor entero, o  si tienen el mismo entero será aquel que tenga el primer decimal mayor de izquierda a derecha,  o si tienen el mismo se observa el siguiente decimal y así sucesivamente.

Para ordenar y comparar las cantidades es conveniente en primer lugar pasar todos los números a decimales. Para convertir una fracción en un decimal, debes dividir el numerador entre el denominador.

Entonces, en este caso el valor decimal de cada cantidad (o una aproximación) es:

23.4

15/20= 0.75

32.245

0.056

4/10= 0.4

50/100= 0.5

8/9= 0.8888

0.009

9/1000= 0.009

54.45​

Entonces <u><em>el orden de mayor a menor es: </em></u>

<u><em> 54.45 ; 32.245 ; 23.4 ; 8/9 = 0.8888 ; 15/20 = 0.75 ; 50/100 = 0.5 ; 4/10 = 0.4 ; 0.056 ; 9/1000 = 0.009</em></u>

Write the word sentence as an equation. Then solve.<br><br> 10 more than a number c is 3.
ira [324]

Answer:

10+c=3

Step-by-step explanation:

to solve this you would then subtract 10 from both sides, to get c by itself.

3-10= -7

Your answer would be -7 and the equation would be 10+c=3.
