If chicken costs 10¢ per ounce and grain costs 1¢ per ounce, how many ounces of each should
Ruff use in each bag of dog food to minimize cost?
The cost of the chicken and the grain are illustrations of linear programming
The minimized cost is 12¢
How to determine the minimized costRepresent the number of chicken with x and the number of grain with y.
So, the objective function is
Min Z = 10x + y
The constraints are not given.
So, the function cannot be minimized.
However, assume the minimum feasible values of x and y are (1,2), the minimized cost would be:
Z = 10 * 1 + 2
Z = 12
Hence, the minimized cost is 12¢

Answer:
y = 9 - 3x
Step-by-step explanation:
9x + 3y - 27 = 0 ( add 27 to both sides )
9x + 3y = 27 ( subtract 9x from both sides )
3y = 27 - 9x ( divide through by 3 )

Write the inequality:
Two less than twice a number is less than a half.
Answer:
2x-2<1/2
Step-by-step explanation:
when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.

The length of a rectangle is 2 centimeters longer than its width.
If the perimeter of the rectangle is 64 centimeters, find its length and width.
Answer: 15
Step-by-step explanation:
Let the length of the width = w.
Then, the length of the length is w + 2.
The perimeter of a rectangle is 2*length + 2*width.
Therefore, 2*(w+2) + 2*w = 64
2w + 4 + 2w = 64
4w + 4 = 64
4w = 60
w = 15

Michael buys a pair of jeans that regularly costs $62. The jeans were discounted 30%. How much money did Michael pay for the jeans?
Plss help
Answer:
$43.40
Step-by-step explanation:
First, you would have to find out how much was discounted. To find this, you multiply $62.00 (the total) by 30% (the discount sale). You will end up getting $18.60. Finally, you can subtract $18.60 from the original total which was $62.00 to get $43.40 after the discount.

Answer:
x = 11
Step-by-step explanation:
(3x + 28) + (5x + 52) + ( 2x - 10) = 180
(3x + 5x + 2x) + (28 + 52 - 10) = 180
10x + 70 = 180
10x = 180 - 70
10x = 110
x = 11
Answer:
x= 11
Step-by-step explanation:
(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)
10x+80-10= 180
10x+70=180
10x=180-70
10x=110
x=110÷10
x=11

$4,696,000
$3,712,000
The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000
Exponential functionAn exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y represent the average annual salary, x years since 2000, hence, from table:
At (2000, 1116000), that is (0, 1116000):
1116000 = ab⁰
a = 1116000
At (20, 3193000):
3193000 = 1116000(b)²⁰
b = 1.05
The salary in 2025 ( x = 25) is:
y = 1116000(1.05)²⁵ = 4152719.5
The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000

Find the value of x. Leave your answer in simplest radical form.
Answer:
First you need to find at least two dimensions of the triangle containing a side length of x. The triangle of the top can be used for that. The hypothenuse for the 7,3 triangle is [tex]\sqrt{58}[/tex].
Now we can use the other triangle with sides of x,[tex]\sqrt{58}[/tex], and a hypothenuse of 9 to find x.
x^2 + [tex]\sqrt{58}^2[/tex] = 9^2
simplify
x^2 + 58 = 81
subtract 58 from both sides
x^2 = 23
x = [tex]\sqrt{23\\}[/tex]
and since this radical cannot be simplified further that is your answer.
Step-by-step explanation:
Step-by-step explanation:
Pythagoras.
c² = a² + b²
c being the Hypotenuse (the side opposite of the right angle).
so, the length of the rectangle is the Hypotenuse of the right-angled triangle on the top :
length² = 7² + 3² = 49 + 9 = 58
length = sqrt(58)
the diagonal of the rectangle is again the Hypotenuse of the right-angled triangle of length (sqrt(58)), width (x) and diagonal (9) of the rectangle.
so, we have
9² = sqrt(58)² + x² = 58 + x²
81 = 58 + x²
23 = x²
x = sqrt(23)
Joe's total bill for pizza and soft drinks was $27.50. He left a
20% tip for their server. How much tip did he leave?
Answer:
$5.50
Step-by-step explanation:
100% of the total bill was $27.50
10% will be 100% divided by 10
10% = $27.50 ÷ 10
10% = $2.75
20% will be double 10%
20% = £2.75 × 2
20% = $5.50

Anna selects a positive multiple of 4 that is less than forty, and Becky selects a positive multiple of 3 that is less than sixty. What is the probability that they pick the same number?
I will mark brainliest!
Answer:
3/171
Step-by-step explanation:
The problem can be simplified into finding probability that Anna and Becky select 12 or 24 or 36 which are less than 40 and multiples of 3 and 4.
Probability of Anna selecting 12 = 1/9
Probability of Becky selecting 12 = 1/19
Probability of Anna and Becky selecting 12 = 1/9 * 1/19 = 1/171
Probability of Anna and Becky selecting 12 or 24 or 36 = 3* 1/171 = 3/171
