Answer:
47 ducks and 7 cows
Step-by-step explanation:
Ducks have 2 legs and cows have 4 legs.
If all the animals are ducks,
number of legs= 54(2)= 108
Difference in number of legs= 122 -108= 14
Difference in no. of legs per animal= 4 -2 = 2
Number of cows=14 ÷2 = 7
Number of ducks= 54-7= 47
Thus, he have 47 ducks and 7 cows.
Let's check:
Total number of feet= 7(4)+ 47(2) = 122 ✓
You could also first assume that all the animals are cows. The answer would be the same.
Answer:
13.5 m/s
Step-by-step explanation:
To start off, simply plug in the values into the equation. This is shown below...
<u>v = velocity</u>
<u>u = initial velocity</u>
<u>a = acceleration</u>
<u>t = time</u>
v = u + at ---> v = 3 + 1.5(7)
First, multiply 1.5 and 7 together. By doing so, you get 10.5. Now the equation is...
v = 3 + 10.5
To finish, simply add 3 and 10.5...
v = 3 + 10.5 ---> v = 13.5
<u>Your answer is 13.5 m/s</u>
