Answer:
10 ft-lbs.
Step-by-step explanation:
Given data
Weight of box= 5 lb
Height moved = 2 feet
We know that the expression for work done is
Work done= Force * Distance
Work done= 5*2
Work done= 10 10 ft-lbs.
3.50/5 = .70
.70x7 = 4.90
so 7 cakes cost 4.90 pounds.
Answer: 0.7
Step-by-step explanation:
Let the number of white cows be x
Thus, the number of brown cows be (x+12)
Hence,
x+(x+12)=60
x+x+12=60
2x+12=60
2x+12-12=60-12
2x=48
Divide both parts of the equation by 2:
x=24 white cows
x+12=36 brown cows
The number of white cows are less than one year old:

The number of brown cows are less than one year old:

The total number of cows are less than one year old:

Thus
Fraction of all the cows are less than one year old:
