Answer:
<u>44 cows and 36 ducks.</u>
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
<u>y = 44 [There are 44 cows]</u>
Use this value to find the number of ducks:
x + y = 80
44 + y = 80
<u>y = 36 [There are 36 ducks]</u>
========================
Check:
Do 44 cows and 36 ducks have a total of 248 legs?
4*44 + 2*36 = 248 ?
176 + 72 = 248?
<u>YES</u>
Use the formula(b/2)^2 in order to create a new term. Solve for x by using this term to complete the square. The Answer is: x=3 +or- 4√2. Hope this helps
Answer: 36,960 ft
Step-by-step explanation:
Each lap around the track was a mile in distance.
Petrov therefore ran a total of 7 miles.
A mile is 5,280 feet.
If Petrov ran 7 miles in total, this distance in feet is:
= 7 * 5,280
= 36,960 ft
