Answer:
A) m < -175/k and B) 3c/5 - 11
Step-by-step explanation:
A) Add 90 to both sides. -mk > 175.
Next, divide both sides by -k. Because you divide by a negative, don't forget to reverse the sign!
m < -175/k.
B) Subtract 3c from both sides.
-5f = 55 - 3c.
Now multiply both sides by -1/5.
f = 3c/5 - 11
Answer: e) 2(n+1)
Step-by-step explanation:
De las opcionas dadas, e) 2(n+1) es la correcta.
Empecemos por explicar la siguiente regla:
(número par)(número par)=número par
(número par)(número impar)=número par
(número impar)(número impar)=número impar
Ahora bien, en la expresión 2(n+1) el resultado de lo que se encuentra dentro del paréntesis va a ser multiplicado por 2, el cual es un número par, por lo tanto el resultado final va a ser un número par independientemente de si lo que está en el paréntesis es par o impar.
Por ejemplo, si elegimos 1 que es impar:
2(1+1)=2(2)=4
El resultado es par.
Si probamos con las otras opciones, los resultados serán impares:
a) 2n +1
2(1)+1=2+1=3 impar
b) n(n+2)
1(1+2)=1(3)=3 impar
c) n+(n-1)
1+(1-1)=1+0=1 impar
The total area of the composite figure will be equal to 488 square meters.
The space occupied by any two-dimensional figure in a plane is called the area. Here we have two figures a rectangle and a right-angle triangle.
We have the following data:-
Total area = Area of rectangle + Area of triangle
Total area = (L x W) + (1 / 2)[ B x H]
Total area = ( 22 x 17 ) + (1 / 2)[ 12 x 19 ]
Total area = ( 374 + 114 ) = 488 sq2uare meters
Therefore the total area of the composite figure will be equal to 488 square meters.

Answer:
Explanation
The capacity of the shelter is a constant. It is 80 people × 14 days.
That is an inverse relation: the product of the number of people and the number of days will be always the same.
As the number of people decreases the number of days that the food lasts increases, in a proportion such that the product of the days and the number of people is the same.
Thus, for 32 people the number of days the food lasts is x, such that:
Solving for x:
The food will last 35 days.
Answer: 35 days
Step-by-step explanation:
Given: A shelter has enough food to feed an average of 80 hungry people a day for 14 days.
Let y be the number of days if 32 people are at the shelter .
The number of hungry people and number of days are in inverse proportion
Therefore,
Therefore, if an average of 32 people are at the shelter each day, the food will last for 35 days.
