Answer:
The correct prove will be:

Step-by-step explanation:

Multiply and Divide by 
= 
⇒ Let
= Ф and 7Ф = 
= sin2Ф sin3Ф sin5Ф ÷ 2cosФ
= 1/2(2sin2Фsin5Ф)sin3Ф ÷ 2cosФ
= (cos3Ф - cos7Ф) sin3Ф ÷ 4cosФ
= 1/2(2cos3Ф sin3Ф) ÷ 4cosФ ∵cos7Ф = 0
= sin6Ф ÷ 8cosФ
= sin(7Ф - Ф) ÷ 8cosФ
= (sin7ФcosФ - cos7ФsinФ) ÷ 8cosФ ∵sin7Ф = 1
= cosФ ÷ 8cosФ
= 1/8
Hence, The correct prove will be:

Answer:
Cantidad de raciones= 8.75 raciones
Step-by-step explanation:
Dada la siguiente información:
Para hacer una ración de puré de papa se necesita 1/5 de kg.
<u>Vamos a pasar las cantidades a décimales:</u>
Ración puré= 0.2kg
Kg de papa= 7/4= 1.75 kg
<u>Ahora, dividimos la cantidad total por la cantidad unitaria:</u>
Cantidad de raciones= 1.75/0.2
Cantidad de raciones= 8.75 raciones
Answer:
10.8kg
Step-by-step explanation:
Before he was on the diet he already weighed 80 kilograms, so it is not important to determining how much weight we gains in two months. Instead we need to focus on the 5.4t part of the equation. t represents the number of months so we need to substitute 2 for t and you get
5.4t
5.4(2)
10.8kg
