20 points! Identify the solids that form the compos

Troyanec [42]

The composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.

The composite solid's surface area is 225.4 square inches.

Step-by-step explanation:

Step 1:

The given composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.

The surface area of the composite shape is given by summing the individual surface areas.

The composite shape's surface area = The cube's surface area + the cylinder's surface area.

Step 2:

Any cube's surface area is calculated by multiplying 6 with the square of the side length ( $a^2$ ).

The cube's surface area = $6a^2$ = $6(5^{2} )$ = $150$ square inches.

Step 3:

Any cylinder's surface area is calculated with the following formula;

The cylinder's surface area = $2 \pi r h+2 \pi r^{2}$ = $2 \pi (2) (4)+2 \pi (2)^{2}$ = $75.398$ square inches

Step 4:

The composite shape's surface area = The cube's surface area + the cylinder's surface area.

The composite shape's surface area = 150 + 75.398 = 225.398 square inches. Rounding this off, we get the area as 225.4 square inches.

1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar

Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

En el sistema de ecuaciones, tiene-se que los números son x e y.
Suma de 115, o sea, $x + y = 115$
El número mayor es dos veces más 22 unidades que el otro, o sea, $x = 2y + 22$

----------------

Primero se encuenta el número menor, reemplazando la segunda ecuación en la primera:

$x + y = 115$

$2y + 22 + y = 115$

$3y = 93$

$y = \frac{93}{3}$

$y = 31$

----------------

El número mayor es dado en función de el menor, o sea:

$x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84$

Los números son 31 y 84.

44 +9X3- 35 x 60-20

Roman55 [17]

Answer: -2049. Explanation: Use PEMDAS to solve the equation (parenthesis, exponents, multiplication/division, and addition/subtraction). First multiply the numbers that are being multiplied. You should get 44 + 27 - 2100 - 20. Now start from the beginning, and either add or subtract. The answer is -2049.
