CHCK Farms raises hens and roosters. They have enough space to raise at most 300 birds per year. Each hen eats 80 pounds of food

per year, and each rooster eats 60 pounds of food per year. The business can only afford 20,000 pounds of food per year. The graph below shows the solution set of a system of linear inequalities that represents this situation.

<u>Answer</u>:

The number of hens is 100 and the number of roosters is 200.

<u>Step-by-step explanation:</u>

Let the number of hens be x and the number of roosters be y

then the total number of  hens and roosters, is 300

so,

x+y \leq 300----------------------------(1)

Also  the hen eats 80 pounds of food per year and roosters eats 60 pounds of food per year,

80x+60y \leq 20000----------------(2)

To solve the equations , multilpy eq(1) by 80

80x+80y \leq 24000------------------(3)

Subracting (2) from (3)

20y \leq 4000

y \leq 200

substituting y in eq(1) we get

x+200 \leq 300

x \leq 300-200

x \leq 100

What is the sum of the first 75 even numbers starting with 2? Enter your answer in the box.
vova2212 [387]

Answer:

5700

Step-by-step explanation:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The number series 2, 4, 6, 8, 10, 12, .  .  .  .  , 150.

The first term a = 2

The common difference d = 2

Total number of terms n = 75

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 75/2 x (2 + 150)

= (75 x 152)/ 2

= 11400/2

2 + 4 + 6 + 8 + 10 + 12 + .  .  .  .   + 150 = 5700

Therefore, 5700 is the sum of first 75 even numbers.
