Nick was surveying his field and saw some cows and ducks. Nick counted a total of 80 heads and 248 legs. Assuming there are no mutations in the animals, determine exactly how many ducks and cows he saw. Let
X represent the number of ducks and y represent the cows.
Total Equation:
Legs Equation:
How many ducks?
How many cows?

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
