Answer:
44 cows and 36 ducks.
Step-by-step explanation:
x is ducks and y is cows.
Assuming both have 1 head each, we can write:
x + y = 80.
Let's assume each x(cow) has 4 legs and each y(duck) has two legs.
Then we can add the numbers of legs:
2x + 4y = 248 legs
Now rearrange x + y = 80 to:
x = 80-y
and substitute:
2x + 4y = 248 legs
2(80-y) + 4y = 248 legs
160 - 2y + 4y = 248 legs
2y = 88 legs
y = 44 [There are 44 cows]
Use this value to find the number of ducks:
x + y = 80
44 + y = 80
y = 36 [There are 36 ducks]
========================
Check:
Do 44 cows and 36 ducks have a total of 248 legs?
4*44 + 2*36 = 248 ?
176 + 72 = 248?
YES
Complete the table to determine the cost assigned to ending inventory and cost of goods sold using specific identification
The ending inventory that van be gotten from the table will be $9905 and the cost of goods sold is $5083.

Over which interval is the graph of the parent absolute value function decreasing?.
The graph of the parent absolute value function decreases over (–∞, 0) interval.
What is the parent absolute value function?An absolute value function is a function that contains an algebraic expression within absolute value symbols.
Recall that the absolute value of a number is its distance from 0 on the number line.
The absolute value function is f(x) = |x| is defined as,
[tex]\rm f(x)= x \ if\ x > 0\\\\f(x)= 0 \ if\ x=0\\\\ f(x)=- x \ if\ x < 0\\[/tex]
Observe that the graph is V-shaped.
The vertex of the graph is (0,0).The axis of symmetry (x =0 or y-axis) is the line that divides the graph into two congruent halves.The domain is the set of all real numbers.The range is the set of all real numbers greater than or equal to 0. That is y ≥0.The x-intercept and the y-intercept are both 0.Hence, the graph of the parent absolute value function decreases over (–∞, 0) interval.

Pls help (giving brainliest to first answer)
Answer:
(0, -7) and (5, 0)
Step-by-step explanation:
y-intercept is when x = 0, therefore (0, -7)
x-intercept is when y = 0, therefore (5, 0)
Answer:
X intercept: (5,0) Y intercept: (0,-7)
Step-by-step explanation:
So you want to look at where you have an x value (input) and it's output (y) is 0 for x intercept, and you want to look at the y value (output) and it's input (x) to be 0 for the y intercept, so on the left we see that 5 = 0, and on the right we see that -7 = 0, and then write them as is, so (5,0) and (0,-7)

1. In a two-digit number, the sun of the two digits is 10. If the two digits are reversed, the original number is less than the new number by 36. Find the original number.
2. In a two-digit number, twice the tens digit is less than the units digit by 3. If the two digits are reversed, the new number is greater than twice the original number by 18. Find the original number
1) The pairs of numbers are:
19 and 91, which do not satisfy the condition
28 and 82, which do not satisfy the condition
37 and 73, which satisfy the condition
45 and 54, which do not satisfy the condition
The number is 37.
Another method:
10x+y+36 = 10y+x, or
9x+36 = 9y, or
x+4= y …(1)
x+y = 10, or
y = 10-x …(2)
Equate (1) and (2)
x+4 = 10-x
2x = 10–4 = 6, or x = 3 so y = 10–3 = 7.
So the number is 37

Ricky is taking out a personal loan for $12,000 to remodel his kitchen. He would like the lowest monthly payment possible, even if it means a bigger finance charge in the end. His bank has offered him a loan at 13% interest for 36 months or 12% interest for 60 months, both of which are compounded monthly. Which of the following statements most accurately describes what Ricky should be thinking?
a.
More payments with the 60 month loan will give him the lowest monthly payment.
b.
Fewer payments with the 36 month loan will give him the lowest monthly payment.
c.
The 60 month loan comes with a bigger finance charge and, thus, a bigger monthly payment.
d.
The 36 month loan comes with a bigger finance charge and, thus, a bigger monthly payment.
Please select the best answer from the choices provided
A
B
C
D
Answer:
the correct answer is: a. More payments with the 60 month loan will give him the lowest monthly payment.
Step-by-step explanation:
Hope this help :) LMK
Fewer payments with the 36 monthly loan will give him the lowest monthly payment.
Option B is the correct answer.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P (1 + r/n)^{nt}
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
Ricky should choose the 36-month loan at 13% interest, which has a higher interest rate but a shorter repayment period.
This means that he will have fewer payments to make, which will result in a lower monthly payment.
The 60-month loan may have a lower interest rate, but the longer repayment period will result in a larger finance charge and a higher monthly payment.
Thus,
Fewer payments with the 36 monthly loan will give him the lowest monthly payment.

(5x2 + 23x - 7) - (x2 - 4x + 21) is equivalent to expression
4x² - 27x - 28 is the answer
Step-by-step explanation:
As per question,
(5x² + 23x - 7) - (x² - 4x + 21)
Removing the parentheses,
→ 5x² + 23x - 7 - x² + 4x - 21)
Now reorder and gather the like terms,
→ (5x² - x²) + (23x + 4x) + ( -7-21 )
Collecting the coefficients of like terms,
→ (5-1)x² - (23+4)x + ( -7-21 )
Calculating them now, we get,
→ 4x² - 27x - 28
So, (5x² + 23x - 7) - (x² - 4x + 21) = 4x² - 27x - 28
what is the 43rd term for 260,255,250
Answer:
43rd term = 50
Step-by-step explanation:
[tex]43rd \: term = 50[/tex]
The required 43rd term will be 50 in the given arithmetic sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The arithmetic sequence is given in the question as:
260, 255, 250...
This above sequence has:
The first number a₁ = 260
Common difference d = 255 - 260 = -5
The formula to find the general term of an arithmetic sequence is,
Tₙ = a₁ + (n-1)d ...(i)
Substitute the value of d = -5 and a₁ = 260 in the above formula
43rd term = 260 + (43-1)(-5)
43rd term = 260 - 42(5)
43rd term = 260 - 210
43rd term = 50
Therefore, the required 43rd term will be 50.

Answer:
minimum value = 0.001
maximum value = 10
Step-by-step explanation:
To find the minimum and maximum values for the function, substitute the endpoints of the domain into the function:
when x = -3:
[tex]\implies k(-3)=10^{-3}=0.001[/tex]
when x = 1:
