The property used to arrive at line 2 is the additive property of equalities

The additive property of equalities states that for real numbers if x = y : then x + z = y + z

For example if 2 = 2 , then 2 + 1 = 3

In order to arrive at line 2, x and 2x were added together to arrive at 3x

The distributive property was used to arrive at line. The property states that : x(1 + 2) = x + 2x

Subtractive property of equalities was used to arrive at line 3

Answer:

the probability that the ext order will be shrimp = 27.78%

Step-by-step explanation:

Vegetable 333

Chicken 666

Pork 222

Beef 222

Shrimp 555

total = 1,998

P (shrimp) = 555 / 1,998 = 0.2777 or 27.78%

in case the numbers in the orders were:

Vegetable 3

Chicken 6

Pork 2

Beef 2

Shrimp 5

total = 18

P (shrimp) = 5 / 18 = 0.2777 or 27.78%

The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.

Considere um triângulo retângulo, cujos ângulos agudos a e b satisfazem à condição cos a = 0,8 e cos b = 0,6 Determine a área de

Anni [7]

Answer:

7.5 cm^2

Step-by-step explanation:

Aqui, temos Cos A = 0,8 = 8/10 = 4/5.

Cos B = 0,6 = 6/10 = 3/5.

O que isto significa é que os dois outros lados do triângulo retângulo são 3 cm e 5 cm, respectivamente.

Isso ocorre porque, o oposto do ângulo agudo A é adjacente ao ângulo agudo B e vice-versa.

Portanto, a partir dos valores de ambos, podemos obter os dois outros lados.

Matematicamente, a área da direita é 1/2 * b * h b e h são 3 e 5, respectivamente.

Assim, área = 1/2 * 3 * 5 = 7,5 cm ^ 2
